Embodiment

The embodiment of the present invention provides a kind of collocation method of RRPP ring group, be applied to comprise in the RRPP network of Edge node and assistant edge node, by carry out the mutual of information between Edge node and assistant edge node, to complete the deletion of subring in the interpolation of subring in RRPP ring group or RRPP ring group.Collocation method flow process below in conjunction with the RRPP ring group shown in Fig. 2-Fig. 5 is elaborated to this process.

As shown in Figure 2, when when fringe node (Edge-node) above adds the subring of RRPP ring group, as: in the interior interpolation subring 4 of RRPP ring group 1 of fringe node, and RRPP ring group 1 has comprised subring 1, subring 2 and subring 3, the collocation method of the RRPP ring group that the embodiment of the present invention proposes comprises the following steps:

Step 201, fringe node adds subring to RRPP ring group.For example, fringe node adds subring 4 to RRPP ring group 1, and now RRPP ring group 1 comprises subring 1, subring 2, subring 3 and subring 4.

Step 202, fringe node sends the first message to assistant edge node, and carries the information of RRPP ring group and the information of subring in this first message.For example, in this first message, carrying the RRPP ring group that need to add to is RRPP ring group 1, and the subring that need to add RRPP ring group 1 to is subring 4.

In a kind of specific implementation, the first message can be for adding ring group membership message, and in this interpolation ring group membership message, carry the information of RRPP ring group and the information of subring, and this interpolation ring group membership message is used for notifying assistant edge node to add subring (being the information of subring) to RRPP ring group (being the information of RRPP ring group).For example, the type of message of this interpolation ring group membership message can be predefined type, as AddRgroupMember.

Step 203, assistant edge node, after receiving the first message, utilizes the information of RRPP ring group and the information of subring of in the first message, carrying subring to be added to RRPP ring group on assistant edge node.For example, assistant edge node is after receiving the first message, owing to carrying the RRPP ring group that need to add in the first message, it is RRPP ring group 1, the subring that need to add RRPP ring group 1 to is subring 4, add subring 4 to RRPP ring group 1, now RRPP ring group 1 comprises subring 1, subring 2 and subring 3, subring 4.

In prior art, when subring quantity is more in RRPP ring group, can cause greater impact to equipment performance.For example, user configures RRPP ring group on assistant edge node, has 64 subrings in this RRPP ring group; User configures before this RRPP ring group on fringe node, fringe node still sends Edge-Hello message for each subring to assistant edge node, owing to having enabled RRPP ring group on assistant edge node, therefore assistant edge node is after receiving the Edge-Hello message of subring 1, this Edge-Hello message is distributed to respectively in 64 subrings, by that analogy, assistant edge node, after receiving the Edge-Hello message of subring 64, is distributed to this Edge-Hello message respectively in 64 subrings.Further, if on fringe node for 2 Edge-Hello messages of each subring transmission per second, assistant edge node is per second need to distribute 64*2*64 Edge-Hello message, thereby equipment performance is caused to greater impact.

Further, based on above-mentioned discovery, when above configuring RRPP ring group at fringe node (Edge-node), and while adding the subring of RRPP ring group on fringe node, as: on fringe node, configure RRPP ring group 1, and in the interior interpolation subring 1 of this RRPP ring group 1, subring 2 and the subring 3 of fringe node, the collocation method of the RRPP ring group that embodiment of the present invention proposes comprises the following steps:

Steps A, fringe node configuration RRPP ring group, adds subring to RRPP ring group, selects a subring as the transmission subring of RRPP ring group the subring in RRPP ring group, and it is current in operating state not that RRPP ring group is set.For example, fringe node configuration RRPP ring group 1, adds subring 1, subring 2 and subring 3 to RRPP ring group 1, selects subring 1 as the transmission subring of RRPP ring group 1 subring in RRPP ring group 1, and it is current in operating state not that RRPP ring group 1 is set.

In the embodiment of the present invention, RRPP ring group on fringe node is current when operating state not, and fringe node sends Edge-Hello message for each subring in RRPP ring group; For example, when RRPP ring group 1 current during in operating state not, fringe node sends Edge-Hello message for subring 1 to assistant edge node, fringe node sends Edge-Hello message for subring 2 to assistant edge node, and fringe node sends Edge-Hello message for subring 3 to assistant edge node.

Step B, fringe node send the 3rd message to assistant edge node, carry the information of RRPP ring group, the information of the information of subring and transmission subring in the 3rd message.For example, in the 3rd message, carrying the RRPP ring group that need to add to is RRPP ring group 1, and the subring that need to add RRPP ring group 1 to is subring 1, subring 2 and subring 3, and the transmission subring in RRPP ring group 1 is subring 1.

In a kind of specific implementation, the 3rd message can be for adding ring group message, and in this interpolation ring group message, carry the information of RRPP ring group, the information of the information of subring and transmission subring, and this interpolation ring group message is used for notifying assistant edge node to add subring (being the information of subring) to RRPP ring group (being the information of RRPP ring group), and for notifying the information of assistant edge node utilization transmission subring to determine the transmission subring of RRPP ring group.For example, the type of message of this interpolation ring group message can be predefined type, as AddRgroup.

Step C, assistant edge node are after receiving the 3rd message, utilize the information of RRPP ring group, the information of subring of carrying in the 3rd message and the information that sends subring on assistant edge node, to configure RRPP ring group, add subring to RRPP ring group, and the transmission subring in definite RRPP ring group, and assistant edge node is only distributed to the Edge-Hello message for sending subring in each subring in RRPP ring group.

For example, assistant edge node is after receiving the 3rd message, on assistant edge node, configure RRPP ring group 1, add subring 1, subring 2 and subring 3 to RRPP ring group 1, and the transmission subring in definite RRPP ring group 1 is subring 1, and assistant edge node is only distributed to the Edge-Hello message for subring 1 in each subring (being subring 1, subring 2 and subring 3) in RRPP ring group 1.

Concrete, if receive the Edge-Hello message for subring 1, because subring 1 is the transmission subring in RRPP ring group 1, so assistant edge node need to be distributed to the Edge-Hello message for subring 1 subring 1, subring 2 and the subring 3 in RRPP ring group 1.Further, if receive the Edge-Hello message for subring 2 or subring 3, because subring 2 and subring 3 are not all the transmission subrings in RRPP ring group 1, so assistant edge node does not need the Edge-Hello message for subring 2 or subring 3 to be distributed to subring 1, subring 2 and the subring 3 in RRPP ring group 1.

Step D, assistant edge node send the 4th message to fringe node, and the 4th message is used for representing that assistant edge node has added subring to RRPP ring group; For example, the 4th message is used for representing that assistant edge node adds subring 1, subring 2 and subring 3 to RRPP ring group 1.

In a kind of concrete implementation, the 4th message can be for adding ring group response message.Wherein, this interpolation ring group response message is used for notifying this assistant edge of fringe node node subring to be added to RRPP ring group.For example, the type of message of this interpolation ring group response message can be predefined type, as RgroupResponse.

Step e, fringe node, after receiving the 4th message, arrange RRPP ring group current in running order, and now RRPP ring group can start normal operation, and specific works process does not repeat them here.

In the embodiment of the present invention, RRPP ring group on fringe node is current when in running order, and fringe node only sends Edge-Hello message for the transmission subring in RRPP ring group.For example, when RRPP ring group 1 current when in running order, fringe node is only the transmission subring in RRPP ring group 1 for subring 1() to assistant edge node, send Edge-Hello message, but fringe node does not need for subring 2 and subring 3, to assistant edge node, to send Edge-Hello message again.

In the above embodiment of the present invention, when configuring RRPP ring group on fringe node, even subring quantity is more in RRPP ring group, can not cause greater impact to equipment performance yet.Concrete, on assistant edge node, configure RRPP ring group, and subring is added to after RRPP ring group, only the Edge-Hello message for sending subring is distributed in each subring in RRPP ring group.Therefore, even if fringe node still sends Edge-Hello message for each subring to assistant edge node, assistant edge node is also only distributed in each subring in RRPP ring group for the Edge-Hello message that sends subring, thereby reduce the quantity that needs the Edge-Hello message of distribution on assistant edge node, avoid equipment performance to impact.

As shown in Figure 3, in the time need to adding the subring of RRPP ring group on assistant edge node (Assistant-edge-node), as: need to the interior interpolation subring 4 in the RRPP ring group 1 of assistant edge node, and RRPP ring group 1 interior current comprised subring 1, subring 2 and subring 3, based on this, the collocation method of the RRPP ring group that embodiment of the present invention proposes comprises the following steps:

Step 301, assistant edge node adds subring to RRPP ring group.

For example, assistant edge node adds subring 4 to RRPP ring group 1, and now, this RRPP ring group 1 is interior will comprise subring 1, subring 2, subring 3 and subring 4.

Step 302, assistant edge node sends the second message to fringe node, and carries the information of RRPP ring group and the information of subring in this second message.For example, in this second message, carrying the RRPP ring group that need to add to is RRPP ring group 1, and the subring that need to add RRPP ring group 1 to is subring 4.

In a kind of specific implementation, the second message can be for adding ring group membership message, and in this interpolation ring group membership message, carry the information of RRPP ring group and the information of subring, and this interpolation ring group membership message is used for notifying fringe node to add subring (being the information of subring) to RRPP ring group (being the information of RRPP ring group).For example, the type of message of this interpolation ring group membership message can be predefined type, as AddRgroupMember.

Step 303, fringe node, after receiving the second message, utilizes the information of RRPP ring group and the information of subring of in the second message, carrying subring to be added to RRPP ring group on fringe node.For example, fringe node is after receiving the second message, owing to carrying the RRPP ring group that need to add in this second message, it is RRPP ring group 1, the subring that need to add RRPP ring group 1 to is subring 4, add subring 4 to RRPP ring group 1, now RRPP ring group 1 comprises subring 1, subring 2 and subring 3, subring 4.

In prior art, when subring quantity is more in RRPP ring group, can cause greater impact to equipment performance.Based on above-mentioned discovery, when above configuring RRPP ring group at assistant edge node (Assistant-edge-node), and while adding the subring of RRPP ring group on assistant edge node, as: on assistant edge node, configure RRPP ring group 1, and in the interior interpolation subring 1 of this RRPP ring group 1, subring 2 and the subring 3 of assistant edge node, the collocation method of the RRPP ring group that embodiment of the present invention proposes comprises the following steps:

Steps A, assistant edge node configuration RRPP ring group, add subring to RRPP ring group, and the subring in RRPP ring group, select a subring as the transmission subring of RRPP ring group.For example, assistant edge node configuration RRPP ring group 1, adds subring 1, subring 2 and subring 3 to RRPP ring group 1, and the subring in RRPP ring group 1, selects subring 1 as the transmission subring of RRPP ring group 1.

Wherein, assistant edge node is only distributed to the Edge-Hello message for sending subring in each subring in RRPP ring group.For example, assistant edge node is only distributed to the Edge-Hello message for subring 1 in each subring (being subring 1, subring 2 and subring 3) in RRPP ring group 1.

Step B, assistant edge node send the 5th message to fringe node, carry the information of RRPP ring group, the information of the information of subring and transmission subring in the 5th message; For example, in the 5th message, carrying the RRPP ring group that need to add to is RRPP ring group 1, and the subring that need to add RRPP ring group 1 to is subring 1, subring 2 and subring 3, and the transmission subring in RRPP ring group 1 is subring 1.

In a kind of specific implementation, the 5th message can be for adding ring group message, and in this interpolation ring group message, carry the information of RRPP ring group, the information of the information of subring and transmission subring, and this interpolation ring group message is used for notifying fringe node to add subring (being the information of subring) to RRPP ring group (being the information of RRPP ring group), and for notifying the information of fringe node utilization transmission subring to determine the transmission subring of RRPP ring group.For example, the type of message of this interpolation ring group message can be predefined type, as AddRgroup.

Step C, fringe node are after receiving the 5th message, utilize the information of RRPP ring group, the information of subring of carrying in the 5th message and the information that sends subring on fringe node, to configure RRPP ring group, add subring to RRPP ring group, and the transmission subring in definite RRPP ring group.For example, fringe node, after receiving the 5th message, configures RRPP ring group 1 on fringe node, adds subring 1, subring 2 and subring 3 to RRPP ring group 1, and the transmission subring in definite RRPP ring group 1 is subring 1.

In the embodiment of the present invention, fringe node sends Edge-Hello message for the transmission subring of RRPP ring group, for example, when RRPP ring group 1 current when in running order, fringe node is only the transmission subring in RRPP ring group 1 for subring 1() to assistant edge node, send Edge-Hello message, but fringe node no longer sends Edge-Hello message for subring 2 and subring 3 to assistant edge node.

In the above embodiment of the present invention, when configuring RRPP ring group on assistant edge node, even subring quantity is more in RRPP ring group, can not cause greater impact to equipment performance yet.Concrete, on assistant edge node, configure RRPP ring group, and subring is added to after RRPP ring group, only the Edge-Hello message for sending subring is distributed in each subring in RRPP ring group.Even if therefore fringe node still sends Edge-Hello message for each subring to assistant edge node, assistant edge node is also only distributed to each subring in RRPP ring group for the Edge-Hello message that sends subring, thereby reduce the quantity that needs the Edge-Hello message of distribution on assistant edge node, avoid equipment performance to impact.

As shown in Figure 4, when when fringe node (Edge-node) is above deleted the subring of RRPP ring group, as: RRPP ring group 1 has comprised subring 1, subring 2 and subring 3, in the interior deletion subring 2 of RRPP ring group 1 of fringe node, the collocation method of the RRPP ring group that embodiment of the present invention proposes comprises the following steps:

Step 401, fringe node is deleted subring from RRPP ring group.For example, fringe node is deleted subring 2 from RRPP ring group 1, now in RRPP ring group 1, comprises subring 1 and subring 3.

Step 402, fringe node sends the 6th message to assistant edge node, and in the 6th message, carries the information of RRPP ring group and the information of subring.For example, in the 6th message, carrying the RRPP ring group that need to delete subring is RRPP ring group 1, and needing the subring of deleting is the subring 2 of RRPP ring group 1.

In a kind of specific implementation, the 6th message can be for deleting ring group membership message, and in this deletion ring group membership message, carry the information of RRPP ring group and the information of subring, and this deletion ring group membership message is used for notifying assistant edge node that subring (being the information of subring) is deleted from RRPP ring group (being the information of RRPP ring group).For example, the type of message of this deletion ring group membership message can be predefined type, as DelRgroupMember.

Step 403, assistant edge node, after the 6th message of receiving from fringe node, utilizes the information of RRPP ring group and the information of subring of in the 6th message, carrying from RRPP ring group, to delete subring on assistant edge node.For example, assistant edge node, after the 6th message of receiving from fringe node, is deleted subring 2 from RRPP ring group 1, now in RRPP ring group 1, comprises subring 1 and subring 3.

In prior art, when subring quantity is more in RRPP ring group, can cause greater impact to equipment performance.Based on above-mentioned discovery, in the embodiment of the present invention, when subring that fringe node is deleted from RRPP ring group is the transmission subring in RRPP ring group, fringe node also need to select a subring as the transmission subring of RRPP ring group the subring in RRPP ring group, and in the 6th message, also carries the information of this transmission subring; Further, assistant edge node, after receiving the 6th message, also needs to utilize the information of the transmission subring of carrying in the 6th message to redefine the transmission subring in RRPP ring group.

In the embodiment of the present invention, when in the upper deletion of fringe node (Edge-node) RRPP ring group, as: on fringe node, subring 1, subring 2 and subring 3 are deleted from RRPP ring group 1, and delete RRPP ring group 1, the collocation method of the RRPP ring group that embodiment of the present invention proposes comprises the following steps:

Steps A, fringe node are deleted RRPP ring group.For example, fringe node is deleted subring 1, subring 2 and subring 3 from RRPP ring group 1, and deletes this RRPP ring group 1.

Step B, fringe node send the 8th message to assistant edge node, carry the information of RRPP ring group in the 8th message.For example, in the 8th message, carrying the RRPP ring group that need to delete is RRPP ring group 1.

In a kind of specific implementation, the 8th message can be deletion ring group message, and deletes the information of carrying RRPP ring group in ring group message, and this deletion ring group message is used for notifying assistant edge node that RRPP ring group (being the information of RRPP ring group) is deleted.For example, the type of message of this deletion ring group message can be predefined type, as DelRgroup.

Step C, assistant edge node, after receiving the 8th message, utilize the information of RRPP ring group on assistant edge node, to delete RRPP ring group.For example, assistant edge node, after receiving the 8th message, is deleted subring 1, subring 2 and subring 3 from RRPP ring group 1, and deletes this RRPP ring group 1.

In the embodiment of the present invention, before RRPP ring group is not deleted, fringe node sends Edge-Hello message for the transmission subring of RRPP ring group; For example, before RRPP ring group 1 is not deleted, fringe node only sends subring for subring 1() to assistant edge node, send Edge-Hello message, but fringe node does not need for subring 2 and subring 3, to assistant edge node, to send Edge-Hello message again.

In the embodiment of the present invention, before RRPP ring group is not deleted, assistant edge node is distributed to the Edge-Hello message for sending subring in each subring of RRPP ring group.For example, before RRPP ring group 1 is not deleted, if receive the Edge-Hello message for subring 1, because subring 1 is the transmission subring in RRPP ring group 1, so assistant edge node need to be distributed to the Edge-Hello message for subring 1 subring 1, subring 2 and the subring 3 in RRPP ring group 1.Further, if receive the Edge-Hello message for subring 2 or subring 3, because subring 2 and subring 3 are not all the transmission subrings in RRPP ring group 1, so assistant edge node does not need the Edge-Hello message for subring 2 or subring 3 to be distributed to subring 1, subring 2 and the subring 3 in RRPP ring group 1.

In the above embodiment of the present invention, when deleting RRPP ring group on fringe node, even subring quantity is more in RRPP ring group, can not cause greater impact to equipment performance yet.Concrete, when fringe node is deleted subring from RRPP ring group, assistant edge node is only distributed to the Edge-Hello message for sending subring in each subring in RRPP ring group.Therefore, even if fringe node still sends Edge-Hello message for each subring to assistant edge node, assistant edge node is also only distributed in each subring in RRPP ring group for the Edge-Hello message that sends subring, thereby reduce the quantity that needs the Edge-Hello message of distribution on assistant edge node, avoid equipment performance to impact.

As shown in Figure 5, when in the upper subring of deleting in RRPP ring group of assistant edge node (Assistant-edge-node), as: RRPP ring group 1 interior current comprised subring 1, subring 2 and subring 3, and need to delete subring 2 the RRPP ring group 1 of assistant edge node is interior, based on this, the collocation method of the RRPP ring group that embodiment of the present invention proposes comprises the following steps:

Step 501, assistant edge node is deleted subring from RRPP ring group.For example, assistant edge node is deleted subring 2 from RRPP ring group 1, now in RRPP ring group 1, comprises subring 1 and subring 3.

Step 502, assistant edge node sends the 7th message to fringe node, and in the 7th message, carries the information of RRPP ring group and the information of subring.For example, in the 7th message, carrying the RRPP ring group that need to delete subring is RRPP ring group 1, and needing the subring of deleting is the subring 2 of RRPP ring group 1.

In a kind of specific implementation, the 7th message can be for deleting ring group membership message, and in this deletion ring group membership message, carry the information of RRPP ring group and the information of subring, and this deletion ring group membership message is used for notifying fringe node that subring (being the information of subring) is deleted from RRPP ring group (being the information of RRPP ring group).For example, the type of message of this deletion ring group membership message can be predefined type, as DelRgroupMember.

Step 503, fringe node, after the 7th message of receiving from assistant edge node, utilizes the information of RRPP ring group and the information of subring of in the 7th message, carrying from RRPP ring group, to delete subring on fringe node.For example, fringe node, after the 7th message of receiving from assistant edge node, is deleted subring 2 from RRPP ring group 1, now in RRPP ring group 1, comprises subring 1 and subring 3.

In prior art, when subring quantity is more in RRPP ring group, can cause greater impact to equipment performance.Based on above-mentioned discovery, in the embodiment of the present invention, when subring that assistant edge node is deleted from RRPP ring group is the transmission subring in RRPP ring group, assistant edge node also need to select a subring as the transmission subring of RRPP ring group the subring in RRPP ring group, and in the 7th message, also carries the information of this transmission subring; Further, fringe node, after receiving the 7th message, also needs to utilize the information of the transmission subring of carrying in the 7th message to redefine the transmission subring in RRPP ring group.

In the embodiment of the present invention, when in the upper deletion of assistant edge node (Assistant-edge-node) RRPP ring group, as subring 1, subring 2 and subring 3 deleted from RRPP ring group 1 on assistant edge node, and delete RRPP ring group 1, the collocation method of the RRPP ring group of the embodiment of the present invention comprises the following steps:

Steps A, assistant edge node send the 9th message to fringe node, carry the information of RRPP ring group in the 9th message.For example, in the 9th message, carrying the RRPP ring group that need to delete is RRPP ring group 1.

In a kind of specific implementation, the 9th message can be deletion ring group message, and deletes the information of carrying RRPP ring group in ring group message, and this deletion ring group message is used for notifying fringe node that RRPP ring group (being the information of RRPP ring group) is deleted.For example, the type of message of this deletion ring group message can be predefined type, as DelRgroup.

Step B, fringe node, after receiving the 9th message, utilize the information of the RRPP ring group of carrying in the 9th message on fringe node, to delete RRPP ring group.For example, fringe node, after receiving the 9th message, is deleted subring 1, subring 2 and subring 3 from RRPP ring group 1, and deletes this RRPP ring group 1.

Step C, fringe node send the tenth message to assistant edge node, and the tenth message is used for representing that fringe node deleted RRPP ring group.For example, the tenth message is for representing to have deleted RRPP ring group 1.

In a kind of concrete implementation, the tenth message can be for deleting ring group response message.Wherein, this deletion ring group response message is for notifying the assistant edge node RRPP ring group that this fringe node has been deleted.For example, the type of message of this deletion ring group response message can be predefined type, as DelRgroupResponse.

Step D, assistant edge node, after receiving the tenth message, are deleted RRPP ring group on assistant edge node.For example, assistant edge node is after receiving the tenth message, and assistant edge node is deleted subring 1, subring 2 and subring 3 from RRPP ring group 1, and deletes this RRPP ring group 1.

In the above embodiment of the present invention, when deleting RRPP ring group on assistant edge node, even subring quantity is more in RRPP ring group, can not cause greater impact to equipment performance yet.Concrete, when deleting RRPP ring group on assistant edge node, assistant edge node is only distributed to the Edge-Hello message for sending subring in each subring in RRPP ring group.Therefore, even if fringe node still sends Edge-Hello message for each subring to assistant edge node, assistant edge node is also only distributed in each subring in RRPP ring group for the Edge-Hello message that sends subring, thereby reduce the quantity that needs the Edge-Hello message of distribution on assistant edge node, avoid equipment performance to impact.
