摘要
An Ethernet architecture enables the transfer of data by striping individual frames across a plurality of logical channels, thus allowing operation at substantially the sum of the individual channel rates. A distributor within a sending entity's network interface distributes frame bytes in a round-robin fashion on the plurality of channels. Each mini-frame is separately framed and encoded for transmission across its channel. A receiving entity's network interface includes a collector for collecting multiple mini-frames and reconstructing the frame's byte stream. The first and last bytes of each frame and mini-frame are marked for ease of recognition. Multiple unique idle symbols may be employed for transmission during inter-frame gaps to facilitate the collector's synchronization of the multiple channels and/or enhance error detection. A maximum channel skew is specified, and each channel may be buffered with an elasticity proportional to the maximum skew so that propagation delay may be encountered between channels without disrupting communications.
