Load balancing improves network performance by distributing traffic efficiently so that individual servers are not overwhelmed by sudden fluctuations in activity. Server Load Balancing is a guide to this critical component of high availability, clustering, andfault tolerance, all of which provide the infrastructure for reliable Internet sites and large corporate networks.Much of the information on load balancing comes from vendor-specific manuals that use inconsistent terminology and are often biased toward the products they cover. Server Load Balancing...

This concise guide offers the basic concepts of IP routing, free of hype and jargon. It begins with the simplest routing protocol, RIP, and then proceeds, in order of complexity, to IGRP, EIGRP, RIP2, OSPF, and finally to BGP. New concepts are presented one at a time in successive chapters. By the end, you will have mastered not only the fundamentals of all the major routing protocols, but also the underlying principles on which they are based.The basic information in IP Routing is designed to help you begin configuring protocols for Cisco routers. Although author Ravi Malhotra...

Large IT organizations increasingly face the challenge of integrating various web services, applications, and other technologies into a single network. The solution to finding a meaningful large-scale architecture that is capable of spanning a global enterprise appears to have been met in ESB, or Enterprise Service Bus. Rather than conform to the hub-and-spoke architecture of traditional enterprise application integration products, ESB provides a highly distributed approach to integration, with unique capabilities that allow individual departments or business units to build out their...

Domino is one of the most effective platforms for developing and deploying e-business applications, allowing new communities of developers to enjoy its collaborative capabilities. With over 55 million seats worldwide, Domino already provided a strong foundation for messaging and web applications, and the release of R5 builds on that to make Domino easier to use than ever before.For example, Lotus Domino R5 has been expanded to interact with most browsers and other non-Notes clients, so developers can choose their favorite language to design web applications. With R5, administrators can...

Dynamic Host Configuration Protocol (DHCP) is an open standard Internet protocol used to allocate and manage IP addresses dynamically. Before DHCP came along, administrators had to manually configure each host on a network with an IP address, subnet mask, and default gateway. Maintaining the changes and the associated logs took a tremendous amount of time and was prone to error. DHCP uses a client/server model in which the system updates and maintains the network information dynamically. Windows 2000 provides enhanced DHCP client-server support.DHCP for Windows 2000 is...

Get started with Twisted, the event-driven networking framework written in Python. With this introductory guide, you ll learn the key concepts and design patterns to build event-driven client and server applications for many popular networking protocols. You ll also learn the tools to build new protocols using Twisted s primitives.

Start by building basic TCP clients and servers, and then focus on deploying production-grade applications with the Twisted Application infrastructure. Along the way, you can play with and extend examples of common tasks you ll face when building network...
