Quality of Service and performance characterization of IPv6 relative to IPv4

CHAPTER IV: QUALITY OF SERVICES, TEST AND ANALYSIS

IV.1 INTRODUCION

The purpose of this chapter that is the main part of this book is to give a look on this new technology. The transition mechanisms have been tested, a network analyzer has been used to analyze the traffics that are passing through our test Lab. Another major reason of this chapter is to train readers of this book to be familiar with the evolution of network technology.

IV.2 NETWORK REQUIREMENTS

This section sets out to outline the requirements of IPv6 network. The IPv6 network involves different components:

IV.2.1 Operating Systems

Most of the modern operating systems now have two distinct IP stacks to support both IPv4 and IPv6 at the same time. The list below shows the list of platforms that supports IPv6 applications.

· Windows XP: Windows XP has IPv6 built in

· Windows 2000: Microsoft that release IPv6 runs on Windows 2000. It does not work on Windows 95/98.

· Windows VISTA: IPv6 has been fully incorporated into the operating system, it is installed by default.^41(*)

· Linux: The All the Linux distribution are based on Kernel (Kernel is the base operating system, which interacting directly with the hardware and services of user programs) identified by its version. The Linux kernel has supported IPv6 since version 2.2.x.

· Sun Solaris: IPv6 support is available from Solaris version 8.

IV.2.2 Applications and Services

Networked applications and services must be modified, or ported, to support IPv6.

Cisco routers and switches running one of the following Cisco IOS Software releases are IPv6-capable: Cisco IOS Software releases 12.2T, 12.3M, 12.3T, 12.4M, 12.4T, 12.2S (and derivatives), 12.0S .Cisco 12000 Series routers and Cisco 10720 Router. Cisco IOS-XR Software (Cisco Carrier Routing System-CRS-1, Cisco XR 12000 Series Router).^42(*)
