The battle between standards: TCP/IP vs OSI victory through path dependency or by quality?

Between the end of the 1970s and 1994 a fierce competition existed between two possible standards, TCP/IP and OSI, to solve the problem of interoperability of computer networks. Around 1994 it became evident that TCP/IP and not OSI had become the dominant standard. We specifically deal with the question whether the current dominance of the TCP/IP standard is the result of third degree path dependency or of choices based on assessments of it being technical-economically superior to the OSI standard and protocols

Reverse Engineering TCP/IP-like Networks using Delay-Sensitive Utility Functions

TCP/IP can be interpreted as a distributed primal-dual algorithm to maximize aggregate utility over source rates. It has recently been shown that an equilibrium of TCP/IP, if it exists, maximizes the same delay-insensitive utility over both source rates and routes, provided pure congestion prices are used as link costs in the shortest-path calculation of IP. In practice, however, pure dynamic routing is never used and link costs are weighted sums of both static as well as dynamic components. In this paper, we introduce delay-sensitive utility functions and identify a class of utility functions that such a TCP/IP equilibrium optimizes. We exhibit some counter-intuitive properties that any class of delay-sensitive utility functions optimized by TCP/IP necessarily possess. We prove a sufficient condition for global stability of routing updates for general networks. We construct example networks that defy conventional wisdom on the effect of link cost parameters on network stability and utility

A TCP/IP Network Emulator

In this paper a Linux based framework of a TCP/IP emulator is introduced. Several advantages can be noted. Firstly, the maintenance of large numbers of processors is unnecessary. Secondly, compared with simulators constructed with conceptual codes, our emulator framework makes it possible to test the interaction and behaviour of TCP/IP in real Linux network environments. Thirdly, the wired network is fully controlled by a single processor enabling us to separate TCP/IP behaviour over the wireless network, which helps distinguish performance functions that occur due to noisy wireless links. The framework was tested on two Linux processors over an IEEE802.11b wireless link. The simulations show that the complex topology of the heterogeneous network was "realistically" constructed

TCP/IP XML Solution

Since its introduction, Extensible Markup Language (XML) has evolved and helped us evolve in the way which we think about structuring, describing, and exchanging information. The ways in which XML is used in the software industry are many and growing. For example, for Web services the importance of XML is crucial; all key Web service technologies are based on it. In this paper it’s presented a TCP/IP XML solution for integrating an intermediary trading system with the Bucharest Stock Exchange trading system. The solution is presented from the intermediary point of view and can be the first step of a complete SOA solution.TCP/IP, XML, Bucharest Stock Exchange, Java

TCP/IP Implementation within the Dartmouth Scalable Simulation Framework

This paper discusses TCP/IP networking, and in particular, the DaSSF implementation of TCP/IP. The paper reviews the protocols, outlines the implementation design, and demonstrates some tests. In addition, some performance and memory usage analysis is performed. We find DaSSF TCP/IP to be a viable option to the existing SSF. DaSSF TCP/IP is faster and uses less memory so we can simulate larger, more complex, models

TCPSnitch: Dissecting the Usage of the Socket API

Networked applications interact with the TCP/IP stack through the socket API. Over the years, various extensions have been added to this popular API. In this paper, we propose and implement the TCPSnitch software that tracks the interactions between Linux and Android applications and the TCP/IP stack. We collect a dataset containing the interactions produced by more than 120 different applications. Our analysis reveals that applications use a variety of API calls. On Android, many applications use various socket options even if the Java API does not expose them directly. TCPSnitch and the associated dataset are publicly available.Comment: See https://www.tcpsnitch.or
