In the embodiment of the present technical solution, when a service packet is forwarded in a first path configured according to first path information of a first data page, and switching path information representing that the service packet is switched from the first path to a second path is obtained, second path information of the second data page may be configured to the service packet according to the switching path information, so that the service packet can be directly switched from the first path to the second path for forwarding.

The embodiments of the present invention will be further explained with reference to the drawings.

The system architecture platform is provided with a plurality of nodes, each node has a corresponding function, and different nodes cooperate with each other to realize the overall function of the service chain.

The system architecture platform may include a plurality of nodes, each node having a corresponding function, and different nodes cooperate with each other to implement the overall function of the service chain. In general, the multiple nodes may include a management and control system, a Network Provider Edge (NPE) disposed in a core layer, a provider edge (SPE) disposed in a convergence layer, and a user edge (UPE) disposed in an access layer.

For example, referring to fig. 1, fig. 1 is a schematic diagram of a system architecture platform for performing a path switching method according to an embodiment of the present disclosure. In fig. 1, the NPE node is NPE node 1, NPE node 2, SPE node is SPE node 1, SPE node 2, UPE node 1, UPE node 2, UPE node 3, UPE node 4, UPE node 5, UPE node 6, UPE node 7, UPE node 8, UPE node 9, UPE node 10, and UPE node 11. The management and control system is used for being connected with the SPE node 1 and the SPE node 2 respectively. The system architecture platform in fig. 1 may be applied in a Sliced Packet Network (SPN).

Referring to fig. 2, the spe node is used to perform service processing on the service packet. Generally speaking, an SPE node may be coupled to one or more UPE nodes. The SPE node may include a receiving module, a configuring module, and a data page, where the receiving module is configured to receive path information from the control system, and the configuring module may be configured to create or delete the data page, and may be further configured to configure the path information acquired by the receiving module on the data page.

It should be noted that, when there are a plurality of data pages, the specification distinguishes the first data page, the second data page, the third data page or the nth data page.

It should be noted that the number of bytes of each data page may be the same, and may be different, and the number of bytes of the data page is not specifically limited in this embodiment.

The governing system shown in fig. 1 may be a server, a host, a personal computer, an SPE node, or an end device. And the SPE node is used for forwarding the received service message to the UPE node according to the path information of the management and control system. The SPE node may be a router, a switch, or other SPE nodes, and this embodiment does not specifically limit this. The UPE node may be a router or other SPE node, and this implementation is not particularly limited thereto.

SPE nodes and UPE nodes may serve as data planes. In one embodiment, the SPE node and the UPE node may establish a tunnel, and the SPE node and the UPE node may transmit a packet through the tunnel. The tunnel may be a Virtual Extensible Local Area Network (VXLAN), a Generic Routing Encapsulation (GRE) tunnel, a mobile IP data encapsulation and tunnel (IP-in-IP), or the like.

The data plane may be controlled by the control plane. The control plane may include one or more governing systems. For example, in one embodiment, before packet transmission, the client may send attribute information of a service to the management and control system, and the management and control system may calculate to obtain path information according to the attribute information of the service sent by the client and the topology of the data plane, and then send the path information to the SPE node, so that the SPE node performs path configuration processing on the service in a tunnel to obtain a configured service packet.

It should be understood that the types of the nodes in the system architecture platform shown in fig. 1 are optional, and the types of the nodes in the system architecture platform in the embodiment of the present application may be more than those shown in fig. 1, and in this case, the system architecture platform may further include other types of nodes; alternatively, the types of the nodes in the system architecture platform may be less than those shown in fig. 1, and the embodiments of the present application do not limit the types of the nodes in the system architecture of the SFC.

It will be understood by those skilled in the art that the system architecture platform 110 may be applied to a communication network system, a mobile communication network system evolved later, and the like, and the embodiment is not limited in particular thereto.

Those skilled in the art will appreciate that the system architecture platform illustrated in FIG. 1 does not constitute a limitation on embodiments of the invention, and may include more or fewer components than those illustrated, or some components may be combined, or a different arrangement of components.

Based on the above system architecture platform, the following provides various embodiments of the path switching method of the present invention.

As shown in fig. 3, fig. 3 is a flowchart of a path switching method according to an embodiment of the present invention, where the path switching method is applied to an SPE node, and the path switching method includes, but is not limited to, step S100 and step S200.

Step S100, acquiring switching path information when the service packet is forwarded through a first path, where the first path is configured according to the first path information of the first data page.

Specifically, under the condition that the service packet is forwarded through the first path configured by the first path information of the first data page, if the management system calculates and obtains a second path with better transmission performance than that of the first path, the management system sends the switching path information to the SPE node to request the SPE node to configure the second path information of the second path with better transmission performance for the service packet.

It should be noted that the transmission performance may be obtained according to indexes such as the number of nodes passed by a path, a time delay condition of transmission of each node, a transmission rate of each node, and a load condition of each node.

It should be noted that the switching path information may indicate that, under the condition that the transmission performance of the first path is reduced, the SPE node is required to switch the service packet from the first path to the second path; the management system may also be characterized to calculate a second path with better transmission performance than the first path, and require the SPE node to update the path information in the second data page to the second path information, and then switch the service packet from the first path to the second path.

It should be noted that the switching path may be an output port of the SPE node, and may be a route between the first node and the target node, and this embodiment does not specifically limit the switching path.

Step S200, configuring the second path information of the second data page to the service message according to the switching path information, so that the service message is switched from the first path to the second path for forwarding.

Specifically, when the SPE node receives the switching path information, the second path information of the second data page may be configured to the service packet according to the switching path information, so that the service packet may be directly switched from the first path to the second path for forwarding. Because the service message is still forwarded according to the first path before switching, service change cannot be caused when second path information is configured, and all data is updated and completed when paging is switched, so that any situations such as tunnel alarm and the like cannot be caused, the service cannot be damaged, and the robustness and the continuity of the network can be ensured.

In an embodiment, when a service packet is forwarded through a first path configured by first path information of a first data page, if a management system calculates to obtain a second path with better transmission performance than that of the first path, switching path information is sent to an SPE node, and when the SPE node receives the switching path information, the SPE node may update and configure second path information in a second data page according to the switching path information, and then configure the second path information of the second data page to the service packet, so that the service packet can be directly switched from the first path to the second path for forwarding.

In an embodiment, when the service packet is forwarded through the first path configured by the first path information of the first data page, if the management system calculates that the transmission performance of the first path is lowered than that of the second path, the management system sends the switching path information to the SPE node, and when the SPE node receives the switching path information, the SPE node may configure the second path information of the second data page configured in advance to the service packet according to the switching path information, so that the service packet can be directly switched from the first path to the second path for forwarding.

In an embodiment, based on fig. 1 and fig. 2, when a service packet is forwarded in an SR tunnel by configuring a first path from first path information of a first data page, where the first path is SPE1-UPE 2-UPE3, a management and control system performs tunnel re-optimization processing to change a tunnel forwarding path of the service packet, that is, to change the tunnel forwarding path of the service packet from the first path to a second path, the management and control system may send a new path configuration to a receiving module of the first node SPE1, and after the receiving module receives configuration data (that is, second path information) of the second path, the receiving module forwards the configuration data of the second path to a configuration module, and the configuration module directly configures the configuration data of the second path to a non-service forwarding page (that is, a second data page) if the current service packet is forwarded on the first data page, the configuration data page is updated to the second data page, otherwise, the first data page is updated; after the second data page is updated, the tunnel forwarding path of the SPE node 1 is changed from the first path to a second path, wherein the second path is SPE1-UPE 8-UPE7-UPE6-UPE5-UPE4-UPE3, and before switching, the service message is still forwarded according to the first path, so that service change cannot be caused when the second path information is configured, and when paging is switched, all data are updated, so that any tunnel alarm and other situations cannot be caused, the service cannot be damaged, and the robustness and continuity of the network can be ensured.

Referring to fig. 4, the method for switching paths according to an embodiment of the present invention further includes, but is not limited to, step S410 and step S420.

Step S410, acquiring second path information;

step S420, configuring in the second data page according to the second path information, to obtain the second path information of the second data page.

In an embodiment, the SPE node receives the switch path information, where the switch path information represents that the management system calculates to obtain a second path with better transmission performance than the first path, and requires the SPE node to update the path information in the second data page to the second path information, and then when the service packet is switched from the first path to the second path, the SPE node may obtain the second path information from the management system, and update the path information in the second data page to the second path information according to the second path information to obtain the second path information of the second data page, that is, before the service packet switches the path, the SPE has configured the second path information of the second data page.

In an embodiment, before the SPE node starts to perform the path configuration on the service packet, the SPE node may receive the first path information and the second path information, at this time, the SPE node may create a first data page and a second data page according to the first path information and the second path information, configure the first path information in the first data page to obtain the first path information of the first data page, configure the second path information in the second data page to obtain the second path information of the second data page, that is, before the service packet is forwarded by the SPE node, the SPE has already configured the first path information of the first data page and the second path information of the second data page.

Referring to fig. 5, step S420 is followed by, but not limited to, step S510.

Step S510, reconfiguring in the second data page according to the second path information, and performing verification processing on the data in the second data page configured with the second path information.

Specifically, after the second data page has been configured with the second path information, the second path information may be reconfigured in the second data page, and since the second data page has been configured in step S420, data does not change between two configurations, and no traffic damage is caused, and step S510 also checks the data configured in the second data page, so as to ensure that the data in the second data page is completely correct.

Referring to fig. 6, step S200 is followed by, but not limited to, step S610 and step S620.

Step S610, obtaining third path information for configuring a third path to the service message, wherein the transmission performance of the third path is better than that of the first path;

step S620, the first path information in the first data page is updated to the third path information.

Specifically, in the process of forwarding the service packet by switching the first path to the second path through the data page switching technology, third path information for configuring a third path for the service packet is obtained from the management system, where the transmission performance of the third path is better than that of the first path, at this time, the first path information in the first data page may be updated to the third path information, and subsequently, according to the transmission performance condition of the second path, it may be decided whether to switch to the third path for forwarding, so that the service packet may be transmitted in the optimal path.

Referring to fig. 7, step S200 is followed by, but not limited to, step S710.

Step S710, when receiving the alarm information from the second path, configuring the first path information of the first data page to the service packet, so that the service packet is switched from the second path to the first path for forwarding.

Specifically, when receiving the alarm information from the second path, it indicates that the second path has a fault, and at this time, the second path cannot be used to forward the service packet, the first path information of the first data page before switching may be configured to the service packet, so that the service packet is switched from the second path to the first path to be forwarded, that is, after switching to the second data page, if the forwarding process of the service packet is abnormal or the service packet is damaged in a large amount, the second path is switched back to the first path of the first data page to be forwarded by detecting the second path alarm mechanism, thereby ensuring service continuity.

It should be noted that the alarm information is from Operation Administration and Maintenance (OAM) information, and the OAM information refers to that according to the actual needs of the network Operation of the operator, the management work of the network is generally divided into 3 categories: operation (Operation), administration (Administration), and Maintenance (Maintenance), which are abbreviated as OAM. The operation mainly completes the analysis, prediction, planning and configuration work of the daily network and the business; maintenance is mainly daily operation activities performed on the network and its service test, fault management, and the like.

Ethernet OAM is a tool for monitoring network failures, and is mainly used to solve the common link problem in the last kilometer of ethernet access. A user may monitor the link status between two point-to-point connected devices by enabling an ethernet OAM function on the two devices.

The Ethernet OAM can effectively improve the management and maintenance capacity of the Ethernet and ensure the stable operation of the network, and the main functions of the Ethernet OAM comprise:

monitoring the performance of the link: various performances of the link are monitored, including measurement of packet loss, time delay, jitter and the like, and statistics of various flows.

Fault detection and alarm: the connectivity of the link is detected by sending a detection message, and a network administrator is informed in time when the link fails.

And (3) loop test: link failures are detected by loopback of non-ethernet OAM protocol messages.

Referring to fig. 8, step S710 is followed by, but not limited to, step S810, step S820, and step S830.

Step S810, deleting the second data page and creating a third data page;

step S820, obtaining fourth path information for configuring a fourth path to the service packet, wherein the fourth path is different from the second path;

step S830, configure in the third data page according to the fourth path information, to obtain the fourth path information of the third data page.

Specifically, after the second data page has a failure problem and completes switching the service packet to the first path for forwarding, if the management system calculates to obtain a fourth path with better transmission performance than the second path, the SPE node may delete the second data page and create a third data page, then obtain, from the management system, fourth path information for configuring the fourth path to the service packet, then configure, according to the fourth path information, in the third data page to obtain the fourth path information of the third data page, and subsequently may decide, according to the transmission performance condition of the first path, whether to switch to the fourth path for forwarding, so that the service packet can be transmitted in the optimal path.

Referring to fig. 9, step S710 is followed by step S910 and step S920.

Step S910, deleting the second data page and creating a third data page;

step S920, the second path information is configured in the third data page.

Specifically, after the second data page has a failure problem and completes switching the service packet to the first path for forwarding, if the management system does not calculate another path with better transmission performance than the second path, the SPE node may delete the second data page and create a third data page, then directly configure the second path information in the third data page to obtain the second path information of the third data page, and subsequently may decide whether to switch to the second path for forwarding according to the transmission performance condition of the first path, so that the service packet may be transmitted in the optimal path.

Referring to fig. 10, before step S100, step S1010, step S1020 and step S1030 are included, but not limited thereto.

Step S1010, acquiring first path information;

step S1020, configuring in the first data page according to the first path information to obtain the first path information of the first data page;

step S1030, configuring a service packet according to the first path information of the first data page, so that the service packet is forwarded through the first path.

Specifically, when the management system receives attribute information of a service packet to be forwarded, more than two paths which meet the attribute information of the service packet may be obtained through calculation according to the attribute information and the topology of each node of the current network, then current transmission performance of the more than two paths is obtained, a first path and a second path are determined according to the current transmission performance, the first path is an optimal path in the current transmission performance, the second path is a next-optimal path in the current transmission performance, the management system may decide to forward the packet preferentially through the first path, the second path is a standby path, and the second path is used for enabling the service packet to be quickly switched to the second path for forwarding when the first path has a problem, at this time, the SPE node may obtain the first path information, then configure in the first data page according to the first path information, obtain the first path information of the first data page, and configure the service packet according to the first path information of the first data page, so that the service packet is forwarded through the first path, and the service packet can be forwarded from the optimal path.
