WiMAX Network Layer

Abstract

This chapter describes the networking protocols that complement the end-to-end functions of WiMAX technology together with PHY and MAC signaling of IEEE 802.16 standard, described in the previous two chapters, respectively. WiMAX Forum, which is constituted by the companies, formed Working Groups to de- fine the networking protocols and facilitate the adoption of WiMAX technology. Networking Working Group is responsible to develop the networking architecture in conjunction with other groups, especially with Service Provider Working Group that basically defines the desired level of standards by the operators. This chapter is adapted from WiMAX Forum documents with permission. The topics presented in this chapter are derived from published Stage 2 and Stage 3 specifications for Release 1 Version 1.2. Also, this chapter contains information about ongoing developments of Release 1.5 in brief. We advice the user that although information from WiMAX Forum Stage 2 and Stage 3 documents is up to date, final versions of these specifications may contain minor changes.
