ARRANGEMENT FOR PACKET BASED CALL-RELATED HIGH AVAILABILITY SOLUTIONS

摘要

A kind of method,Method for exchanging vertical information hierarchical, redundant on-premise network. Airtight endpoint side, first message, such as user's registration message are sent, and vertically upwards from layer to layer. Respectively to node has been passed through, address list peer is added to message in current layer. When reaching uppermost layer, all address lists are added to message and are being stored in node, because of layer. Second message determines that first message is sending from the latter's node in opposite vertical direction from layer to layer, wherein the second message always includes the previously passed node and its redundancy peer-to-peer of address. These addresses are stored in each node and receive the message. Therefore, uppermost layer is vertically oriented to the bottom in the message transmission that terminal side will be appreciated by all substitution routings. Equally, for the message sent up, each node will be appreciated by the above-mentioned layer of address of node in all layers. Disclosed embodiment of this invention provides the short time, and radio resource is movable during the connection and limits the normal execution of processing expense, reduces redundancy.
