摘要： Congestion in a high speed connection oriented packet network carrying bursty data and real time service is avoided by a novel in-call negotiation scheme for reserving bandwidth for real time calls and reserving buffer capacity for bursty calls.For a real time call, a centralized call controller in each switch in the network determines which of its outgoing trunks has available to it the peak bandwidth needed to accommodate the call. Once one of these trunks is found, the call routing is set up so that the call is directed through that trunk and the peak bandwidth requirement of the call is allocated on that output trunk for the duration of the call.The network contains one or more switches, each of which has a centralized call controller and a plurality of trunk controllers. The call controller routes calls from a plurality of input trunks to a plurality of output trunks, identifies kinds of calls, and allocates bandwidth on the output trunks. The trunk controllers perform in-call buffer reservation independent of the routing, identification, and bandwidth allocation performed by the call controller. This relieves the call controller of the extra burden of performing buffer reservation and it permits buffer reservation to be accomplished in a shorter period of time.
摘要翻译：通过一种用于为实时呼叫预留带宽和为突发呼叫预留缓冲器容量的新颖的呼叫协商方案，避免了承载突发数据和实时业务的高速连接定向分组网络中的拥塞。对于实时呼叫，网络中每个交换机中的集中式呼叫控制器确定其出站中继线可用于其适应呼叫所需的峰值带宽。一旦找到这些中继线之一，则建立呼叫路由，使得呼叫被引导通过该中继线，并且呼叫的峰值带宽需求在该呼叫的持续时间内被分配在该输出中继线上。网络包含一个或多个交换机，每个交换机具有集中呼叫控制器和多个中继控制器。呼叫控制器将来自多个输入中继线的呼叫路由到多个输出中继线，识别呼叫类型，并在输出中继线上分配带宽。中继控制器执行呼叫缓冲区预留，独立于由呼叫控制器执行的路由，标识和带宽分配。这减轻了呼叫控制器执行缓冲区预留的额外负担，并允许呼叫控制器在更短的时间内完成缓冲区预留。

摘要： A facility is provided for use in a packet switch to control unnecessary multiple retransmissions of a data packet. In an exemplary embodiment of the invention, such control is achieved by tracking in a list the sequence numbers of transmitted data packets and retransmitting a data packet only if its sequence number appears in the list prior to the sequence number of the last data packet that is received correctly by a receiver. The sequence number associated with a retransmitted data packet is deleted from the list and then appended to the list to place the number in proper relationship with the sequence numbers of data packets transmitted after the initial transmission of the retransmitted data packet.

摘要： The retransmission of signaling messages that data terminals (e.g., modems) might exchange prior to exchanging user data is controlled by arranging a data terminal that receives multiple copies of the same signaling message so that it saves only the first copy thereof, but transmits a response to the sending terminal following receipt of each such copy. The sending terminal terminates its transmission of the signaling message upon receipt of a response from the receiving terminal. The inventive procedure is especially advantageous for controlling the retransmission of signaling messages during a n-way handshake between two terminals.
摘要翻译：数据终端（例如，调制解调器）在交换用户数据之前可能进行交换的信令消息的重传是通过布置接收相同信令消息的多个副本的数据终端来进行控制的，使得它只保存其第一副本，但是发送响应在收到每份此类副本后，发送终端。发送终端在接收到来自接收终端的响应时终止信令消息的传输。本发明的过程对于在两个终端之间的n次握手期间控制信令消息的重传是特别有利的。

摘要： Multiple requests to set up and/or tear down connections in a node of a communication network (or multiple failure notifications) are bundled together for transmission within the network. In an “inter-nodal” embodiment, multiple connection requests/failure notifications are bundled together as a single message for transmission between pairs of nodes in the network. In an “intra-nodal” embodiment, multiple connection requests/failure notifications received at one component of a node in the network are bundled together as a single group for forwarding to another component within the same node for implementation. In either case, the bundling of multiple connection requests/failure notifications can reduce the total amount of time required to communicate and implement the desired connection requests/restoration processing. This reduction in time can be critical to the ability of a network to satisfy requirements associated with restoration processing following a network fault.
摘要翻译：在通信网络的节点（或多个故障通知）中建立和/或拆除连接的多个请求被捆绑在一起以在网络内传输。在“节点间”实施例中，将多个连接请求/故障通知捆绑在一起作为单个消息以在网络中的节点对之间进行传输。在“节点内”实施例中，在网络中的节点的一个组件处接收的多个连接请求/故障通知被捆绑在一起作为单个组，用于转发到同一节点内的另一个组件以用于实现。在任一情况下，多个连接请求/故障通知的捆绑可以减少通信和实现所需的连接请求/恢复处理所需的总时间量。网络故障后，网络能够满足与恢复处理相关的要求，这种时间的减少对于能力至关重要。

摘要： A communication device includes a transmitter portion, a receiver portion and a management portion. The transmitter portion transmits information into a channel. The receiver portion receives information from the channel. The management portion includes a request-to-send packet generating portion, a clear-to-send packet receiving portion, a threshold database, a comparator and a resolution packet generating portion. The threshold database stores a threshold value for the parameter of the channel and provides the threshold value to the comparator. The comparator compares the threshold value and the channel parameter information and generates an instruction signal based on the comparison. The resolution packet generating portion generates a resolution packet based on the instruction signal and provides the resolution packet to the transmitter portion.

摘要： A method for representing, in a network data structure, a minimum amount of protection bandwidth required to be reserved on each link in a mesh network, to restore service upon failure of another node or link in the network. The method includes (1) receiving a request for a new service in the network, wherein the new service is represented by a service data structure having an identification of each link and transit node in a primary path for the new service, (2) determining, using the network and service data structures, whether the new service requires additional protection bandwidth to be reserved on any link in the network, and (3) updating the network data structure if any additional protection bandwidth is determined to be needed. In one implementation the network and service data structures are vectors and the steps of determining and updating involve vector operations between these structures.
