PACKET SIZE CONTROL USING MAXIMUM TRANSMISSION UNITS FOR FACILITATING PACKET TRANSMISSION

摘要

A system and method of facilitating packet transmission comprises a first node, a second node, and an intermediate node. The intermediate node receives a first packet, from the first node, determines a packet size, determines a maximum transmission unit (MTU) size, and determines whether the packet size is greater than the MTU size, sends a second packet to the first node specifying the MTU size to the first node. The first node records a destination mark at the first node, including the MTU size and an identifier of the second node, fragments the first packet into a plurality of fragmented packets, and sends each of the plurality of fragmented packets to the intermediate node. The intermediate node receives each of the plurality of fragmented packets, from the first node, and sends the fragmented packets to the second node.

1. A method of facilitating packet transmission, the method comprising:
receiving a first packet, from a first node, at an intermediate node; determining a packet size, wherein the packet size is a size of the first packet received from the first node; determining a maximum transmission unit (MTU) size for a second node, wherein the MTU size is a defined maximum packet size that can be transmitted to the second node; determining whether the packet size is greater than the MTU size; responsive to determining that the packet size is greater than the MTU size:
sending a second packet, to the first node, the second packet specifying the MTU size to the first node, wherein the first node:
records a destination mark at the first node, wherein the destination mark includes the MTU size and an identifier of the second node,fragments the first packet into a plurality of fragmented packets, wherein the fragmented packets have packet sizes less than or equal to the MTU size, andsends each of the plurality of fragmented packets to the intermediate node, andreceiving each of the plurality of fragmented packets from the first node; and sending the fragmented packets to the second node.
