A packet processing method includes receiving, by a forwarding plane device, a first packet transmitted by a user, where an identity of the user is comprised in the first packet, and a forwarding table is comprised in the forwarding plane device, determining, by the forwarding plane device, an identity of a service according to a corresponding relationship between the identity of the user and the identity of the service as well as the identity of the user in the first packet, generating, by the forwarding plane device, a second packet by encapsulating the first packet with the identity of the service, and transmitting the second packet to a network device to enable the network device to manage the service according to the identity of the service in the second packet.

Packet processing method, forwarding plane device and network device

Embodiments of the present invention provide a packet processing method, a forwarding plane device and a network device, the method includes: receiving, by a forwarding plane device, a first packet transmitted by a user, where an identity of the user is comprised in the first packet, and a forwarding table is comprised in the forwarding plane device; determining, by the forwarding plane device, an identity of a service according to a corresponding relationship between the identity of the user and the identity of the service as well as the identity of the user in the first packet; generating, by the forwarding plane device, a second packet by encapsulating the first packet with the identity of the service; and transmitting the second packet to a network device, to enable the network device to manage the service according to the identity of the service in the second packet.

A packet forwarding method and apparatus pertaining to the field of communications technologies are disclosed. The method includes: determining whether a current to-be-sent target packet is a header packet or a following packet in a burst sequence; when the target packet is the following packet in the burst sequence, obtaining port information of an egress port used to send the burst sequence, where the port information of the egress port is determined and stored when the header packet in the burst sequence is sent, and the burst sequence is a sequence including a plurality of packets that belong to a same service flow; and sending the target packet through the obtained egress port.

Packet forwarding method and apparatus

This application discloses an optical backplane system, which includes a first upper-level optical interconnection module, a first lower-level optical interconnection module, and a second lower-level optical interconnection module. The first upper-level optical interconnection module includes M1 first interfaces and N1 second interfaces in connection relationships. The first lower-level optical interconnection module includes L1 third interfaces and K1 fourth interfaces in connection relationships. The second lower-level optical interconnection module includes L2 third interfaces and K2 fourth interfaces in connection relationships. The first upper-level optical interconnection module is connected to one of the L1 third interfaces of the first lower-level optical interconnection module by using one of the N1 second interfaces. The first upper-level optical interconnection module is connected to one of the L2 third interfaces of the second lower-level optical interconnection module by using another one of the N1 second interfaces.

A packet processing method, a forwarding plane device and a network device, where the method includes receiving, by a forwarding plane device, a first packet transmitted by a user, where an identity of the user is comprised in the first packet, and a forwarding table is comprised in the forwarding plane device, determining, by the forwarding plane device, an identity of a service according to a corresponding relationship between the identity of the user and the identity of the service as well as the identity of the user in the first packet, generating, by the forwarding plane device, a second packet by encapsulating the first packet with the identity of the service, and transmitting the second packet to a network device to enable the network device to manage the service according to the identity of the service in the second packet.

Embodiments provide a method, including: receiving, by a forwarding element, a packet through an inbound port; searching for, by the forwarding element, a port table according to the inbound port and determining a first offset, a first length, and an identifier of a first table; determining, by the forwarding element, a first key according to the first offset and the first length, searching for the first table according to the first key, and determining a first instruction; and processing, by the forwarding element, the packet according to the first instruction. In addition, a forwarding element is provided. In the foregoing technical solutions, before processing a packet, the forwarding element does not need to interpret a data format of the packet, so that the forwarding element can flexibly support packets in different data formats.

The embodiments of the present invention provide a method and a system for implementing protection switching in Multi-protocol Label Switching (MPLS) network, the method includes: transmitting by a first Egress Label Switched Router (LSR) first probe packets to an Ingress LSR via a first Label Switching Path (LSP); switching by the Ingress LSR working traffic to a third LSP terminated at a second Egress LSR when the Ingress LSR does not receive the first probe packets. According to the embodiments of the present invention, the Ingress LSR may learn the failure of the Egress LSR according to the result of receiving the probe packets when a failure of the Egress LSR occurs, and switches the working traffic correspondingly. Moreover, the working LSP and protection LSP are not terminated at a same Egress LSR, but correspond to different Egress LSRs which greatly improves the security of the MPLS network.
