摘要:
A data transmission method is provided. The method is used to transmit multiple data packets, and includes the following steps. Multiple acquired data packets are mapped to different sessions according to data header information of the data packets, in which each session corresponds to one or more data packets. A data packet is encapsulated into a session message, in which the encapsulated session message includes a session identifier of the session corresponding to the one or more data packets. Multiple session messages belonging to the same session are transmitted to a next network node through at least two tunnels in link layer.

The present disclosure discloses a method, device, and system for processing an IPv6 packet, and relates to the field of Internet technologies. According to the present disclosure, a secure access, authentication, and authorization can be ensured in an IPv6 network, and different IPv6 address prefixes are allocated to different terminals. Therefore, normal routing in the network is ensured. A method for processing an IPv6 packet provided in an embodiment of the present disclosure includes: an access node adds access line information to an IPv6 packet; and forwards the IPv6 packet that is added with the access line information to an IP edge node. The present disclosure is applicable to a scenario of processing a packet in an IPv6 network.

Embodiments of the present invention disclose a method, apparatus, and system of DAD proxy. The method includes: obtaining a DAD-NS message; comparing the obtained DAD-NS message with locally stored DAD information, and adding the DAD-NS information to the locally stored DAD information when it is determined, according to a comparison result, that the IP address to be detected is not duplicate; when it cannot be determined whether the IP address to be detected is duplicate or not, initiating, according to the address information included in the locally stored DAD information after comparison, an unreachability detection to the IP address to be detected to determine whether the IP address to be detected is duplicate. The apparatus includes: an obtaining module, a storing module, and a processing module. The system includes: an apparatus of DAD proxy and an access device.

A method and a system for forwarding data in layer-2 network are disclosed. The method includes: configuring a virtual MAC address and a virtual MAC forwarding table for each node in a management domain in a layer-2 network; encapsulating a data packet with a source virtual MAC address and a destination virtual MAC address; and forwarding the data packet by each node on the data forwarding path according to the virtual MAC forwarding table configured for each node. A node and a system for forwarding data in layer-2 network are disclosed as well. The present disclosure frees the number of ESPs reaching a destination device from being limited by the number of designated PBT VIDs. Therefore the number of ESPs arriving at the destination device is expanded actually to 260 tag possibilities in limited network space; furthermore, P2MP and MP2MP connections is achieved, multicast and broadcast connections are supported.

In the field of communications, a method and a system for packet transmission in an optical communication system, and an Optical Line Terminal (OLT) are provided. The method includes: receiving, from a port, a first uplink packet from an Optical Network Unit (ONU), where the first uplink packet includes a Logical Link Identifier (ID); determining a first ID corresponding to the first uplink packet, where the first ID includes an ONU ID or a Port ID; acquiring a Multiprotocol Label Switching (MPLS) tunnel label according to the Logical Link ID and the first ID; and transmitting a second uplink packet on an MPLS tunnel corresponding to the MPLS tunnel label, where the second uplink packet includes data in the first uplink packet and the MPLS tunnel label. The system includes an ONU and an OLT. By establishing a corresponding relation of a logical link, created between the OLT and the ONU, and the MPLS tunnel, mapping between the logical link and the MPLS tunnel is realized, so that the service configuration has an unlimited capacity and becomes more flexible.

A binding/unbinding processing method, system and apparatus are disclosed. The binding processing system includes: an Internet Protocol (IP) edge node and an Access Node (AN). The IP edge node is configured to: monitor received Dynamic Host Configuration Protocol (DHCP) messages, after monitoring a specific DHCP message, forward the specific DHCP message to all ANs corresponding to bound links, where the specific DHCP message is a DHCP ACK or DHCP REPLY message. The AN is configured to: receive the specific DHCP message sent by the IP edge node, parse and obtain an IP or Media Access Control (MAC) address carried in the specific DHCP message, and bind a port of the AN to the IP or MAC address according to the obtained IP address or MAC address. The present disclosure implements the binding/unbinding of an AN port to/from an IP or MAC address in inter-AN binding scenarios.

Embodiments of the present disclosure provide a method for transmitting an Internet Protocol version 6 (IPv6) message in a Passive Optical Network (PON). The method includes: receiving a Router Advertisement (RA) message comprising Optical Line Terminal (OLT) port information, Optical Network Unit (ONU) port information, and an IPv6 address prefix; binding the IPv6 address prefix with an OLT port indicated by the OLT port information; and sending the RA message to an ONU through the OLT port, so that the ONU binds the IPv6 address prefix with an ONU port indicated by the ONU port information and provides the RA message for a user terminal through the ONU port. Embodiments of the present disclosure further disclose a PON system and an apparatus for transmitting an IPv6 message in a PON.
