Example Embodiment

[0024] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0025] See figure 1 As shown, the embodiment of the present invention provides a system for backup between link aggregation groups in a packet switching network, which includes a first device and a second device, and the internal configuration of the first device and the second device are the same.

[0026] The embodiment of the present invention also provides a method for backup between link aggregation groups in a packet switching network based on the above system, which includes the following steps:

[0027] S1. The system configures the first link aggregation group Trunk1 on the first device, and configures the first link aggregation group Trunk1 of the same mode on the second device to ensure normal operation; then configure the second link on the first device Link aggregation group Trunk2 corresponds to the second link aggregation group Trunk2 of t...

Abstract

The invention discloses a system and method for backup between link aggregation groups in a packet switched network, and relates to the field of packet switched networks. The method includes the following steps that a Trunk 1 is configured on a first device, a Trunk 1 is configured on a second device, and normal work is guaranteed, wherein the Trunk 1 on the first device and the Trunk 1 on the second device are in the same mode; a Trunk 2 is configured on the first device, a Trunk 2 is configured on the second device, and normal work is guaranteed, wherein the Trunk 2 on the first device and the Trunk 2 on the second device are in the same mode; the system randomly assigns one aggregation group in the Trunks 1 and the Trunks 2 to work in a priority mode, and the other aggregation group is automatically in a backup state; when faults occur in a link of an active link aggregation group between the first device and the second device, the system assigns an inactive link aggregation group to be in a working state, and services of the fault link are switched into a link of the inactive link aggregation group for transmission, wherein the Trunks 1 and the Trunks 2 are in the same mode or in different modes. Service flow of the fault link aggregation group is switched into the other standby aggregation group, and therefore the services are protected.

Description

technical field [0001] The invention relates to the field of packet switching networks, in particular to a system and method for backup between link aggregation groups in the packet switching network. Background technique [0002] With the development of society, the growth of data traffic and the high requirements of service quality, in the packet switching network, MPLS (Multi-Protocol Label Switching, multi-protocol label switching), MPLS_TP (MPLS-Transport Profile, transport-oriented Multi-protocol label switching), VLAN (Virtual Local Area Network, virtual local area network) switching and other technologies to achieve traffic engineering. Before user data transmission, formulate service level agreements according to user requirements, pre-allocate data forwarding paths and bandwidth resources through control protocols, form service flows with guaranteed quality of service such as bandwidth, and further adjust services when the status of network resources changes The f...
