The control-transfer separation vBRAS system comprises a control plane CP, a forwarding plane UP and a standardized interface between the CP and the UP, so the control plane CP, the forwarding plane UP and the standardized interface between the CP and the UP are also called as a CU separation VBRAS system.
Referring to fig. 1, fig. 1 is a schematic diagram of a notification path based on a UP route in the prior art shown in an exemplary embodiment, as shown in fig. 1, a CP uses a dynamic address pool or a local address pool to allocate a user address segment to a UP, a user (IP is 10.10.1.1) comes online, the CP allocates a subnet segment to the UP, the CP issues the subnet segment to the UP through a Sci entry, then the UP generates a network segment route of the user, the UP establishes a BGP adjacent relationship with a gateway device to issue the network segment route of the user, that is, the UP first issues the network segment route of the user to the UP, then the UP establishes a BGP adjacent relationship with the gateway device, and finally issues the network segment route of the user to the gateway device through the UP.
In order to solve at least the above problems in the prior art, embodiments of the present application respectively provide an exception handling method for a network element, an exception handling apparatus for a network element, an electronic device, and a computer-readable storage medium, which are described in detail below.
As shown in fig. 2, fig. 2 is a schematic diagram of a CP-based route advertisement path according to an exemplary embodiment of the present application, as shown in fig. 2, a CP adopts a dynamic address pool or a local address pool to allocate a user address segment to a UP, a user (IP is 10.10.1.1) comes online, the CP allocates a subnet segment to the UP, the CP sends a network segment route of the user to a gateway device according to a BGP temporary connection relationship established in advance with the gateway device, and simultaneously the CP sends the subnet segment to the UP through a Sci entry, so as to complete a route advertisement process, after allocating the subnet segment to the UP, the CP routes the subnet segment to the UP, and advertises the network segment route of the user to the gateway device, the two processes of routing the subnet segment route to the UP and advertising the network segment route of the user to the gateway device can be performed in parallel without routing the subnet segment to the UP first, then the UP establishes a BGP temporary connection relationship with the gateway device and sends the network segment route of the user to the gateway device, therefore, the time of the whole route advertisement can be solved, the efficiency of route announcement is improved, and the interruption of user service caused by overlong route announcement time can be avoided.
Referring to fig. 3, fig. 3 is a flowchart of a route advertisement method shown in an exemplary embodiment of the present application, where the route advertisement method provided in this embodiment is applied to a control plane network element, and the route advertisement method provided in this embodiment is applicable to a route advertisement path shown in fig. 2, as shown in fig. 3, the route advertisement method provided in this embodiment includes steps S101 to S103, and reference is made to the following detailed description:
step S101: and distributing the corresponding loopback address for the first forwarding plane network element.
The loopback address is used for creating a loopback interface for each router for the convenience of management, and an IP address is separately designated on the interface as a management address, and an administrator can remotely log in the router by using the IP address, and the IP address actually plays a role like a device name. The loopback address does not change with changes in network conditions, and represents the local virtual interface of the device, so the default is considered as an interface that is never down.
In this embodiment, a corresponding loopback address is allocated to the first forwarding plane network element, so that the first routing information is generated based on the loopback address corresponding to the first forwarding plane network element and sent to the gateway device.
Step S102: an adjacency is established with the gateway device, the adjacency conforming to the border gateway protocol.
Border Gateway Protocol (BGP) is an autonomous system routing Protocol running over TCP. BGP is the only protocol used to handle networks as large as the internet and is the only protocol that can properly handle multiple connections between unrelated routing domains. BGP builds on the experience of EGP. The main function of the BGP system is to exchange network reachability information with other BGP systems. The network reachability information includes information for listed Autonomous Systems (AS). This information effectively constructs a topology map of the AS interconnect and thus clears the routing loops, while policy decisions may be enforced at the AS level.
In this embodiment, the gateway device may be a Spine-Leaf network device, the Spine-Leaf network device is an entity device connected to a network that includes multiple virtual machines, and the forwarding plane network element may access the metropolitan area network through the Spine-Leaf network.
In this embodiment, after the adjacency relation with the gateway device is established, the route advertisement may be directly performed on the gateway device through the control plane network element.
Exemplarily, in this step, it may further be detected whether the first forwarding plane network element has already established a BGP temporary relationship with the gateway device, and if it is detected that the first forwarding plane network element has established the BGP temporary relationship with the gateway device, the BGP temporary relationship between the first forwarding plane network element and the gateway device is cut off, and the first forwarding plane network element is prevented from establishing the BGP temporary relationship with the gateway device in real time, so as to avoid that the first forwarding plane network element repeatedly notifies the gateway device of the network segment route of the user, which causes resource waste.
Step S103: and sending the first routing information to the gateway equipment based on the adjacency relation.
In this embodiment, the first routing information includes information that characterizes that a next hop of the gateway device is a loopback address corresponding to the first forwarding plane network element.
The route notification method provided by the embodiment is applied to a control plane network element, specifically, an adjacency relation is established between the control plane network element and a gateway device, and then first route information is sent to the gateway device based on the adjacency relation.
After the route advertisement is performed by the route advertisement method provided in this embodiment, in an actual internet access process of the terminal device, a data stream sequentially flows through a control plane network element, a gateway device, a first forwarding plane network element, and the terminal device.
Referring to fig. 4, fig. 4 is a flowchart of step S101 in the embodiment shown in fig. 3 in an exemplary embodiment, and as shown in fig. 4, step S101 includes steps S201 to S202, which are described in detail as follows:
step S201: and receiving an access message sent by the terminal equipment through the first forwarding plane network element.
In this embodiment, the terminal device first sends the access packet to the first forwarding plane network element, and the first forwarding plane network element sends the received access packet to the control plane network element. Illustratively, the access packet is a Point to Point Protocol Over Ethernet (PPPoE) access packet. The PPPoE access message is expanded to carry line information of the terminal equipment, such as a vendor ID, a circuit ID and the like. The PPPoE access packet is a technology for transmitting PPP (Point to Point Protocol) frame information over an ethernet. The PPPoE protocol is a mainstream Broadband access technology at present, and is widely applied to a BRAS (Broadband remote access Server). The BRAS is a novel access gateway located at the edge of the backbone network and used for completing data access of the user broadband network.
Step S202: and distributing a corresponding loopback address for the first forwarding plane network element based on the access message, and issuing the loopback address to the first forwarding plane network element.
The control plane network element receives the access message sent by the first forwarding plane network element, and indicates that the terminal device is online on the first forwarding plane network element, so that the control plane network element allocates a corresponding loopback address for the first forwarding plane network element and sends the loopback address to the first forwarding plane network element.
That is, in this embodiment, a corresponding loopback address is configured for a forwarding plane network element currently connected to a terminal device requesting to go online, and this way can distinguish the forwarding plane network element connected to the terminal device when the system includes multiple forwarding plane network elements, and further allocate a corresponding loopback address to the forwarding plane network element connected to the terminal device.
The inventor of the present application finds, through long-term research, that referring to fig. 5, fig. 5 is a schematic diagram of an advertisement path based on an UP route in the prior art, shown in fig. 5, a CP uses a dynamic address pool or a local address pool to allocate a user address segment to an UP, a user (IP is 10.10.1.1) goes online, the CP allocates a sub-network segment to an UP1, the CP issues the sub-network segment to an UP1 through a Sci entry, then the UP1 generates a network segment route of the user, the UP1 establishes a BGP1 adjacent relationship with a gateway device to issue the network segment route of the user, when an UP1 user-side interface fails, the CP notifies a UP2 that is upgraded to a main port to issue the network segment route of the user of the interface, and notifies a UP1 that is upgraded to a standby port to withdraw the network segment route of the corresponding user. And the gateway equipment learns the network segment route of the user again and finishes the route updating of the user. Compared with the situation that the whole system has only one UP, when the main UP fails, the UP main-standby switching needs to be completed firstly before the route notification is completed, so the whole route process has longer time consumption, the route notification efficiency is extremely low, and the user service interruption during the switching is easily caused.
Based on this, the present invention provides a route notification method, which is used to solve the problems that when the main UP fails, the route notification efficiency is extremely low and the user service is easily interrupted during switching.
As shown in fig. 6, fig. 6 is a schematic diagram of a CP-based route advertisement path according to an exemplary embodiment of the present application, as shown in fig. 6, a CP adopts a dynamic address pool or a local address pool to allocate a user address segment to a UP, a user (IP is 10.10.1.1) comes online, the CP allocates a sub-network segment to the UP, the CP sends a network segment route of the user to a gateway device according to a BGP temporary connection relationship established with the gateway device in advance, the next hop of the advertisement route is a loopback address of UP1, and simultaneously the CP issues the sub-network segment to UP1 through a Sci entry, so that a route advertisement process is completed, that is, after the CP allocates a sub-network segment to UP1 for UP1, the sub-network segment is routed to UP1, and the network segment route of the user is advertised to the gateway device, the two processes of UP, the UP and UP are performed in parallel without routing the sub-network segment to BGP1, and then 1 establishes a temporary connection relationship with the gateway device to send the network segment route of the user to the gateway device, therefore, the time of the whole route notification can be solved, the route notification efficiency is improved, and the interruption of user service caused by overlong route notification time can be avoided. In addition, when the user side interface of the UP1 fails, the CP notifies the gateway device that the next hop is the Loopback address of the UP2 which is raised to the active port, and notifies the gateway device that the next hop is withdrawn and lowered to the Loopback address of the standby UP 2.
Referring to fig. 7, fig. 7 is a flowchart of an exemplary route advertisement method proposed on the basis of the embodiment shown in fig. 1, as shown in fig. 7, after step S103, the route advertisement method provided in this embodiment may further include steps S301 to S303, which are described in detail as follows:
step S301: and judging whether the first forwarding plane network element has a fault.
In this embodiment, if the first forwarding plane network element fails, the terminal device connected to the first forwarding plane network element cannot communicate with the control plane network element through the first forwarding plane network element.
Exemplarily, if the failure notification information sent by the first forwarding plane network element is received, it is determined that the first forwarding plane network element fails. Illustratively, the first forwarding plane sends the failure notification information to the control plane network element when the user-side port fails. For example, the present embodiment may log in the first forwarding plane network element through the loopback address to determine whether the first forwarding plane network element fails in real time.
Referring to fig. 8, fig. 8 is a flowchart of step S301 in the embodiment shown in fig. 7 in an exemplary embodiment, and as shown in fig. 8, step S301 includes steps S401 to S402, which are described in detail as follows:
step S401: and sending the heartbeat packet to a first forwarding plane network element.
In this embodiment, the heartbeat packet is periodically sent to the first forwarding plane network element to detect the fault condition of the first forwarding plane network element in real time.
Step S402: and if the heartbeat response packet returned by the first forwarding plane network element is not received within a preset time period after the heartbeat packet is sent to the first forwarding plane network element, determining that the first forwarding plane network element fails.
In this embodiment, if the first forwarding plane network element fails, when receiving the heartbeat packet sent by the control plane network element, the first forwarding plane network element sends a heartbeat response packet to the control plane network element. In this embodiment, the size of the preset time period may be determined according to an actual application scenario, and is not specifically limited herein.
Step S302: if the judgment result is yes, the corresponding loopback address is distributed to the second forwarding surface network element.
In this embodiment, the second forwarding plane network element is a forwarding plane network element that is determined by the control plane network element from the multiple standby forwarding plane network elements and that does not currently have a fault. And after the second forwarding plane network element is determined, taking the second forwarding plane network element as a main forwarding plane network element, taking the first forwarding plane network element as a standby forwarding plane network element, and allocating a corresponding loopback address to the second forwarding plane network element.
Illustratively, the second forwarding plane network element issues an Address Resolution Protocol (ARP), and directs the traffic of the terminal device to enter, that is, directs the terminal device connected to the first forwarding plane network element to connect to the second forwarding plane network element. The ARP protocol resolves IP addresses into media access control addresses used by the LAN hardware. IP packets are often sent over ethernet, but ethernet devices do not recognize a 32-bit IP address, and they transmit ethernet packets with a 48-bit ethernet address. Therefore, the IP destination address must be translated to the ethernet destination address. In ethernet, one host must know the MAC address of the target host to communicate directly with another host. It is obtained by the address resolution protocol. The ARP protocol is used to resolve an IP address in a network into a target hardware address (MAC address) to ensure smooth communication.
Step S303: and sending the second routing information to the gateway equipment based on the adjacency relation.
In this embodiment, the second routing information includes information that characterizes a next hop of the gateway device as a loopback address corresponding to the second forwarding plane network element. The gateway device relearns the routing information about the terminal device upon receiving the second routing information.
Illustratively, because the first forwarding plane network element is reduced to the standby forwarding plane network element, the first routing information is no longer sent to the gateway device based on the adjacency relation, so as to avoid that the first routing information occupies resources such as excessive bandwidth, and in addition, confusion caused by receiving multiple routing information by the gateway device can also be avoided.
Illustratively, revocation information is sent to the gateway device based on the adjacency to cause the gateway device to revoke the first routing information.
Since the gateway device receives and stores the first routing information before receiving the second routing information, the gateway device sends revocation information to the gateway device based on the adjacency relation, so that the gateway device revokes the first routing information, that is, deletes the first routing information from the gateway device, thereby improving the accuracy of the route advertisement.
In the route advertisement method provided in this embodiment, a BGP adjacency is established between a control plane network element and a gateway device, and a network segment route of a user of a forwarding plane network element is advertised, specifically, a next hop of the advertised gateway device route is a loopback address of the forwarding plane network element currently connected to a terminal device. When the user is on line and the control plane network element allocates the network segment to the forwarding plane network element, the BGP temporary relationship is established between the control plane network element and the gateway device without establishing the BGP temporary relationship between the forwarding plane network element and the gateway device, the BGP temporary relationship is directly notified to the external device, and the next hop is the loopback address corresponding to the forwarding plane network element. When the user side interface of the forwarding plane network element fails, the control plane network element informs the gateway device that the next hop is the Loopback address of the forwarding plane network element which is upgraded to the main port, and informs the gateway device that the Loopback address of the forwarding plane network element which is upgraded to the standby forwarding plane network element is undone. By the method, when the forwarding plane network element connected with the terminal equipment fails, the route notification aiming at the network segment route of the user can be quickly executed, the route notification efficiency is improved, and the phenomenon that the user service is interrupted due to the fact that the route notification time is too long because the forwarding plane network element executes the network segment route notification of the user is avoided.
In a specific application scenario, referring to fig. 9, fig. 9 is a block diagram of a route advertisement method according to an exemplary embodiment of the present application, as shown in fig. 9, a forwarding plane network element UP1 sends notification information indicating that a user terminal CPE successfully comes on line at a forwarding plane network element UP1 to a control plane network element CP, when a user side of UP1 breaks down, a port fault information is sent to the CP, the CP updates state information of a master/backup UP, that is, the CP advertises that UP2 becomes a master CP and advertises that UP is a backup UP, and UP2 sends an ARP packet to introduce a user side traffic.
