What are the load balancing algorithms?

Load Balancing Algorithms and Techniques

  • Round Robin. Round-robin load balancing is one of the simplest and most used load balancing algorithms.
  • Weighted Round Robin.
  • Least Connection.
  • Weighted Least Connection.
  • Resource Based (Adaptive)
  • Resource Based (SDN Adaptive)
  • Fixed Weighting.
  • Weighted Response Time.

Is Load Balancer a hardware or software?

Like servers, load balancing appliances can be physical or virtual. Physical (hardware load balancing) and virtual (software load balancing) appliances both evaluate client requests and server usage in real time and send requests to different servers based on a variety of algorithms.

What is Layer 7 load balancing?

An Layer 7 load balancer works at the application layer—the highest layer in the OSI model—and makes its routing decisions based on more detailed information such as the characteristics of the HTTP/HTTPS header, message content, URL type, and cookie data.

How do I check my F5?

Note: For information about displaying the version information for other F5 products, refer to K914: Displaying the software version of your F5 product. Go to System > Configuration. The software version displays in the Version box.

How does F5 check active connections?
