METHOD FOR DETECTING MESSAGE LOOP, ROUTING AGENT APPARATUS AND NETWORKING SYSTEM
First Claim
1. A method for detecting a message loop, the method comprising:
- receiving a request message sent by a network element apparatus;
acquiring routing information for sending the request message to a server apparatus;
detecting whether a next-hop link for sending the request message and a link for receiving the request message belong to a same link set, wherein the next-hop link is included in the routing information; and
sending a response to the network element apparatus indicating that a message loop is detected, when it is detected that the next-hop link for sending the request message in the routing information and the link for receiving the request message belong to the same link set.

Abstract
A method for detecting a message loop, a routing agent apparatus, and a networking system. The method for detecting a message loop includes: receiving a request message sent by a network element apparatus; acquiring routing information for sending the request message to a server apparatus; detecting whether a next-hop link for sending the request message in the routing information and a link for receiving the request message belong to a same link set; and sending a response to the network element apparatus that a message loop is detected, when it is detected that the link for sending the request message in the routing information and the link for receiving the request message belong to a same link set. The technical solutions disclosed herein can improve the efficiency of detecting the message loop and thus have strong practicability.

8. A routing agent apparatus, comprising:
-
a receiving module, configured to receive a request message sent by a network element apparatus; an acquiring module, configured to acquire routing information for sending the request message to a server apparatus; a detecting module, configured to detect whether a next-hop link for sending the request message in the routing information and a link for receiving the request message belong to a same link set; and a sending module, configured to send a response to the network element apparatus indicating a message loop is detected, when it is detected that the link for sending the request message in the routing information and the link for receiving the request message belong to the same link set. - View Dependent Claims (9, 10, 11, 12, 13)

14. A networking system, comprising:
-
a network element apparatus; and a routing agent apparatus, wherein the network element apparatus is configured to send a request message to the routing agent apparatus; wherein the routing agent apparatus is configured to; receive the request message sent by the network element apparatus and acquire routing information for sending the request message to a server apparatus; detect whether a next-hop link for sending the request message in the routing information and a link for receiving the request message belong to a same link set; and send a response indicating a message loop is detected to the network element apparatus, when it is detected that the link for sending the request message in the routing information and the link for receiving the request message belong to the same link set. - View Dependent Claims (15, 16, 17)
