Similar to MIPv4, it frequently and periodically multicasts / broadcasts router announcement messages to user terminals under its jurisdiction, and the multicast / broadcast domain is very large, with multi-level switches and DSLAMs in the middle, and edge routers frequently broadcast / broadcast Multicasting these messages will cause the spread of these messages in the Metropolitan Area Network (EMAN, Ethernet-based Metropolitan Access Network). In MIPv6, when using the minimum interval and delay, the unsolicited multicast router announcement message The average interval time is 50ms, therefore, a lot of bandwidth resources of the network are wasted, and the transmission quality of other services transmitted on the MAN is reduced
At the same time, controlling the sending of these proxy request messages will also occupy the CPU of the edge router

[0062] i) DSLAM2a initially does not contain any AA message, and then, DSLAM2a is initially configured with AA message. The steps of this configuration can be manually configured, for example, the network management configures the AA message in the edge router 3a and the DSLAM2a at the same time, or DSLAM2a can obtain the AA message sent from the edge router 3a. At this time, in step S11, DSLAM2a immediately judges Satisfy the first predetermined condition.
[0063] ii) The AA message from the edge router 3a (hereinafter referred to as the pre-stored AA message) is pre-stored in the DSLAM2a, and the DSLAM2a receives the AA message from the edge router 3a (hereinafter referred to as the current AA message). At this time, DSLAM2a detects whether the current AA message received is the same as the pre-stored AA message stored in DSLAM2a, if the current AA message is different from the pre-stored AA message, then in step S11, DSLAM2a judges that the first predetermined condition is...

A method for secondary controlling a mobile agent advertisement message in a network apparatus of a communication network includes the steps: one or more mobile agents advertisement messages are obtained from one or more upper level network management apparatuses of the network apparatus; when the first preset condition is met, the mobile agent advertisement information corresponding to at least one message in one or more mobile agent advertisement messages is provided to one or more mobile nodes within the dominating area of the network apparatus; and when the second preset condition is met, one or more mobile agent advertisement request messages are controlled by the network apparatus to be transmitted to the upper layer network management apparatus so as to request the mobile agent advertisement message. A controlling device uses the method.
Description
technical field [0001] The invention relates to a communication network, in particular to a method and a device for auxiliary control of mobile agent announcement messages in the communication network. Background technique [0002] With the further deepening of fixed network and mobile network integration, mobile IP will be deployed in IP network. Mobile IPv4 (MIPv4) is a wireless extension to the existing IPv4 network. In MIPv4, an agent discovery mechanism is defined, which can be used for a mobile node (MN, Mobile Node) to detect its movement and determine the foreign agent care-of address provided by the foreign agent (FA, Foreign Agent) on the link it moves to (FACoA, Foreign Agent Care-of-Address), in order to complete the necessary business switching. [0003] A mobile node can discover that the subnet to which the mobile node is connected has changed through the link layer mechanism. Specifically, the base station of DSLAM or Wifi will broadcast the MAC frame of l...
