Understanding Load Balancing in Google Cloud
Load balancing in GCP is a fundamental concept that allows applications to scale, handle increased traffic, and ensure seamless user experiences. Google Cloud offers two primary types of load balancers: Network Load Balancer and HTTP Load Balancer. Let’s take a closer look at each.
Network Load Balancer: Network Load Balancer is designed to distribute traffic at the transport layer (Layer 4) by forwarding requests to backend instances based on IP address and port. It is suitable for protocols such as TCP and UDP, making it ideal for handling non-HTTP workloads. Setting up a Network Load Balancer involves several steps, including configuring forwarding rules, backend services, and health checks.
HTTP Load Balancer: HTTP Load Balancer operates at the application layer (Layer 7) and provides advanced load balancing features for HTTP and HTTPS traffic. It offers content-based routing, SSL termination, session affinity, and URL mapping capabilities. To set up an HTTP Load Balancer, you need to define backend services, target pools, forwarding rules, and configure SSL certificates if necessary.
### The Need for Cross-Region Load Balancing
Cross-region load balancing is crucial for businesses with a global reach. It enables seamless user experiences by routing traffic to the closest available server, thus reducing latency and improving load times. Additionally, it provides redundancy, ensuring that if one region experiences an outage, traffic can be rerouted to other healthy regions, maintaining the application’s availability.
### Google Cloud’s Approach to Load Balancing
Google Cloud offers a robust suite of load balancing solutions that are designed to handle the complexities of cross-region traffic distribution. Google’s HTTP(S) load balancer is a fully distributed, software-defined, managed service that supports global load balancing with a single anycast IP address. It automatically routes incoming requests to the nearest healthy backend, ensuring optimal performance and high availability.
### Setting Up Cross-Region Load Balancing on Google Cloud
To implement cross-region HTTP load balancing on Google Cloud, you need to:
1. **Create a Load Balancer:** Use the Google Cloud Console to set up a new HTTP(S) load balancer. This involves configuring the frontend, backend, and health check settings.
2. **Configure Backend Services:** Define backend services that will distribute traffic to the instances in your chosen regions. You can also set up autoscaling to dynamically adjust the number of instances based on traffic demands.
3. **Set Up URL Maps and Host Rules:** Customize how traffic is routed by setting up URL maps and host rules. This allows you to direct traffic to specific services based on the URL path or host name.
4. **Test and Monitor:** Once your setup is complete, test the load balancer to ensure it’s distributing traffic as expected. Google Cloud provides monitoring tools to help track performance and detect any issues.
Understanding SD-WAN Traffic Steering
SD-WAN traffic steering intelligently directs network traffic across multiple paths to ensure optimal performance and reliability. It involves analyzing network conditions, application requirements, and other factors to make informed routing decisions. SD-WAN traffic steering provides enhanced performance and flexibility by dynamically routing traffic based on real-time conditions.
Load Balancing: Load balancing is a fundamental traffic steering technique in SD-WAN. It involves distributing traffic across multiple paths to avoid congestion and maximize bandwidth utilization. SD-WAN devices intelligently monitor network conditions and dynamically adjust traffic distribution, ensuring efficient utilization of available resources.
Application-Aware Routing: Traditional routing techniques treat all traffic equally, regardless of the application type or priority. However, SD-WAN introduces application-aware routing, where traffic is routed based on application requirements. By prioritizing critical applications and allocating network resources accordingly, SD-WAN optimizes performance and user experience.
Performance-Based Routing: SD-WAN leverages performance-based routing to dynamically select the best path for network traffic. This technique continuously monitors factors such as latency, jitter, and packet loss to assess the quality of each available path. SD-WAN ensures consistent and reliable performance by intelligently routing traffic through the most optimal path.
Policy-Based Routing: Policy-based routing allows network administrators to define specific rules and policies for traffic steering. These policies are based on factors such as application type, user groups, or security requirements. SD-WAN devices enforce these policies to route traffic according to the predefined rules, providing granular control over network traffic.
Understanding EIGRP Load Balancing
– EIGRP (Enhanced Interior Gateway Routing Protocol) is a dynamic routing protocol widely used in enterprise networks. Load balancing refers to the distribution of traffic across multiple paths, allowing for efficient utilization of available network resources. EIGRP load balancing achieves this by dividing traffic between numerous equal-cost paths, ensuring optimal utilization and enhancing network performance.
– Several factors must be considered to enable load balancing in EIGRP. First, the network topology must have multiple paths with equal metrics. This can be achieved by adjusting link costs or using equal-cost multipath (ECMP) techniques. Second, the router interfaces involved in load balancing should be configured to support it. This typically involves enabling EIGRP and specifying load-balancing parameters such as maximum-paths and variance.
– EIGRP offers different load-balancing algorithms to distribute traffic across multiple paths. These algorithms include per-packet load balancing, per-destination load balancing, and per-source/destination load balancing. Each algorithm has advantages and considerations, depending on the network requirements and characteristics. Understanding these algorithms is crucial for effective load-balancing implementation.
Understanding BGP AS Prepend
AS Prepending is a method for influencing routing path selection by adding additional AS numbers to the AS_PATH attribute. By manipulating the AS_PATH, network administrators can influence BGP routers to prefer specific paths. This technique is beneficial for directing traffic away from congested or underperforming links.
AS Prepending offers several advantages in network optimization. Firstly, distributing traffic across multiple paths allows for better load balancing. By strategically prepending AS numbers, you can encourage BGP routers to select alternate paths, optimizing network performance. Secondly, AS Prepending helps in traffic engineering, enabling you to control traffic flow and avoid congestion. Lastly, this technique improves network resilience by providing redundancy and failover capabilities.
Advanced Topics
Shortest-path routing
Every dynamic network backbone has some congested links, while others still need to be utilized. That’s because shortest-path routing protocols transmit traffic down the shortest path without regarding other network parameters, such as utilization and traffic demands. So, we need to employ application traffic engineering or traffic steering to use our network links.
Using Traffic Engineering (TE), we can redistribute packet flows to attain a more uniform distribution across all links in our network. Forcing traffic onto specific pathways lets you get the most out of your current network capacity while making it easier to deliver consistent service levels.
SDN-based Architecture
Many protocol combinations produce an SDN-based architecture to enable application traffic steering; native OpenFlow is only one of those protocols. Some companies view OpenFlow as a core SDN design component while others don’t even include it, aka BGP SDN controller and BGP SDN. For example, the Forwarding and Control Element Separation ( ForCES) working group has spent several years working on mechanisms for separating the control and data plane.
The role of OpenFlow
They created their southbound protocol and didn’t use OpenFlow to connect the data and control planes. On the other hand, NEC was one of the first organizations to take full advantage of the OpenFlow protocol. The market’s acceptance of SDN use cases has created products that fall into an OpenFlow or non-OpenFlow bucket. The following post discusses traffic steering that outright requires OpenFlow.
The OpenFlow protocol offers additional granular control to steer traffic through an ordered list of user-specific services. A task that traditional IP destination-based forwarding struggles to do efficiently. OpenFlow offers additional flow granularity and provides topology-independent service insertion required by network overlays, such as a VXLAN.
Understanding OpenFlow Traffic Steering
OpenFlow traffic steering involves intelligently directing network traffic flows within an SDN environment. By separating the control plane from the data plane, OpenFlow allows for centralized management and programmability of network devices. This enables granular control over routing decisions, flow prioritization, and traffic optimization.
Enhanced Network Flexibility: OpenFlow traffic steering empowers administrators to adapt and reconfigure their networks to meet changing demands dynamically. This flexibility improves scalability, reduces network congestion, and enhances overall network performance.
Efficient Traffic Management: With OpenFlow, traffic can be intelligently routed based on specific criteria such as quality of service (QoS), latency requirements, or security policies. This fine-grained control optimizes network utilization, minimizes packet loss, and improves end-to-end performance.
Simplified Network Operations: OpenFlow simplifies network operations by centralizing network control, reducing the complexity associated with traditional distributed routing protocols. Administrators can define traffic policies and implement changes across the network from a single management interface, thus streamlining network management tasks.
Implementing OpenFlow Traffic Steering
Network Infrastructure Requirements: Organizations need compatible network devices that support the OpenFlow protocol to implement OpenFlow traffic steering. These devices include OpenFlow-enabled switches and routers, which can be sourced from various vendors.
OpenFlow Controller Selection: It is crucial to select an appropriate OpenFlow controller. Popular choices include OpenDaylight, Ryu, and Floodlight. The OpenFlow controller acts as the brain of the network, managing traffic and enforcing policies based on predefined rules.
Rule Definition and Flow Configuration: Network administrators must define traffic flow rules within the OpenFlow controller. These rules specify how traffic should be handled, including routing decisions, QoS parameters, and any required packet modifications. Careful planning and rule design are essential to achieving desired traffic steering outcomes.

The Role of Load Balancers:
Load balancing serves as the backbone of Application Traffic Steering. They act as intermediaries between clients and servers, receiving incoming requests and distributing them across multiple servers based on specific algorithms. These algorithms consider server load, response time, and availability to make informed decisions.
Application Traffic Steering Techniques:
1. Round Robin: This algorithm distributes traffic evenly across all available servers in a cyclic manner. While it is simple and easy to implement, it does not consider server load or response times, which may result in uneven distribution and suboptimal performance.
2. Least Connections: This algorithm directs traffic to the server with the fewest active connections at a given time. It ensures optimal resource utilization by distributing traffic based on the server’s current load. However, it doesn’t consider server response times, which may lead to slower performance on heavily loaded servers.
3. Weighted Round Robin: This algorithm assigns weights to servers based on their capabilities and performance. Servers with higher weights receive a larger share of traffic, enabling organizations to prioritize specific servers over others based on their capacity.
Multicast Traffic Steering
Multicast traffic steering is a technique for efficiently directing data packets to multiple recipients simultaneously. It is beneficial in scenarios where a single source needs to transmit data to various destinations. Instead of sending individual copies of the data to each recipient, multicast traffic steering enables the source to transmit a single copy efficiently distributed to all interested recipients.
Lab Guide on IGMPv1
IGMPv1 is a communication protocol that enables hosts on an Internet Protocol (IP) network to join and leave multicast groups. Multicast groups allow the simultaneous transmission of data packets from a single sender to multiple recipients.
By utilizing IGMPv1, hosts can efficiently manage their participation in multicast groups and receive relevant data from senders.
Below, we have one router and two hosts. We will enable multicast routing and IGMP on the router’s Gigabit 0/1 interface.
- First, we enabled multicast routing globally; this is required for the router to process IGMP traffic.
- We enabled PIM on the interface. PIM is used for multicast routing between routers and is also required for the router to process IGMP traffic.
Benefits of Multicast Traffic Steering:
1. Bandwidth Efficiency:
Multicast traffic steering reduces network congestion and optimizes bandwidth utilization. By transmitting a single copy of the data, it minimizes the duplication of data packets, resulting in significant bandwidth savings. This is especially advantageous in scenarios where large volumes of data must simultaneously be transmitted to multiple destinations, such as video streaming or software updates.
2. Scalability:
In networks with many recipients, multicast traffic steering ensures efficient data delivery without overwhelming the network infrastructure. Instead of creating a separate unicast connection for each recipient, multicast traffic steering establishes a single multicast group, reducing the burden on the network and enabling seamless scalability.
3. Reduced Network Latency:
Multicast traffic steering reduces network latency by eliminating the need for multiple unicast connections. Data packets are delivered directly to all interested recipients, minimizing the delay caused by establishing and maintaining individual connections for each recipient. This is particularly crucial for real-time applications, such as video conferencing or live streaming, where low latency is essential for a seamless user experience.
Traditional Layer 2 and Layer 3 Service Insertion
Example: Traditional Layer 2
In a flat Layer 2 environment, everybody can reach each other by their MAC address. There is no IP routing. If you want to intercept traffic, the switch in the middle must intercept and forward to a service device, such as a firewall.
The firewall doesn’t change anything; it’s a transparent bump in the wire. You would usually insert the same service in both directions so the firewall will see both directions of the TCP session. Service insertion at Layer 2 is achieved with VLAN chaining.
For example, VLAN-1 is used on one side and VLAN-2 on the other; different VLAN numbers link areas. VLAN chaining is limited and impossible to implement for individual applications. It is also an excellent source for creating network loops. You may encounter challenges when firewalls or service nodes do not pass the Bridge Protocol Data Unit (BPDU). Be careful to use this for large-scale service insertion production environments.
Example: Layer 3 Service Insertion
Layer 3 service insertion is much safer as forwarding is based on IP headers, not Layer 2 MAC addresses. Layer 3 IP headers have a “time-to-live” field that prevents loops from looping around the network. Layer 2 frames are redirected to a transparent or inter-subnet appliance.
This means the firewall device can do a MAC header rewrite on layer 2, or if the firewall is placed in different subnets, the MAC rewrite would be automatic as you will be doing layer 3 forwardings. Layer 3 service insertion is typically implemented with Policy-Based Routing (PBR).
“User-specific services may include firewall, deep packet inspection, caching, WAN acceleration and authentication.”
Application traffic steering, service function chaining, and dynamic service insertion
Application traffic steering, service function chaining, and dynamic service insertion functionally mean the same thing. They want to insert networking functions based on endpoints or applications in the forwarding path.
Service chaining applies a specific list of ordered services (service changing) to individual traffic flows. The main challenge is the ability to steer traffic to various devices. Such devices may be physical appliances or follow the Network Function Virtualization (NFV) format.
Designing with traditional mechanisms leads to cumbersome configurations and multiple device touchpoints. For example, service appliances that need to intercept and analyze traffic could be centralized in a data center or service provider network. Service centralization results in users’ traffic “tromboning” to the central service device for interaction.
Traffic tromboning
Traffic tromboning may not be an issue for data center leaf and spine architecture with equidistant endpoints. However, other aggregated network designs that don’t follow the leaf and spine model may run into interesting problems. A central service network point also represents a “choking point” and may increase path latency. Service integration should be flexible and not designed with a “meet me” architecture.
- The requirement for “flow” level granularity
Traditional routing is based on destination-based forwarding and cannot provide the granularity needed for topology-independent traffic steering. You may implement tricks with PBR and ACL, but they increase complexity and have vendor-specific configurations. Efficient traffic steering requires a granular “flow” level of interaction, which is not offered by default destination-based forwarding.
The requirement for large-scale cloud networks drives multitenancy, and network overlays are becoming the defacto technology used to meet this requirement. Network overlays require new services to be topology-independent.
Unfortunately, IP routing is limited, and different types of traffic going to the same destination cannot be distinguished. Traffic steering based on traditional Layer 2 or 3 mechanisms is inefficient and does not allow dynamic capabilities.
SDN Adoption
A single OpenFlow rule pushed down from the central SDN controller provides the same effect as complex PBR and ACL designs. Traffic steering is accomplished with OpenFlow at an IP destination or IP flow layer of granularity. This dramatically simplifies network operations as there is no need for PBR and ACL configurations. There is less network and component state as all the rules and intelligence are maintained at the SDN central controller.
A holistic viewpoint enables singular points for configuration, not numerous touchpoints throughout the network. A virtual switch, such as the Open vSwitch, can be used for data. It is a multi-layered switch that is highly well-featured.
There are alternatives for pushing ACL rules down to network devices, such as RFC 5575 and Dissemination of Flow Specification Rules. It works with a BGP control plane (BGP flow spec) that can install rules and ACL to network devices.
One significant difference between BGP flow spec and OpenFlow for traffic steering is that the OpenFlow method has a central control policy. BGP flow spec consists of several distributed devices, and configuration changes will require multiple touchpoints in the network.
