TCP Tuning Domains
Transport Control Protocol (TCP) tuning is complicated because there are many algorithms running and controlling TCP data transmissions concurrently, each with slightly different purposes.
FIGURE 3-1 shows a high-level view of the different components that impact TCP processing and performance. While the components are interrelated, each has its own function and optimization strategy.
The STREAMS framework looks at raw bytes flowing up and down the streams modules. It has no notion of TCP, congestion in the network, or the client load. It only looks at how congested the STREAMS queues are. It has its own flow control mechanisms.
TCP-specific control mechanisms are not tunable, but they are computed based on algorithms that are ...
