Description

Configuration method and equipment of RRPP (Rapid Ring protection protocol) ring group

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for configuring an RRPP ring group.

Background

RRPP (fast Ring Protection Protocol) is a link layer Protocol specifically applied to ethernet rings. Among them, the RRPP has a high convergence rate. When the Ethernet ring is complete, the RRPP can prevent the broadcast storm caused by the data loop; when one link on the Ethernet ring is disconnected, the RRPP can quickly recover the communication path between each node on the ring network.

Fig. 1 is a schematic view of an application scenario of the RRPP network. In the RRPP network, each device is called a node, and the roles of the nodes are divided into the following: (1) a master node: each ring has a master node, which is the primary operating node that initiates loop detection and loop prevention. (2) A transmission node: all other nodes except the main node on the main ring are transmission nodes; all nodes on the sub-ring except the master node and the node where the sub-ring intersects the master ring are transmission nodes. (3) Edge nodes: and the edge node is a special transmission node, the role of the edge node on the main ring is a transmission node, and the role of the edge node on the subring is an edge node. (4) Auxiliary edge nodes: and the auxiliary edge node is a special transmission node, the role of the auxiliary edge node on the main ring is a transmission node, and the role of the auxiliary edge node on the subring is an auxiliary edge node.

In order to detect a main ring link between an Edge node and an auxiliary Edge node, the Edge node sends an Edge-Hello (Edge health detection) message to the auxiliary Edge node. In order to reduce the receiving and sending quantity of the Edge-Hello messages, RRPP ring groups are respectively configured on the Edge nodes and the auxiliary Edge nodes, and the RRPP ring groups are a set of sub-rings. For example, Edge nodes of the sub-ring 1, the sub-ring 2, and the sub-ring 3 are configured on the same device 1, auxiliary Edge nodes of the sub-ring 1, the sub-ring 2, and the sub-ring 3 are configured on the same device 2, and main ring links corresponding to the sub-rings where the Edge nodes and the auxiliary Edge nodes are located are the same, that is, Edge-Hello packets sent by the Edge nodes of the sub-ring 1, the sub-ring 2, and the sub-ring 3 reach the auxiliary Edge nodes through the same path, so that the sub-ring 1, the sub-ring 2, and the sub-ring 3 can be configured to the RRPP ring group. Based on this, an RRPP ring group 1 may be configured on the edge node, where the RRPP ring group 1 includes a sub-ring 1, a sub-ring 2, and a sub-ring 3; and an RRPP ring group 1 may be configured on the auxiliary edge node, where the RRPP ring group 1 includes a sub-ring 1, a sub-ring 2, and a sub-ring 3.

Aiming at a subring 1, a subring 2 and a subring 3 in an RRPP ring group 1, an Edge node only needs to send an Edge-Hello message to an auxiliary Edge node; after receiving the Edge-Hello packet, the auxiliary Edge node needs to distribute the Edge-Hello packet to the sub-ring 1, the sub-ring 2, and the sub-ring 3, respectively.

In the prior art, when configuring the RRPP ring group, it is necessary to manually configure the RRPP ring group on the edge node and the auxiliary edge node, respectively, and the configuration requirements of the RRPP ring group are as follows: (1) when adding the subring into the RRPP ring group, the subring needs to be added into the RRPP ring group on the auxiliary edge node, and then the subring is added into the RRPP ring group on the edge node; (2) when deleting the subring from the RRPP ring group, the subring needs to be deleted from the RRPP ring group on the edge node, and then the subring needs to be deleted from the RRPP ring group on the auxiliary edge node; (3) when deleting the whole RRPP ring group, the whole RRPP ring group needs to be deleted on the edge node first, and then the whole RRPP ring group needs to be deleted on the auxiliary edge node.

Obviously, in the prior art, the configuration workload is large, the configuration of the RRPP ring group is too complex, and the user needs to configure the RRPP ring group according to the requirement, there is an order dependency relationship (i.e. the configuration requirement of the RRPP ring group) in the configuration process, the configuration requirement of the user is high, and the configuration is easy to make mistakes.

Detailed Description

The embodiment of the invention provides a configuration method of an RRPP ring group, which is applied to an RRPP network comprising edge nodes and auxiliary edge nodes, and completes the addition of sub-rings in the RRPP ring group or the deletion of sub-rings in the RRPP ring group by carrying out information interaction between the edge nodes and the auxiliary edge nodes. This process is described in detail below with reference to the flow of the method for configuring the RRPP ring set shown in fig. 2-5.

As shown in fig. 2, when adding a sub-ring of the RRPP ring group on an Edge node (Edge-node), as follows: adding a subring 4 in an RRPP ring group 1 of an edge node, where the RRPP ring group 1 already includes a subring 1, a subring 2, and a subring 3, and a configuration method of the RRPP ring group provided by the embodiment of the present invention includes the following steps:

in step 201, the edge node adds a sub-ring to the RRPP ring group. For example, the edge node adds sub-ring 4 to RRPP ring group 1, when RRPP ring group 1 contains sub-ring 1, sub-ring 2, sub-ring 3, and sub-ring 4.

Step 202, the edge node sends a first message to the auxiliary edge node, and the first message carries the information of the RRPP ring group and the information of the subring. For example, the first message carries the RRPP ring group to be added as the RRPP ring group 1, and the sub-ring to be added to the RRPP ring group 1 is the sub-ring 4.

In a specific implementation manner, the first packet may be an adding ring group member packet, and the adding ring group member packet carries information of the RRPP ring group and information of the subring, and the adding ring group member packet is used to notify the auxiliary edge node to add the subring (i.e., information of the subring) to the RRPP ring group (i.e., information of the RRPP ring group). For example, the message type of the add ring group member message may be a predetermined type, such as AddRgroupMember.

Step 203, after the auxiliary edge node receives the first message, the auxiliary edge node adds the subring to the RRPP ring group on the auxiliary edge node by using the information of the RRPP ring group and the information of the subring carried in the first message. For example, after receiving the first message, the auxiliary edge node adds the subring 4 to the RRPP ring group 1 because the RRPP ring group to be added is carried in the first message as the RRPP ring group 1, and the subring to be added to the RRPP ring group 1 is the subring 4, where the RRPP ring group 1 includes the subring 1, the subring 2, the subring 3, and the subring 4.

In the prior art, when the number of subrings in the RRPP ring group is large, the performance of the device is greatly impacted. For example, a user configures an RRPP ring group on the secondary edge node, where there are 64 sub-rings in the RRPP ring group; before configuring the RRPP ring group on the Edge node, the Edge node still sends an Edge-Hello message to the auxiliary Edge node for each sub-ring, and since the RRPP ring group is enabled on the auxiliary Edge node, the auxiliary Edge node distributes the Edge-Hello message to 64 sub-rings after receiving the Edge-Hello message of the sub-ring 1, and so on, and after receiving the Edge-Hello message of the sub-ring 64, the auxiliary Edge node distributes the Edge-Hello message to 64 sub-rings. Further, if the Edge node sends 2 Edge-Hello packets per second for each sub-ring, the auxiliary Edge node needs to distribute 64 × 2 × 64 Edge-Hello packets per second, thereby causing a large impact on the device performance.

Further, based on the above findings, when configuring the RRPP ring group on the Edge node (Edge-node) and adding the sub-rings of the RRPP ring group on the Edge node, such as: an RRPP ring group 1 is configured on an edge node, and a sub-ring 1, a sub-ring 2, and a sub-ring 3 are added in the RRPP ring group 1 of the edge node, so that the method for configuring an RRPP ring group provided by the embodiment of the present invention includes the following steps:

step A, configuring an RRPP ring group by the edge node, adding the subring into the RRPP ring group, selecting one subring from the subrings in the RRPP ring group as a sending subring of the RRPP ring group, and setting the RRPP ring group to be in a non-working state currently. For example, the edge node configures an RRPP ring group 1, adds a sub-ring 1, a sub-ring 2, and a sub-ring 3 to the RRPP ring group 1, selects the sub-ring 1 from sub-rings within the RRPP ring group 1 as a transmission sub-ring of the RRPP ring group 1, and sets the RRPP ring group 1 to be currently in an inoperative state.

In the embodiment of the invention, when the RRPP ring group on the Edge node is in a non-working state at present, the Edge node sends an Edge-Hello message aiming at each sub-ring in the RRPP ring group; for example, when the RRPP ring group 1 is currently in an inactive state, the Edge node sends an Edge-Hello packet to the auxiliary Edge node for the sub-ring 1, the Edge node sends an Edge-Hello packet to the auxiliary Edge node for the sub-ring 2, and the Edge node sends an Edge-Hello packet to the auxiliary Edge node for the sub-ring 3.

And step B, the edge node sends a third message to the auxiliary edge node, wherein the third message carries the information of the RRPP ring group, the information of the subring and the information of the sending subring. For example, the third message carries the RRPP ring group to be added as RRPP ring group 1, the sub-rings to be added to RRPP ring group 1 are sub-ring 1, sub-ring 2, and sub-ring 3, and the sending sub-ring in RRPP ring group 1 is sub-ring 1.

In a specific implementation manner, the third packet may be an adding ring group packet, where the adding ring group packet carries information of the RRPP ring group, information of the subring, and information of the sending subring, and the adding ring group packet is used to notify the auxiliary edge node to add the subring (i.e., information of the subring) to the RRPP ring group (i.e., information of the RRPP ring group), and is used to notify the auxiliary edge node to determine the sending subring of the RRPP ring group by using the information of the sending subring. For example, the message type of the add ring group message may be a predetermined type, such as AddRgroup.

And step C, after receiving the third message, the auxiliary Edge node configures the RRPP ring group on the auxiliary Edge node by utilizing the information of the RRPP ring group, the information of the subring and the information of the sending subring carried in the third message, adds the subring to the RRPP ring group, determines the sending subring in the RRPP ring group, and only distributes the Edge-Hello message aiming at the sending subring to each subring in the RRPP ring group.

For example, after receiving the third packet, the auxiliary Edge node configures an RRPP ring group 1 on the auxiliary Edge node, adds sub-ring 1, sub-ring 2, and sub-ring 3 to the RRPP ring group 1, and determines that the sending sub-ring in the RRPP ring group 1 is the sub-ring 1, and the auxiliary Edge node only distributes the Edge-Hello packet for the sub-ring 1 to each sub-ring (i.e., the sub-ring 1, the sub-ring 2, and the sub-ring 3) in the RRPP ring group 1.

Specifically, if the Edge-Hello packet for the sub-ring 1 is received, since the sub-ring 1 is the sending sub-ring in the RRPP ring group 1, the auxiliary Edge node needs to distribute the Edge-Hello packet for the sub-ring 1 to the sub-ring 1, the sub-ring 2, and the sub-ring 3 in the RRPP ring group 1. Further, if the Edge-Hello packet for the sub-ring 2 or the sub-ring 3 is received, since neither the sub-ring 2 nor the sub-ring 3 is the sending sub-ring in the RRPP ring group 1, the auxiliary Edge node does not need to distribute the Edge-Hello packet for the sub-ring 2 or the sub-ring 3 to the sub-ring 1, the sub-ring 2, and the sub-ring 3 in the RRPP ring group 1.

Step D, the auxiliary edge node sends a fourth message to the edge node, and the fourth message is used for indicating that the auxiliary edge node adds the subring to the RRPP ring group; for example, the fourth packet is used to indicate that the secondary edge node has added sub-ring 1, sub-ring 2, and sub-ring 3 to RRPP ring group 1.

In a specific implementation manner, the fourth packet may be an add ring group response packet. Wherein, the ring group adding response message is used to inform the edge node that the auxiliary edge node has added the subring to the RRPP ring group. For example, the message type of the add ring group response message may be a preset type, such as RgroupResponse.

And step E, after receiving the fourth message, the edge node sets the RRPP ring group to be in a working state at present, and at this moment, the RRPP ring group can start to work normally, and the specific working process is not repeated.

In the embodiment of the invention, when the RRPP ring group on the Edge node is in a working state at present, the Edge node only sends the Edge-Hello message aiming at the sending sub-ring in the RRPP ring group. For example, when the RRPP ring group 1 is currently in the working state, the Edge node sends an Edge-Hello packet to the auxiliary Edge node only for the sub-ring 1 (i.e., the sending sub-ring in the RRPP ring group 1), but the Edge node does not need to send the Edge-Hello packet to the auxiliary Edge node for the sub-ring 2 and the sub-ring 3 any more.

In the above embodiments of the present invention, when the RRPP ring group is configured on the edge node, even if the number of sub-rings in the RRPP ring group is large, the device performance is not greatly impacted. Specifically, the auxiliary Edge node configures an RRPP ring group, adds a sub-ring to the RRPP ring group, and then only distributes an Edge-Hello packet for transmitting the sub-ring to each sub-ring in the RRPP ring group. Therefore, even if the Edge node still sends the Edge-Hello message to the auxiliary Edge node for each sub-ring, the auxiliary Edge node only distributes the Edge-Hello message for sending the sub-ring to each sub-ring in the RRPP ring group, thereby reducing the number of the Edge-Hello messages needing to be distributed on the auxiliary Edge node and avoiding causing impact on the performance of the equipment.

As shown in fig. 3, when a sub-ring of the RRPP ring group needs to be added on the auxiliary edge node (assist-edge-node), such as: the sub-ring 4 needs to be added into the RRPP ring group 1 of the auxiliary edge node, and the RRPP ring group 1 currently includes the sub-ring 1, the sub-ring 2, and the sub-ring 3, based on this, the method for configuring the RRPP ring group provided by the embodiment of the present invention includes the following steps:

in step 301, the secondary edge node adds a sub-ring to the RRPP ring group.

For example, the auxiliary edge node adds sub-ring 4 to RRPP ring set 1, at which point sub-ring 1, sub-ring 2, sub-ring 3, and sub-ring 4 will be included within RRPP ring set 1.

Step 302, the auxiliary edge node sends a second message to the edge node, and the second message carries the information of the RRPP ring group and the information of the subring. For example, the second message carries the RRPP ring group to be added as the RRPP ring group 1, and the sub-ring to be added to the RRPP ring group 1 is the sub-ring 4.

In a specific implementation manner, the second packet may be an adding ring group member packet, and the adding ring group member packet carries information of the RRPP ring group and information of the subring, and the adding ring group member packet is used to notify the edge node to add the subring (i.e., information of the subring) to the RRPP ring group (i.e., information of the RRPP ring group). For example, the message type of the add ring group member message may be a predetermined type, such as AddRgroupMember.

Step 303, after receiving the second message, the edge node adds the subring to the RRPP ring group on the edge node by using the information of the RRPP ring group and the information of the subring carried in the second message. For example, after receiving the second message, the edge node adds the subring 4 to the RRPP ring group 1 because the RRPP ring group to be added is carried in the second message and is the RRPP ring group 1, and the subring to be added to the RRPP ring group 1 is the subring 4, where the RRPP ring group 1 includes the subring 1, the subring 2, the subring 3, and the subring 4.

In the prior art, when the number of subrings in the RRPP ring group is large, the performance of the device is greatly impacted. Based on the above findings, when the RRPP ring group is configured on the auxiliary edge node (assist-edge-node), and the sub-rings of the RRPP ring group are added on the auxiliary edge node, such as: configuring an RRPP ring group 1 on an auxiliary edge node, and adding a sub-ring 1, a sub-ring 2, and a sub-ring 3 in the RRPP ring group 1 of the auxiliary edge node, the method for configuring an RRPP ring group provided in the embodiment of the present invention includes the following steps:

and step A, configuring an RRPP ring group by the auxiliary edge node, adding the subring to the RRPP ring group, and selecting one subring from the subrings in the RRPP ring group as a sending subring of the RRPP ring group. For example, the auxiliary edge node configures an RRPP ring group 1, adds sub-ring 1, sub-ring 2, and sub-ring 3 to the RRPP ring group 1, and selects sub-ring 1 as a transmission sub-ring of the RRPP ring group 1 from among sub-rings within the RRPP ring group 1.

And the auxiliary Edge node only distributes the Edge-Hello message aiming at the sending sub-ring to each sub-ring in the RRPP ring group. For example, the auxiliary Edge node only distributes the Edge-Hello packet for sub-ring 1 to each sub-ring (i.e., sub-ring 1, sub-ring 2, and sub-ring 3) in the RRPP ring group 1.

Step B, the auxiliary edge node sends a fifth message to the edge node, wherein the fifth message carries the information of the RRPP ring group, the information of the subring and the information of the sending subring; for example, the fifth message carries the RRPP ring group to be added as RRPP ring group 1, the sub-rings to be added to RRPP ring group 1 are sub-ring 1, sub-ring 2, and sub-ring 3, and the sending sub-ring in RRPP ring group 1 is sub-ring 1.

In a specific implementation manner, the fifth packet may be an adding ring group packet, where the adding ring group packet carries information of an RRPP ring group, information of a subring, and information of a sending subring, and the adding ring group packet is used to notify the edge node to add the subring (i.e., information of the subring) to the RRPP ring group (i.e., information of the RRPP ring group), and is used to notify the edge node to determine the sending subring of the RRPP ring group by using the information of the sending subring. For example, the message type of the add ring group message may be a predetermined type, such as AddRgroup.

And step C, after receiving the fifth message, the edge node configures the RRPP ring group on the edge node by utilizing the information of the RRPP ring group, the information of the subring and the information of the sending subring carried in the fifth message, adds the subring to the RRPP ring group, and determines the sending subring in the RRPP ring group. For example, after receiving the fifth packet, the edge node configures an RRPP ring group 1 on the edge node, adds the subring 1, the subring 2, and the subring 3 to the RRPP ring group 1, and determines that the sending subring in the RRPP ring group 1 is the subring 1.

In the embodiment of the present invention, the Edge node sends an Edge-Hello packet to the sending sub-ring of the RRPP ring group, for example, when the RRPP ring group 1 is currently in a working state, the Edge node sends the Edge-Hello packet to the auxiliary Edge node only to the sub-ring 1 (i.e., the sending sub-ring in the RRPP ring group 1), but the Edge node does not send the Edge-Hello packet to the auxiliary Edge node to the

sub-rings

2 and 3.

In the above embodiments of the present invention, when the RRPP ring group is configured on the auxiliary edge node, even if the number of sub-rings in the RRPP ring group is large, the device performance will not be impacted greatly. Specifically, the auxiliary Edge node configures an RRPP ring group, adds a sub-ring to the RRPP ring group, and then only distributes an Edge-Hello packet for transmitting the sub-ring to each sub-ring in the RRPP ring group. Therefore, even if the Edge node still sends the Edge-Hello message to the auxiliary Edge node aiming at each sub-ring, the auxiliary Edge node only distributes the Edge-Hello message for sending the sub-ring to each sub-ring in the RRPP ring group, thereby reducing the number of the Edge-Hello messages needing to be distributed on the auxiliary Edge node and avoiding the impact on the equipment performance.

As shown in fig. 4, when deleting a sub-ring of the RRPP ring group on an Edge node (Edge-node), as follows: the RRPP ring group 1 already includes the sub-ring 1, the sub-ring 2, and the sub-ring 3, and the sub-ring 2 is deleted from the RRPP ring group 1 of the edge node, so that the method for configuring the RRPP ring group provided by the embodiment of the present invention includes the following steps:

in step 401, the edge node deletes the sub-ring from the RRPP ring group. For example, the edge node deletes sub-ring 2 from RRPP ring group 1, and now sub-ring 1 and sub-ring 3 are included in RRPP ring group 1.

Step 402, the edge node sends a sixth message to the auxiliary edge node, and the sixth message carries the information of the RRPP ring group and the information of the subring. For example, the RRPP ring group that carries the subring to be deleted in the sixth message is the RRPP ring group 1, and the subring to be deleted is the subring 2 of the RRPP ring group 1.

In a specific implementation manner, the sixth message may be a delete ring group member message, and the delete ring group member message carries information of the RRPP ring group and information of the subring, and the delete ring group member message is used to notify the auxiliary edge node to delete the subring (i.e., information of the subring) from the RRPP ring group (i.e., information of the RRPP ring group). For example, the message type of the delete ring group member message may be a predetermined type, such as DelRgroupMember.

Step 403, after the auxiliary edge node receives the sixth message from the edge node, the auxiliary edge node deletes the sub-ring from the RRPP ring group on the auxiliary edge node by using the information of the RRPP ring group and the information of the sub-ring carried in the sixth message. For example, after receiving the sixth packet from the edge node, the auxiliary edge node deletes sub-ring 2 from RRPP ring group 1, where the RRPP ring group 1 includes sub-ring 1 and sub-ring 3.

In the prior art, when the number of subrings in the RRPP ring group is large, the performance of the device is greatly impacted. Based on the above findings, in the embodiment of the present invention, when the sub-ring deleted by the edge node from the RRPP ring group is the sending sub-ring in the RRPP ring group, the edge node further needs to select one sub-ring from the sub-rings in the RRPP ring group as the sending sub-ring of the RRPP ring group, and the sixth message further carries information of the sending sub-ring; further, after receiving the sixth message, the auxiliary edge node needs to determine the sending sub-ring in the RRPP ring group again by using the sending sub-ring information carried in the sixth message.

In the embodiment of the present invention, when deleting an RRPP ring group on an Edge node (Edge-node), for example: deleting the subring 1, the subring 2 and the subring 3 from the RRPP ring group 1 on the edge node, and deleting the RRPP ring group 1, so that the method for configuring the RRPP ring group provided by the embodiment of the present invention includes the following steps:

and step A, deleting the RRPP ring group by the edge node. For example, the edge node deletes sub-ring 1, sub-ring 2, and sub-ring 3 from RRPP ring group 1, and deletes the RRPP ring group 1.

And step B, the edge node sends an eighth message to the auxiliary edge node, wherein the eighth message carries the information of the RRPP ring group. For example, the eighth message carries the RRPP ring group to be deleted as RRPP ring group 1.

In a specific implementation manner, the eighth message may be a delete ring group message, and the delete ring group message carries information of the RRPP ring group, where the delete ring group message is used to notify the auxiliary edge node to delete the RRPP ring group (i.e., information of the RRPP ring group). For example, the message type of the delete ring group message may be a predetermined type, such as delr group.

And step C, after the auxiliary edge node receives the eighth message, deleting the RRPP ring group on the auxiliary edge node by using the information of the RRPP ring group. For example, after receiving the eighth packet, the auxiliary edge node deletes sub-ring 1, sub-ring 2, and sub-ring 3 from the RRPP ring group 1, and deletes the RRPP ring group 1.

In the embodiment of the invention, before the RRPP ring group is not deleted, the Edge node sends an Edge-Hello message aiming at the sending sub-ring of the RRPP ring group; for example, before the RRPP ring group 1 is not deleted, the Edge node sends an Edge-Hello packet to the secondary Edge node only for the sub-ring 1 (i.e., sending the sub-ring), but the Edge node does not need to send the Edge-Hello packet to the secondary Edge node for the sub-ring 2 and the sub-ring 3.

In the embodiment of the invention, before the RRPP ring group is not deleted, the auxiliary Edge node distributes the Edge-Hello message aiming at the sending sub-ring to each sub-ring of the RRPP ring group. For example, before the RRPP ring group 1 is not deleted, if an Edge-Hello packet for the sub-ring 1 is received, since the sub-ring 1 is a sending sub-ring in the RRPP ring group 1, the auxiliary Edge node needs to distribute the Edge-Hello packet for the sub-ring 1 to the sub-ring 1, the sub-ring 2, and the sub-ring 3 in the RRPP ring group 1. Further, if the Edge-Hello packet for the sub-ring 2 or the sub-ring 3 is received, since neither the sub-ring 2 nor the sub-ring 3 is the sending sub-ring in the RRPP ring group 1, the auxiliary Edge node does not need to distribute the Edge-Hello packet for the sub-ring 2 or the sub-ring 3 to the sub-ring 1, the sub-ring 2, and the sub-ring 3 in the RRPP ring group 1.

In the above embodiment of the present invention, when deleting the RRPP ring group on the edge node, even if the number of sub-rings in the RRPP ring group is large, a large impact on the device performance is not caused. Specifically, when the Edge node deletes a sub-ring from the RRPP ring group, the auxiliary Edge node only distributes the Edge-Hello packet for sending the sub-ring to each sub-ring in the RRPP ring group. Therefore, even if the Edge node still sends the Edge-Hello message to the auxiliary Edge node for each sub-ring, the auxiliary Edge node only distributes the Edge-Hello message for sending the sub-ring to each sub-ring in the RRPP ring group, thereby reducing the number of the Edge-Hello messages needing to be distributed on the auxiliary Edge node and avoiding causing impact on the performance of the equipment.

As shown in fig. 5, when a sub-ring within the RRPP ring group is deleted on the auxiliary edge node (assist-edge-node), as follows: the RRPP ring group 1 currently includes a sub-ring 1, a sub-ring 2, and a sub-ring 3, and the sub-ring 2 needs to be deleted in the RRPP ring group 1 of the auxiliary edge node, based on this, the method for configuring the RRPP ring group provided in the embodiment of the present invention includes the following steps:

in step 501, the auxiliary edge node deletes the sub-ring from the RRPP ring group. For example, the auxiliary edge node deletes sub-ring 2 from RRPP ring group 1, and now sub-ring 1 and sub-ring 3 are included in RRPP ring group 1.

Step 502, the auxiliary edge node sends a seventh message to the edge node, and the seventh message carries the information of the RRPP ring group and the information of the subring. For example, the seventh message carries the RRPP ring group that needs to delete the subring as RRPP ring group 1, and the subring that needs to delete is subring 2 of RRPP ring group 1.

In a specific implementation manner, the seventh message may be a delete ring group member message, and the delete ring group member message carries information of the RRPP ring group and information of the subring, and the delete ring group member message is used to notify the edge node to delete the subring (i.e., information of the subring) from the RRPP ring group (i.e., information of the RRPP ring group). For example, the message type of the delete ring group member message may be a predetermined type, such as DelRgroupMember.

In step 503, after receiving the seventh packet from the auxiliary edge node, the edge node deletes the sub-ring from the RRPP ring group on the edge node by using the information of the RRPP ring group and the information of the sub-ring carried in the seventh packet. For example, after receiving the seventh packet from the auxiliary edge node, the edge node deletes sub-ring 2 from RRPP ring group 1, where the RRPP ring group 1 includes sub-ring 1 and sub-ring 3.

In the prior art, when the number of subrings in the RRPP ring group is large, the performance of the device is greatly impacted. Based on the above findings, in the embodiment of the present invention, when the sub-ring deleted from the RRPP ring group by the auxiliary edge node is the sending sub-ring in the RRPP ring group, the auxiliary edge node further needs to select one sub-ring from the sub-rings in the RRPP ring group as the sending sub-ring of the RRPP ring group, and the seventh message further carries information of the sending sub-ring; further, after receiving the seventh packet, the edge node needs to determine the sending sub-ring in the RRPP ring group again by using the sending sub-ring information carried in the seventh packet.

In the embodiment of the present invention, when deleting an RRPP ring group on an auxiliary edge node (assist-edge-node), for example, deleting sub-ring 1, sub-ring 2, and sub-ring 3 from the RRPP ring group 1 and deleting the RRPP ring group 1 on the auxiliary edge node, the method for configuring an RRPP ring group in the embodiment of the present invention includes the following steps:

and step A, the auxiliary edge node sends a ninth message to the edge node, wherein the ninth message carries the information of the RRPP ring group. For example, the ninth message carries the RRPP ring group to be deleted, which is RRPP ring group 1.

In a specific implementation manner, the ninth message may be a delete ring group message, and the delete ring group message carries information of the RRPP ring group, where the delete ring group message is used to notify the edge node to delete the RRPP ring group (i.e., the information of the RRPP ring group). For example, the message type of the delete ring group message may be a predetermined type, such as delr group.

And step B, after the edge node receives the ninth message, deleting the RRPP ring group on the edge node by using the information of the RRPP ring group carried in the ninth message. For example, after receiving the ninth packet, the edge node deletes sub-ring 1, sub-ring 2, and sub-ring 3 from the RRPP ring group 1, and deletes the RRPP ring group 1.

And step C, the edge node sends a tenth message to the auxiliary edge node, wherein the tenth message is used for indicating that the RRPP ring group is deleted by the edge node. For example, the tenth message is used to indicate that the RRPP ring group 1 has been deleted.

In a specific implementation manner, the tenth message may be a delete ring group response message. Wherein, the delete ring group response message is used to notify the auxiliary edge node of the RRPP ring group that the edge node has deleted. For example, the message type of the delete ring group response message may be a preset type, such as delrgroupsesponse.

And D, after the auxiliary edge node receives the tenth message, deleting the RRPP ring group on the auxiliary edge node. For example, after the auxiliary edge node receives the tenth packet, the auxiliary edge node deletes the sub-ring 1, the sub-ring 2, and the sub-ring 3 from the RRPP ring group 1, and deletes the RRPP ring group 1.

In the above embodiment of the present invention, when deleting the RRPP ring group on the auxiliary edge node, even if the number of sub-rings in the RRPP ring group is large, a large impact on the device performance is not caused. Specifically, when the RRPP ring group is deleted on the auxiliary Edge node, the auxiliary Edge node only distributes the Edge-Hello packet for sending the sub-ring to each sub-ring in the RRPP ring group. Therefore, even if the Edge node still sends the Edge-Hello message to the auxiliary Edge node for each sub-ring, the auxiliary Edge node only distributes the Edge-Hello message for sending the sub-ring to each sub-ring in the RRPP ring group, thereby reducing the number of the Edge-Hello messages needing to be distributed on the auxiliary Edge node and avoiding causing impact on the performance of the equipment.
