Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a network device ring protection method, an apparatus thereof, and a network system.
Background
In the prior art, when some networks are deployed, link security and link redundancy are generally considered, so that the difficulties are generally encountered when designing a network topology: the network devices are directly connected by a chain, but the method has the problems that if a link between two nodes on the link fails, nodes on two sides of the two nodes cannot communicate with each other, and if a plurality of network devices are connected behind the failed link, the communication between the networks is seriously affected, so that the method has low safety. In order to solve the problem of low security in a mode of connecting network devices by using a chain, one solution in the prior art is to add another link or multiple links to some more important links, which can improve the security of the network, but in this way, a ring is formed between the devices, and broadcast data may exist among the network devices forming the ring to flood the network and occupy a large amount of network bandwidth, which may result in that normal services cannot be operated, or even completely paralysis, i.e., so-called "broadcast storm", so that there is a defect in adopting this mode.
In the prior art, a solution is also provided for a situation that a "broadcast storm" is easily generated in a ring network, that is, a ring protection Protocol is run on a network device, and a commonly used ring protection Protocol such as STP (Spanning Tree Protocol) may ensure that a ring path does not exist when a network finally reaches convergence through a Spanning Tree algorithm, and when one of links in some of the links is broken, a transmission route may be recalculated, and another link is enabled to communicate, so that a "broadcast storm" may be prevented from being formed.
When the ring Protection Protocol needs to be used, it is often necessary to perform configuration on a network device that needs to run the ring Protection Protocol and enable configuration of the Protocol on a corresponding port, but the ring Protection Protocol is not limited to one, for example, MSTP (Multiple Spanning Tree Protocol), EAPS (Ethernet Automatic Protection Switching) Protocol, and so on. Before using, however, the same ring protection protocol must be configured for each network device, and a device a configured with the MSTP protocol is added to a network deployed with EAPS, for which it is not possible to select a link using the algorithm provided by EAPS, because the network is not deployed with MSTP protocol, it is also not used with MSTP, at this time, the device a is equivalent to not being configured with the ring protection protocol. Therefore, in the prior art, the network device can only operate the ring protection protocol according to the pre-configured ring protection protocol, which causes the problem that the use of the ring protection protocol of the network device is not flexible and convenient.

Detailed Description
The present invention will be described in further detail with reference to the following detailed description and accompanying drawings.
The first embodiment is as follows:
the present embodiment provides a network device ring protection method, where the scheme of the present embodiment may relate to a sender of a protocol information packet and a receiver of the protocol information packet, please refer to fig. 1, a main process executed by the sender of the protocol information packet in the main network device ring protection method includes:
s101: acquiring a self-running ring protection protocol;
s102: packaging the information of the ring protection protocol into a protocol information message;
s103: and sending the protocol information message to the adjacent network equipment.
Common ring protection protocols, such as MSTP protocol and EAPS protocol, generally choose to use EAPS protocol for networks with fewer rings, which has the advantage of fast convergence speed. For networks with more nodes, more layers and larger networks, the MSTP protocol is often selected, but convergence is relatively slow. It can be seen that different networks have more suitable ring protection protocols for different services. In the solution in this embodiment, step S101 needs to be executed first to obtain the ring protection protocol running by itself. In a specific embodiment, the device itself may run one ring protection protocol or multiple ring protection protocols, and if the multiple ring protection protocols are run, the multiple ring protection protocols are simultaneously obtained.
In view of the fact that the final state is that each network device needs to reach the protocol convergence state, and the final purpose of acquiring the ring protection protocol running by itself is to send it to the adjacent network device, in a specific implementation manner of this embodiment, the acquisition is performed periodically or periodically. The specific time or period is flexibly set according to specific requirements. After acquiring the self-running ring protection protocol, steps S102 and S103 are sequentially executed.
After the self-running ring protection protocol is acquired, step S102 needs to be executed to encapsulate the information of these ring protection protocols, and in a specific embodiment, since the BPDU type message can be supported by most hardware devices, the BPDU type message may be sent, and the information of the self-running protocol is encapsulated according to the format specified by the type message, for example, specifically, the destination MAC address of the message is set to 01: 80: c 2: 00: 00: 00, adding a protocol type distinguishing field in a special field in the message, wherein the protocol type distinguishing field is used for characterizing the type of the protocol. So that the BPDU message can be encapsulated with the information of the ring protection protocol running by itself. Of course, it is not limited to use of BPDU-type messages for transmission, and other types of messages may be used.
Then, step S103 is executed to send the encapsulated protocol information packet to the adjacent network device, so that the adjacent network device performs corresponding protocol automatic switching, enabling, and the like according to the ring protection protocol operated by the network device.
This embodiment also provides another network device ring protection method, which mainly includes a main flow executed by a receiver of a protocol information packet in the network device ring protection method, please refer to fig. 2, where the method includes:
s201: analyzing the received protocol information message from the adjacent network equipment, and identifying the ring protection protocol operated by the adjacent network equipment;
s202: the ring protection protocol run by the adjacent network device is enabled on the self.
And analyzing the received protocol information message, wherein the protocol information message contains the status of the ring protection protocol operated by the adjacent network equipment, and identifying the status so as to know the ring protection protocol operated by the adjacent network equipment. If the adjacent network equipment uses the related protocol information sent by the BPDU-type message, the received protocol information message is the BPDU-type protocol information message, and when the protocol type is specified to be distinguished by adopting the special field in the message, the received protocol information message is analyzed, the data contained in the special field is identified, and the type of the ring protection protocol can be known according to the data. When the ring protection protocol operated by the adjacent network equipment is known, the ring protection protocol only needs to be started in the adjacent network equipment.
When the ring protection protocol performs path operation, it is the node that is concerned, and one node is connected with another node through a link, more specifically, the interaction is performed by establishing a link between ports on each node, so the ring protection protocol focuses more on the interface of the network device. In a specific implementation, a protocol type message received by a dynamic sensing port marks a corresponding port to participate in the started protocol calculation; different ring protection protocols are dynamically switched and enabled on different ports by sensing the change of protocol type messages received by the ports. Identifying the port receiving the protocol information message, and marking the port correspondingly receiving the ring protection protocol information operated by the first network equipment to participate in protocol calculation, namely using the ring protection protocol used by the adjacent network equipment to finish the operation of the link aiming at the port.
Because too frequently operating the ring protection protocol to perform calculation also occupies a large amount of bandwidth resources, and the intention of using the ring protection protocol is to select a path for communication and data transmission. If the operation is performed too frequently, the expected effect cannot be achieved, so generally, in the specific implementation, before analyzing the protocol information message sent from the adjacent network device, whether the protocol information message sent from the adjacent network device is received is further detected periodically or periodically, and when the detection result is that the protocol information message sent from the adjacent network device is received, the received protocol information message is analyzed. An executed timing period is set, and the condition of receiving the protocol information message is detected only when the period is up. Before the cycle arrives, no matter how the protocol information message of the adjacent network equipment is received, the protocol information message is analyzed only when the cycle arrives and when the received protocol information message is detected, and the following process is executed.
The present embodiment further provides another network device ring protection method, please refer to fig. 3, which includes:
s301: the first network equipment acquires a self-operated ring protection protocol and encapsulates the information of the self-operated ring protection protocol into a protocol information message; and sending the protocol information message to the second network equipment
S302: the second network equipment analyzes the received protocol information message from the first network equipment; identifying a ring protection protocol operated by the first network equipment; and the ring protection protocol run by the first network equipment is started in the self.
The flow performed by the first network device is the same as the flow illustrated in fig. 1 in the present embodiment, and the flow performed by the second network device is the same as the flow illustrated in fig. 2 in the present embodiment. The following description will be given with reference to a specific example. Suppose there are two network devices, device a and device B, which are in the same network and connected to port 2 of device B through port 1. The method comprises the steps that a device A is preset to periodically send protocol information messages to adjacent network devices, when the device A detects that a period arrives, a self-running ring protection protocol is obtained, and the device A uses an MSTP protocol; then, the device a encapsulates the operating ring protection protocol of itself as MSTP protocol into BPDU message, and sets the destination MAC address of the message to 01: 80: c 2: 00: 00: 00, the protocol type discrimination field is set to represent the corresponding data of the MSTP protocol. Then packaging the BPDU message and sending the BPDU message to the device B through the port 2; the device B receives the protocol information message and then judges whether the execution timing period arrives, and when the period arrives, the device B detects whether the protocol information message from the adjacent device is received or not; at this time, the period arrives, and then the device B detects that it has received the BPDU message from the adjacent network device a through the port 1, and then analyzes the BPDU message, mainly needs to identify the data of the protocol distinguishing field, and knows that the protocol used by the device a is the MSTP protocol, and at this time, the device B starts the MSTP protocol regardless of the protocol used by itself, and uses the MSTP protocol for the port 2. Of course, device B may also send a protocol information packet to device a, and protocol a may also enable the same protocol as device B itself, and the procedure is similar to the above procedure. The above process only aims at two network devices, and there are often many network devices in the implementation process, but the interaction process is similar to the above process. And after the protocol is completely started, setting the corresponding port and state, and restraining the broadcast storm after the protocol is converged.
By adopting the network equipment ring protection method, two ring protection protocols can be operated on the network equipment, when the port 1 of the equipment A receives the protocol message information of the equipment B, the equipment B knows that the MSTP protocol is used, the equipment A can start the MSTP protocol, and the MSTP protocol is used for calculating when the link between the equipment A and the equipment B is needed to calculate the link. The port 2 of the device a receives the protocol packet information of the device C, knows that the device C uses the EAPS protocol, and starts the EAPS protocol itself, and calculates using the EAPS protocol when the link between the device a and the device C needs to be used for calculating the link, that is, the device a uses the MSTP protocol for the port 1, and uses the EAPS protocol for the port 2. Certainly, if a specific protocol that needs to be used for configuring some preset ports is configured in advance, for example, the port 10 of the device a is configured in advance to use the EAPS protocol, even if the port 10 does not receive any protocol information message, the port 10 is also added during the operation of the EAPS. Thus, two or more ring protection protocols can be run simultaneously on device a.
The invention supports the physical topology in the network to be connected into a ring, the physical link is connected into a ring to form ring protection, in order to inhibit the broadcast storm in the ring network, firstly the invention supports two ring protection protocols, and the logical topology is calculated into a link after the protocol calculation convergence, thereby inhibiting the broadcast storm in the ring network; secondly, the port can participate in protocol calculation dynamically by sensing the opposite end protocol type dynamically on the device port, and a large amount of complicated configuration work is saved without port protocol configuration. The method can support the simultaneous operation of the dual-ring protection protocol MSTP and the EAPS protocol without conflict, simultaneously support the networking environment that other subframe single plates only support the MSTP protocol and the same type single plates support the EAPS protocol, automatically identify and switch the protocols, inhibit the broadcast storm in the ring network, and have the advantages of rapid convergence, high performance, high reliability and the like. In the above example, MSTP and EAPS protocols are mostly used for illustration, which are only used for explaining the scheme of the present invention, and do not limit the scheme of the present invention, and the scheme may be other ring protection protocols, and the same network device may support more than two ring protection protocols, and may also be more types of ring protection protocols.
Example two:
referring to fig. 4, the present embodiment provides a network device ring protection apparatus, including: an acquisition module 41, a packaging module 42, and a sending module 43; the obtaining module 41 is configured to obtain a ring protection protocol operated by itself; the encapsulating module 42 is configured to encapsulate information of a ring protection protocol running by itself into a protocol information packet; the sending module 43 is configured to send the protocol information packet to the adjacent network device through the corresponding port, so that the adjacent network device operates the corresponding ring protection protocol according to the protocol information packet.
The obtaining module 41 obtains the ring protection protocol running by itself. In a specific embodiment, the device itself may run one ring protection protocol or multiple ring protection protocols, and if the multiple ring protection protocols are run, the multiple ring protection protocols are simultaneously obtained.
In a specific embodiment of the present embodiment, the obtaining module 41 obtains the ring protection protocol periodically or periodically, considering that the final state is a state that requires each network device to reach the protocol convergence state, and the final purpose of obtaining the ring protection protocol running by itself is to send the ring protection protocol to the adjacent network device. The specific time or period is flexibly set according to specific requirements.
In a specific embodiment, since the BPDU type message can be supported by most hardware devices, the BPDU type message may be sent, and information of a protocol running by the BPDU type message is encapsulated according to a format specified by the BPDU type message, for example, specifically, a destination MAC address of the message is set to 01: 80: c 2: 00: 00: 00, adding a protocol type distinguishing field in a special field in the message, wherein the protocol type distinguishing field is used for characterizing the type of the protocol. The encapsulating module 42 can encapsulate the BPDU message with the information of the ring protection protocol running by itself. Of course, it is not limited to use of BPDU-type messages for transmission, and other types of messages may be used. Then, the sending module 43 sends the encapsulated protocol information packet to the adjacent network device, so that the adjacent network device performs corresponding protocol automatic switching, enabling, and the like according to the ring protection protocol operated by the network device. The network device ring protection apparatus 4 in this embodiment may be used to execute the network device ring protection method in fig. 1 in the first embodiment, that is, each action of the network device ring protection method in fig. 1 in the first embodiment is executed by a corresponding module in the network device ring protection apparatus. Although they may not be shown specifically.

And analyzing the received protocol information message, wherein the protocol information message contains the status of the ring protection protocol operated by the adjacent network equipment, and identifying the status so as to know the ring protection protocol operated by the adjacent network equipment. If the adjacent network device uses the related protocol information sent by the BPDU type message, the received BPDU type protocol information message is the BPDU type protocol information message, and when the protocol type is specified to be distinguished by using the special field in the message, the parsing module 51 parses the received protocol information message, identifies the data contained in the special field, and can know the type of the ring protection protocol according to the data. When the processing module 52 knows the ring protection protocol that the neighboring network device runs, it only needs to enable the ring protection protocol itself.
The processing module 52 includes an identification control sub-module 521, configured to identify a port that receives the protocol information packet, and use a ring protection protocol used by the adjacent network device for the port. When the ring protection protocol performs the open route calculation, the ring protection protocol is concerned about the nodes, and one node is connected with another node through a link, more specifically, the interaction is performed by establishing a link between ports on each node, so the ring protection protocol focuses more on the interface of the network device. In a specific embodiment, the identification control sub-module 521 identifies a port receiving the protocol information packet, and completes the operation of the link by using a ring protection protocol used by the adjacent network device for the port.
In a specific implementation manner of this embodiment, the network device ring protection apparatus 5 further includes a detection module 53. Before analyzing the protocol information packet sent by the adjacent network device, the detecting module 53 periodically or periodically detects whether the protocol information packet sent by the adjacent network device is received, and analyzes the received protocol information packet when the detecting result indicates that the protocol information packet sent by the adjacent network device is received. An execution timing period is set, and the detection module 53 detects the condition of receiving the protocol information message only when the period arrives. Before the cycle arrives, regardless of whether the protocol information message of the adjacent network device is received, the parsing module 51 performs the protocol information message parsing only if the detection module 53 detects that the protocol information message is received when the execution timing cycle arrives, and the following process. The network device ring protection apparatus 5 in this embodiment may be used to execute the network device ring protection method in fig. 2 in the first embodiment, that is, each action of the network device ring protection method in fig. 2 in the first embodiment is executed by a corresponding module in the network device ring protection apparatus.
