摘要： Various systems and methods are disclosed for performing multicast routing over unidirectional links. For example, one method involves maintaining a multicast adjacency state, which is associated with an interface that is coupled to receive messages from a network device via a unidirectional link. The multicast adjacency state identifies a network address of the network device. The method also involves sending a multicast protocol control message to the network device via a bidirectional path. The destination address of the network multicast protocol control message is the network address in the multicast adjacency state.

摘要： The invention provides a method and system for multicast group routing using unidirectional links. A set of uplink routers and a set of downlink routers provide a primary unidirectional distribution path from a set of sources to a set of destinations. A relatively smaller reverse communication channel is provided between the destinations and the sources. When a destination desires to add itself to, or take itself off, a multicast distribution group, one of the downlink routers acts as a proxy for that destination and so informs the relevant source. The selection of the proxy reporter for downlink routers or the querier for uplink routers does not require bi-directional communication between either of them, respectively.

摘要： The invention provides a method and system for multicast packet routing, in which only selected routers in a network subset (in a preferred embodiment, those routers on the border of the domain) maintain routing information external to the network subset, while all other routers in the network subset (non-border routers) maintain only information regarding routing within the network subset, including which border routers are on the path from the multicast source device or to the destination devices. The network subset is preferably a domain or other routing domain. A multicast distribution tree is maintained, using protocol messages which are transmitted from leaf nodes toward a root of the tree, while data packets to be multicast are distributed from the root toward the leaf nodes. In each network subset, such as a routing domain, each multicast packet is associated with a multicast distribution tree. The multicast distribution tree is associated with an upstream border router (UBR) and a set of downstream border routers (DBRs). The UBR and DBRs maintain complete routing information for each multicast source device, while all other routers in the network subset maintain routing information only to the UBR and DBRs. A "JOIN" or "PRUNE" protocol message associates a particular UBR with a particular multicast source device, so that non-border routers within the network subset only have to maintain routing information to border routers, while still being able to correctly maintain a multicast distribution tree rooted at a node outside the network subset.

摘要： A reliable transport protocol, suitable for routing protocols, that works with unicast transmission and multicast transmission, and an improved routing protocol based thereon. Multicast transmissions can be interspersed with unicast transmissions in situations where some of the receivers have received all of the packets sent to them and others have not. A mechanism to deliver multicast packets quickly to some receivers, even when there are unacknowledged packets pending for other receivers. When a packet is multicast from a sender node to all of its neighbors, the sender puts the packet on a queue for each neighbor and retransmits the packet if an acknowledgement has not been received within a predetermined period of time. If the packet is retransmitted, it is transmitted as a unicast. The invention takes advantage of the fact that the sender already has to maintain state information to determine who has not received its packets. A technique for distributing routing information gathered by a router outside an autonomous system of routers using the same routing protocol. A metric calculated by an identical routing protocol or a different routing protocol may be distributed and used by routers in a different autonomous system. Packets may be labeled with authentication information or with an administrative tag that specifies a method of routing in response to policy considerations.
摘要翻译：适用于基于单播传输和组播传输的路由协议的可靠传输协议，以及基于此的改进的路由协议。在某些接收机已经接收到发送给他们的所有数据包和其他数据包的情况下，组播传输可以穿插单播传输。即使在其他接收者有未确认的数据包待处理的情况下，也可以快速将某些接收器传送多播包的机制。当分组从发送方节点多播到其所有邻居时，发送方将分组放置在每个邻居的队列上，并且如果在预定时间段内尚未接收到确认，则重新发送分组。如果重传数据包，则将其作为单播传输。本发明利用了发送者已经必须维护状态信息以确定谁没有收到其分组的事实。一种用于分发路由信息的技术，路由信息由路由器在自治系统之外使用相同的路由协议收集。由相同的路由协议或不同的路由协议计算的度量可以由不同的自治系统中的路由器分发和使用。数据包可以用身份验证信息或者管理标签进行标记，该标签指定了响应策略注意事项的路由方法。

摘要： In one embodiment, an indication of a fault condition is received relating to a first service running on a physical device in a computer network. The first service is associated with a first virtual device context defined on the physical device. Then, the first service is disabled without affecting operation of a second service on the physical device. The second service is associated with a second virtual device context defined on the physical device. In another embodiment, a first virtual device context is created on a physical device in a computer network. Then, a second virtual device context is created on the physical device. The first virtual device context may then be managed independently of the second virtual device context such that resources assigned to a virtual device context are managed without affecting management of another virtual device context.

摘要： Various techniques for exchanging control messages in order to gracefully reroute multicast traffic are disclosed. For example, one method involves sending a join message for a multicast group towards a root of a new multicast tree and forwarding multicast traffic, addressed to the multicast group, on a current multicast tree until an acknowledgment corresponding to the join message is received. The new multicast tree can be identified in response to detection of a topology change within the network. Until the acknowledgment is received, multicast traffic that is received via the new multicast tree can be dropped.
