A Quantitative Procedure of Optimizing the MAC Packet Size in TCP/IP-Compliant Networks

10.1  Background

Consider a TCP/IP session optimization problem in networks in which each MAC packet is transmitted completely over one link before starting transmission to the next. Following Bertsekas and Gallager [1], such networks will be called cut-through routing-free networks or CTRF networks. Examples of CTRF networks are those compliant with IEEE 802.11 wireless LAN [2] or IEEE 802.16 wireless MAN [3] standards. Contrarily, a typical wire line network (for instance, IEEE-802.3-compliant one) is a cut-through routing (CTR) kind of network. In CTR networks, a node starts relaying any portion of a packet to another node without waiting ...
