Much of the traffic that is going through NetScaler is based on the TCP protocol. Either it is ICA-Proxy, HTTP, or something similar.
TCP is a protocol that provides a reliable, error-checked delivery of packets back and forth. This ensures that data is successfully transferred before being processed further. TCP has many features to adjust bandwidth during transfer, congestion checking, adjusting segment sizing, and so on, which we will delve into a bit in this section.
As mentioned in an earlier chapter, we can adjust the way NetScaler uses TCP using TCP profiles. By default, all services and vServers that are created on the NetScaler use the default TCP profile
These profiles can be found under System | Profiles ...
