Bus scaling device

摘要

A scaling device or striper improves the lane efficiency of switch fabric. The striper controls or adjusts transfer modes and payload sizes of a large variety of devices operating with different protocols. The striper interfaces between network devices and the switch fabric, and the resulting switching system is configurable by a single controller. A source device sends a data packet to its corresponding striper for transmission across the switch fabric to a destination device. The corresponding striper parses the packet to determine its type and payload length, and divides the packet into numerous smaller segments when the payload length exceeds a predetermined length. The segments may be stored in the striper to adapt to the available bandwidth of the switch. The segments are sent across the switch fabric and reassembled at a destination striper. The packet as reassembled is forwarded to the destination device.
