Abstract: Provided are a method and device for sending message. The method includes that: a mapping table is established; a message is received from a receiver; the mapping table is searched to obtain a Route Identification (RID) of an Access Service Node (ASN) of a sender corresponding to the message according to the message; and the message is sent to the ASN according to the found RID of the ASN. By the technical solution, the problem of non-uniformity of access manners for uplink and downlink data streams in a related technology is solved, and a proper access manner can be selected for the downlink data stream.

Abstract: A mobile node mapping information update triggering method, information reporting method, mapping server and mobile node, applied to a Locator/Identifier Separation Protocol (LISP) network, wherein the mobile node mapping information update triggering method comprises: a mapping server (MS) receiving a mapping registration message for updating mapping information transmitted by a MN attached to the MS; the MS acquiring the information of a communication peer, and according to the information of the communication peer, transmitting a mapping update message to a peer mapping cache device corresponding to the communication peer of the MN, thus triggering the peer mapping cache device to update the cached mapping information. In the abovementioned solution, it overcomes the problem that the mobile node has to bear a large amount of signaling overheads in order to update the peer cache.
