Load Balancing is pivotal for ensuring the availability of the network to users. It works as an aware routing protocol in Software-defined networking (SDN) to assist the scalability and availability leads to obtaining minimal application response time.
The SDN-based load balancing becomes more efficient and smart to reduce the statistic collection overhead and maintain better QoS data rates. The SDN load balancing is very lightweight regarding utilization and time intervals. It provides better features during data transmitting and receiving from one server to another server, such as,
• Stability
• Scalability
• Reliability
The load balance is presented with Round Robin Strategy to direct the routing-based algorithm by maximizing the throughput and minimizing the response time interval to reduce the jam. The SDN-based load balancing consists of some parameters that include,
• Delay
• Bandwidth
• Overloaded ratio
• Distance and cost metric
• Flow arrival rate in flow duration
• Response throughput transaction rate
Benefits of SDN based Load Balancing include,
• Avoiding bottlenecks
• Minimize response time
• Maximize the throughput
• Optimize resource utilization
• Decrease transmission latency
• Enhances end-to-end network Quality-of-services (QoS)
Applications of SDN based Load Balancing include,
• Traffic monitoring provided the required data to alert the drivers regarding problems and statics essential to engineers, like speed, occupancy, and vehicle count.
• Security enhancement is an improvement of abilities and offerings beyond basic specifications. SDN controller allows the topology discovery in service to provide and maintain a global view of networks.
