ABSTRACT

The segments which are a divided data packets do not have a specific segment size but mostly the default packet (segment) size is 1500 bytes. Which may be found less than the segment size of certain router on the path specified to the host destination, where unfortunately the maximum transmission unite (MTU) of each router differs from one to another, according to the protocol used and the type of network causing the segment to be fragmented by an intermediate router. This paper presents a novel cross layer design to eliminate fragmentation process from occurring at intermediate router, by providing information on the minimum MTU from source to destination in advanced to avoid the fragmentation process, that occurs when a segment (packet) is larger than the MTU of an intermediate router. The idea is to maintain information on minimum MTU allowance in forwarding table of every router. Therefore, for the purpose of maintaining information on MTU, the work proposes a routing table with four columns to perform path routing along with the minimum MTU on the path instead of the existing three columns forwarding table. which does not provide information on the MTU allowance.
