Provided are a service function chain detection path method and device. The method comprises: sealing a sending service function chain path identifier and a returning service function chain path identifier in a message header, and obtaining a service function chain detection message, the sending service function chain path identifier being used for indicating a path of the service function chain detection message, the returning service function chain path identifier being used for indicating a path of a service function chain detection reply message corresponding to the service function chain detection message; sending the service function chain detection message; receiving the service function chain detection reply message, the service function chain detection reply message comprising returning path information, the returning path information being used for indicating a service function chain path of the service function chain detection message during sending.

Service function chain detection path method and device

An information transmission method and device, comprising: when being connected to a virtual network, a network edge node encapsulates the virtual network identifier of the connected virtual network in a multicast protocol packet; the network edge node sends the multicast protocol packet to network edge nodes other than itself. The information transmission method can implement delivery of a virtual network identifier, thereby implementing highly efficient transmission of virtual network data.

Information transmission method and device

The present disclosure relates to an information processing method, comprising: encapsulating, in a link layer discovery protocol data unit (LLDPDU), bit indexed explicit replication (BIER) bit string length information of a first node; and sending to a second node the LLDPDU, wherein the second node is an adjacent node of the first node, and the BIER bit string length information of the first node is used to forward BIER traffic. The present disclosure also relates to an information processing device.

Information processing method and device, and computer storage medium

An information transmission method, comprising: a control platform generating forwarding information of a bit indexed explicit replication (BIER) network; and the control platform sending, according to the forwarding information of the BIER network, a BIER flow table to a forwarding device through an OpenFlow protocol. The solution solves the problems that, in a forwarding mode for a multicast message in the relevant OpenFlow technology, a space occupied by an entry is larger and the forwarding efficiency is lower because it is necessary to establish a corresponding flow table and group table on each forwarding device for each flow.

Information transmission method, apparatus and system

The present disclosure provides a packet transmission method and apparatus. The method includes: a classifier receiving a first packet; the classifier determining a first service function (SF) to which the first packet is to be transmitted; the classifier adding an address of the first SF to the first packet, obtaining a second packet; and the classifier transmitting the second packet to a network virtualization edge (NVE) node.

Packet transmission method and apparatus

Provided are a method and device for processing a data message. The method may include that: an Internet Protocol version 6 (IPv6) transition strategy used for executing an IPv6 transition technology is received from a Service function chain (SFC) controller; and a received data message is processed according to the received IPv6 transition strategy. By the technical solution, the problems of incapability of a network system in effective running during fusion with an IPv6 transition technology and incapability in effective implementation of unified deployment of the IPv6 transition technology in the related technology are solved, and the effects of effectively reducing performance pressure on an existing network and greatly alleviating channel congestion between equipment and equipment are further achieved.

Method and device for processing data message

Provided are a method, device and system for implementing address sharing. An address pool configured for unified management over IP addresses is configured on an AAA server; and the AAA server may allocate an IP address to a CGN device according to the configured address pool. By such a technology for implementing address sharing in the present disclosure, IP address resource sharing among CGN devices is implemented, so that problems about resource load sharing among the CGN devices may be solved, a sharing rate of IP address resources is increased, and resource optimization may be implemented; and moreover, in terms of IP address management, a more available platform is provided for an operating company. In addition, the IP addresses are managed by the AAA server in a unified manner, and then the address pool is not required to be configured on the CGN device, so that the CGN device may be started without any address pool.

Method, device and system for implementing address sharing

A service node capability processing method and apparatus, a service classifier and service controller are described. The method includes: determining an exchange information set of service nodes on a service function chaining for processing a data packet, wherein the exchange information set includes an intersection of capabilities of the service nodes on the service function chaining; and encapsulating the exchange information set in the data packet, wherein the exchange information set is used for the service nodes to read a processing result which is obtained by processing capability corresponding to the intersection of the capabilities of the service nodes and which is encapsulated in the data packet. In such a fashion, the problem in the related technology is addressed that the blind information exchange causes the waste of resources since the information exchange between nodes is untargeted, and consequentially effectively avoids the waste of field resources by invalid information exchange.

Method and apparatus for processing service node ability, service classifier and service controller

The disclosure discloses a method and device for processing a Service Function Chaining (SFC). The method includes that: the SFC receives a message sent from forwarding equipment; the SFC generates a forwarding table corresponding to the message; and under a condition that a preset state of a forwarding table sending switch is on, the SFC sends the forwarding table to the forwarding equipment to make the forwarding equipment forward the message according to the forwarding table when receiving the message, wherein the forwarding table sending switch is used for indicating the SFC whether to send the forwarding table to the forwarding equipment or not. By the disclosure, an effect of increasing a success rate of data forwarding of the SFC is achieved.
