Abstract: Disclosed are a service disaster recovery backup method, a service disaster recovery backup system and a traffic offload (TOF) node. The service disaster recovery backup method includes: after joining a cluster of TOF nodes, querying each TOF node in the cluster for a service data abstract, a keyword in the service data abstract is an identifier of the first TOF node; when the service data abstract is not queried, undertaking, as an activation node, a local breakout service of service data of the first TOF node, selecting a second TOF node as a backup node in the cluster, and publishing the service data abstract with the identifier of the first TOF node as the keyword in the cluster.

Abstract: At least some embodiments of invention provide a method, device and system for link management in a Virtual Machine (VM) environment. The method includes: a heartbeat handshake link is established with a VM. After the heartbeat handshake link is successfully established, Link Aggregation Control Protocol (LACP) state information of a Physical Function (PF) of a plurality of a Network Interface Cards (NICs) is acquired. The LACP state information is sent to the VM through the heartbeat handshake link.
