Abstract: This application provides a service flow configuration method. In the method, a control device receives a first DHCP packet sent by a DHCP server, where the first DHCP packet includes an IP address of a server configured to provide a configuration file, an identifier of the configuration file, and an IP address of a user-side terminal. The control device replaces, with an IP address of the control device, the IP address being in the first DHCP packet and being of the server configured to provide the configuration file, and sends the IP address of the control device to the terminal by using a second DHCP packet. The control device receives a first request packet including the identifier of the configuration file. The control device obtains, based on the identifier of the configuration file from the server configured to provide the configuration file, a configuration file corresponding to the terminal.

Abstract: This application provides a packet processing method, which helps resolve a problem that a network node between a user terminal and a DHCP server is relatively complex. In the method, a network node of an access network receives a first packet sent by a user terminal, where the first packet is used to request an Internet Protocol IP address from a Dynamic Host Configuration Protocol DHCP server and the network node obtains a second packet, where the second packet includes the first packet, information about a port, and a Media Access Control MAC address of the user terminal, the port is a port through which the network node receives the first packet, and the second packet is a packet except a DHCP packet. Additionally the network node sends the second packet to a controller.

Abstract: This application provides a method for processing a packet in an access network. The method includes: receiving, by an access device, a layer 2 protocol packet sent by a central device, where a destination address of the layer 2 protocol packet is a MAC address of the access device; obtaining, flow table information according to the layer 2 protocol packet, and generating a flow table entry, where the flow table entry includes a match field and an instruction; receiving a service packet; and determining a matching flow table entry according to the service packet, and when the matching flow table entry is the generated flow table entry, processing the service packet according to the instruction in the generated flow table entry. According to the technical solution, the access device can obtain the flow table information from the central device without the need of configuring a public IP address.

Abstract: Embodiments of the present invention relate to the field of communications technologies and provide a service processing method, device, and system, where service expansion can be performed without changing an original device of an operator. A service processing method includes acquiring business service information corresponding to a to-be-processed service flow, where the business service information includes a service flow identifier of the to-be-processed service flow and a service label corresponding to the service flow identifier. The method includes sending the business service information corresponding to the to-be-processed service flow to a service router, so that the service router processes, according to the business service information, the to-be-processed service flow.

Abstract: A method, an apparatus, and an edge node controller for selecting an edge node. The edge node controller receives a service request message including a subscriber identifier; obtains the subscriber identifier in the service request message; queries a first mapping relationship between the subscriber identifier and an edge node address according to the subscriber identifier to obtain an edge node address corresponding to the subscriber identifier; and returns a service response message including the edge node address. A subscriber identifier carried in a service request message is used to query a first mapping relationship to obtain an edge node address, and a service response message carrying an address of an edge node selected for a subscriber is delivered, thereby reducing a processing process of identifying different edge nodes by an external server, improving the processing efficiency, and reducing the implementation complexity.

Abstract: The present invention discloses a method for advertising routing information, and embodiments of the present invention further provide a virtual private network server device, an IP edge node device, and a client-based virtual private network system. In the technical solutions of the present invention, a virtual private network server first collects MAC address routing information of each site on a local virtual private network and then sends MAC address routing information of each site except a destination site in a unicast manner to a customer edge node that corresponds to each site on the virtual private network. This solves the problem that CE nodes in sites on the virtual private network cannot exchange routing information with each other by using a routing protocol because multicast packets are filtered by an access node of the data center network.

Abstract: Embodiments of the present invention provide an access system and a communication method for an optical fiber network. A virtual ONU located on a user side is established, and an ONU control plane function, a PON MAC function, and a QoS function on an existing ONU is moved downwards to a virtual ONU. After the forgoing function modules are removed from the existing ONU, the existing ONU becomes an ONU physical converter and only has a function of converting the PON physical layer frame and the first user side physical layer frame.
