摘要： A node in a network running a link-state routing protocol identifies certain routing control messages and stores the identified messages in separate queues. The queues are weighted such that each message type is allotted a predetermined amount of processing overhead to optimize the message processing by a node. In one embodiment, the node processor processes the queued messages in accordance with the entries in a weighted round robin polling table. An upper limit of processing time can be specified for each visit to a particular message queue.
摘要翻译：运行链路状态路由协议的网络中的节点识别某些路由控制消息，并将识别的消息存储在单独的队列中。对队列进行加权，使得每个消息类型被分配预定量的处理开销以优化节点的消息处理。在一个实施例中，节点处理器根据加权轮询轮询表中的条目处理排队的消息。可以为每次访问特定消息队列指定处理时间的上限。

摘要： A network utilizing a link-state protocol includes a plurality of nodes with associated trunks that recover in a staggered manner. A first trunk associated with a first node is selected for recovery. After the first trunk is recovered, further trunks are selected such that N or less trunks recover at the same time until all trunks associated with the first node are selected for recovery. Node recovery is staggered at selected intervals to minimize or eliminate overload conditions. Staggered recovery in accordance with the present invention can reduce the likelihood of trunk loss due to excessive HELLO messages in an OSPF system and retransmission and retransmission lockout.
摘要翻译：利用链路状态协议的网络包括具有以交错方式恢复的相关干线的多个节点。选择与第一节点相关联的第一中继线进行恢复。在恢复第一个中继线之后，选择进一步的中继，使得N个或更少的中继线同时恢复，直到与第一个节点相关联的所有中继线被选择用于恢复。节点恢复以选定的间隔交错以最小化或消除过载条件。根据本发明的交错恢复可以减少由于OSPF系统中过多的HELLO消息而导致的中继线丢失的可能性，并且重传和重传锁定。

摘要： The present invention concerns a technique for providing Class-of-Service Routing in an ATM network (10) that utilizes the Private Network-Network Interface (PNNI) protocol. An originating node seeking to route a call to a terminating node does so by initially determining the class-of-service and then selecting a shortest length path there-between. Each successive link on the selected path is examined for sufficient available bandwidth and available depth (i.e., bandwidth not reserved for other services) for the Class-of-Service of the call. If every link possesses sufficient available bandwidth, then the call passes on the selected path. Otherwise, should a link on the selected path lack sufficient bandwidth and available depth, then a crankback message is sent to the originating node, and the originating node selects the next shortest path. Thereafter, the process of examining each link for sufficient bandwidth is repeated. If no path is found, the call is ultimately blocked.

摘要： A method for increasing the capability of the network to provide intelligent services can be accessed by any flow and allows the flow to install the services specific features to the flow. The present invention allows the software agents to be dynamically loaded into the network component to provide the services desired by the user. The present invention provides a detector in a switch in the network processing the flow that detects the presence of a predetermined control packet in the flow, and upon detection of this control packet, the detector loads a particular software object from a library of objects into the switch or router, which software object is then immediately executed by the switch to process the flow. This enables the user of the switch to request additional service from the switch after the data flow has been initiated, or to modify the flow parameters in a seamless manner.

摘要： The priority of the flow of packets representing calls or other connection requests within a packet network (10) is determined from the Class-of-Service of the call. Upon receipt of a call, a recipient router (121, 122, 123) identifies available paths, typically by exchanging messages with the other routers in the network. After selecting the path, the recipient router or centralized bandwidth broker determines whether the links comprising the selected path have available bandwidth for the class of service of the call. If so, the router routes the call to the next hop along the path. Otherwise, the router selects another path(s) and checks whether the links on the path possess sufficient bandwidth for the class of service of the call.
摘要翻译：在分组网络（10）中表示呼叫或其他连接请求的分组流的优先级是根据该呼叫的服务等级来确定的。在接收到呼叫时，接收者路由器（121,122,123）通常通过与网络中的其他路由器交换消息来识别可用路径。在选择路径之后，接收者路由器或集中带宽代理确定包括所选路径的链路是否具有用于该呼叫的服务类别的可用带宽。如果是这样，则路由器将该呼叫路由到沿路径的下一跳。否则，路由器选择另一路径，并检查路径上的链路是否具有用于呼叫服务类别的足够带宽。

摘要： An originating switch (110) in a packet-based telecommunications network (100) routes calls to a terminating switch using the combination of Success-to-the Top (STT) and Class-of-Service criterion. In routing a call to the terminating switch, the originating switch 110 checks for available bandwidth for the class of service of the call on the direct path (116) between switches. If the path has available bandwidth, the originating switch routes on the direct path. Otherwise, the originating switch searches for the most recently successful one of a plurality the via switches (1181-118n) linking the originating and terminating switches to determine whether that via switch can successfully route the call to the terminating switch. If the most recently successful one of the via switches possesses available bandwidth to route the call in accordance with its class of service, the originating switch 110 selects that via switch to route the call. Otherwise, if the most-recently successful via switch can not route the call, the originating switch 110 searches for a next successful via switch. If none of the via switches 1181-118n can successfully route the call in accordance with its class of service, the originating switch will either attempt a route advance or crankback the call.
