Abstract
An apparatus and a method are disclosed for unencumbering valuable switching resources in a network switch involved in a multipoint-to-multipoint switching scenario. The network switch includes an input processing port that is connected to a plurality of input links, and an output processing port that is connected to a plurality of output links. A data cell received on an input link is processed by the input processing port by appending a link number, a port number, and a connection identification code associated with the input processing port to the data cell. The data cell is then transferred to the output processing port where it is processed by comparing the appended link number, port number, and connection identification code with those associated with the output processing port. The data cell is then stored in a data buffering queue in the output processing port according to a matching scheme.
