Problems solved by technology

[0005] However, in related technologies, the implementation of two-dimensional routing is limited to intra-domain networks, and there is no inter-domain routing protocol that supports inter-domain two-dimensional routing. In addition, the deployment of two-dimensional routing networks in related technologies is mostly static configuration. Heavy workload

Embodiment 1

[0106] as attached Image 6 As shown, the border devices R1 and R2 of the AS1 domain support two-dimensional routing and forwarding. R1 has obtained the trusted source 192:168:1::0 / 64 for accessing the SERVER, and R2 has obtained the trusted source 192 for accessing the SERVER: 168:2::0 / 64, share flows from different sources through R1 and R2. If it is desired to achieve traffic load sharing in the AS2 domain, the border devices R3, R4, and R5 of the AS2 domain can be upgraded to support two-dimensional route forwarding, and the BGP protocol can be upgraded according to the present invention to support dynamic learning of two-dimensional routes.

[0107] Between R1 and R3, an EBGP (External Border Gateway Protocol, external border gateway protocol) neighbor is established, and the receiving and advertising capabilities of two-dimensional routes are both enabled.

[0108] Between R2 and R4, EBGP neighbors are established, and the receiving and sending capabilities of tw...

Embodiment 2

[0116] as attached Figure 7 As shown, the border device R1 of the AS1 domain supports two-dimensional routing and forwarding, and has obtained the trusted source address 192:168:1::0 / 64 for accessing the server, and the attack traffic can be filtered on the R1 device. If you want to filter attack traffic in the AS2 domain, you can upgrade the border devices R2 and R3 in the AS2 domain to support two-dimensional route forwarding, and upgrade the BGP protocol to support dynamic learning of two-dimensional routes.

[0117] Between R1 and R2, EBGP neighbors are established, and the receiving and sending capabilities of two-dimensional routes are enabled.

[0118] Between R2 and R3, establish an IBGP neighbor relationship, and enable the receiving and sending capabilities of two-dimensional routes.

[0119] R1 configures network 10:1:1::0 / 64 192:168:1::0 / 64 to route two-dimensionally (10:1:1::0 / 64,192:168:1::0 / 64) Import BGP and send the two-dimensional route to R2.

Embodiment 3

[0123] as attached Figure 8 As shown, the border device R1 of the AS1 domain supports two-dimensional routing and forwarding, and has obtained the trusted source address 192:168:1::0 / 64 for accessing the server, and the attack traffic can be filtered on the R1 device. If it is desired to filter attack traffic in the AS2 domain, but the AS2 device cannot perform two-dimensional routing upgrades on all border devices, there will be a mixed network of one-dimensional routing and two-dimensional routing. For example, in AS2, R2 can be upgraded, but R3 cannot be upgraded. Finally, attack traffic can be filtered on R2.

[0124] Between R1 and R2, EBGP neighbors are established, and the receiving and sending capabilities of two-dimensional routes are enabled.

[0125] Between R2 and R3, an IBGP neighbor is established, and neither the ability to receive two-dimensional routes nor the ability to send two-dimensional routes is enabled.

[0126] R1 configures network 10:1:1:...

Abstract

The invention discloses a method for realizing two-dimensional routing of a border gateway protocol. The method comprises the following steps: negotiating sending and / or receiving ability of two-dimensional routing of the border gateway protocol BGP by an opposite end routing device; in the case that the opposite end routing device successfully negotiates the sending ability of the two-dimensional routing of the BGP, sending the two-dimensional routing of the BGP by the opposite end routing device; and in the case that the opposite end routing device successfully negotiates the receiving ability of the two-dimensional routing of the BGP, receiving the two-dimensional routing of the BGP sent by the opposite end routing device. By adoption of the method, inter-domain two-dimensional routing can be realized to quickly deploy a two-dimensional routing network, thereby facilitating the network management and optimizing the network performance.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and a device for realizing two-dimensional routing of the Border Gateway Protocol. Background technique [0002] Traditional routing protocols based on destination addresses (called one-dimensional routing protocols here) can no longer meet the needs of users. For example, they cannot solve the problem of multi-homing in the network. Traditional routing protocols only look at destination addresses and treat all sources equally. But in reality, different sources may require different services. [0003] Devices that support two-dimensional routing protocols can distinguish traffic from different sources during routing by introducing source addresses when making routing decisions, and achieve other purposes such as traffic balancing and routing security. [0004] For example, in figure 1 , the AS2 domain is connected to two upstream ISPs (Internet Service Providers,...
