Abstract: A bridge interfaces a first network protocol and a second network interface protocol. Each of a plurality of mapping windows is defined by corresponding mapping parameters defining a space in the first protocol and defining the mapping window translation rules to the second network protocol. Transaction requests in the first network protocol are selectively associated with the mapping windows.

Abstract: A method and apparatus for buffering data units in a communication switch that allows for configurable monitoring of the buffer contents is presented. Such an apparatus includes a context table that stores a plurality of independent group identifiers for each connection. Although the group identifiers may include a partition group identifier and a loss group identifier that is dependent on the partition group identifier, additional group identifiers are included in the context table for each connection that are independent of other group identifiers in the context table. Such a context table may be dynamically reconfigured in order to group connections for buffer monitoring operations related to congestion detection, traffic shaping, and data admission with respect to buffering. When a data unit is received corresponding to a particular connection, the context table is referenced to retrieve the set of group identifiers corresponding to that connection.

Abstract: A method and apparatus includes processing for combining a plurality of virtual circuits into a combined virtual circuit, where such processing begins by buffering cells of each virtual circuit into a corresponding buffer. The processing then continues by obtaining priority information for each virtual circuit and obtaining logical buffer de-queuing information. The priority information, for example, may equate to priorities established via the varying levels of ATM services. The logical buffer de-queuing information corresponds to an access sequence for a plurality of logical ring buffers that are comprised of the buffers, or buffer identifiers. The processing then continues by generating the combined virtual circuit based on the logical buffer de-queuing information and the priority information.
