摘要： An exemplary gateway apparatus provides push-to-talk (PTT) communications between users in one network with users in another network where the networks utilize different communication protocols. It includes two protocol modules that interface with the two networks, respectively. The protocol modules are capable of receiving and transmitting messages compatible with the communication protocols used by the associated networks. An interoperability module, connected between the two modules, converts PTT control messages received from one of the networks into PTT control messages compatible with and transmitted to the other network. The PTT control messages received from the one network have a protocol that differs from the protocol of the PTT control messages transmitted to the other network.

摘要： A method and apparatus for configuring connectivity at a hub having a plurality of subscriber lines from a plurality of subscriber premises and a plurality of feeder lines from a central office. The hub provides connectivity between the plurality of subscriber premises and the central office. The method and apparatus include categorizing the plurality of subscriber lines into a plurality of groups based on penetration rates and churn rates of the plurality subscriber lines. Each group of subscriber lines are connected to feeder lines based on the penetration and churn rates for POTS and/or DSL services. Subscriber line groups with high penetration rates and high/low churn rates are coupled directly to feeder lines. Subscriber line groups with low penetration rates and high/low churn rates are terminated at the hub. Subscriber lines with an intermediate penetration rate are candidates for being connected to the feeder lines via an automatic switch.

摘要： Methods and systems for forwarding packets over Label Switched Paths (LSPs) in a Virtual Private Network (VPN) are implemented within a Layer-2 architecture. A system includes a number of multi-purpose nodes connected by a number of multi-protocol label switching (MPLS) LSP links. Each multi-purpose node contains at least one bridging module (BM) that runs an extension of a bridging protocol (BP) contained in the IEEE 802.1d standard. The BP is used to establish MPLS LSPs between the BMs. The BP then generates a spanning tree using a spanning tree program to establish an optimal number of active LSPs. The remaining LSPs are then set to “inactive” The BM de-allocates the resources assigned to inactive LSPs and makes the resources available to other active LSPs.
摘要翻译：用于在虚拟专用网（VPN）中的标签交换路径（LSP）上转发数据包的方法和系统在第二层架构中实现。一种系统包括通过多个多协议标签交换（MPLS）LSP链路连接的多个多用途节点。每个多用途节点包含运行IEEE 802.1d标准中包含的桥接协议（BP）的扩展的至少一个桥接模块（BM）。 BP用于在BM之间建立MPLS LSP。 BP然后使用生成树程序生成生成树，以建立最佳数量的活动LSP。剩余的LSP然后被设置为“不活动”BM去分配分配给非活动LSP的资源，并使资源可用于其他活动LSP。

摘要： In one embodiment, an automatically maintained, distributed source tree (DST) network has a plurality of fully connected internal nodes. One or more internal nodes may be connected to one or more external nodes. A first internal node synchronizes its link-state database with another internal node by sending and receiving respective Reduced Sequence Number Packet-Data-Units (PDUs) (RSNPs). An RSNP includes summary information for link-state packets (LSPs) (1) originated by the first internal node, (2) received by the first internal node from the other internal node, and (3) received from and/or originated by external nodes. If an internal link fails, then the corresponding end-nodes may recover and maintain automatic DST operation by entering either relay-mode or switch-mode operation. In relay-mode operation, an end-node tunnels packets to the other end-node via an intermediary node. In switch-mode operation, an intermediary node is selected to forward packets from one end-node to the other end-node.
摘要翻译：在一个实施例中，自动维护的分布式源树（DST）网络具有多个完全连接的内部节点。一个或多个内部节点可以连接到一个或多个外部节点。第一内部节点通过发送和接收相应的减少序列号分组数据单元（PDU）（RSNP）来将其链路状态数据库与另一内部节点同步。 RSNP包括由第一内部节点发起的链路状态分组（LSP）（1），（2）由第一内部节点从另一个内部节点接收的摘要信息，以及（3）从外部接收和/或发起的节点。如果内部链路发生故障，则相应的终端节点可以通过进入中继模式或切换模式操作来恢复和维护自动DST操作。在中继模式操作中，终端节点经由中间节点将分组隧道传送到另一终端节点。在交换模式操作中，选择中间节点将分组从一个终端节点转发到另一个终端节点。
