摘要： According to one embodiment, the invention is directed to a facility for providing Asynchronous Transfer Mode (ATM) and Internet Protocol (IP) Quality of Service (QoS) features in a digital communication node. The facility includes a plurality of logical input ports, a plurality of logical output ports, ATM switching elements, IP routing elements and QoS elements. The switching and forwarding elements transfer ATM data cells and IP data packets from the logical input ports to the logical output ports. The QoS elements prioritize, schedule and flow control the transfer of data, based at least in part on ATM QoS features associated with the ATM data cells and on IP QoS features associated with the IP data packets.

摘要： A method of establishing calls between an ingress MPC (the calling party) and an egress MPC (the called party) in MPOA enabled ATM based networks. The call establishment method utilizes the call request SETUP, CONNECT and CONNECT_ACK messages in creating the shortcut VCC between ingress and egress MPCs. The calling party is adapted to send a READY_IND message in a reliable manner to the called party indicating that it is ready to receive frames over the shortcut VCC. The called party starts sending data over the shortcut VCC only when it knows that the calling party is ready. The called party knows the calling party is ready upon receipt of a READY_IND message or at least one data frame on the shortcut VCC. The calling party knows that the called party is ready to receive frames when it receives the CONNECT message. Since the READY_IND message sent by the calling party may get lost, the calling party is adapted to re-send the READY_IND message repeatedly until it is certain the called party has received it. The calling party utilizes a timer whereupon expiration, the READY_IND message is re-sent to the called party and the timer is restarted.
摘要翻译：在MPOA启用的基于ATM的网络中，在入口MPC（主叫方）和出口MPC（被叫方）之间建立呼叫的方法。呼叫建立方法利用呼叫请求SETUP，CONNECT和CONNECT_ACK消息在入口和出口MPC之间创建快捷方式VCC。呼叫方适于以可靠的方式向被叫方发送READY_IND消息，指示其准备好通过快捷方式VCC接收帧。被叫方开始通过快捷方式VCC发送数据，只有当主叫方已经准备好了。被叫方知道呼叫方在接收到READY_IND消息或快捷方式VCC上的至少一个数据帧时准备就绪。主叫方知道被叫方在接收到CONNECT消息时准备好接收帧。由于主叫方发送的READY_IND消息可能会丢失，所以主叫方重复发送READY_IND消息，直到确定被叫方已经收到它为止。主叫方利用一个定时器到期，READY_IND消息被重新发送到被叫方，重启定时器。
