Problems solved by technology

If there is a disconnection between CE and PE, the data packets sent by the client will be discarded
At the same time, when the traffic forwarded by the client exceeds the tunnel bandwidth, it will cause tunnel congestion, resulting in some data packets being discarded
Therefore, the security between CEs on both sides of the operator's network is greatly reduced

specific Embodiment

[0064] Specific embodiments: when the carrier network is a T-MPLS network, realize the link aggregation control method that traverses the carrier network, as shown in Figures 3 and 4, the link from CE1 to CE2 is bidirectional, including the following steps:

[0065] Step 301: aggregate the links M and N between CE1 and CE2 to form an aggregation group;

[0066] Specifically, create link aggregation groups on CE1 and CE2 respectively, add the ports of CE1 and CE2 used by link M and link N between CE1 and CE2 to the corresponding aggregation groups, and set Determined routing rules.

[0067] Step 302: On the links M and N, the detection is performed after the configuration between CE1 and PE1 according to the CFM protocol, and the detection is performed after the T-MPLS tunnel between PE1 and PE2 is configured according to the T-MPLS OAM protocol;

[0068] Step 303: PE1 and PE2 synchronize the link status information of links M and N obtained by CE1 and CE2 according to the lin...

Abstract

The invention discloses an aggregation control method of links passing through a provider network, which aggregates a plurality of links between client equipments (CE) at both sides into an aggregated group; on each link, the CEs and provider equipments (PE) directly connected with the provider network are configured according to a connection fault management (CFM) protocol and then carry out detection, and the PEs at both sides are configured according to a corresponding provider network operation, management, maintenance (provider network OAM) and protocol configuration, and then carry out detection; according to the detected link state, the PEs synchronize link state information obtained by the CEs at both sides; when the CEs know that the state of a link is disconnection, the link is removed from the aggregated group; and when the CEs know that the state of the link is connection, the link is added into the aggregated group. Meanwhile, the invention also discloses a link aggregation control system passing through the provider network. The scheme can enhance the safety of the CEs at both sides of the provider network and realize the sharing of load between the CEs.

Description

technical field [0001] The invention relates to the link aggregation control technology of the transmission layer, in particular to a link aggregation control method and system for traversing operator networks. Background technique [0002] As far as the existing Transport Multiprotocol Label Switching (T-MPLS) link is concerned, it includes: the customer end equipment (CE, Custom Edge) directly connected to the operator's network; the edge equipment of the operator's network, that is, the tunnel edge node (PE , Provider Edge); the operator network intermediate device, that is, the tunnel intermediate node (P, Procider). [0003] Operation, Administration, and Maintenance of the T-MPLS tunnel between PEs on both sides are referred to as T-MPLS OAM, and Operation, Administration, and Maintenance are abbreviated as OAM. Among them, the operation mainly completes the analysis, forecast, planning and configuration of the daily network and services; the maintenance mainly refers...
