Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a routing method and apparatus. Background Art

[0002] The Computing Force Network-dynamic anycast (CFN-dyncast) is a distributed technology for the computing power load and network status of multiple Mobile Edge Computing (MEC) sites, which schedules user requirements to the optimal MEC site. Since the computing power load and network status of different MEC sites are different at the same moment, therefore, how to schedule user requirements to the optimal MEC site is the core problem solved by the computing force network technology.

[0003] In the current routing method, the routing information of the Service ID (SID) and the computing power information are transmitted between Compute Force Network Routers (CFN Routers) to provide the optimal MEC site for user requirements. During the process of selecting the optimal MEC site, it is usually necessary for multiple routers on the message transmission path (such as including the Ingress Router (IR) and the Egress Router (ER)) to separately search the computing power routing table, determine the MEC site with the optimal computing power, and forward the message to the next hop. However, the computing power routing information is constantly updated and changed. The optimal MEC site found by the router according to the SID may change at different times, and the inconsistency of the MEC site may lead to a routing loop, resulting in the instability of the routing system. Summary of the Invention

[0004] The present invention provides a routing method and apparatus to improve the stability of the routing system.

[0005] In a first aspect, an embodiment of the present application provides a routing method, including: a first router receives a first data message, and determines a Binding ID (BID) corresponding to the SID according to the SID carried in the first data message and the first computing power routing information; the first router determines a corresponding target Mobile Edge Computing (MEC) site according to the BID, and sends a second data message to a second router corresponding to the target MEC site; wherein, the second data message is determined according to the first data message, and the second data message carries the BID.

[0006] According to this method, the BID can be determined based on the SID of the first data packet and the first computing power routing information, and the target MEC site can be determined according to the BID, avoiding the problem of routing loops and improving the stability of the routing system.

[0007] In a possible design, before determining the binding identifier BID corresponding to the SID according to the service identifier SID carried in the first data packet and the first computing power routing information, the first router may also receive the first computing power routing information sent by the second router, where the first computing power routing information includes the correspondence between the SID and the BID.

[0014] According to this design, the second router determines the target MEC site according to the BID of the second data packet. Also, since one BID corresponds to one MEC site, the second router can be connected to multiple MEC sites. When the number of MEC sites is fixed, the number of second routers can be reduced, the cost can be lowered, and it is also more in line with the actual computing power network application scenario.

[0033] To make the objectives, technical solutions, and advantages of the present application clearer, the following will provide a detailed and optional description of the present application in conjunction with the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0034] Next, common routing methods will be introduced.

[0035] In common routing methods, the optimal MEC site is usually found by passing the routing information and computing power information of the SID between CFN Routers. Among them, the CFN Router may include an IR and an ER. For example, the IR looks up the computing power routing table based on the SID in the data packet, finds the optimal MEC site 1, and passes the data packet to the ER. The ER finds the optimal MEC site 2 by looking up the computing power routing table based on the SID of the data packet. The ER can also convert the SID of the data packet into the corresponding BID of MEC site 2, and then send the data packet to the corresponding MEC site. However, since the computing power routing table is constantly updated and changed, the moment when the IR looks up the computing power routing table is different from the moment when the ER looks up the computing power routing table, which may result in that MEC site 1 determined by the IR through table lookup and MEC site 2 determined by the ER through table lookup are two different sites. When the optimal MEC sites are inconsistent, it may lead to routing loop problems and cause instability of the routing system.

[0036] To solve the above defects, the present application provides a routing method and device to improve the stability of the routing system.

[0037] It can be understood that a routing method provided by the present application can be executed by a first router and a second router. Among them, after obtaining the first data packet, the first router can determine the BID corresponding to the SID of the first data packet according to the SID of the first data packet and the first computing power routing information, so as to determine the corresponding target MEC site according to the BID. The first router can also send a second data packet to the second router. Among them, the second router can send a third data packet to the target MEC site according to the second data packet. Optionally, the data included in the first data packet, the second data packet, and the third data packet is the same data. In addition, the first router and the second router can be included in a computer system for executing the method shown in the present application, or can be a processing device in the computer system for executing the method shown in the present application, such as a processor or a processing module, etc., which is not specifically limited in the present application.

[0038] Figure 1 It is a schematic flowchart of a routing method provided by an embodiment of the present invention. The process may include the following steps:

[0039] S101, the first router receives the first data packet.

[0040] Exemplarily, Figure 2 For an overall architecture diagram of a realizable routing system, the first router may be Figure 2 IR1 or IR2 in. Taking Figure 2 as an example, IR1 or IR2 can obtain the first data packet from a customer edge (CE) device of the user network. The first router may also beFigure 2 IR3 in Figure 2 takes, for example, IR3 can obtain the first data packet through an Optical Line Terminal (OLT).

[0041] Optionally, the first data packet may include: data and tunnel information. For example Figure 2 as shown in packet 201 in, the tunnel information includes a Source Address (SA) and a Destination Address (DA). Among them, SA can be represented by the Internet Protocol (IP), and DA can be represented by SID. In addition, the data may include a Payload.

[0042] S102, the first router determines the BID corresponding to the SID of the first data packet according to the SID carried in the first data packet and the first computing power routing information.

[0043] Exemplarily, an SID may be carried in the first data packet. For example, an SID1 may be carried in the data packet of service 1. It can be understood that the BID corresponding to SID1 may be BID1. The SID of the first data packet may also be Figure 2 the SID2 in, then the BID corresponding to SID2 may be BID22 or BID32. The first router may select the BID corresponding to SID2 from BID22 and BID32 according to the first computing power routing information.

[0044] In one or more embodiments, before determining the binding identifier BID corresponding to the SID according to the service identifier SID carried in the first data packet and the first computing power routing information, the first router may also receive the first computing power routing information sent by the second router. Correspondingly, the second router sends the first computing power routing information to the first router. Specifically, the second router collects the first computing power routing information. For example, the first computing power routing information includes: computing power information and / or routing information. The second router may also send the first computing power routing information to the first router. Among them, in one or more embodiments, the first computing power routing information includes the correspondence between SID and BID.

[0045] Among them, the correspondence between SID and BID may be collected and / or stored by the second router. Therefore, the second router may send the correspondence between SID and BID to the first router. Exemplarily, as Figure 2 shown, the second router may be ER2. For example, SID2 corresponds to BID22, and at the same time SID2 also corresponds to BID32. ER2 may send the correspondence between SID2 and BID22, BID32 to the first router.

[0046] It is understandable that the first router determines the BID based on the SID of the first data packet and the first computing power routing information, converts the SID into the BID, and the first router converts the propagation mode of the data packet from anycast to unicast. For example, SID2 corresponds to BID22, and at the same time SID2 also corresponds to BID32. The first router determines the MEC with the optimal computing power from the MEC corresponding to BID22 and the MEC corresponding to BID32 according to the computing power, and the corresponding BID is used as the BID corresponding to the SID. Optionally, the first router may replace the SID in the first data packet with the corresponding BID.

[0047] S103. The first router determines the corresponding target MEC site according to the BID.

[0048] In this application, it is assumed that one BID corresponds to one MEC site. For example, Figure 2 the MEC site corresponding to BID32 in Figure 2 is MEC3. Another example,

[0049] the MEC site corresponding to BID22 in

[0050] is MEC2. Therefore, the first router can determine the target MEC site according to the BID.

[0051] S104. The first router sends the second data packet to the second router corresponding to the target MEC site.

[0052] In this application, the second data packet may be determined according to the first data packet. For example, the second data packet and the first data packet may carry the same data or payload. The BID may be carried in the second data packet.

[0053] As an alternative way to carry the BID, in addition to carrying the same data or payload as the first data packet, the second data packet may also carry the BID in the payload. For example, the second data packet is Figure 2 Packet 202 in, the payload in Packet 202 is the same as the payload in Packet 201. The first router can encapsulate (SA = IP1, DA = BID32) fields (or tunnel information) on the outer layer of the payload, indicating that the payload needs to be forwarded to the target MEC site corresponding to BID32. The first router can also encapsulate the payload shown in Packet 202 and the (SA = IP1, DA = BID32) fields encapsulated on the outer layer of the payload again, that is, add tunnel information (SA = IP1, DA = ER2).

[0054] Or as another alternative way to carry the BID, the second data packet may also carry the BID in the tunnel information. For example, when the first router sends the second data packet to the second router, it encapsulates the first data packet or the payload of the first data packet. The tunnel information of the encapsulated second data packet carries the BID. For example, the tunnel information carries the field (SA = IP1, DA = ER2, BID32), and the payload needs to be forwarded to the target MEC site corresponding to BID32.

[0055] Still taking Figure 2 as an example, the second data packet can be Figure 2 Packet 202 in, where the BID included in the second data packet is BID32.

[0056] Correspondingly, the second router receives the second data packet from the first router.

[0057] S105, the second router sends the third data packet to the target MEC site.

[0058] In one or more embodiments, the second router determines the target MEC site corresponding to the BID from multiple MEC sites according to the BID; the second router sends the third data packet to the target MEC site, where the third data packet is obtained according to the second data packet.

[0059] For example, as Figure 2 described, the second router can be ER2. If the second data packet is Figure 2 Packet 202 shown, then the second router can, after de-encapsulating the outer tunnel information (SA = IP1, DA = ER2) of Packet 202, use the remaining part as the third data packet, that is, Packet 203 as the third data packet. Among them, ER2 can determine the target MEC site corresponding to BID32, that is, MEC3, according to the BID32 carried in Packet 202, and ER2 sends Packet 203 to MEC3 corresponding to BID32.

[0060] It can be understood that by adopting this method, the second router determines the target MEC site according to the BID of the second data packet. Since one BID corresponds to one MEC site, the second router can be connected to multiple MEC sites. When the number of MEC sites is fixed, the number of second routers is reduced, the cost is reduced, and it is more in line with the actual computing power network application scenario.

[0061] Based on the above content and the same concept, the present application provides a routing device. As Figure 3 shown, the device includes a communication module 301 and a processing module 302.

[0062] When used to implement the first router, the communication module 301 is configured to receive a first data packet; the processing module 302 is configured to determine the binding identifier BID corresponding to the SID according to the service identifier SID carried in the first data packet and the first computing power routing information; the processing module 302 is further configured to determine the corresponding target edge computing technology MEC site according to the BID; the communication module 301 is further configured to send a second data packet to the second router corresponding to the target MEC site; wherein, the second data packet is determined according to the first data packet, and the BID is carried in the second data packet.

[0063] In a possible design, before determining the binding identifier BID corresponding to the SID according to the service identifier SID carried in the first data packet and the first computing power routing information, the communication module 301 is further configured to receive the first computing power routing information sent by the second router, wherein the first computing power routing information includes the correspondence between the SID and the BID.

[0064] When used to implement the second router, the communication module 301 is further configured to receive the second data packet sent by the first router; wherein, the BID is carried in the second data packet, and the BID is determined according to the SID of the first data packet and the first computing power routing information; the second data packet is determined according to the first data packet received by the first router; the communication module 301 is further configured to send a third data packet to the target MEC site corresponding to the BID, and the third data packet is determined according to the second data packet.

[0065] In a possible design, the communication module 301 is further configured to send the first computing power routing information to the first router, wherein the first computing power routing information includes the correspondence between the SID and the BID.

[0066] In a possible design, the processing module 302 is configured to determine the target MEC site corresponding to the BID from multiple MEC sites according to the BID;

[0067] The communication module 301 is specifically configured to: send a third data packet to the target MEC site.
