Application Optimization – TCP Optimization

A person in a black shirt stands in front of a clear lightboard with a green banner above them that reads "Lightboard Lesson Application Optimization Functionalities." The video thumbnail is branded with the "open systems" logo in the top right corner.

TCP Optimization adjusts the congestion control algorithm of the WAN link to one that is more suitable for ISP lines with high latency or high levels of packet loss. This allows the throughput to be maintained at a higher level than when using standard congestion control algorithms which do not cope well with these types of lines.

Transcript

Hi, I’m Thomas. Welcome to the lightboard session on application optimization. Application optimization is based on TCP optimization. When a client establishes a connection to a server, we intercept that session and establish a new session between the Open Systems edge devices. The edge device then establishes the session to the server.

Since we control the TCP connection between the two edge devices, we can ensure the use of a TCP algorithm that is designed to provide optimal performance, even in cases where the line suffers from packet loss or high latency. By optimizing at the TCP level, we can also provide optimization for your encrypted applications, where other optimization options may not be available.
