Detailed Description

In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

The technical means described in the embodiments of the present application may be arbitrarily combined without conflict.

In addition, in the embodiments of the present application, the terms "first", "second", and the like are used for distinguishing similar objects, and are not necessarily used for describing a particular order or sequence. The term "and/or" is merely an associative relationship that describes an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the term "at least one" means any combination of at least two of any one or more of a plurality, for example, including at least one of A, B, C, and may mean including any one or more elements selected from the group consisting of A, B and C.

A data center is a globally collaborative network of devices that is used to communicate, accelerate, present, compute, store data information over a network Internet infrastructure.

Downlink Control Information (DCI) networking of a data center needs to implement redundancy backup of a network. When any node in DCI networking has a problem, the network of all the access devices can still be ensured not to be influenced, and the DCI networking is restored to a redundant backup state after the node is repaired.

The redundancy backup of the DCI networking is usually realized by using a corresponding network protocol stack, and the DCI networking may be divided into two-layer networking and three-layer networking. Wherein, the two-layer networking runs a two-layer spanning tree protocol, and the three-layer networking runs a three-layer routing protocol. Generally, three-layer networking is used for large-scale networking, cross-network section networking and cross-server networking, and two-layer networking is used for small-scale networking and networking without cross-network section networking. Or a small two-layer network can be embedded in a large network.

In actual deployment, the two-layer networking has unique advantages, and the two-layer networking avoids complex command configuration of the three-layer networking. That is to say, when actual engineering deployment is performed, the two-layer packet network can operate without any command configuration performed by related personnel, and the two-layer packet network can be powered on. When the access device in the two-layer networking fails and needs to replace the master control disk or the service disk, the access device can be replaced at will without causing network problems.

The ports of the service tray are typically optical ports, i.e., fiber optic interfaces for connecting optical cables, while the ports of the master tray are electrical ports, i.e., ports for connecting network cables to coaxial transmission cables. When the service disk communicates with the master control disk, the switching chip needs to be configured to normally communicate. The port number of the master control disk is small, and the number of the expansion ports of the switching chip also needs to be configured. The switching chips have a cascade function, i.e. two or more switching chips can be connected to each other in a certain way. The two-layer networking is easy to realize on a single exchange chip, the realization is complex under the condition that the exchange chips are cascaded, and particularly under the condition that programs are arranged on a master control disk and a service disk and can be plugged and unplugged, the problems exist and places needing attention are many.

In the related art, when the master control disk and the service disk communicate through the cascade of the switching chips in the ring network, the risk of network storm is extremely high.

Based on this, an embodiment of the present application provides a network management method and apparatus, where first information sent by a master control disk is received through a first communication mode, and the first information represents that a setting protocol of the master control disk is in a normal operating state. And under the condition that the first information of the master control disk is not received within the set time length, adjusting the first port of the first exchange chip of the service disk to be in a first state. Wherein the first state is indicative of port blocking. And when the first port is in the first state, the first communication mode of the service disk and the master control disk is disconnected. Therefore, under the condition that the master control panel and the service panel are communicated through the cascade connection of the switching chips, and when the service panel does not receive the first information of the master control panel within the set time, the set protocol of the master control panel is considered to be in an abnormal operation state, at the moment, the service panel can adjust the first port of the first switching chip to be in a port blocking state, the first communication mode with the master control panel is disconnected, and network faults are avoided under the condition that the set protocol of the master control panel is abnormal in operation. When the network management method of the embodiment of the application is applied to the ring network and the set protocol is the ring network protocol, and the service disk does not receive the first information of the master control disk within the set time length, the ring network protocol of the master control disk is considered to be in an abnormal operation state, at this time, the service disk adjusts the first port to be in a port blocking state and disconnects the first communication mode with the master control disk, so that a network loop is prevented from being caused in the ring network, and a network storm is avoided.

The present application will be described in further detail with reference to the following drawings and examples.

Fig. 1 is a schematic diagram of an access device provided in an embodiment of the present application, as shown in fig. 1:

the access device comprises a main control disk and at least one service disk, wherein the main control disk and each service disk are provided with a central processing unit and a switching chip, and corresponding programs run on the respective central processing units. The master control disk and the service disk can be plugged and unplugged.

The second port of the second exchange chip of the master control panel is connected with the first port of the first exchange chip of each service panel, and based on the connection between the second exchange chip and the first exchange chip, the master control panel can communicate with the service panels.

Fig. 2 is a schematic view of an implementation flow of a network management method provided in an embodiment of the present application, where the method is applied to a service disk. As shown in fig. 2, the method includes:

step 201: receiving first information sent by a master control panel in a first communication mode; the first information represents that the set protocol of the master control disk is in a normal running state.

Here, in the first communication mode, the service disk and the master control disk can send and receive normal network messages to and from each other, that is, in the first communication mode, the network connection between the service disk and the master control disk is in a normal state.

The service disk receives first information sent by the master control disk through a first communication mode. The first information represents that the set protocol of the master control disk is in a normal running state.

When the access device is in the ring network, the master control panel needs to run a setting protocol, and the setting protocol is used for eliminating the physical loop of the data link layer in the local area network. Because the main control panel normally runs the setting protocol, and the setting protocol can avoid the physical loop, even if the access device is in the ring network, the network loop can not be caused, and the network storm can not be caused.

In practical applications, the setting Protocol may be Rapid Spanning Tree Protocol (RSTP). Media Access Control (MAC) addresses need to be configured for the Access device to which the master Control disk belongs, and the MAC address of the Access device and the MAC addresses of other Access devices cannot conflict with each other.

In practical application, the master control disk sends first information to the service disk circularly at regular time intervals.

Step 202: under the condition that the first information of the master control disk is not received within a set time length, adjusting a first port of a first exchange chip of the service disk to be in a first state; wherein,

Here, if the first information of the master control disk is not received within the set duration, which indicates that the set protocol of the master control disk may not be in a normal operating state, at this time, to avoid the occurrence of a network loop, the first port of the first switch chip of the service disk is adjusted to the first state, that is, the first port is adjusted to the port blocking state. And when the first port is in a port blocking state, the first communication mode of the service disk and the main control disk is disconnected. The set duration may be set to a value of 10s, 20s, 30s, and the like, and a specific value of the set duration may be set according to an actual situation, which is not limited in this embodiment of the application. It should be noted that the set time cannot be set too short, otherwise, the master control disk and the service disk will frequently communicate with each other, which brings a large load to the access device; the set time length cannot be set too large, otherwise, when the set protocol of the master control disk is in an abnormal operation state, the service disk cannot adjust the state of the first port to the first state in time, so that a network loop is caused, and a network storm is brought.

In practical application, the second port of the second switch chip of the master control panel is connected with the first port of the first switch chip of the service panel, and communication between the master control panel and the service panel is realized through cascade connection of the second switch chip and the first switch chip. The first exchange chip and the second exchange chip are respectively configured with different chip numbers.

Fig. 3 is a schematic diagram of an access device networking provided in the embodiment of the present application, as shown in fig. 3:

the access devices 1-5 are connected to the same server to form a multi-dimensional ring network topology. Each access device comprises a master control disk and at least one service disk.

In such a ring network topology, if the master controller of each access device does not operate the set protocol normally, a network storm will be caused, which not only makes each access device inaccessible, but also affects other networks. If the main control panel of each access device normally runs the set protocol, the occurrence of network storm can be avoided.

An access device runs a set protocol, the set protocol runs on a main control panel of the access device, and a central processing unit of the main control panel uniformly manages the state of a first port of a first switching chip of each service panel. When the master control disk of one access device is plugged or in an abnormal reset state, the protocol message set by the master control disk of the access device cannot be forwarded to the interconnected access devices. According to the principle of redundancy backup, when a link in a ring network topology is broken, other access devices in the network topology can sense the broken link, and then the ports included in the access devices are configured to be forwarded to a Forward state, and the access device with an abnormal master control panel cannot manage the state of the first port of the first switch chip of each service panel any more.

If the service disk does not receive the first information of the master control disk within the set time length, the state of the first port of the first exchange chip is adjusted to be a port blocking state, and the first communication mode of the master control disk and the service disk is disconnected, a network loop can be cut off, and a network storm can be avoided.

In an embodiment, before the receiving the first information sent by the master control disk through the first communication mode, the method further includes:

Here, the service disk transmits the second information to the master disk before receiving the first information transmitted from the master disk by the first communication method, and when receiving a first response of the master disk with respect to the second information, the first port is adjusted to a state corresponding to the first response. The second information represents the current state of the first port of the first exchange chip of the service disk. The first response is issued by the master disk in the event that the current state of the first port does not match the state of the first port of the master disk storage. The first response corresponds to a state of the first port of the master disk storage.

The central processing unit of the master control disk stores the state of the first port of the first switching chip of the service disk, when receiving the second information, the second information is compared with the stored state of the first port, and if the second information is not matched with the first information, a first response is sent to the service disk. And after the service disk receives the first response, the state of the first port is adjusted to be the state corresponding to the first response.

Illustratively, the second information sent by the service disk indicates that the first port is in a learning state, and the first port stored in the master control disk is in a Forward state, at this time, because the second information is not matched with the state of the first port stored in the master control disk, the master control disk sends a first response to the service disk, and the first response corresponds to the Forward state. And after receiving the first response, the service disk adjusts the state of the first port to a Forward state, so that the synchronization of the state of the first port stored in the master control disk and the state of the first port in the service disk is realized.

It should be noted that, if the state of the first port of the main control disk storage of the access device is inconsistent with the current state of the first port of the service disk, the access device may be unable to access, that is, the access device may be disconnected, and therefore, the state of the first port of the main control disk storage and the state of the first port of the service disk need to be synchronized.

In some application scenarios, the master control disk may not send the first information to the service disk in time within a set time length in a state where the protocol is set to operate normally, and at this time, the service disk adjusts the state of the first port to a blocking state, which causes the state of the first port stored in the master control disk to be inconsistent with the state of the first port of the service disk, resulting in loss of connection of the access device.

By sending the second information to the master control disk and modifying the state of the first port into the state corresponding to the first response under the condition of receiving the first response, the synchronization of the state of the first port stored in the master control disk and the state of the first port of the service disk can be realized, and the master control disk can accurately manage the state of the first port of the service disk.

In an embodiment, when the state of the first port is a first state, the service disk and the master control disk communicate in a second communication mode; when the state of the first port is a second state, the service disk and the master control disk communicate in a first communication mode;

the second response corresponds to a second state of the first port.

Here, when the first port is in the first state, that is, when the first port is in the port blocking state, the service disk communicates with the master control disk in the second communication method. When the first port is in the second state, that is, the first port is in a learning state or a forwarding state, the service disk communicates with the master control disk in the first communication mode, that is, communicates through normal network messages.

After the first port is adjusted to the first state, the service disk may send a first request to the master control disk through the second communication mode, where the first request is used to request establishment of the first communication mode with the master control disk. And under the condition that a second response of the master control disk about the first request is received, adjusting the state of the first port to the state corresponding to the second response. The second response corresponds to the second state of the first port, so that the adjusted state of the first port is the second state, and the service disk and the master control disk are communicated in the first communication mode.

It should be noted that, in the second communication mode, normal network packets cannot be transmitted and received between the master control disk and the service disk, and only Bridge Protocol Data Unit (BPDU) packets can be transmitted and received, so that the state of the first port can be adjusted according to the packet content of the BPDU packets. Therefore, the first request is a BPDU message.

In practical application, in some application scenarios, after the service disk is unplugged, the master control disk may consider the state of the first port as the first state. When the service disk is in an upgrade state or the service disk and the master control disk are disconnected in the first communication mode, the master control disk can keep the state of the first port when the service disk and the master control disk are normally communicated last time, namely, when the service disk and the master control disk are communicated in the first communication mode. When receiving a first request sent by the service disk through the second communication mode, the main control disk inquires the state of the reserved first port and returns the state of the first port to the service disk under the normal communication condition, so that the first communication mode is reestablished between the service disk and the main control disk.

By sending the first request to the master control disk and adjusting the state of the first port to the state corresponding to the second response under the condition of receiving the second response, the normal communication connection between the service disk and the master control disk can be recovered in time, so that the network state of the access device is recovered to be normal.

configuring an address forwarding table of the first switching chip; wherein,

Here, before receiving the first information sent by the master controller by the first communication method, an Address Transfer Unit (ATU) of the first switch chip is configured, and the service controller and the master controller communicate based on the Address transfer table.

Specifically, the port number of the second port of the second switch chip of the master control panel may be configured in the address forwarding table of the first switch chip, and after the configuration of the address forwarding table is completed, the BPDU message sent by the service panel is only forwarded to the second port of the second switch chip of the master control panel through the first port of the first switch chip, and is not forwarded to other ports.

The uniqueness of the flow direction of the BPDU message sent by the service disk is ensured by configuring the address forwarding table of the first switching chip, which is beneficial to ensuring the stability of the network state of the access equipment.

Fig. 4 is a schematic view of an implementation flow of a network management method provided in the embodiment of the present application, where the method is applied to a master control disk. As shown in fig. 4, the method includes:

step 401: sending first information to the service disk through a first communication mode; the first information represents that the set protocol of the master control disk is in a normal running state.

Here, the master control disk sends first information to the service disk through a first communication mode, and the first information represents that a set protocol of the master control disk is in a normal operation state.

In practical applications, the setting protocol may be RSTP. When the RSTP is configured for the master disk, the number of ports managed by the RSTP is also required to be configured, and the ports managed by the RSTP include the first port of the first switch chip of each service disk. Writing a Socket program in a central processing unit of a master control disk, receiving and transmitting a BPDU message through the Socket program, establishing a timing task through the Socket program, polling the state of a managed first port, and updating the state of the first port of the master control disk according to the state of the first port and the content of the received and transmitted BPDU message, wherein the state of the first port comprises blocking Block, Learning and Forward.

In practical application, the master control disk sends the first information to the service disk in a cycle at regular time intervals.

Step 402: under the condition that a third response of the service disk about the first information is not received within a set time length, adjusting a second port of a second exchange chip of the master control disk to be in a first state; wherein,

Here, if the first communication mode between the master control disk and the service disk is normal, after the master control disk sends the first information each time, a third response of the service disk about the first information is received, and the third response represents that the service disk successfully receives the first information.

If the third response of the service disk about the first information is not received within the set time length, which indicates that the service disk does not successfully receive the first information, at this time, a problem may possibly occur in the first communication mode between the master control disk and the service disk, and in this case, in order to avoid the generation of a network loop, the second port of the second switch chip of the master control disk is adjusted to be in the first state, that is, the port blocking state. And under the condition that the second port of the second exchange chip is in a port blocking state, the first communication mode of the main control panel and the service panel is disconnected.

It should be noted that the second port of the second switch chip of the master control panel is connected to the first port of the first switch chip of the service panel, and the communication between the master control panel and the service panel is realized through the cascade connection of the second switch chip and the first switch chip. The second exchange chip and the first exchange chip are respectively configured with different chip numbers. In practical applications, the second port of the second switch chip is also referred to as a cascade port, and the cascade port is configured in a distributed flag DSATag mode and configured with a corresponding port number. By configuring the second port of the second switching chip to the DSATag mode, when a message forwarded by the second port is received, forwarding processing can be performed only according to relevant information of DSATag in the message, so that the forwarding speed of the message is improved to the greatest extent.

In an embodiment, before the sending the first information to the service disk through the first communication mode, the method further includes:

Here, before sending the first information to the service disk through the first communication mode, the master control disk receives second information sent by the service disk, and the second information represents a current state of the first port of the first switch chip of the service disk. The central processing unit of the master control disk stores the state of the first port of the first switching chip of the service disk, when receiving the second information, the second information is compared with the stored state of the first port, and if the second information is not matched with the first information, a first response is sent to the service disk. And after the service disk receives the first response, the state of the first port is adjusted to be the state corresponding to the first response.

In an embodiment, when the state of the second port is the first state, the master control disk communicates with the service disk in a second communication mode; when the state of the second port is a second state, the master control disk and the service disk communicate in a first communication mode;

Here, when the second port is in the first state, that is, when the second port is in the port blocking state, the master and the service disks communicate with each other in the second communication method. When the second port is in the second state, that is, the first port is in the learning state or the forwarding state, the master control disk communicates with the service disk in the first communication mode, that is, communicates through a normal network message.

After the second port is adjusted to the first state, the master control disk receives a first request of the service disk through the second communication mode, and the first request is used for requesting to establish the first communication mode with the master control disk. After receiving the first request, the master control disk sends a second response about the first request to the service disk. The second response corresponds to a second state of the first port, and is used for the service disk to adjust the state of the first port to a state corresponding to the second response.

And the service disk adjusts the state of the first port to the state corresponding to the second response under the condition that the second response of the master control disk is received. The second response corresponds to the second state of the first port, so that the adjusted state of the first port is the second state, and the service disk and the master control disk are communicated in the first communication mode.

It should be noted that, in the second communication mode, the master control disk and the service disk cannot receive and transmit normal network messages, and only can receive and transmit BPDU messages, so the state of the first port can be adjusted according to the message content of the BPDU messages. Therefore, the first request is a BPDU message.

By receiving the first request of the service disk and sending the second response, the service disk adjusts the state of the first port to the state corresponding to the second response, so that the normal communication connection between the service disk and the master control disk can be timely recovered, and the network state of the access device is recovered to be normal.

configuring an address forwarding table of the second switching chip; wherein,

Before the first information is sent to the service disk through the first communication mode, an address forwarding table of the second switching chip is configured, and the service disk and the master control disk communicate based on the address forwarding table.

Specifically, the port number of the first port of the first switch chip of the service disk may be configured in the address forwarding table of the second switch chip, and after the configuration of the address forwarding table is completed, the BPDU message sent by the master control disk is only forwarded to the first port of the first switch chip of the service disk through the second port of the second switch chip, and is not forwarded to other ports. And the BPDU message received by the master control disk is only forwarded to the port connected with the central processing unit of the master control disk through the second port of the second exchange chip, and the received BPDU message is reported to the software protocol layer of the master control disk for processing.

By configuring the address forwarding table of the second switch chip, the uniqueness of the flow direction of the BPDU message received and transmitted by the master control panel is ensured, which is beneficial to ensuring the stability of the network state of the access device.
