Abstract:
The present invention provides a method for a virtual private cloud to access a network, a network side device and a data center device. When receiving a VPC configuration resource provided by a user, the network side device and the data center device exchange information, create a VPC, determine a PE interface address, a VCE uplink port address, an access tunnel and a VCE downlink port address for the VPC, and perform a corresponding configuration operation, thereby enabling the VPC to access a VPN in a basic bearer network without the need of uniform management of a control system, so as to solve a problem that the VPC cannot access the network when the basic bearer network and a data center belong to different operators, and meanwhile, save a device resource.
Abstract:
A method can be used for authenticating access of a virtual private cloud, which are used for performing VPC access authentication between networks that communicate with each other using an IP routing protocol. A VPN routing device receives a request for accessing a virtual private network VPN by a virtual private cloud VPC. The request is sent by a cloud manager. The request for accessing a VPN by a VPC carries an identifier of a bearer network of a target VPN and a VPN identifier. The VPN routing device sends the VPC access request to a network edge device corresponding to the identifier of the bearer network. The VPC access request carries the VPN identifier.
Abstract:
A packet transmission method and apparatus, and a system. The method includes: after receiving a first packet, a first device determines, based on a condition met by a first number carried in the first packet, a manner of sending the first packet. When the first number of the first packet meets a first condition, a second device determines a second cycle label corresponding to a first cycle label and sends the first packet to a third device in a cycle corresponding to the second cycle label. When the first number of the first packet meets a second condition, the second device determines a third cycle label corresponding to the first cycle label and sends the first packet to the third device in a cycle corresponding to the third cycle label.
Abstract:
This application provides a route information processing method, a communication apparatus, and a communication network, applied to the communication technology field. The route information processing method is used on a target node in a first network. The first network is addressed based on a tree first topology structure, and an address of a child node in the first topology structure includes an address of a parent node. Therefore, a node in the first network may calculate a route based on a destination address. When a topology structure of the first network is updated from the first topology structure to a second topology structure, and a connection relationship of a first node changes, the target node in the first network may add route information destined for the first node, so that the target node can still correctly address the first node and a descendant node of the first node.
Abstract:
Embodiments of this application provide network traffic marking and measurement methods and a node, and relate to the field of communications technologies, and specifically, to network traffic measurement and network traffic distribution. The network traffic measurement method includes: receiving, by a second node, a data packet sent by another node in a network, where the data packet is periodically marked by the another node, and each node has a different period of marking a data packet. According to the application, the second node may distinguish, based on the period of marking the data packet, traffic sent by the another node in the network, to obtain network traffic sent by the another node in the network to the second node. Upon implementing the traffic measurement method, data plane overheads can be reduced, and a hardware implementation process is simplified.

Abstract:
The application provide a packet sending method, a router, and a service switching entity. According to the application, a router determines a flow group identifier of a service packet and information about a next-hop service switching entity according to a user identifier and IP 5-tuple information; and forwards the packet to the next-hop service switching entity according to the information about the next-hop service switching entity, so that the next-hop service switching entity determines a corresponding destination service instance according to the user identifier, the flow group identifier, a router identifier, and a processing result, and forwards the packet to the destination service instance, to perform corresponding service processing, thereby implementing service packet forwarding among service instances. The router in the method provided in the embodiments has a flow steering function, and steers a flow to a specified path to perform node-by-node processing.
Abstract:
Embodiments disclose a packet forwarding method and device. The method includes: obtaining, by a packet forwarding device, a feature character included in a packet to be forwarded. The feature character is obtained by parsing, according to a preset packet content parsing policy, other content included in the packet to be forwarded except a 5-tuple. The method includes determining, according to a correspondence between different feature characters and corresponding routing information, routing information corresponding to the obtained feature character, and sending, according to the determined routing information, the packet to be forwarded
