Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
The network architecture and the service scenario described in the embodiment of the present invention are for more clearly illustrating the technical solution of the embodiment of the present invention, and do not form a limitation on the technical solution provided in the embodiment of the present invention, and it can be known by those skilled in the art that the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems along with the evolution of the network architecture and the appearance of a new service scenario.
As shown in fig. 1a, the vBNG and the network device 2 are interconnected by at least two links (e.g., link 1 and link 2), and the vBNG receives user-side routing information from the network device 3 through the interface 1, the routing information includes IP address information of the user device 1, the IP address information may be an IP address such as 10.1.1.1, or IP address prefix information such as 10.1.1.0, or an IP address plus a subnet mask such as 10.1.1.1/24. The virtual network device runs an Interior Gateway Protocol (IGP) routing Protocol process, for example, the IGP may be an Open Shortest Path First (OSPF), an Intermediate System-to-Intermediate System (IS-IS), or the like. After receiving the routing information from the user side, the vBNG issues the routing information from the interface 2 and the interface 4 through the IGP process, respectively. The network device 2 receives the routing information from the interface 5 and the interface 6, respectively, and generates two forwarding entries, where the destination IP address information of the two forwarding entries is the IP address information of the user device 1, and the output interfaces are the interface 5 and the interface 6, respectively. For example, when the cost (english: cost) value of the link 2 is lower than the cost value of the link 1, the forwarding table entry of the egress interface, i.e. the interface 6, is selected, and the data packet is forwarded to the ue 1. After the vBNG receives the data packet addressed to the user equipment 1 from the interface 4, the data packet needs to pass through the switching network, and is sent from the forwarding unit 2 to the forwarding unit 1, and the data packet is sent from the interface 1 of the forwarding unit 1. It should be noted that such forwarding that needs to be performed across a switching network may be referred to as board-crossing forwarding, forwarding across a forwarding unit, or VM-crossing forwarding, and the like, and the corresponding data stream may be referred to as board-crossing forwarding data stream, forwarding across a forwarding unit, or VM-crossing forwarding data stream.
Since vBNG is a software process that replaces a hardware (e.g., chip) process, performance is relatively poor. In particular, when forwarding of data messages within the vBNG requires passing through the switching network, the forwarding performance of the vBNG is further degraded.
The switching network may be a hardware switch or a software virtual switch. The network device 2 may be a physical hardware network device, such as a router or a switch, or may be a virtual network device based on the NFV technology, such as a virtual router or a virtual switch. The User Equipment (UE) may include various handheld devices, vehicle-mounted devices, wearable devices, computer devices or other processing devices connected to a wireless modem with wireless communication functions, as well as various forms of User Equipment, Mobile Stations (MS), terminals (Terminal), Terminal devices (TE), and so on. For convenience of description, the above-mentioned devices are collectively referred to as user equipment or UE in this application.
Based on the application scenario described in fig. 1a, fig. 2 is a schematic flowchart of a method for routing and publishing according to an embodiment of the present invention. The method is applied to a vBNG (as a first network device), where the first network device is connected to a second network device via two links, and the first network device includes at least two forwarding units, at least one control unit, and at least one switching unit (also called a switching network). Wherein the at least two forwarding units comprise a first forwarding unit and a second forwarding unit. And the first network equipment and the second network equipment operate an IGP protocol and establish an IGP neighbor relation between the first network equipment and the second network equipment, and the IGP neighbor relation is in an IGP domain.
The scheme provided by the embodiment of the invention is explained in the following with reference to the attached figure 2.
The scheme provided by the embodiment of the invention comprises a part 201, a part 302 and a part 203, which are respectively explained below.
At element 201, the first network device creates at least two routing protocol processes, wherein one routing protocol process is associated with one forwarding unit, and the at least two routing protocol processes include a first routing protocol process and a second routing protocol process. The routing protocol process may be an IGP routing protocol process such as an OSPF process, an IS-IS process, or the like.
And creating a third routing protocol process on the second network equipment, and respectively establishing an IGP (integrated gate protocol) neighbor relation between the third routing protocol process and the first routing protocol process and the second routing protocol process on the first network equipment. Alternatively, a third routing protocol process and a fourth routing protocol process may be created on the second network device, where the third routing protocol process may establish an IGP neighbor relationship with the first routing protocol process on the first network device, and the fourth routing protocol process may establish an IGP neighbor relationship with the second routing protocol process on the first network device.
At element 202, the first network device associates the first routing protocol process with the first forwarding unit and associates the second routing protocol process with the second forwarding unit.
Associating the first routing protocol process with the first forwarding unit may be understood as that the first routing protocol process is only responsible for issuing (also called announcing) routing information received from an interface of the first forwarding unit that is not joined to the first routing protocol process, from an interface of the first forwarding unit that is joined to the first routing protocol process. For example, as shown in fig. 1a, the first routing protocol process (e.g., ospf process 1) is created at the control element of the vBNG, and interface 2 (which is an interface connected to the network-side network device) joins ospf1 (specifically, for example, joining ospf process 1 may be implemented by joining an IP address configured on interface 2 to ospf1, or enabling ospf capability on interface 2). The vBNG receives the message from the user equipment 1 from the interface 1 (which is an interface connected to the user side equipment and is not added to the ospf process 1), obtains the IP address information of the user equipment 1, and introduces the IP address information as routing information to the ospf process 1. The routing information of the user equipment 1 is published from the interface 2 to the network equipment 2 via the ospf process 1. It should be understood that the interface 2 is a network-side interface, the interface 1 is a user-side interface, there may be a plurality of interfaces 2, and there may also be a plurality of interfaces 1, and each of these interfaces is only illustrated by one interface, but is not limited thereto.
Specifically, the first network device may associate the first routing protocol process with the first forwarding unit in the following two ways.
In a first manner, the first network device directly introduces, by default, the routing information of the user terminal side received from the first interface of the first forwarding unit into the first routing protocol process, and the first routing protocol process issues the routing information from the second interface of the first forwarding unit to the second network device. The method is directly encoded and realized in software in the product development process of the first network equipment, and subsequent manual configuration operation is not needed to participate in realization.
And in a second mode, the first network device instructs the first forwarding unit to set a first flag for the routing information received from the first interface, and introduces the routing information with the first flag into the first routing protocol process for issuing.
Optionally, setting the first flag may be implemented on the first network device by a configuration command. For example, a command line that instructs a user network side route (unr) received on slot1 (i.e., forwarding unit 1) to add tag (English) 100.
[vBNG-slot-1]ip unr host-route-tag 100
By setting the flag, the routing information that needs to be introduced into the first routing protocol process may be selected according to the needs of the user or the network administrator (for example, all or part of the user network side routes received on the forwarding unit 1 may be introduced, and certainly, if not set, may not be introduced), so that the routing information to be introduced is flexibly controlled according to the needs of the user or the network administrator.
Further, the first network device creates a routing policy indicating that the routing policy is satisfied if a label of a piece of routing information is a first label. And the first network equipment introduces the routing information meeting the routing strategy into the first routing protocol process for issuing.
Alternatively, creating a routing policy may be implemented on the first network device through a configuration command. For example,
a routing policy1 (english: policy1) is created under view of vBNG:
[vBNG]route-policy policy1
creating a matching identifier of the routing policy under the view of the routing policy1 as tag 100:
[vBNG-routepolicy-policy1]if-match tag 100
configured under the view of ospf process 1 of vBNG, if a piece of routing information matches tag 200, the routing information is introduced into ospf process 1:
[vBNG-ospf-1]import-route unr route-policy policy1
the routing information meeting the matching requirement is introduced into the corresponding routing protocol process by creating the routing strategy, and the routing protocol process to be introduced can be selected according to the needs of a user or a network administrator, so that the routing protocol process to be introduced is flexibly controlled according to the needs of the user or the network administrator, and the configuration management is more flexible.
The method for associating the second routing protocol process with the second forwarding unit is the same as the above-mentioned method for associating the first routing protocol process with the first forwarding unit, and for brevity, details are not described here again.
In part 203, the first network device issues routing information associated with the first routing protocol process, received from the first interface of the first forwarding unit, from the second interface of the first forwarding unit to the second network device, the routing information including IP address information of the user equipment.
As shown in fig. 1a, network device 1 issues routing information of user equipment 1 received from interface 1 of forwarding unit 1 (the routing information of user equipment 1 has been introduced into the first routing protocol process by the method of section 202) from interface 2 of forwarding unit 1 to network device 2. After receiving the routing information of the user equipment 1 from the interface 5, the network device 2 runs a third routing protocol process to generate a forwarding table entry to the user equipment 1, where the destination IP address information of the forwarding table entry is the IP address information of the user equipment 1, and the output interface is the interface 5. So that only the interface 5 is used when the network device 2 forwards data messages destined for the user device 1; then enters the forwarding unit 1 of the vBNG from the interface 2 of the vBNG through the link 1, and is forwarded out from the interface 1 of the forwarding unit 1; the data message is transmitted and received on the same forwarding unit 1, and cross-board forwarding is avoided.
By associating the first routing protocol process with the first forwarding unit, the routing received by the first forwarding unit is only issued from the interface of the first forwarding unit to the second network device on the network side, so that the second network device can only learn the routing issued from the interface of the first forwarding unit, thereby avoiding cross-board forwarding and improving the forwarding performance of vBNG.
Further, the first network device issues the routing information associated with the second routing protocol process received from the third interface of the second forwarding unit from the fourth interface of the second forwarding unit.
As shown in fig. 1a, the network device 1 issues the routing information of the user equipment 2 received from the interface 3 of the forwarding unit 2 (the routing information of the user equipment 2 has been introduced into the second routing protocol process by the method of part 202) from the interface 4 of the forwarding unit 2 to the network device 2, similarly to the above. After receiving the routing information of the user equipment 2 from the interface 6, the network equipment 2 runs the third routing protocol process (as described in the above part 201, when the network equipment 2 runs one routing protocol process) or the fourth routing protocol process (as described in the above part 201, when the network equipment 2 runs two routing protocol processes) to generate a forwarding table entry to the user equipment 2, where the destination IP address information of the forwarding table entry is the IP address information of the user equipment 2, and the output interface is the interface 6. Thus, as shown in fig. 1b, only the interface 6 is used when the network device 2 forwards the data packet destined for the user device 2; then enters the forwarding unit 2 of the vBNG from the interface 4 of the vBNG through the link 2, and is forwarded out from the interface 3 of the forwarding unit 2; the data message is transmitted and received on the same forwarding unit 2, and cross-board forwarding is avoided.
By associating each forwarding unit with each routing protocol process in a one-to-one correspondence manner, the routing received by each forwarding unit is only issued to the second network equipment on the network side from the interface of the forwarding unit, so that the second network equipment can only learn the routing issued by the interface of the forwarding unit, cross-board forwarding is avoided, and the forwarding performance of the vBNG is improved.
