摘要： A method for protecting the head node of a Point to Multipoint Label Switched Path (P2MP LSP) includes: a Backup Head Node (BHN) establishes a backup LSP from the BHN to all Merge Points (MPs), where the backup LSP bypasses a Master Head Node (MHN); the MHN forwards data along an LSP already established between the MHN and the MPs; when a head node switchover condition is met, the BHN is switched to a master mode to forward data along the backup LSP established between the BHN and the MPs. A system and apparatus for protecting the head node are also provided. With the head node protection solution provided by the present disclosure, the head node is well protected and the protection mechanisms for the P2MP LSP are therefore more complete. This can further promote the scale deployment of P2MP systems.

摘要： The present invention provides a method and an apparatus for abstracting logical topology information of a Peer-to-Peer (P2P) network. The method includes: obtaining a set of Points of Presence (POPs) of peer clients in the P2P network; using a relevant algorithm of a routing protocol to calculate a best path between any two POPs in the set of POPs and a weight value of the best path; and collecting calculation results of the best path and the weight value that are obtained on each POP to obtain a set of abstract logical topology records of the P2P network. The embodiments of the present invention provide a universal and efficient method for abstracting logical topology information, which greatly reduces network topology information that needs to be transmitted, mitigates a risk of exposing lower-layer network topology information, and transmits the network topology information to a P2P application server securely and concisely.
