High speed flow control methodology

A method and apparatus for controlling data flow across a network performs a method which includes transmitting a packet request message from a first station to a second station, then determining if the packet request message is valid. A request acknowledge message is transmitted from the second station to the first station, and it is then determined if the request acknowledge message is valid. The packet request message and the request acknowledge message each includes a control bit string, an identification bit string, and at least one parity bit.

Serializing data using hazard-free multilevel glitchless multiplexing

A network switch having an Internet port interface controller, includes a high performance interface for communicating with other switches and components through the transfer of data packets contained in memory. The high performance interface includes a data connection bus, where data is transferred on both a rising edge and a falling edge of a clock signal, and the data connection bus has output drivers and a multiplexing circuit connected to the output drivers. The multiplexing circuit is constructed through two levels of glitchless multiplexors, to serialize said data transmitted over said high performance interface. Because two levels of glitchless multiplexors are employed, function hazards that occur in the glitchless multiplexors when more than one input thereto change simultaneously can be masked, and do not create noise that can be propagated to an output driver.
