Description
Technical Field
The present application relates to communications technologies, and in particular, to a method and a device for forwarding a packet.
Background
The ERPS (Ethernet Ring Protection Switching) is an Ethernet Ring network link layer technology with high reliability and stability. The method can prevent broadcast storm caused by the data loop when the Ethernet ring is complete, and can quickly recover the communication path between each node on the ring network when the Ethernet ring has link failure, thereby having higher convergence speed.
The user configures each device on the ERPS ring as a different node, including: master node (Owner), Neighbor (Neighbor) node, interconnect (Interconnection) node, Normal (Normal) node.
When each Link in the Ring network is normal, the ports of the master node and the neighbor nodes respectively positioned at two ends of the RPL are in a blocking state in an STP control instance to which the control VLAN belongs, each node transmits an ERPS protocol message in the control VLAN and transmits a data message in the Protection VLAN.
When a link in the ERPS Ring network fails, nodes at two ends of the failed link block a failed port, and periodically send an SF (Signal failure) RAPS (Ring Auto Protection Switching) PDU (Protocol Data Unit) message, after receiving the SF RAPS message, the master node and the neighbor node switch the STP control instance to a forwarding state and respectively release the blocked RPL ports, and forward the Data message in the Protection VLAN through the RPL, thereby completing Protection Switching of the Data message forwarding chain of the ERPS Ring network.
However, in the ERPS ring network, when the STP control instance is in the blocking state, the master node and the neighbor nodes cannot transfer the received ERPS protocol packet from the switch chip to the processor, which results in a state error of each calculated ERPS node.
Disclosure of Invention

In order to achieve the above object, the present application provides a packet forwarding method, including: the processor switches the forwarding state to the blocking state from the Spanning Tree Protocol (STP) control instance of the ring protection link RPL port, and configures an extended access control table entry for the switching chip; the priority of the expansion access control list item is higher than that of the ERPS access control list item; the switching chip maps a first ERPS protocol message which is received by the RPL port and belongs to a VLAN (virtual local area network) to an STP (spanning protocol transfer protocol) reserved example in a forwarding state based on the expansion access control list item; sending the received first ERPS protocol message to a processor in the STP reservation instance; wherein the control VLAN is associated with the STP control instance; the processor maps the received first ERPS protocol message to the STP control instance from the STP reserved instance, and sends the received first ERPS protocol message to the ERPS protocol stack.
In order to achieve the above object, the present application further provides a packet forwarding device, which at least includes a switch chip, a processor and a memory, where the processor calls a processor readable instruction of the memory to execute a setting module, an ERPS protocol driver packet receiving and sending module, and an ERPS protocol stack; the setting module is used for configuring an extended access control list item for the switching chip when the spanning tree protocol STP control instance of the RPL port of the ring protection link is switched from a forwarding state to a blocking state; the priority of the expansion access control list item is higher than that of the ERPS access control list item; the switching chip maps a first ERPS protocol message which is received by the RPL port and belongs to a VLAN (virtual local area network) to an STP (spanning protocol transfer protocol) reserved example in a forwarding state based on the expansion access control list item; sending the received first ERPS protocol message to a processor in the STP reservation instance; wherein the control VLAN is associated with the STP control instance; the ERPS drive packet receiving and sending module is used for receiving the first ERPS protocol message, mapping the first ERPS protocol message to an STP control instance from an STP reservation instance, and sending the received first ERPS protocol message to an ERPS protocol stack; and the ERPS protocol stack is used for storing the first ERPS protocol message so as to calculate the state of the STP control instance of the RPL port.
The method has the advantages that the ERPS message received in the STP control instance in the blocking state is mapped to the reserved STP instance in the forwarding state through instance mapping, so that the received ERPS protocol message is transmitted to the processor by the switching chip to calculate the state of each node of the ERPS.

A detailed description will be given of a number of examples shown in a number of figures. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present application. Well-known methods, procedures, components and circuits have not been described in detail so as not to obscure the examples.

The term "based on" means based on at least a portion thereof.
Fig. 1 is a flowchart illustrating an embodiment of a message forwarding method provided in the present application, where the method includes:
the priority of the expansion access control list item is higher than the access control list item of the ERPS.
103, the exchange chip sends the received ERPS protocol message to the processor in the STP reservation instance; wherein the control VLAN is associated with the STP control instance;
and 105, the processor sends the received ERPS protocol message to an ERPS protocol stack.
The method has the advantages that the ERPS message received in the STP control instance in the blocking state is mapped to the reserved STP instance in the forwarding state through instance mapping, so that the received ERPS protocol message is transmitted to the processor by the switching chip to calculate the state of the STP control instance of the RPL port.
In the single-ring ethernet ring shown in fig. 2A, device a is a master node, device B is a neighbor node, devices C and D are common nodes, and a link between device a and device B is an RPL link.
In the present application, on the switch chips of the device a and the device B, the STP instance may set one instance in the range of 0 to 63 as a reserved instance, such as instance 63; the processors of the device a and the device B fixedly set the STP reservation instance 63 on the switching chip to a forwarding state, and divide the reserved VLAN4095 into the STP reservation instances 63, that is, the switching chips of the device a and the device B do not reserve the ERPS protocol message of the VLAN4095 to execute STP blocking, but the data message cannot use the reserved VLAN 4095.
The message of the ERPS protocol is only one, namely RAPS PDU message, the RAPS PDU message contains ERPS ring information, and the ERPS ring information is transmitted on the ERPS ring so as to realize the intercommunication of the port information of each device.
In fig. 2A, when a link between the device C and the device D fails, the device C and the device D detect the link failure, block the failed ports C1 and D1, and periodically send an SF RAPS PDU message, after the device a and the device B receive the SF RAPS PDU message, the respective ERPS protocol stacks of the device a and the device B calculate that the state of the STP control instance of the RPL port is a forwarding state, switch the STP control instance of the respective RPL port to the forwarding state, release the RPL port a1 that was blocked before the device a releases, release the RPL port B1 that was blocked before the device B releases, switch the service between the device a and the device B to the RPL, and complete protection switching in the entire ring.
In fig. 2B, after the device C and the device D detect that the link between them is recovered, the ports C1 and D1 which were in the failure state before temporary blocking send NR RAPS PDU messages. After receiving the NR (no request) RAPS message, the device a starts a timer, blocks the RPL port a1 after the timer expires, and sends out an NR RAPS PDU message and an rb (RPL blocked) RAPS PDU message. After receiving the NR RAPS PDU message and the RB RAPS PDU message, the equipment C and the equipment D release the temporarily blocked fault recovery port; the device B blocks the RPL port B1 after receiving the NR RAPS PDU message and the RBRAPS PDU message.
In the application, the ERPS protocol stack of the device a calculates that the state of the STP control instance of the RPL port is a blocking state, blocks the RPL port a1 and switches the STP control instance from a forwarding state to the blocking state, and synchronizes the software extended ACL entry to the switching chip. After the processor of the device a synchronizes the software extended ACL entries to the hardware extended ACL entries of the switch chip, the priority of the software extended ACL entries is set to be higher than the global ERPS access control entries, so that the switch chip preferentially matches the extended ACL entries after receiving the ERPS protocol message. The ERPS protocol stack of the device B calculates that the state of the STP control instance of the RPL port is a blocking state, blocks the RPL port B1 and switches the STP control instance from a forwarding state to the blocking state, and also executes the same processing to configure an extended ACL table entry of hardware for a switching chip of the device B.
In the extended ACL entry of the switching chip of device a, the matching item (Match Field) is RPL port a1 and control VLAN, and the Action Field (Action Field) is modified to reserve VLAN4095 (remap LAN 4095) and is sent to the processor (trap CPU). In the extended ACL entry of the switching chip of the device B, the matching entry is: RPL port B1 and a control VLAN, the action item is modified to reserve VLAN4095 and is sent to the processor. The method and the device set the extended ACL list items on the basis of the RPL port, because the states of the same STP instance on different ports are not necessarily the same, and the RPL port and the control VLAN are based on to ensure that only the ERPS protocol message is matched.
For the purpose of accurately matching the ERPS protocol packet, the matching item of the extended ACL entry set for the switch chip by the processor of the device a through synchronization may be RPL port a1 and the destination mac is 0119-a700-000x, and the matching item of the extended ACL entry set for the switch chip by the processor of the device B through synchronization may be RPL port B1 and the destination mac is 0119-a700-000 x. Because the destination MAC of the ERPS protocol message is 0119-a700-000x, only the ERPS protocol message can be matched by matching the RPL port with the destination MAC address of the ERPS protocol message.
The equipment A matches the ERPS protocol message according to the expanded ACL list item, modifies the control VLAN of the ERPS protocol message into a reserved VLAN, thereby mapping the ERPS protocol message from the STP control instance to the STP reserved instance, and then sending the ERPS protocol message to the processor. The ERPS driving packet receiving and transmitting module of the processor receives the ERPS protocol message, changes the reserved VLAN4095 of the ERPS protocol message back to the control VLAN and then transmits the ERPS protocol message to the ERPS protocol stack, and the ERPS protocol stack of the device A calculates the state of the STP control instance of the RPL port A1 to be a blocking state.
And the equipment B executes the same processing according to the local extended ACL table entry, thereby mapping the ERPS protocol message from the STP control instance to the STP reservation instance and then sending the ERPS protocol message to the processor. The ERPS driving packet receiving and transmitting module of the processor receives the ERPS protocol message, changes the reserved VLAN4095 of the ERPS protocol message back to the control VLAN and then transmits the ERPS protocol message to the ERPS protocol stack, and the ERPS protocol stack of the device B calculates the state of the STP control instance of the RPL port to be a blocking state.
When the link between the device C and the device D fails again in fig. 2A, the status of the ERPS ring network is switched from fig. 2B to fig. 2A. When the device C and the device D detect a link failure, they respectively block the failed ports C1 and D1 and periodically send SF RAPS PDU messages, and after the device a and the device B respectively receive the SF RAPS PDU messages, they respectively release the blocked RPL ports a1 and B1.
The processor of device a determines that RPL port a1 is released and the STP control instance switches to a forwarding state, then notifies the switch chip to delete the extended ACL entry. The device B executes the same processing and deletes the extended ACL entry.
When receiving the ERPS protocol message through the RPL port A1, the device A sends and copies a copy to the appointed output port and sends the copy to the processor according to the ACL table entry of the general ERPS protocol message. Device B also performs the same processing, which is not described in detail.
According to the method and the device, the software scheme of the processor assists the switching chip in blocking the state of the STP control instance, and the ERPS protocol message is sent to the processor through the hardware, so that the ERPS protocol stacks of the main node and the neighbor node can normally receive and send the ERPS protocol message, and the state of the STP control instance of the RPL port is correctly calculated.

The device 30 may be used for a master node or a neighbor node in an ERPS ring network. In fig. 3, the device 30 at least includes a network interface, a switch chip, a processor and a memory, and the processor calls processor readable instructions of the memory to execute the setting module, the ERPS protocol driver packet transceiver module and the ERPS protocol stack.
