Abstract
Methods for providing flow control of signal streams over a single full duplex ETHERNET link include receiving multiple data streams over a single ETHERNET link, associating a buffer with each data stream, putting received data into the appropriate buffer, monitoring the fullness of the buffers, and transmitting a PAUSE frame to the source of the data streams where the PAUSE frame indicates the fullness of each buffer. The PAUSE frame is read and where indicated, the transmission of data destined for a congested buffer(s) is halted until a subsequent PAUSE frame is received which indicates that the congested buffer(s) has become decongested. Apparatus for performing the methods are also provided.
