摘要： A method and a system for obtaining a Host Identity Tag (HIT) are disclosed. The method for obtaining an HIT includes: receiving an update message that carries a newly generated HIT; and obtaining the newly generated HIT from the update message. In the method and system for obtaining an HIT above, the latest HIT and the current IP address of the host are obtained from the update message directly, or a third-party server is used to obtain the latest HIT according to the mapping relationship between the new HIT and the old HIT. In this way, normal communication may be performed.

摘要： The present disclosure discloses a method and device for advertising routing information and a method and system for implementing packet routing. The method for advertising routing information includes a routing information advertising device that obtains its address information; the routing information advertising device adds the address information to routing information to advertise; and the routing information advertising device advertises the routing information that carries the address information. With the technical solution of the present disclosure, the number of routing tables in a backbone network may be greatly reduced. This minimizes the rise of router costs and effectively avoids slower route convergence. In addition, a router in the backbone network can dynamically obtain address information of a core router that advertises an aggregate prefix, such that it may be easier to implement registration, update and query the mapping between a more detailed address prefix and a border router.

摘要： A method and system for improving a quality of communication based on a label distribution protocol is provided. The method includes the following: When a local label switching router (LSR) finds out a change of a route at an upstream node in a multicast label switching path (LSP), it calculates and sets up a new optimized multicast LSP according to the label distribution protocol (LDP), and delays to send a withdraw request to the upstream node in the former multicast LSP. An interruption of the data stream in the multicast LSP reconstruction procedures can be avoided or reduced, so that the loss of data packets caused by the multicast LSP adjustment is reduced, and the quality of communication of the multicast is improved.
