Detailed Description

Contains state variables ("TCB") for TCP.

TcpStateVariables is effectively a "struct" – it only contains public data members. (Only declared as a class so that we can use cObject as base class and make it possible to inspect it in Tkenv.)

TcpStateVariables only contains variables needed to implement the "base" (RFC 793) TCP. More advanced TCP variants are encapsulated into TcpAlgorithm subclasses which can have their own state blocks, subclassed from TcpStateVariables. See TcpAlgorithm::createStateVariables().
