Abstract

A method and device for combining packets is disclosed. In various embodiments, a plurality of packets that are compliant with a particular protocol are combined into a single packet of the same protocol. The single packet also preserves identification information for each of the combined packets within the single packet. The identification information can be used to partition and / or route the combined packets to their respective destinations.

Description

technical field [0001] Embodiments disclosed herein relate generally to packet transmission, and more particularly to methods, devices, and systems for combining packets prior to transmission. Background technique [0002] Data can be sent in many different forms within a computer system or between computer systems (eg, over a network). In some systems, data is aggregated and sent as a package. PCI Express (Peripheral Component Interconnect Professional Group's Peripheral Component Interconnect Express 1.0 Specification, published July 22, 2002) is an example of a protocol for packetizing and transferring data. Regardless of the protocol used, packet transmission requires some degree of overhead and a minimum packet size. [0003] For example, some packets require a header (eg, overhead) that contains information about the contents and / or destination of the packet. If a minimum packet size is required before sending the packet, some systems will "pad" extra bits in packet...
