Embodiments of the present disclosure provide a hot standby method, apparatus, and system. The method includes: saving, by an active device, first user information of the active device into a local cache module of the active device and sending, by the active device, the first user information to a remote cache module of a first standby device based on preset correlation information. In response to detecting that the active device becomes faulty, the first standby device obtains the first user information from the remote cache module of the first standby device and restores the first user information.

The present disclosure discloses a method, an apparatus and a system for determining a service transmission path. The method includes: receiving a service chaining object sent by a client device based on an expanded path computation element communication protocol (PCEP), wherein the service chaining object includes service processing capacities that service nodes need to provide when transmitting a service in a network; determining at least one service node matched with the service chaining object in the network according to service processing capacities that service nodes in pre-stored service node attribute information are capable of providing; and generating a service transmission path based on the determined service nodes, for transmitting the service initiated by the client device. The problems of large flow pressure and low utilization rate of the service nodes deployed in the network may be well solved.

Method, apparatus and system for determining service transmission path

Embodiments of the present invention provide a cluster that includes a first node and a second node, and the first node and the second node are configured to cooperatively perform a forwarding service on a first packet, where the first node is configured to receive the first packet by using an inbound interface and determine the inbound interface; and the second node is configured to determine an outbound interface according to a forwarding table corresponding to the forwarding service and forward the first packet by using the outbound interface of the second node. In addition, the embodiments of the present invention further provide other clusters and forwarding methods. The foregoing technical solutions help to reduce software and hardware resources occupied by a cluster.

Cluster and forwarding method

The embodiments of the present invention disclose a method, an apparatus, and a system for controlling network traffic switching. The method for controlling network traffic switching includes: establishing a direct link interface, where the direct link interface has an address attribute of a peer node, and a value of the attribute is a peer node address of the direct link; and comparing a border gateway protocol (BGP) next-hop address of each route in a routing table with the peer node address of the direct link, and switching traffic on a route that matches a comparison result to the direct link. By using the preceding technical solution, after a direct link is established between nodes, a relevant node establishes a new type of interface for the direct link.

Method, apparatus, and system for controlling network traffic switching

The present invention discloses a method for obtaining IPv6 configuration information in an IPv6 transition network. The network includes an IPv4 network and an IPv6 network. An apparatus for providing IPv6 configuration information in the IPv4 network receives an IPv6 configuration information obtaining request packet sent by a user side device. In response, the apparatus sends a response packet to the user side device, where the response packet is a DHCPv4 packet, and carries the requested IPv6 configuration information. Some of the advantages of the present invention are that automatic configuration for a user side device which needs to traverse the IPv4 network to access the IPv6 network is implemented, and efficiency is greatly improved compared with a manual configuration method in the prior art.
