Method and apparatus for ensuring cell ordering in large capacity switching systems and for synchronizing the arrival time of cells to a switch fabric |
摘要 |
Where links between a port module and plural switch fabric slices are of various lengths, a cell is transmitted from the port module to a switch fabric slice in response to a grant. The transmission is delayed by an amount based on a link round trip delay (RTD) value for the corresponding link between the port module and the switch fabric slice, and a predetermined global delay value. As a result of this delay, the cell arrives at the switch fabric slice at a fixed number of cell times (equal to the global delay value) after issuance of the grant, independent of any link lengths.
