[0049] see figure 1 , the first embodiment of the present invention provides a Hello message processing method, which is applied to the first node managed by the link management protocol LMP, including:

[0050]Step 101: Obtain the first control channel among multiple refreshable control channels with refresh function enabled between the first node and the second node managed by the LMP, where the first control channel is one of the multiple refreshable control channels The minimum control channel for sending period of Hello message.

[0051] Wherein, the refresh function allows to send the Hello message of the control channel through a specified control channel. Obtain the first control channel with the smallest sending period among the refreshable control channels with the refresh function enabled, so as to send the Hello message through the first control channel.

[0052] Step 102, according to the sending period of the first control channel, generate a Hello message for ...

[0073] see figure 2 , the second embodiment of the present invention provides a Hello message processing device, which is applied to the first node managed by the link management protocol LMP, including:

[0074] The acquiring module 201 is configured to acquire a first control channel among multiple refreshable control channels with refresh function enabled between the first node and the second node managed by the LMP, the first control channel is a plurality of refreshable control channels The minimum control channel for the sending period of the Hello message in the channel.

[0075] Wherein, the refresh function allows to send the Hello message of the control channel through a specified control channel. Obtain the first control channel with the smallest sending period among the refreshable control channels with the refresh function enabled, so as to send the Hello message through the first control channel.

[0092] The third embodiment of the present invention provides a Hello message processing method, which is applied to the second node managed by the link management protocol LMP, including:

[0093] When a Hello message for simultaneously refreshing multiple refreshable control channels is received, update the protocol state of the control channel corresponding to the channel ID carried in the Hello message for simultaneously refreshing multiple refreshable control channels on the second node .

[0094] Wherein, since the control channels between nodes are bidirectional, each control channel corresponds to a reverse control channel; when the second node receives the channel ID carried in the Hello message, it usually directly updates the corresponding channel ID with the channel ID. Corresponding to the protocol status of the reverse control channel, the protocol status of the reverse control channel also represents the protocol status of the original control channel.

Abstract

The invention provides a Hello message processing method and a Hello message processing device. The method is applied to a first node managed by a link management protocol (LMP), and comprises the steps of acquiring a plurality of first control channels in refreshable control channels of which refreshing functions are enabled between the first node and a second node managed by the LMP, wherein thefirst control channel is the control channel in the plurality of refreshable control channels with the minimum Hello message sending period; and generating Hello messages used for simultaneously refreshing the plurality of refreshable control channels according to the sending period of the first control channel, and sending the Hello messages to the second node via the first control channel. According to the method and the device provided by the invention, the problem that the number of Hello messages is increased due to increased number of the control channels, and thus network congestion occurs, and sending and receiving of service control messages are affected is solved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a Hello message processing method and device. Background technique [0002] In the current general multi-protocol label switching protocol (GMPLS, Generalized multi-protocol labelswitching) protocol family, the link management protocol (LMP, Link Management Protocol) is used to manage the link between nodes and the control channel (IPCC, IP Control Channel )manage. [0003] The functions of LMP include control channel management, link attribute association, link connectivity verification and fault management. Among them, the first two items are used to manage traffic engineering (TE, Traffic Engineering), which are the core functions necessary for the link; the last two items are optional extension functions, which are used to cope with the separation of the control channel and the data channel. [0004] Control channel management is used to determine and maintain the co...
