Abstract:
1. A method for injecting a control cell into an established Asynchronous Transfer Mode (ATM) data connection between a source device and a destination device, wherein said control cell is injected into said connection by a control point of an infection switching node, said method comprising: generating a control cell composed of a payload and an ATM header containing an input Virtual Path/Virtual Circuit of said connection in order to constitute an ATM cell; encoding a switch routing label (SRL) and a protocol engine correlator (PEC) within said control cell; setting an injection flag within said control cell for indicating to an input protocol engine of said control point that said control cell is to be injected into said connection, said input protocol engine identifying incoming cells by performing a label lookup; reading said injection flag within said protocol engine; and bypassing said label lookup in view of said injection flag.
