Flow control using output port buffer allocation

摘要: A system for implementing flow control in an information network such as a local area (LAN) utilizing Carrier Sense Multiple Access with Collision Detection (CSMA/CD) specified by the IEEE standard 802.03. The transmits computer data between various systems coupled to network. includes switches capable of routing packets received via its input ports output ports. are held buffers before being transmitted portion each port buffer is allocated port. switch provides packet PAUSE frame upstream source operably response level occupancy exceeding first level. inhibits from transmitting In one system, has capability ignoring when exceeds threshold
