Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
In the following description of the scheme, of the two nodes performing information interaction, the node responsible for monitoring the working connection state in the protection group or the node to which the network manager issues the switching command is referred to as a head node, and the other node is referred to as a tail node. N protection groups have the same head node and the same tail node.
Fig. 2 shows a method for implementing protection switching in an ASON control plane protection group according to the present invention, which includes the following steps
Step 201: when switching is needed, the control plane of the head node searches for an idle protection connection in the protection group, sends a time slot crossing command including all time slot crossings that the head node needs to set to the transport plane of the head node, and sends a time slot crossing request to the control plane of the tail node, and then steps 202 and 203 are respectively executed;
here, when the switching is required, it may be when the working connection in the protection group fails or after the network manager issues the switching command;
the idle protection connection means that the protection connection can protect the working connection, and specifically means that the protection connection has no fault and does not protect other working connections at this time;
the control plane of the head node stores all relevant information of all protection connections, including whether the protection connections are in an idle state or not, and the control plane of the head node can directly search the idle protection connections;
the slot crossing request includes: all the time slots that the head node needs to set are crossed.
Step 202: the transmission plane of the first node sets the time slot crossing of the first node according to the time slot crossing command;
here, the setting, by the transmission plane of the head node, the time slot crossing of the head node according to the time slot crossing command specifically includes:
the transmission plane of the first node informs a time slot crossing module of the first node according to the time slot crossing command; and the time slot crossing module of the first node sets the time slot crossing of the first node according to the time slot crossing required to be set in the time slot crossing command.
Step 203: the control plane of the tail node edits corresponding time slot crossing commands including all time slot crossings needing to be set by the tail node according to the time slot crossing requests, and issues the time slot crossing commands to the transmission plane of the tail node, and the transmission plane of the tail node sets the time slot crossings of the tail node according to the time slot crossing commands;
here, the setting, by the transmission plane of the tail node, the time slot crossing of the tail node according to the time slot crossing command specifically includes:
the transmission plane of the tail node informs a time slot crossing module of the tail node according to the time slot crossing command; and the time slot crossing module of the tail node sets the time slot crossing of the tail node according to the time slot crossing required to be set in the time slot crossing command.
After the process of setting time slot intersection by the first node is finished, the transmission plane of the first node reports the setting finished result to the control plane of the first node; after the process of setting time slot intersection by the tail node is finished, the transmission plane of the tail node reports the setting finished result to the control plane of the tail node, and after the control plane of the tail node receives the setting finished result, the control plane of the head node returns the setting finished result to the control plane of the head node;
if the control plane of the head node receives the result that the head node is successfully set and receives the result that the tail node is successfully set, the switching is successful; if the control plane of the head node receives the result that the setting of the head node fails or the result that the setting of the tail node fails, the steps 201 to 203 are executed again;
if the control plane of the head node receives the result that the setting of the head node is successful and the result that the setting of the tail node is completed is not received, continuing waiting until the result that the setting of the tail node is completed is received.
In the practical process, step 202 and step 203 are performed simultaneously, that is: the time slot cross setting of the head node and the time slot cross setting of the tail node are carried out simultaneously, the setting of the other node is not needed after the setting of the head node or the tail node is finished, and the time slot cross setting of the head node and the tail node is finished only through one command respectively, so that the time of protection switching can be shortened, and the efficiency of protection switching is improved to a certain extent.
The present invention will be described in further detail with reference to examples.
The networking schematic diagram of this embodiment is shown in fig. 3, and includes: the 3 connections form a 1:2 protection group, wherein the connection No. 1 is a working connection, and the route is A-B-C-Z; the No. 2 connection is a working connection, and the route is A-D-E-Z; the No. 3 connection is a protection connection, the route is A-Z, and the protection connection is provided with extra services; the extra traffic does not refer to traffic on other working connections being protected, and in fig. 3, the position of a may represent the position of the head node and the position of Z may represent the position of the tail node.
The method for implementing the switching process in this embodiment is shown in fig. 4, and includes the following steps:
step 401: after the first node detects that the No. 1 connection generates a multiplex section alarm, the control plane of the first node finds that the protection connection is in an idle state;
here, the control plane of the head node monitors the states of all working connections, and if the working connections are in failure, such as a multiplex section alarm, the control plane of the head node performs a protection switching process;
the control plane of the head node stores all relevant information of all protection connections, including whether the protection connections are in an idle state or not, and the control plane of the head node can directly search the idle protection connections;
the protection connection is the connection number 3.
Step 402: the control plane of the first node issues a time slot crossing command including all time slot crossings which need to be set by the first node to the transmission plane of the first node, sends a time slot crossing request to the control plane of the tail node, and then executes steps 403 and 405 respectively;
here, fig. 5 is a schematic diagram of a process of setting time slot crossing by a head node in the embodiment, as shown in fig. 5, before switching, transmission of protection services is performed on connections of 1.1 → 5.1 and 6.1 → 2.1; the transmission of the extra traffic is carried out on the connections 3.1 → 7.1 and 8.1 → 4.1;
the slot crossing command includes:
deletion 3.1 → 7.1; deletion 8.1 → 4.1; deletion 6.1 → 2.1; increase 1.1 → 7.1; increase 8.1 → 2.1; wherein, 3.1 represents the time slot No. 1 of the connection port No. 3; deletion 3.1 → 7.1 indicates: deleting the connection between 3.1 and 7.1; here, the ASON protocol specifies: when switching, the connection between the time slots in the first node sending direction is not deleted, so the time slot crossing command does not include: deletion 1.1 → 5.1; the addition of 1.1 → 7.1 and the addition of 8.1 → 2.1 indicate that the protection service transmitted on the connection No. 1 is switched to the connection No. 3 for transmission;
the setting and packaging of the time slot crossing are included in a time slot crossing command;
the time slot crossing request comprises all time slot crossings which need to be set by the first node.
Step 403: the transmitting plane of the first node informs the time slot crossing module of the first node according to the time slot crossing command, the time slot crossing module of the first node sets the time slot crossing of the first node according to the time slot crossing required to be set in the time slot crossing command, and then step 404 is executed;
here, the time slot crossing setting required to be set refers to the time slot crossing setting after being packaged in a time slot crossing command;
after deletion 3.1 → 7.1, and deletion 8.1 → 4.1, the extra traffic on the protection connection will stop running.
Step 404: after the process of setting time slot crossing by the head node is completed, the transmission plane of the head node reports the result of successful setting to the control plane of the head node, and then step 409 is executed;
here, the transport plane of the head node may also report a result of the setting failure to the control plane of the head node, and if the control plane of the head node receives the result of the setting failure, the steps 401 to 409 are re-executed.
Step 405: the control plane of the tail node edits a corresponding time slot crossing command according to the time slot crossing request, issues the time slot crossing command comprising all time slot crossings which need to be set by the tail node to the transmission plane of the tail node, and then executes step 406;
the timeslot crossing request includes all timeslot crossings that the head node needs to set, for example, delete 3.1 → 7.1, delete 8.1 → 4.1, delete 6.1 → 2.1, add 1.1 → 7.1, add 8.1 → 2.1; the tail node changes the time slot cross arrangement of the tail node according to the arrangement of the head node;
here, fig. 6 is a schematic diagram of a time slot crossing process set by a tail node in the embodiment, and as shown in fig. 6, before switching, transmission of protection traffic is performed on the connections of 9.1 → 13.1 and 10.1 → 14.1; the transmission of the extra traffic is carried out on the connections 11.1 → 15.1 and 16.1 → 12.1;
the slot crossing command includes:
deletion 9.1 → 13.1; deletion 11.1 → 15.1; deletion 16.1 → 12.1; increase 11.1 → 13.1; increase 14.1 → 12.1; here, the ASON protocol specifies: when switching is performed, the connection between the time slots in the tail node sending direction is not deleted, so that the time slot crossing command does not include: deletion 10.1 → 14.1; the addition of 11.1 → 13.1 and the addition of 14.1 → 12.1 indicate that the protection traffic transmitted on connection number 1 is switched to connection number 3 for transmission;
the time slot crossing setting is packaged and then included in the time slot crossing command.
Step 406: the transmission plane of the tail node informs the time slot crossing module of the tail node according to the time slot crossing command, the time slot crossing module of the tail node sets the time slot crossing of the tail node according to the time slot crossing required to be set in the time slot crossing command, and then step 407 is executed;
here, the time slot crossing setting required to be set refers to the time slot crossing setting after being packaged in a time slot crossing command;
after deletion 11.1 → 15.1, and deletion 16.1 → 12.1, the extra traffic on the protection connection will stop running.
Step 407: after the process of setting time slot intersection by the tail node is completed, the transmission plane of the tail node reports the result of successful setting to the control plane of the tail node, and then step 408 is executed;
here, the transport plane of the tail node may also report a result of the setting failure to the control plane of the tail node.
Step 408: after receiving the result of successful setting, the control plane of the tail node returns the result of successful setting of the tail node to the control plane of the head node, and then step 409 is executed;
here, if the control plane of the tail node receives the result of the setting failure, the result of the setting failure of the tail node is returned to the control plane of the head node, and after the control plane of the head node receives the result of the setting failure of the tail node, steps 401 to 409 are executed again.
Step 409: after receiving the successful setting results of the head node and the tail node, the control plane of the head node finishes the current processing flow;
here, if the control plane of the head node receives a result that the setting of the head node is successful and a result that the setting of the tail node is completed is not yet received, continuing to wait until a result that the setting of the tail node is completed is received;
if the control plane of the head node receives the successful setting results of the head node and the tail node, the switching is successful; after the switching is successful, the control plane of the head node can perform other operations, such as: reporting the management plane switching event, updating the protection group state and the like.
