摘要： A method for operating a node in a computer network is disclosed, where the network is made up of nodes connected by links. The method has the steps: determining an alternate path for one or more links; reserving resources for the alternate path; and rerouting traffic on the alternate path in case of a link failure. The alternate path may be periodically updated. A plurality of alternate paths may be maintained. The alternate paths may not have any links in common. User traffic may be rerouted substantially simultaneously to each link of the alternate path in the event of failure of a primary path.

摘要： In high speed cell switching networks, a Call Admission Control (CAC) procedure is performed on each connection according to a specified Traffic Descriptor. A mandatory parameter of the Traffic Descriptor is the Peak Cell Rate (PCR), associated with a Cell Delay Variation Tolerance (CDVT). Connections which specify a high CDVT value may potentially send into the network bursts of cells at a rate much higher than the declared Peak Cell Rate, which may lead to congestion in cell buffers of intermediate network nodes. Guaranteeing the Quality of Service (QoS) for such connections may require the reservation of a high amount of resources in the network, leading to poor utilization of those resources. A Call Admission Control procedure, associated with an Usage Parameter Control/Network Parameter Control mechanism, provides:accepting not bursty connections and guaranteeing the Quality of Service requested at connection setup,accepting very bursty connections and guaranteeing a minimal Quality of Service rather than simply rejecting them,protecting the network from potentially too bursty traffic,determining a bandwidth reservation method based on a Mean Burst Length,for every connection, minimizing the bandwidth reservation while satisfying the required Quality of Service.
摘要翻译： 在高速小区交换网络中，根据指定的业务描述符，在每个连接上执行呼叫接纳控制（CAC）过程。 流量描述符的强制参数是峰值信元速率（PCR），与信元延迟变化容差（CDVT）相关联。 指定高CDVT值的连接可能潜在地以比所声明的峰值信元速率高得多的速率发送到信元的网络脉冲串，这可能导致中间网络节点的信元缓冲器中的拥塞。 确保这种连接的服务质量（QoS）可能需要在网络中预留大量的资源，导致这些资源的利用率较低。 与使用参数控制/网络参数控制机制相关联的呼叫接纳控制程序提供：不接受突发连接并保证在连接建立时所请求的服务质量，接受非常突发的连接并保证最低服务质量，而不是简单地拒绝 他们，保护网络免受潜在的突发性流量，为每个连接确定基于平均突发长度的带宽预留方法，使带宽预留最小化，同时满足所需的服务质量。

摘要： A method and system of transmitting data frames from a sending unit (10) to a receiving unit (12) in a data transmission network comprising at least a backbone (14) wherein the data are transmitted over high speed links enabling long Maximum Transmission Units (MTU) between an ingress node (18) connected to the sending unit by a first access link (16) and an egress node (22) connected to the receiving node by a second access link (20), with at least one of the first and second access links being a low speed access link requiring the data frames to be segmented into short MTUs between the sending unit and the ingress node and between the egress node and the receiving unit.

摘要： A method and a system of network capacity planning for use in a high speed packet switching network. The network comprises a plurality of switching nodes interconnected through a plurality of communication links, each of the switching nodes comprises means for switching packets from at least one input link to at least one output link. Each of the output links is coupled to at least one buffer in the switching node for queuing packets before they are transmitted over the output link. In each of the switching nodes and for each of the output links, a time distribution of the occupancy of each buffer during a predetermined monitoring time period is measured, and stored in a centralized memory location. Then, the buffer occupancy time distribution data are retrieved from the centralized memory location in all the switching nodes, gathered and stored in a network dedicated server. These buffer occupancy time distribution data for all the nodes are transmitted from the dedicated network server to a network monitoring center. In the network monitoring center, the buffer occupancy time distribution data are integrated on a larger time scale, and stored. Finally, the integrated buffer occupancy time distribution data are used to apply network capacity planning actions to the network resources.
