Abstract:
A method of preparing packets queued at a first node for transmission to a second node, wherein a maximum transmission unit (MTU) of the path between said first node and second node is known, and said method includes:A. classifying a set of said packets as a function of having a common second node in a transmission path of each packet in said set of packets, wherein said second node is configured to de-encapsulate said set of packets; B encapsulating said set of packets into an encapsulation payload; C. deriving an encapsulation packet header from said encapsulation payload, said encapsulation packet header including a destination address; D. combining said encapsulation packet header with said encapsulation payload to form an encapsulation packet, E. determining whether said encapsulation packet exceeds said MTU, and F. if said MTU is exceeded, eliminating one or more packets from said set of packets to form a new set of packets and repeating parts B through F.
