Problems solved by technology

[0003] In EVPN, in order to improve reliability, a multi-homing access network is adopted, that is, a CE (Customer Edge, user network edge) device is connected to multiple PE (Provider Edge, service provider edge) devices, and these PE devices are connected to multiple In the active redundancy backup mode, the equal-cost load sharing method is used to forward data packets, which will waste resources due to the inconsistency of the link bandwidth between each PE device and CE device.

Abstract

The invention discloses a load sharing method, the method is applied to a first PE equipment in a multi-homing network, the multi-homing network further comprises a second PE equipment and a CE equipment, the CE equipment accesses the first PE equipment in a multi-homing manner, the first PE equipment and the second PE equipment belong to different homing systems, and the method comprises the following steps: obtaining bandwidth information between the first PE equipment and the CE equipment; and sending a routing announcement containing bandwidth information to the second PE equipment, so that the second PE equipment forwards the traffic to be sent to the CE equipment to the CE equipment in a non-equivalent load sharing mode according to the bandwidth information, thereby optimizing the problem of resource waste caused by inconsistent link bandwidths between the PE equipment and the CE equipment.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a load sharing method, device, equipment, and machine-readable storage medium. Background technique [0002] EVPN (Ethernet Virtual Private Network, Ethernet Virtual Private Network) is a Layer 2 VPN (Virtual Private Network, Virtual Private Network) technology, and the control plane adopts MP-BGP (MultiProtocol-Border Gateway Protocol, Multi-Protocol-Border Gateway Protocol) notification For routing information, the data plane uses MPLS (Multi-Protocol Label Switching, Multi-Protocol Label Switching) encapsulation to forward data packets. [0003] In EVPN, in order to improve reliability, a multi-homing access network is adopted, that is, a CE (Customer Edge, user network edge) device is connected to multiple PE (Provider Edge, service provider edge) devices, and these PE devices are connected to multiple In the active redundancy backup mode, the equal-co...
