Embodiment Construction

[0026] In the embodiment of the present invention, when the PIM-DM Hello message is generated, it is judged whether the aging time set is greater than the maximum value of the aging time, if yes, the aging time of the PIM-DM Hello message is set to the maximum value; otherwise , keep the set aging time.

[0027] Since the aging time of the PIM-DM Hello message does not exist in isolation, but is proportional to the sending interval of the PIM-DM Hello message, the ratio between the sending time interval and the aging time mentioned here can also be preset.

[0028] The main realization principles, specific implementation modes and corresponding beneficial effects that can be achieved of the technical solutions of the embodiments of the present invention will be described in detail below in conjunction with each accompanying drawing.

[0029] Such as figure 2 , which is the format of the PIM-DM Hello packet. in,

[0030] Version: For PIM-DM, the version is 2.

Abstract

The invention discloses a Hello message generation method and a device thereof. When aging time of the Hello message is confirmed larger than maximum aging time, the aging time of the Hello message is set as the maximum aging time and the Hello message is generated according to the set aging time of the Hello message. The embodiment of the invention can prevent aging time of the Hello message sent by a PIM-DM route from overflowing. The proposal provided by the embodiment of the invention can prevent a neighbor from being deleted when PIM-DM Hello sending time interval is over large and avoid interruption of multicast data stream and normal service caused therefrom.

Description

technical field [0001] The invention relates to the technical field of computers and communications, in particular to a method and device for generating a Hello message. Background technique [0002] The Internet Engineering Task Force (IETF, The Internet Engineering Task Force) is a loose, self-disciplined, voluntary non-governmental academic organization established at the end of 1985. Its main task is to be responsible for the development and formulation of Internet-related technical specifications. Request For Comments (RFC, Request For Comments) is a formal document formulated by the IETF for unlimited distribution. Each RFC document has a unique number to identify. [0003] A router is a network device that connects multiple networks or network segments and has routing functions. Routing is the act of transferring packets from the data source across the network to the destination according to the IP address. Routing can be divided into unicast routing and multicast ...
