Abstract:
A telecommunications switch comprising:a first output port mechanism through which sessions having cells are sent at a total session rate to a network; a first input port mechanism through which sessions are received from the network, said first input port mechanism connected to the first output port mechanism, said first input port mechanism having a first guaranteed session rate; a second input port mechanism through which sessions are received from the network, said second input port mechanism connected to the first output port mechanism, said second input port mechanism having a second guaranteed session rate, the sum of all guaranteed session rates less than or equal to the total session rate; a first scheduler connected to the first and second input port mechanisms and to the first output port mechanism for scheduling sessions of the input port mechanisms for service; a server for providing service to sessions of the input port mechanisms, said server connected to the first and second input port mechanisms and the first output port mechanism; and a flow control mechanism for ensuring cells are not lost after they are received at an input port mechanism and until they are sent out an output port mechanism, said flow control mechanism connected to the input port mechanisms and the output port mechanism, said flow control mechanism adaptable to changes in input port mechanisms and output port mechanisms.
