Intermediate system-to-intermediate system protocol (Intermediate System to Intermediate System, ISIS), wherein an Intermediate System (IS) refers to a router.
The technical scheme provided by the embodiment of the application can be suitable for various systems, in particular to a 5G system. For example, suitable systems may be global system for mobile communications (global system of mobile communication, GSM), code division multiple access (code division multiple access, CDMA), wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA) universal packet Radio service (general packet Radio service, GPRS), long term evolution (long term evolution, LTE), LTE frequency division duplex (frequency division duplex, FDD), LTE time division duplex (time division duplex, TDD), long term evolution-advanced (long term evolution advanced, LTE-a), universal mobile system (universal mobile telecommunication system, UMTS), worldwide interoperability for microwave access (worldwide interoperability for microwave access, wiMAX), 5G New air interface (New Radio, NR), and the like. Terminals and network devices are included in these various systems. Also included in the system are core network parts such as evolved packet system (Evloved Packet System, EPS), 5G system (5 GS), etc.
The 5G bearing network is generally composed of a dual-core route, convergence equipment and access equipment, the access equipment (generally composed of 3-4 access equipment in a ring) and the convergence equipment form a ring structure through optical cables, the equipment in the access ring can transmit data according to a preset direction, and when the ring (optical cable) is interrupted or the ring is interrupted due to equipment failure, the bearing network can rapidly reversely transmit the data of the equipment at two sides of the breakpoint from the interruption position, so that protection switching is realized, and service interruption is avoided.
In the related art, in order to realize that the access equipment is accessed to the convergence equipment nearby, the convergence equipment needs to be arranged in pairs through a physical transverse optical cable, so that the convergence equipment is excessive in quantity, a large number of slots of the convergence equipment are wasted, and the cost is high.
Fig. 1 is a schematic diagram of a bearer network according to the prior art. As shown in fig. 1, the convergence layer of the bearer network includes: sink device E1-1, sink device E2-1, sink device E3-1 and sink device E4-1, the access layer comprises: the access devices A1, A2, … access device a15, it should be understood that, in practical applications, the number of aggregation devices and access devices is not specifically limited.
In practical applications, the aggregation devices are located in aggregation machine rooms at different positions, for example, the aggregation device E1-1 is located in the aggregation machine room 1, and the aggregation device E2-1 is located in the aggregation machine room 2 …
Taking the access device a10 as an example, the closest convergence machine room is the convergence machine room 2, but the convergence machine room 2 is not provided with enough convergence devices due to the influence of the municipal road and highway trend on the access optical cable or the limitation of the investment, the machine room and other conditions, so that the access device a10 cannot access the convergence devices in the convergence machine room 2.
In one implementation, more convergence devices are required to be arranged in the convergence machine room 2 through physical transverse optical cables, and the convergence devices in the convergence machine rooms are arranged in a pair-wise overlapping manner, so that the access device A10 is accessed to the convergence devices in the convergence machine room 2 nearby.
Fig. 2 is a schematic diagram of a bearer network according to the prior art. As shown in fig. 2, 4 convergence machine rooms are taken as an example, where the convergence machine room 1 includes: the convergence equipment E1-1, the convergence equipment E1-2 and the convergence equipment E1-3, wherein the convergence equipment room 2 comprises: the convergence equipment E2-1, the convergence equipment E2-2 and the convergence equipment E2-3, wherein the convergence equipment room 3 comprises: the convergence equipment E3-1, the convergence equipment E3-2 and the convergence equipment E3-3, wherein the convergence machine room 4 comprises: sink devices E4-1, sink devices E4-2, and sink devices E4-3.
Taking the convergence equipment E1-3 and the convergence equipment E3-1 as examples, the convergence equipment E1-3 and the convergence equipment E3-1 are connected in parallel through an optical cable, the convergence equipment E1-3 is connected to the core equipment C1, the convergence equipment E3-1 is connected to the core equipment C2, the access equipment A1, the access equipment A2 and the access equipment A3 form an access loop through the convergence equipment E1-3 and the convergence equipment E3-1, when the access loop is interrupted (for example, the optical cable is interrupted or the loop is interrupted due to equipment failure), the bearing network can reversely transmit data from two sides of the breakpoint in a short time, so that protection switching is realized, and the 5G service interruption caused by open loop is prevented.
Since each convergence room cannot be 1:1 set up convergence layer equipment, this kind of setting up mode can lead to convergence equipment quantity too much, leads to convergence equipment a large amount of trench restriction, causes a large amount of wastes, and the cost is higher.
Fig. 3 is a schematic diagram of a bearer network according to the prior art. As shown in fig. 3, taking the aggregation layer including four machine rooms as an example, at least 12 aggregation devices need to be configured to implement full connection of the 4 aggregation machine rooms.
In another implementation, without adding a convergence device, the access device a10 needs to be connected to a convergence device of another machine room, please continue to refer to fig. 1, the access device a10 may be bypassed to the convergence device E3-1 in the convergence machine room 3, and similarly, the a12 cannot be connected to the E4-1 just nearby, and needs to bypass to the E1-1. However, the optical cable in this way has an excessively long path, which also results in waste of optical cable resources and has a high potential failure hazard.
In view of this, embodiments of the present application provide a bearer network, and an interrupt processing method, apparatus, and storage medium thereof. In the bearing network, the square-shaped networking is changed into double-uplink networking, and the cross-connection is used as uplink, namely, the convergence devices are respectively connected with two core devices, and in the framework, the physical cross-connection is evolved into a logic cross-connection, so that each convergence machine room is only provided with one convergence device, the number of devices is saved, and the space and electricity consumption of the convergence machine room are saved.
In addition, through the architecture, the access equipment can be accessed to the convergence equipment nearby, so that the length of an access optical cable is shortened, bypass access is avoided, the optical cable investment is saved, and the hidden trouble is greatly reduced.
It should be noted that, the above-mentioned access device may be a base station, specifically, a base station (Base Transceiver Station, BTS) and/or a base station controller in global mobile communications (Global System of Mobile communication, GSM) or code division multiple access (Code Division Multiple Access, CDMA), a base station (NodeB, NB) and/or a radio network controller (Radio Network Controller, RNC) in wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA), an evolved base station (Evolutional Node B, 4G base station or eNodeB) in long term evolution (Long Term Evolution, LTE), a relay station or access point, or a base station (5G base station) in future 5G network, etc., which are not limited herein.
The following describes in detail, with specific embodiments, a technical solution of an embodiment of the present application and how the technical solution of the present application solves the foregoing technical problems. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
Fig. 4 is a schematic diagram of a bearer network according to an embodiment of the present application. As shown in fig. 4, the bearer network includes: the access layer comprises a core layer, a convergence layer and an access layer.
The core layer comprises a first core device and a second core device, the convergence layer comprises at least two convergence devices, and the access layer comprises at least one access device.
It should be understood that, in fig. 4, the aggregation layer is illustrated by using the aggregation device E1, the aggregation device E2, the aggregation device E3, and the aggregation device E4 as examples, and the access layer is illustrated by using the access device A1 and the access device A2 … and the access device a15 as examples, and in practical application, the specific number of devices in each layer in the bearer network is not limited.
In some embodiments, each aggregation device is connected to the first core device C1 and the second core device C2, and illustratively, the aggregation device E1, the aggregation device E2, the aggregation device E3, and the aggregation device E4 are connected to the first core device C1 and the second core device C2.
Any access device aiming at the access layer is respectively accessed to the core layer through two convergence devices.
Taking access device A1, access device A2 and access device A3 as examples, one end of these access devices accesses the core layer through aggregation device E1, and the other end accesses the core layer through aggregation device E3. That is, the access device A1, the access device A2, the access device A3, the aggregation device E1, and the aggregation device E3 constitute one access loop.
It should be noted that, the construction manner of other access loops is the same as the above example, and is not described in detail here.
In the load-bearing network provided by the embodiment of the application, the physical cross connection between the convergence devices is changed into the logical cross connection, and the cross connection is used as an uplink.
Moreover, through the architecture, the access device can access nearby convergence devices without bypassing, for example, the access device A10 shown in FIG. 4 can access nearby convergence device E2, and the access device A12 can access nearby convergence device E4-1.
In some embodiments, each access loop is assigned a virtual private line service, VPWS, to implement an interior gateway protocol, IGP, closed loop for the access loop based on VPWS two-layer tunneling.
Specifically, fig. 5 is a schematic structural diagram of a bearer network according to an embodiment of the present application. It should be understood that, in the bearer network, the convergence layer includes the convergence device E1, the convergence device E2, and the convergence device E3 as an example, but in practical application, this is not limited thereto.
As shown in fig. 5, an access loop 101 is formed by a convergence device E1, a convergence device E2, an access device A1, an access device A2, and an access device A3; an access loop 102 is formed by a convergence device E1, a convergence device E2, an access device A11, an access device A12 and an access device A13; the access loop 103 is formed by the aggregation device E2, the aggregation device E3, the access device a21, the access device a22, and the access device a 23.
The convergence device in each access loop generates a cross-linked link for the access loop to realize the IGP closed loop of the access loop, and the convergence device E1 and the convergence device E2 can generate a T12-101 link for the access loop 101 and a T12-101 link for the access loop 102; sink E2 and sink E3 may generate T23-103 links for access loop 103.
The cross link is the VPWS channel.
Alternatively, each access loop is configured with a Ring-ISIS, named by the number of the access loop, e.g., access loop 101 corresponds to Ring-ISIS-101, access loop 102 corresponds to Ring-ISIS-102, and access loop 103 corresponds to Ring-ISIS-103.
The cost value of each cross link is larger than the cost value of the access loop corresponding to the cross link.
In some embodiments, each access loop in the bearer network is configured with a TI-LFA mechanism, so that when the access loop is interrupted, data on two sides of the breakpoint can be reversely transmitted from the interruption, so as to realize protection switching, and prevent the occurrence of 5G service interruption caused by open loop.
Optionally, role/location identification can be performed for each device in the bearer network in a BGP-based manner, so as to facilitate fine control of communication requirements between each device.
Exemplary, core devices may be identified AS (AS number: C role), ring attached aggregation devices may be identified AS (AS number: E role ring), 5GC attached aggregation devices may be identified AS (AS number: E role 5 GC), access devices may be identified AS (AS number: A role, AS number: ring number)
In other embodiments, the core device and the aggregation device in the bearer network have routes of all network devices, and the access device only has routes of devices in the access loop, alternatively, the access device may be routes of all networks, if the capabilities of the access device allow.
In the embodiment of the application, any aggregation device in each access loop can be configured as an inlineRR of the access loop based on a border gateway protocol BGP, so that the aggregation device is set up as an independent core RR in the loop.
In the embodiment of the application, based on the BGP protocol, enough information can be provided for the bearing network in the embodiment of the application, so that the detection of a routing loop is realized, the routing is decided according to the performance priority and the policy constraint, and the reliability of the bearing network is ensured.
In addition, as an inlineRR of the access loop, the aggregation device may allocate a neighbor-group for each access loop to reflect, and filter the routes of other access loops, so as to set a next hop as an AnycastSID, and for example, if the aggregation device E1 and the aggregation device E2 are inlineRR of the access loop 101 and the access loop 102, the neighbor-group ring101 and the neighbor-group ring102 may be generated respectively, so as to set the next hop as an A-SID-12-101 for the access loop 101 and set the next hop as an A-SID-12-102 for the access loop 102.
Any one convergence device in the access loop can be set as a target convergence device (namely, the next hop A-SID-12-101 in the access loop), so that the target convergence device is used as a main convergence device in the access loop, the access device in the access loop is accessed to the core layer, and the other convergence device is used as a standby device of the access loop, thereby reversely transmitting data at two sides of a breakpoint from the interruption position when the access loop is interrupted, and transmitting the data through the standby device.
Illustratively, taking the access loop 101 as an example, the aggregation device E1 may be configured as a target aggregation device of the access loop 101, and the aggregation device E2 may be configured as a standby device of the access loop 101.
In the embodiment of the present application, each device in each access loop may determine the reachability between each device in the access loop 101 based on the TI-LFA mechanism, and when any device is not reachable, may cancel the release of the current a-SID-12-101, and determine that the standby device in the loop is the a-SID-12-101 in the access loop 101, so as to transmit data through the standby device.
In the embodiment of the application, by configuring the TI-LFA mechanism for the access loop, the protection of links and nodes can be provided for the tunnel based on the TI-LFA mechanism, when a link or a device node at a certain position fails, the traffic can be rapidly switched to a backup path and is continuously forwarded, so that the loss of the traffic is avoided to the greatest extent, and the reliability of a bearing network is ensured.
Next, in connection with the embodiments shown in fig. 6 and fig. 7, a more detailed description will be given of an interruption processing method of the bearer network:
fig. 6 is a flowchart of an interrupt processing method of a bearer network according to an embodiment of the present application. It should be understood that the interrupt processing method provided in the embodiment of the present application is applied to the bearer network shown in fig. 4 and fig. 5, and the execution body in the embodiment of the present application may be any device in the access loop, for example, a convergence device, an access device, and so on.
Taking a first device in an access loop as a target convergence device of the access loop as an example, as shown in fig. 6, the interrupt processing method provided in the embodiment of the application includes the following steps:
s601, determining whether the access loop is interrupted based on the TI-LFA mechanism.
S602, responding to interruption of the access loop, determining that the second convergence device is a target convergence device of the access device, and reversely transmitting data at two sides of the breakpoint from the interruption position.
It should be noted that, since the TI-LFA mechanism is configured in the access loop, each device (e.g., a sink device, an access device) in the access loop may determine, in real time, an interruption situation in the access loop based on the TI-LFA mechanism, and then, a processing manner of each interruption situation will be described in more detail with reference to fig. 7:
fig. 7 is a schematic diagram of a bearer network according to an embodiment of the present application. It should be understood that, in fig. 7, the access loop 101 and the access loop 102 are taken as examples, and the interrupt processing manner of other loops is similar, which is not described herein.
As shown in fig. 7, taking the aggregation device E1 as an example of the a-SID-12-101 of the access loop 101, in a first embodiment, a link between the aggregation device and the access device may be broken, and taking, as an example, a link between the aggregation device E1 and the access device A1 is broken, the above step S602 specifically includes the following two embodiments:
(1) When the convergence device E1 responds to the interruption of the convergence device E1 and the access device A1, the convergence device E1 determines that the convergence device E2 in the access loop is a target convergence device (i.e. a-SID-12-101) based on the TI-LFA mechanism, so that the core layer sends downlink data to the access device A1 through the convergence device E2.
Specifically, when the core layer sends downlink data to the access device A1, the downlink data is first sent to the aggregation device E1, after the aggregation device E1 receives the downlink data, the downlink data is sent to the first core device C1 or the second core device C2, so that the downlink data is sent to the aggregation device E2 through the first core device C1 or the second core device C2, and then the downlink data is sent to the access device A1 through the access device A3 and the access device A2 by the aggregation device E2.
(2) When the access device A1 responds to the interruption of the aggregation device E1 and the access device A1, the access device A1 determines that the aggregation device E2 is a target aggregation device of the access loop based on the TI-LFA mechanism, and sends uplink data to the core layer through the aggregation device E2.
Specifically, when the access device A1 sends uplink data to the core layer, the access device A2 and the access device A3 send the uplink data to the aggregation device E2, so that the aggregation device E2 sends the uplink data to the core layer.
It should be noted that, the other access devices in the access loop are processed in the same manner as the access device A1, and for the access device A2 (or the access device A3), when the link between the access device A1 and the aggregation device E1 is broken, this means that the link between the access device A2 (or the access device A3) and the aggregation device E1 is broken, where the aggregation device E2 is the target aggregation device (i.e. a-SID-12-101) in the access loop 101, and when the access device A2 (or the access device A3) sends uplink data to the core layer, the uplink data is sent to the core layer through the aggregation device E2.
In a second embodiment, when at least two access devices are included in the access loop, a break in the link between the access devices may also occur. For example, please continue to refer to fig. 7, taking the access loop 101 as an example, the access device A1 is connected between the access device A2 and the aggregation device E1, where the access device A1 is an upstream device of the access device A2.
When the link between the access device A1 and the access device A2 is broken, the above step S602 specifically includes the following two embodiments:
(1) When the access device A2 responds to the interruption with the access device A1, the access device A2 determines that the aggregation device E2 is a target aggregation device (i.e. a-SID-12-101) of the access loop 101 based on the TI-LFA mechanism, and sends the uplink data to the core layer through the aggregation device E2, which should be noted that, for the access device A1, the uplink data is still sent to the core layer based on the aggregation device E1.
It should be understood that, in this access loop, if the access device A2 further includes other downlink access devices, for example, the access device A3 in fig. 7, when the access device A2 is in response to the interruption with the access device A1, the target aggregation device is the aggregation device E2, and when the access device A3 sends uplink data to the core layer, the sending needs to be performed through the aggregation device E2.
(2) The aggregation equipment E1 determines whether interruption occurs among a plurality of access equipment in an access loop based on the TI-LFA mechanism, and when the aggregation equipment E1 responds to the interruption of the plurality of access equipment in the access loop, downlink data sent by a core layer is sent to the core layer when the downlink data sent by the core layer is received, so that the core layer sends the downlink data to the access equipment through the aggregation equipment E2.
As shown in fig. 7, when an interruption occurs between access device A1 and access device A2, and/or an interruption occurs between access device A2 and access device A3, convergence device E1 stops issuing a-SID-12-101, and directs a-SID-12-101 of access loop 101 to convergence device E2 based on the TI-LFA mechanism.
When the core layer sends downlink data to the access device, the downlink data cannot reach the access device A2 and the access device A3 through the aggregation device E1 and the access device A1, so when the aggregation device E1 receives the downlink data sent by the core device, the downlink data is sent to the core device C1 or the core device C2 of the core layer first, so that the core device sends the downlink data to the access device A2 or the access device A3 through the aggregation device E2.
In a third embodiment, the link between the aggregation device and the core device may also be broken. For example, please continue to refer to fig. 7, taking the access loop 101 as an example, when the links between the aggregation device E1 and the core devices C1 and C2 are all broken, the above step S602 specifically includes the following implementation manners:
when the convergence device E1 determines that the convergence device E2 is a target convergence device of the access device based on the TI-LFA mechanism, on one hand, when the access device sends uplink data to the core layer, the uplink data is sent to the core layer through the convergence device E2.
On the other hand, when the core layer sends downlink data to the access device, the core device sends the downlink data to the access device in the access loop through the aggregation device E2.
Specifically, when the links between the aggregation device E1 and the core device C2 are all broken, the aggregation device E1 triggers conditional Anycast and stops issuing the a-SID-12-101, and directs the a-SID-12-101 of the access loop 101 to the aggregation device E2 based on the TI-LFA mechanism.
It should be noted that, when the aggregation device E1 has a link outage with one of the first core device C1 and the second core device C2, the aggregation device E1 is still kept as the target aggregation device in the access loop (i.e., the aggregation device E1 is a-SID-12-101).
For example, when the link between the aggregation device E1 and the first core device C1 is disconnected, when the access device sends uplink data to the core device, the aggregation device E1 may send the uplink data to the second core device C2 through the aggregation device E1 when receiving the uplink data sent by the access device, so as to complete transmission of the uplink data, and when the core layer sends downlink data to the access device, the aggregation device E1 may send the downlink data to the access device through the second core device C2, so that the aggregation device E1 sends the downlink data to the access device.
