    • A virtual private network (VPN) service is provided through a shared network infrastructure comprising a plurality of interconnected provider edge (PE) devices having customer edge (CE) interfaces. Some of the CE interfaces are allocated to a VPN supporting a plurality of virtual local area networks (VLANs) and are arranged for exchanging traffic data units with CE devices. Each traffic data unit includes a VLAN identifier. At least one virtual connection is established in the shared network infrastructure between two CE interfaces of different PE devices, allocated to said VPN, for forwarding traffic data units including a VLAN identifier. Said virtual connection (VC) has an identifier determined from said VLAN identifier and an identifier of said VPN.
    • 通过共享网络基础设施提供虚拟专用网(VPN)服务,该共享网络基础设施包括具有客户边缘(CE)接口的多个互连的提供商边缘(PE)设备。 一些CE接口被分配给支持多个虚拟局域网(VLAN)的VPN,并被安排用于与CE设备交换业务数据单元。 每个流量数据单元包括VLAN标识符。 在分配给所述VPN的不同PE设备的两个CE接口之间的共享网络基础设施中建立至少一个虚拟连接,用于转发包括VLAN标识符的业务数据单元。 所述虚拟连接(VC)具有从所述VLAN标识符确定的标识符和所述VPN的标识符。

    • A method and system for determining the best data path in a communication network is presented. A Least Cost Routing path between end users in a multi-network environment, including both public and private networks, is determined based upon a longest prefix match. At network activation time, the numbers or prefixes of numbers of end users attached to the public network (304, 305) are stored in entry node data bases A and C of the private network (303). Assuming an end user terminal U1 calls a target end user U3, an entry node B first checks for a longest prefix match between the called number and numbers already stored into its memory. If this is the first time U3 is called via node B, no match will occur and node B will then broadcast a Query to all nodes in the private network (i.e. Nodes A and C). Only those nodes providing possible access to U3 answer this Query. Node B then determines the longest prefix match with the called number amongst the various query answers, and sets the data path via that node having the longest prefix match.
    • 提出了一种用于确定通信网络中最佳数据路径的方法和系统。 基于最长的前缀匹配来确定多网络环境中的最终用户(包括公共和专用网络)之间的最小成本路由路径。 在网络激活时,附加到公共网络(304,305)的最终用户的号码的数量或前缀被存储在专用网络(303)的入口节点数据库A和C中。 假设终端用户终端U1调用目标终端用户U3,入口节点B首先检查被叫号码和已存储到其存储器中的号码之间的最长前缀匹配。 如果这是通过节点B第一次调用U3,则不会发生匹配,并且节点B然后将向专用网络(即,节点A和C)中的所有节点广播查询。 只有提供可能访问U3的那些节点才能回答此查询。 然后,节点B确定在各种查询答案中与被叫号码的最长前缀匹配,并且经由具有最长前缀匹配的节点来设置数据路径。
