Description

Weight-based private line gateway method and device

Technical Field

The invention relates to the field of computers, in particular to a weight-based private line gateway method and device.

Background

In the prior art, a IDC (Internet Data Center) internet data center is connected to two pop-point-of-presence private line access points through a private line. Each pop private line access point is connected with two 10G private lines. IDC issues the route of network segment 10.10.0.0/16 to the outside, after the switch DP-SW1/DP-SW2 of the pop private line access point learns the IDC network segment, it generates the ECMP (Equal Cost Multi-path) equivalent route of two next hops, the next hops are two private line channels 1,2 or 3,4 respectively. The switch would issue traffic equalization from both 10G ports to the IDC side according to the set equivalent routing hashing algorithm. The switches DP-SW1/DP-SW2 will also post learned routes to the CORE switch CORE. When the switch DP-SW1/DP-SW2 issues a route, the next hop is modified to the IP of the switch DP-SW1/DP-SW 2. The CORE switch CORE learns the ECMP equivalent route for the two next hops. The next hops are DP-SW1, DP-SW2, respectively. The CORE switch CORE is only aware of DP-SW1, DP-SW2. The dedicated channels 1,2,3,4 are not perceived. If the dedicated line channel 1 is disconnected at this time. The bandwidth equivalent to DP-SW1 becomes 10G, while the bandwidth of DP-SW2 is 20G. And CORE cannot perceive this change. For CORE, there is still an ECMP equivalent route for the two next hops DP-SW1, DP-SW2. Traffic sent to DP-SW1, DP-SW2 is equal, and may exceed the maximum bandwidth of 1 10G dedicated line for DP-SW 1. It is not possible to achieve the following 1: weighting of 2, traffic sent to IDC is carried out.

1. and adding weight attribute for the route when the route of the switch issues the flow.

Weight attribute: is the sum of all the route next hop network interface rates, in Mbyte.

For example, in the example where the first switch initially publishes the routing information, the added weight attribute is 10g+10g=20480 mbytes.

When the first dedicated channel of the first switch is abnormal, the first switch reissues the route, and the weight attribute is 10g=10240 Mbyte.

10.10.0.0/16 next hop first switch (1)

Second exchanger (2)

3. After the CORE exchanger hits the weight routing table, the flow distribution is carried out according to the weight proportion.
