Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The cluster may be composed of two cluster devices to form a back-to-back cluster, one cluster device operating as a master device and the other cluster device operating as a slave device. When one of the cluster devices fails due to a failure or other reasons, the other cluster device responds to the change and starts to operate alone (as the active device). When the cluster device with power failure is restarted, the slave device needs to be added to the cluster again. In the existing processing process, both a rejoining process and a recovering process of the slave device may affect a service of the running cluster (for example, cause a service interruption of the current cluster or cause a large amount of packet loss of a service flow of the current cluster, etc.).
To facilitate understanding of the embodiment, a cluster joining method disclosed in the embodiment of the present invention is first described in detail.
Example 1
The embodiment of the invention provides a cluster joining method.
In accordance with an embodiment of the present invention, a more detailed embodiment of a cluster joining method is provided, it being noted that the steps illustrated in the flowchart of the figure may be performed in a computer system such as a set of computer-executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.
Referring to fig. 1 and fig. 2, the cluster adding method provided in this embodiment specifically includes the following steps:
first, a description is given of a cluster composition situation with reference to fig. 1, where a cluster is composed of multiple cluster devices (also referred to as a cluster Line Card frame, Line Card sessions, abbreviated as LCC), and in this embodiment, taking a cluster composed of two cluster devices as an example, each cluster device includes a main control board, multiple service Line Card boards (LPUs), and multiple network boards (also referred to as Line Card frame Switch network boards, abbreviated as SFUs). According to the difference of cluster device roles in the cluster, the two cluster devices can be mutually used as a master device and a slave device, the master device is responsible for managing and controlling the cluster while processing services, and the slave device is used as a backup device while processing services. When the master device fails, the slave device needs to be able to quickly take over the master device to process data, so as to avoid that the service in the cluster is greatly affected. Therefore, when one cluster device in the cluster fails due to a fault or other reasons, another cluster device may respond to the change and start to operate alone, and after the cluster device that has failed to fail is restarted, the restarted cluster device needs to be added to the cluster.
Step S101: and the master control board of the master device receives and responds to the joining event of the slave device.
It should be noted that the join event is a power-on restart event of the slave device or a capacity expansion join event of the slave device. The difference between the two is that the timing of the start-up is different. When the slave device is powered on and restarted, because the slave device works in the cluster mode before, after the slave device is restarted, a restart notification is sent to the master device through a control channel between the slave device and the master device, so that the original cluster is recovered with the master device. And if the two cluster devices do not form a cluster before, the two cluster devices can independently work in an in-frame forwarding mode, at the moment, workers respectively issue cluster forming instructions to the two cluster devices, the two cluster devices form a cluster, election is carried out, and the master device and the slave device are determined so as to construct a new cluster. No matter in the process of restarting or adding capacity expansion, the problem of traffic interruption or a large amount of packet loss is caused due to the smooth processing between the two cluster devices. Here, the join event is described as an example of power-on restart.
When one cluster device (for example, a slave device) fails due to a fault or other reasons, the master device responds to the change, notifies the master board to switch to the intra-frame forwarding mode through its own master control board, and starts to operate alone (that is, the service line card board of the master device receives traffic and forwards the traffic to another service line card board of its own through its own network board), at this time, the traffic received by the service line card board of the master device is not forwarded to the cluster device (that is, the slave device) that has failed, and it is ensured that the traffic can be forwarded normally.
In the process, the slave device performs power-on restart and sends a power-on restart event to the master device after the power-on restart.
The cluster comprises two cluster devices (LCC1 and LCC2) for explanation, wherein, LCC1 is used as a master device, and LCC2 is used as a slave device, when one of the cluster devices is powered down (assuming that LCC2 is powered down), only LCC1 in the cluster is still working, and the master device is LCC 1. When LCC2 is powered on and restarted, the connection with LCC1 needs to be established again.
At this time, the master control board of the LCC1 receives and responds to the power-on restart event of the LCC2, and the master control board of the LCC1 controls the smoothing process flow.
Step S102: the main control board of the main device performs the smoothing processing on each switching plane one by one until all the switching planes complete the smoothing processing.
It should be noted that, for two cluster devices forming a cluster, a switch plane and a control plane are included. One switching plane includes one screen board in the master device (also called master screen board), one screen board in the slave device (slave screen board), and a data channel formed between the master screen board and the slave screen board. One control plane includes one master control board of the master device (also referred to as master board), one master control board of the slave device (slave master board), and a control channel formed between the master control board and the slave master control board.
In view of the existence of multiple switching planes between the two LCCs (i.e., the master device and the slave device), in order to avoid traffic interruption of the cluster, the master control board of the LCC1 needs to perform smoothing on each switching plane one by one, and after the smoothing on the current switching plane is completed, perform smoothing on the next switching plane until all switching planes are completed.
The steps of the smoothing process in each switching plane are as follows:
step S1021: and setting the working mode of the main screen plate as an inter-frame exchange mode.
After the LCC2 sends a power-on restart event to the LCC1, the LCC1 switches the working mode of the master network board from the intra-frame forwarding mode to the inter-frame switching mode, so that the working modes of the slave network board and the master network board are unified and connected.
Step S1022: and opening the optical fiber interface between the master screen plate and the corresponding slave screen plate.
After the working mode conversion of the main network board is completed, the main network board automatically opens the optical fiber interface connected with the opposite-end slave network board, so that a data channel between the LCC1 and the LCC2 is communicated, the main network board and the slave network board form a switching plane through the data channel, and the flow is forwarded in a cluster mode again.
In order to effectively determine whether the connection of the optical fiber interface is correct, after the optical fiber interface between the master network board and the corresponding slave network board is opened, the method further includes:
(1) firstly, a master network board acquires a network board number and an interface number of a slave network board through a link layer protocol; and step two, comparing the screen plate number and the interface number acquired in the step one with preset connection data, judging whether the optical fiber connection is correct or not according to whether the connection data are consistent, and judging that the plane inspection state is a pass state when the comparison result is consistent.
(2) If not, namely the comparison result is inconsistent, sending out a connection error prompt message. Namely, when the comparison result is inconsistent, a connection error prompt message is given, and the plane check state is forced to be set to pass, so that the smooth processing flow of the cluster is not interrupted, and the user can perform connection adjustment after selection. Typically, for the case of LCC2 failure recovery, the link will not typically change and the link, if any, may not be resolved in a smooth process flow due to the need for fast recovery and uninterrupted recovery flow. Different from the above situation, in the smoothing process flow of adding a new cluster device into the cluster and expanding the new cluster device into the cluster, the connection line must be correct to perform the next operation.
Heretofore, when the LCC1 receives a power-on restart event of the LCC2, the LCC1 smoothes the switching planes between the LCC2 one by one, so that the planes that are not smoothed by the LCC1 can continue to operate in an intra-frame forwarding mode (that is, traffic is forwarded along another service line card of the service line card-the main network board-of the LCC 1), and the traffic is forwarded, so that the smoothing of all the switching planes is completed in this way, and the problem of traffic interruption or a large amount of packet loss caused by the fact that all the switching planes are smoothed at the same time in the prior art is avoided.
In addition, it should be noted that, no matter power-on restart or capacity expansion join is performed, the active device finally controls the cluster to perform smoothing processing. For example, in the case of power-on restart, when one cluster device loses power, another cluster device will automatically be upgraded to be the master device, and the cluster device that is power-on restarted will be considered as the slave device. Under the condition of capacity expansion joining, when two cluster devices work independently, both the two cluster devices can be regarded as main devices, when a cluster forming instruction issued by a worker is received, the two cluster devices carry out negotiation election, one cluster device is determined to be a main device according to a preset strategy, the other cluster device is determined to be a slave device, and the main device responds to a capacity expansion joining event sent by the slave device to carry out smooth processing.
Example 2
The embodiment of the invention provides a cluster joining method.
In accordance with an embodiment of the present invention, a more detailed embodiment of a cluster joining method is provided, it being noted that the steps illustrated in the flowchart of the figure may be performed in a computer system such as a set of computer-executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.
Referring to fig. 3, the cluster adding method provided in this embodiment specifically includes the following steps:
step S201: and the master control board of the master device receives and responds to the joining event of the slave device.
In this embodiment, the LCC1 is still acting as the master device and the LCC2 is acting as the slave device. This step is the same as step S101, and is not described again.
Step S202: the master device sends a first IPC message to the slave device to close all interfaces between the slave network board and the service line card board in the slave device.
Before determining the switching plane to be smoothed and starting smoothing, LCC1 sends a first Internet Process Connection (IPC) message to LCC2, and closes the interface between the slave network board and the service line card board. In implementation, the main control board of LCC1 may send the first IPC message in a multicast format. The first IPC message described above contains the destination box number (i.e., the box number of LCC2), the destination slot number (i.e., the slot numbers of all the service line cards in LCC2), and the message content. Through the first IPC message, the interfaces between all the service line cards of the LCC2 and their corresponding slave network boards are closed, so as to break down the possible problems of traffic forwarding and interruption and packet loss caused by the routing issue. Thereafter, the master board of LCC1 performs smoothing of the respective switch planes.
Step S203: the main control board of the main device performs the smoothing processing on each switching plane one by one until all the switching planes complete the smoothing processing.
The main control board of LCC1 performs smoothing on each switching plane as follows:
step S2031: and closing the flow between the service line card board of the main equipment and the main network board in the current switching plane.
The traffic interaction relationship exists between the service line card board of the LCC1 and the main board, and the specific service functions include that the main board is responsible for exchanging data, and the service line card board is responsible for data traffic processing, that is, for the LCC1, in the smoothing process, there may still be a network board where traffic passes through the smoothing process, which may also cause a problem of packet loss.
After the LCC2 joins the cluster, the master control board of the LCC1 closes the traffic between its own service line card and the master network board in the current switching plane, so as to effectively reduce the influence that the step S2032 process or the step S2033 process of the LCC2 may have on the traffic of the LCC1 when joining. The flow closing may be implemented by closing an interface on a service line card of the LCC1 or closing a main network card interface on the LCC1, which is not limited herein.
Step S2032: and setting the working mode of the main screen plate as an inter-frame exchange mode.
Step S2033: and opening the optical fiber interface between the master screen plate and the corresponding slave screen plate.
Step S2032 and step 2033 are the same as step S1021 and step S1022 described above and will not be described again.
Step S2034: and opening the flow between the service line card board and the main network board of the main equipment.
In the implementation process, after the switch plane check passes, the main control board of the LCC1 reopens the traffic between the service line card board and the main board, and the traffic can be normally forwarded between the service line card board and the main board.
Step S204: and the master equipment sends a second IPC message to the slave equipment to open the interfaces between all slave network boards and the service line card board in the slave equipment.
After all the switching planes between the LCC1 and the LCC2 are smoothed, the main control board of the LCC1 sends a second IPC message to notify all the service line cards of the LCC2 to open the interfaces to all the slave network boards, so as to open the routing issue of the LCC2, thereby realizing the normal forwarding of the cross-frame traffic, and at this point, the cluster recovery is completed, and the smoothing process flow is finished.
As can be seen from the above description, the master control board of the master device can reduce packet loss of traffic in the process of adding the slave device into the cluster by controlling the timing of closing/opening the traffic between the service line card board and the network board of the master device itself and between the service line card board and the network board of the slave device, thereby improving the reliability in the cluster forming process. The method can be suitable for the condition that the cluster equipment is added again after power failure, and the condition that new cluster equipment is added into the cluster in an expansion mode.
