Follow on Google News | Internet Technologies Handbook Volume 1 - Infrastructure 2007This report is a technical introduction, for people without an engineering background, to the Internet’s infrastructure and to its major protocols and applications.
By: Sunil Nair Report also contains discussion of: • Contemporary and future impact. • Major challenges, including spam, botnets and the crisis in routing and addressing. • Tutorial on web-browsing example of client-server HTTP communications. • Choosing a hosting company. • Delegating a domain. Executive Summary We begin with an overview of the Internet’s future, including two challenges to its continuing stability – the crisis in routing and addressing and the proliferation of ‘botnets’: criminally controlled networks of hundreds of thousands of home and office computers which are used for spam, fraud and denial of service attacks. The crisis in routing and addressing involves the imminent depletion of fresh IPv4 address space around 2012 and difficulties with the core Internet routers and the border routers of the networks of ISPs and major organisational users. The global routing system is not expected to cope well with the continual increase in the current 200,000 separately routed divisions of the IPv4 address space. IPv6 routing will be even more problematic if and when its adoption becomes ubiquitous. The current approaches to addressing and routing are failing to keep up with the needs of the growing number of interconnected networks, including especially those which require multihoming: We describe the basics of Transmission Control Protocol/Internet Protocol (TCP/IP), User Datagram Protocol (UDP) and TCP packets, which are the basis of all Internet communications. We also discuss how IPv6, the next generation of Internet addressing, may be adopted. IPv6’s widespread adoption for servers and desktop computers is far from assured, with concern about routing problems and with the difficulties inherent in two-stack adoption. However IPv6 is likely to be widely used in China, for some new cellular mobile networks and for proposed new generations of IP-equipped appliances and devices.
