ABSTRACT
Network administrators need a thorough understanding of both types of addressing to administer Transmission Control Protocol/Internet Protocol (TCP/IP) networks and troubleshoot TCP/IP-based communication. This chapter discusses in detail the types of Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6) addresses, how they are expressed, and the types of unicast addresses assigned to network node interfaces.
We demonstrate that the dynamic behavior of queue and average window is determined predominantly by the stability of TCP/IP, not by AIMD probing nor noise traffic. We develop a general multi-link multi-source model for TCP/IP and derive a local stability condition in the case of a single link with heterogeneous sources. We validate our model with simulations and illustrate the stability region of TCP/IP. These results suggest that TCP/IP becomes unstable when delay increases, or more strikingly, when link capacity increases. The analysis illustrates the difficulty of setting IP parameters to stabilize TCP: they can be tuned to improve stability, but only at the cost of large queues even when they are dynamically adjusted. Finally, we present a simple distributed congestion control algorithm that maintains stability for arbitrary network delay, capacity, load and topology. The behavior of the TCP protocol in simple situations is well-understood, but when multiple connections share a set of network resources the protocol can exhibit surprising phenomena. Earlier studies have identified several such phenomena, and have analyzed them using simulation or observation of contrived situations.
