摘要： A service provider's routers (PE1, P1, P2, PE2) provide connections between and share routine information with routers (CE1, CE2) of a customer virtual private network (VPN) as well as routers of other customers' VPNs, which may have overlapping address spaces. A service provider's edge router (PE1) informed by the customer's router (CE1) that it will forward packets to a given prefix notifies the other edge router (PE2) that PE1 can forward packets to that address prefix if the destination is in the VPN to which CE1 belongs. PE1 also tells PE2 to tag any thus-destined packets with a particular tag T3. PE2 stores this information in a forwarding information base that it separately keeps for that VPN so that when PE2 receives from a router CE2 in the same VPN a packet whose destination address has that prefix, it tags the packet as requested. But PE2 also tags it with a tag T2 that the router P2 to which PE2 first sends it has asked PE2 to apply to packets to be sent to PE1. P2 routes the packet in accordance with T2, sending it to P1 after replacing T2 with a tag T1 that P1 has similarly asked P2 to use. P1 removes T1 from the packet and forwards it in accordance with T1 to PE1, which in turn removes T3 from the packet and forwards it in accordance with T3 to CE1. In this manner, only the edge routers need to maintain separate routing information for separate VPNs.

摘要： A tag-switching router on a tag-switching network properly generates and forwards an ICMP message when an input packet containing a faulty tagged IP datagram is received. The faulty IP datagram includes source and destination IP addresses and is prepended with a tag stack containing a top tag entry having a top tag. Using the top tag to point to an entry in a forwarding table, the tag-switching router retrieves both a replacement tag and the identity of a forwarding link, and replaces the top tag in the tag stack with the replacement tag. The tag-switching router prepends the tag stack containing the replacement tag to an output IP datagram, which contains the ICMP message and also includes the faulty IP datagram's source IP address as its destination IP address, and discards the faulty IP datagram. The tag-switching router forwards the output IP datagram in an output packet over the forwarding link so that the ICMP message continues over the route that was originally specified for the faulty IP datagram. When the ICMP message finally leaves the tag domain, i.e., when it reaches a router that does not perform tag switching, it is turned around and sent back onto the tag-switching network and, in accordance with the destination IP address of the output IP datagram, back over the original route to the source of the faulty IP datagram.
摘要翻译：当接收到包含有故障标记的IP数据报的输入分组时，标签交换网络上的标签交换路由器正确地生成并转发ICMP消息。错误的IP数据报包括源IP地址和目标IP地址，前缀包含一个标签堆栈，其中包含顶层标签条目。使用顶部标签指向转发表中的条目，标签交换路由器检索替换标签和转发链路的标识，并用替换标签替换标签堆栈中的顶部标签。标签交换路由器将包含替换标签的标签栈添加到包含ICMP消息的输出IP数据报，并将错误的IP数据报的源IP地址作为其目标IP地址，并丢弃有缺陷的IP数据报。标签交换路由器通过转发链路转发输出数据包中的输出IP数据报，以便ICMP消息在最初为故障IP数据报指定的路由上继续。当ICMP消息最终离开标签域时，即当到达不进行标签交换的路由器时，它被转回并发回到标签交换网络，并且根据输出IP的目的地IP地址数据报，将原始路由返回到故障IP数据报的源。

摘要： In one embodiment, a device of a particular non-backbone routing domain in a computer network determines whether each of one or more routes is reachable within the particular non-backbone domain. The device may then generate a filtered set of label mappings having only those of the one or more routes reachable within the particular non-backbone domain. Accordingly, the device may advertise label mappings only of the filtered set to one or more neighboring devices.

摘要： A system and method for minimizing latency for direct group communications, such as push-to-talk (PTT) calls, among a group of wireless telecommunication devices on a wireless telecommunication network. The wireless telecommunication device has a dormant state without an open dedicated traffic channel for communications therefrom and an active state in which the wireless devices opens a dedicated traffic channel for an outgoing communication from the wireless telecommunication device, to include a direct communication stream. Either the wireless telecommunication device or an intermittent communication server for group communication streams can buffer the initial communication data of a group communication stream while the sending and/or receiving wireless telecommunication device changes from a dormant state to an active state with an open dedicated traffic channel.

摘要： A system and method for providing high performance dispatch services for a push-to-talk (PTT) communication over a wireless communication network. When a wireless device is powered up, it registers with a server and then transitions to a paging state instead of an idle state. When the wireless device is ready to transmit PTT communications, it sends a message to the server and transitions to a transmission state when a confirmation is received from the server. Once in the transmission state, the wireless device is ready to transmit the PTT communications to the server.

摘要： A technique maintains Interior Gateway Protocol (IGP) transparency of Virtual Private Network (VPN) routes when Border Gateway Protocol (BGP) is used as a Provider Edge Device (PE) to Customer Edge Device (CE) protocol in a computer network. According to the novel technique, a first CE generates a BGP advertisement to advertise one or more VPN routes of its customer network, the BGP advertisement having one or more transitive IGP attributes for the advertised routes. The first CE sends the BGP advertisement to a first PE, which then propagates the BGP advertisement among devices of a provider network maintaining the transitive IGP attributes. A second PE sends the BGP advertisement to a second CE, along with the transitive IGP attributes. Upon receiving the BGP advertisement, the second CE converts the BGP advertisement and transitive IGP attributes into corresponding IGP advertisements. The second CE may then propagate the IGP advertisements into its customer network as either internal VPN routes or as external routes accordingly.

摘要： A system and method for signaling and delivering group communication data, such as push-to-talk (PTT) setup data, to a dormant wireless telecommunication device across a control channel on a wireless communication network. Each wireless telecommunication device is able to direct a single group communication stream to a designated target group of other wireless telecommunication devices, and the wireless telecommunication device has a dormant state in which the wireless telecommunication devices bridges a control channel with a communication server and an active state in which the wireless telecommunication device bridges a dedicated communication channel with the communication server. The wireless telecommunication device receives group communication setup data though a control channel for incoming group communications, and such delivery occurring without fully bridging a dedicated communication channel to that wireless telecommunication device.

摘要： In group wireless telecommunication, such as push-to-talk (PTT) calls, a voice communication is broadcast through Internet protocol data packets to other member devices of the PTT group. At least one communication server receives a single communication stream from a communicating wireless device, such as a PTT call, and creates a group communication to all wireless telecommunication devices of the designated group with the broadcast of Internet protocol data packets containing the voice data of the communication stream to one or more wireless telecommunication devices of the receiving group that can receive and handle the packets. Other wireless network infrastructure can be used to assist the communication server in generation and broadcast of the Internet protocol data packets to the receiving wireless telecommunication devices.

摘要： A method and apparatus for adding a member to an active call in a group communication network provides for receiving a member list from a user and sending a request to a server to add the member list to the active group call. The method and apparatus further provides for announcing each member in the member list that they are being added to the group call, receiving acknowledgement from a member who wishes to participate in the group call, and forwarding media to the member. The method and apparatus also provides for a significant reduction in the actual total dormancy wakeup time and latency by exchanging group call signaling even when mobiles are dormant and no traffic channel is active.
