发明名称 METHOD AND APPARATUS FOR CHECKING ANYCAST GROUP CONFIGURATION IN COMMUNICATION NETWORK
摘要 <p>The present invention provides a method and apparatus for checking Anycast Group Configuration (AGC) in the communication network. The checking node sends a first Echo Request Message to the Anycast Group. A node of the Anycast Group generates a first Echo Response Message according to the received first Echo Request Message and sends it to the checking node. Subsequently, the checking node judges whether the AGC information in the first Echo Response Message matches the expected configuration information. If they match each other, the checking node selects the corresponding pedal router for each node of the Anycast Group. Afterward, pedal routers respectively send a second Echo Request Message to its corresponding node in the Anycast Group. The nodes in the Anycast Group respectively generate a second Echo Response Message according to the received second Echo Request Message and send it to the checking node. Lastly, the checking node checks the AGC according to the received second Echo Response Messages. The present invention can check the reachability of each node in the Anycast Group.</p>
