All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

FIG. 1 is a flow diagram of a cross-domain path generation method of the present application; FIG. 2 is a schematic diagram of the cross-domain path generating apparatus of the present application; fig. 3 is a schematic structural diagram of an electronic device provided by the present application.
The embodiments of the present application provide embodiments of a cross-domain path generation method, and it should be noted that although a logic sequence is shown in the flowchart, under certain data, the steps shown or described may be accomplished in a different order than that shown or described herein.
The embodiment of the application takes the electronic equipment as an execution main body for example, and takes the path generation system as one of the expression forms of the electronic equipment, but the embodiment of the application is not limited.
Specifically, referring to fig. 1, fig. 1 is a flow chart of a cross-domain path generation method of the present application. The cross-domain path generation method provided by the embodiment of the application comprises the following steps:
step S10, a color sensing route carrying a first segment identifier is issued through a first wireless service gateway, and a first transponder and a second transponder are determined, wherein the color sensing route comprises a first base station side gateway and a color private network route;
and step S20, splicing a second segment identifier and a third segment identifier for the first segment identifier according to the first transponder and the second transponder to obtain a first routing band stack.
It should be noted that, the cross-domain path generating method in the embodiment of the present application is applied to SRv, that is, the generated cross-domain path is SRv cross-domain path. SRv6 is a new generation IP bearer protocol and can also be interpreted as segment routing based on the IPv6 forwarding plane. Further simply, SRv is sr+ipv6, SR (Segment Routing) is segment routing, IPv6 is forwarding technology, and network programmability is achieved through flexible IPv6 extension header. Further, the core idea of the SR technique is to cut the packet forwarding path into different segments, and insert segment information into the packet at the path starting point, where the intermediate node only needs to forward according to the segment information carried in the packet. Thus, the path Segment is called Segment and is identified by SID (Segment Identifier, segment identification). The SID, SRv SID, is SRv6 Segment ID, and the SRv6 SID is a 128bit value.
The first wireless service gateway RSG1 (Radio Service Gateway) issues a BGP CAR (color-aware routing) color-aware route carrying a first segment identification SID, where the first segment identification SID may be denoted as BSID0 and BGP is a border gateway protocol (Border Gateway Protocol), and the color-aware route includes a first base station side gateway and a color private network route, and thus the color-aware route may be denoted as (CSG 1, C), where CSG1 (Cell site Gate) is the first base station side gateway and C (color) is the color private network route. Further, BGP CAR color-aware routing carrying the first segment identification SID may be denoted as (CSG 1, C) band < BSID0>. Further, the BGP CAR color-aware route (CSG 1, C) carrying the first segment identification SID has a < BSID0> of SRv policy tunnel between the first wireless service gateway RSG1 and the first base station side gateway CSG1, and the SRv policy tunnel may be expressed as (endpoint: first wireless service gateway CSG1; color private network route: C; BSID: BSID 0).
Further, the path generation system needs to determine a first forwarder (PE 1) and a second forwarder (PE 3) that receive the first wireless traffic gateway RSG1 and issue a BGP CAR color-aware route carrying a first segment identification SID, determine, by the first forwarder PE1, a second segment identification SID that needs to be appended to the first segment identification SID, and determine, by the second forwarder PE3, a third segment identification SID that needs to be appended to the first segment identification SID. Then, the path generating system sequentially splices the third segment identification SID, the second segment identification SID and the first segment identification SID to obtain a first routing band stack, specifically, as described in step S201 to step S205, where the first routing band stack is the first segment identification List SID List.
Further, the descriptions of step S201 to step S205 are as follows:
step S201, determining the second segment identifier by combining the first transponder with the color perception path, and splicing the first segment identifier and the second segment identifier to obtain a routing band stack to be processed;
step S202, updating the color perception route through the to-be-processed route band stack to obtain a first updated color perception route;
step S203, the first updated color perception route is issued to the second transponder by the first transponder, and the first transponder is determined as a first issuing endpoint;
step S204, determining, by the second repeater, the third segment identifier by combining the first updated color-aware route and the first downstream endpoint;
step S205, the third segment identifier is spliced with the second segment identifier and the first segment identifier in the routing band stack to be processed in sequence, so as to obtain the first routing band stack.
Specifically, the first forwarder PE1 receives a BGP CAR color-aware route (CSG 1, C) band < BSID0> issued by the first wireless traffic gateway RSG1 and carrying a first segment identification SID, and determines a second segment identification SID between domains, which meets the intention of the color private network in the BGP CAR color-aware route to be routed by C, where the second segment identification SID may be denoted as EPE SID1. Then, the path generating system splices the first segment identification SID as BSID0 and the second segment identification SID as EPE SID1, namely, the second segment identification SID as EPE SID1 is added to the first segment identification SID as BSID0, and a routing band stack to be processed is obtained.
Further, the pending routing band stack may be represented as < EPE SID1, BSID0>, where the EPE SID binds an inter-domain specific link. The path generation system updates the BGP CAR color-aware route (CSG 1, C) band < BSID0> through the to-be-processed route band stack < EPE SID1, BSID0> to obtain a first updated BGP CAR color-aware route, wherein the first updated BGP CAR color-aware route can be expressed as (CSG 1, C) band < EPE SID1, BSID0>.
Further, the first forwarder PE1 issues the first updated BGP CAR color-aware route (CSG 1, C) with < EPE SID1, BSID0> to the second forwarder PE3 while changing the next hop to the first forwarder PE1 itself. It is further understood that, after the first forwarder PE1 issues the first updated BGP CAR color-aware route to the second forwarder PE3, the path generation system determines the first forwarder PE1 as the first downstream point.
Further, after the second forwarder PE3 receives the first updated BGP CAR color-aware route (CSG 1, C) band < EPE SID1, BSID0> issued by the first forwarder PE1, the path satisfying the intention of C in the domain is determined according to the first issuing endpoint being the first forwarder PE1 and the color private network route being C, and since the Core deployed C corresponds to FlexAlgo 128, the End SID2 belonging to FlexAlgo 128 on the egress first forwarder PE1 is determined as the third segment identification SID.
Further, the path generating system sequentially splices the third segment identification SID which is End SID2 with the second segment identification SID which is EPE SID1 and the first segment identification SID which is BSID0 in the routing band stack to be processed, namely, the third segment identification SID which is End SID2 is added to < EPE SID1 and BSID0> of the routing band stack to be processed to obtain a first routing band stack, wherein the first routing band stack can be expressed as < End SID2, EPE SID1 and BSID0>.
Further, after the path generating system obtains the first routing band stack, it is further required to update the color-aware route according to the first routing band stack, and issue the updated color-aware route to the second wireless service gateway, specifically as described in step S206 to step S207.
Step S206, updating the first updated color sensing route through the first routing band stack to obtain a second updated color sensing route;
and step S207, the second updated color perception route is issued to a second wireless service gateway through the second forwarder, and the second forwarder is determined to be a second issuing endpoint.
Specifically, the path generation system updates the first updated BGP CAR color-aware route (CSG 1, C) band < EPE SID1, BSID0> through the first route band stack < End SID2, EPE SID1, BSID0> to obtain a second updated BGP CAR color-aware route, where the second updated BGP CAR color-aware route may be represented as (CSG 1, C) band < End SID2, EPE SID1, BSID0>. Further, the second forwarder PE3 issues the second updated BGP CAR color-aware route (CSG 1, C) with < End SID2, EPE SID1, BSID0> to the second wireless traffic gateway RSG2, while changing the next hop to the second forwarder PE3 itself. It can be further understood that, after the second forwarder PE3 issues the second updated BGP CAR color-aware route (CSG 1, C) with < End SID2, EPE SID1, BSID0> to the second wireless traffic gateway RSG2, the path generation system determines the second forwarder PE3 as the second issuing endpoint.
The first routing band stack of the first SID-second SID-third SID segmentation identification List SID List can be generated by combining the color perception route, the first SID, the second SID and the third SID through the first wireless service gateway, the first base station side gateway, the first repeater and the second repeater without depending on a controller, so that the first routing band stack carrying the segmentation identification List SID List is generated on the premise of not depending on the controller.
And step S30, splicing a fourth segment identifier for the first routing band stack through the second wireless service gateway to obtain a second routing band stack.
The second wireless service gateway RSG2 receives a second updated BGP CAR color-aware route (CSG 1, C) issued by the second forwarder PE3 with < End SID2, EPE SID1, BSID0>, and determines, among the domains, a fourth segment identification SID satisfying the intention of the color private network route C in the second updated BGP CAR color-aware route. Further, the path generating system splices the fourth segment identification SID with the first routing band stack, that is, adds the fourth segment identification SID to the first routing band stack, so as to obtain a second routing band stack, specifically, as described in step S301 to step S302, where the second routing band stack is the second segment identification List SID List.
Further, the descriptions of step S301 to step S302 are as follows:
step 301, determining a fourth segment identifier by combining the second issuing endpoint and the second updated color sensing path through the second wireless service gateway;
step S302, the fourth segment identifier is spliced with the third segment identifier, the second segment identifier and the first segment identifier in the first routing band stack in sequence, so as to obtain a second routing band stack.
Specifically, the second wireless service gateway receives a second updated BGP CAR color-aware route (CSG 1, C) with < End SID2, EPE SID1, BSID0> issued by the second forwarder PE3, and determines a fourth segment identification SID satisfying the C intention among domains according to the second issuing endpoint as the second forwarder PE3, the color private network route C in the second updated BGP CAR color-aware route, where the fourth segment identification SID may be represented as the EPE SID3.
Further, the path generating system sequentially splices the fourth segment identification SID which is EPE SID3 with the third segment identification SID which is End SID2, the second segment identification SID which is EPE SID1 and the first segment identification SID which is BSID0 in the first routing band stack, namely, the fourth segment identification SID which is EPE SID3 is added to the first routing band stack < End SID2, EPE SID1 and BSID0> to obtain a second routing band stack, wherein the second routing band stack can be expressed as < EPE SID3, end SID2, EPE SID1 and BSID0>.
Further, after the path generating system obtains the second routing band stack, the path generating system further needs to update the color-aware route according to the second routing band stack, and issue the updated color-aware route to the second base station side gateway, which is specifically described in step S303 to step S304.
Step S303, updating the second updated color sensing route through the second routing band stack to obtain a third updated color sensing route;
step S304, the third updated color sensing route is issued to a second base station side gateway through the second wireless service gateway, and the second wireless service gateway is determined as a third issuing endpoint.
Specifically, the path generating system updates the second updated BGP CAR color-aware route (CSG 1, C) with < End SID2, ep SID1, BSID0> through the second routing band stack < ep SID3, end SID2, ep SID1, BSID0> to obtain a third updated BGP CAR color-aware route, where the third updated BGP CAR color-aware route may be represented as (CSG 1, C) with < ep SID3, end SID2, ep SID1, BSID0>. Further, the second wireless service gateway RSG2 issues the third updated BGP CAR color aware routing (CSG 1, C) band < EPE SID3, end SID2, EPE SID1, BSID0> to the second base station side gateway CSG2, while changing the next hop to the second wireless service gateway RSG2 itself. It can be further understood that, after the second wireless service gateway RSG2 issues the third updated BGP CAR color aware route (CSG 1, C) band < EPE SID3, end SID2, EPE SID1, BSID0> to the second base station side gateway CSG2, the path generating system determines the second wireless service gateway RSG2 as the third issuing endpoint.
The embodiment of the application can generate the second routing band stack of the first SID-second SID-third SID-fourth SID segmentation identification List SID List by combining the second wireless service gateway, the second base station side gateway and the second repeater and combining the color perception route, the first SID, the second SID, the third SID and the fourth SID without depending on a controller, thereby realizing the generation of the second routing band stack carrying the segmentation identification List SID List without depending on the controller.
And S40, splicing a fifth segment identifier for the second routing band stack through a second base station side gateway to obtain a third routing band stack.
The second base station side gateway CSG2 receives a third updated BGP CAR color aware route (CSG 1, C) band < EPE SID3, end SID2, EPE SID1, BSID0> issued by the second wireless service gateway RSG2, and determines, among the domains, a fifth segment identification SID that satisfies the intent of the color private network route C in the third updated BGP CAR color aware route (CSG 1, C) band < EPE SID3, end SID2, EPE SID1, BSID0 >. Further, the path generating system splices the fifth segment identification SID with the second routing band stack, that is, appends the fifth segment identification SID to the second routing band stack, so as to obtain a third routing band stack, specifically, as described in step S401 to step S402, where the third routing band stack is the third segment identification List SID List.
Further, the descriptions of step S401 to step S402 are as follows:
step S401, determining a fifth segment identifier by combining the third issuing endpoint and the third updated color sensing path through the second base station side gateway;
step S402, sequentially splicing the fifth segment identifier with the fourth segment identifier, the third segment identifier, the second segment identifier and the first segment identifier in the second routing band stack, so as to obtain a third routing band stack.
Specifically, the second base station side gateway CSG2 receives a third updated BGP CAR color aware route (CSG 1, C) with < EPE SID3, end SID2, EPE SID1, BSID0> issued by the second wireless service gateway RSG2, and determines a fifth segment identification SID satisfying the C intention among domains according to a third issuing endpoint issued by the second wireless service gateway RSG2, wherein the fifth segment identification SID may be denoted as BSID4, with a color private network route C among < EPE SID3, end SID2, EPE SID1, BSID0>. Further, the path generating system sequentially splices the fifth segment identification SID with the fourth segment identification SID of the second routing band stack being the EPE SID3, the third segment identification SID being the End SID2, the second segment identification SID being the EPE SID1 and the first segment identification SID being the BSID0, namely, adds the fifth segment identification SID of the BSID4 to the second routing band stack < EPE SID3, end SID2, EPE SID1, BSID0> to obtain a third routing band stack, wherein the third routing band stack can be expressed as < BSID4, EPE SID3, end SID2, EPE SID1, BSID0>.
The embodiment of the application combines the second wireless service gateway and the second base station side gateway with the color perception route, the first SID, the second SID, the third SID, the fourth SID and the fifth SID to generate the third route band stack of the first SID-second SID-third SID-fourth SID-fifth SID segment identification List SID List without depending on a controller, thereby realizing the generation of the third route band stack carrying the segment identification List SID List without depending on the controller.
Step S50, generating a cross-domain path based on the third routing band stack, the first base station side gateway, the second base station side gateway and the color private network route.
The path generation system gives corresponding coloring information to the color private network route C according to the first base station side gateway CSG1 and the second base station side gateway CSG 2. Next, the path generation system associates the third routing band stack < BSID4, EPE SID3, end SID2, EPE SID1, BSID0> with the coloring information of the color private network route C to generate a cross-domain SRv path. Finally, the path generation system introduces the private network traffic into the SRv path in a cross-domain manner on the forwarding plane, so as to complete the cross-domain forwarding between the first wireless service gateway RSG1 and the second wireless service gateway RSG2, specifically as described in step S501 to step S503.
Further, the descriptions of step S501 to step S503 are as follows:
step S501, determining virtual network services of the first base station side gateway and the second base station side gateway;
step S502, determining target coloring information of the color private network route according to the service demand in the virtual network service;
step S503, after detecting, by the second base station side gateway, a private network route carrying the target coloring information, associating, by the first base station side gateway and the target coloring information, the third routing band stack, and generating the cross-domain path.
Specifically, an end-to-end VPN service (virtual network service) is deployed between the first base station side gateway CSG1 and the second base station side gateway CSG2, and therefore, the path generation system first needs to determine the virtual network service between the first base station side gateway CSG1 and the second base station side gateway CSG 2. Then, the path generating system determines the service requirement in the virtual network service, and determines the target coloring information of the Color private network route C according to the service requirement in the virtual network service, and in an embodiment, the target coloring information of the Color private network route C is Color C1 if the service requirement corresponds to Color C1. Further, the second base station side gateway CSG2 performs a sensing detection on each private network route, if the sensing detection carries a private network route with target coloring information being Color C1, the second base station side gateway CSG2 associates a third routing band stack < BSID4, EPE SID3, end SID2, EPE SID1, BSID0> with the target coloring information Color C1 according to BGP next hop, i.e. learns BGP CAR Color sensing routes (CSG 1, C) band < BSID4, EPE SID3, end SID2, EPE SID1, BSID0>, and generates a cross-domain SRv path. Finally, the path generation system introduces private network traffic into SRv paths in a cross-domain manner on a forwarding plane, namely encapsulates corresponding SIDs List, and completes cross-domain forwarding between the first wireless service gateway RSG1 and the second wireless service gateway RSG 2.
