The present disclosure discloses a flow specification (FlowSpec) message processing method. In the method, a controller forwards device interface information reported by the forwarding device; selects at least one forwarding device interface to which a FlowSpec rule needs to be applied from the received forwarding device interface information; generates an application interface rule based on the at least one forwarding device interface to which the FlowSpec rule needs to be applied; and sends a FlowSpec message to the forwarding device.

FlowSpec message processing method and system, and apparatus

A route processing method includes obtaining, by a first network device, a flow effective time parameter and a route related to the flow effective time parameter, processing, by the first network device in the specified time interval, service traffic corresponding to the route related to the flow effective time parameter, generating a route control message, where the route control message carries the flow effective time parameter and the route, and sending, by the first network device, the route control message to a second network device.

The present invention discloses a service processing method and apparatus, and relates to the communications field. The method includes: receiving trigger information sent by an intermediary device; and assisting, based on the trigger information, the intermediary device in negotiating with UE and a network server, to enable the intermediary device to obtain a first key, where the first key is used by the intermediary device to decrypt ciphertexts sent by the UE and the network server, the ciphertext is obtained after the UE or the network server encrypts service information by using a second key, and the first key is corresponding to the second key. The present invention resolves a problem that an intermediary device cannot provide service optimization for user equipment and a network server because the intermediary device cannot decrypt ciphertext, and achieves an effect of expanding a usage scope of service optimization.

Service processing method and apparatus

A packet processing method and an apparatus are provided. A first SFC proxy of a first SF entity splits a first packet to obtain a first original packet and a first SFC header, and the first SFC proxy sends the first SFC header to a second SFF. The first SF entity processes the first original packet to obtain a second original packet, and sends the second original packet to a service classifier. The service classifier sends, to the second SFF, a second packet that is obtained after the service classifier adds a second SFC header to the second original packet. The second SFF changes the second SFC header in the second packet into the first SFC header. In this way, a first packet carrying a first SFC header can be transmitted in a network architecture in which a legacy SF exists, so that the legacy SF becomes compatible.

A route processing method, a device, and a system, where the method includes obtaining, by a first network device, a flow effective time parameter and a route related to the flow effective time parameter, processing, by the first network device in the specified time interval, service traffic corresponding to the route related to the flow effective time parameter, generating a route control message, where the route control message carries the flow effective time parameter and the route, and sending, by the first network device, the route control message to a second network device. Therefore, limited-time effective information is automatically disseminated, a limited-time effective requirement for a traffic control policy is met, configuration workload is reduced, and maintenance difficulty is lowered.

A method and device for informing user address are disclosed. The method comprises: a defined network allocating, according to a user address prefix provided by a mobile network, a user address to a mobile network user accessing the mobile network from the defined network; and the defined network informing the mobile network of the allocated user address. The disclosure address the problems of complex flow for allocating user address and low allocation efficiency, and how to inform a mobile network of an allocated user address existing in the related art, thus achieving the allocation of an user address and improving informing efficiency.
