Different types of service channels encapsulate different service heads when service encapsulation is performed. The common two-layer L2 network can encapsulate the L2 header, the Internet protocol IP network can encapsulate the IP header, the multiprotocol label switching MPLS network can encapsulate the MPLS header, etc., the IP header can be encapsulated and decapsulated by the switching chip, and if the switching chip is not supported, the IP header can also be encapsulated and decapsulated by the FPGA, etc.
As an optional embodiment of the present embodiment, the present optional embodiment further optimizes determining the service header information according to the service channel as: when the service channel is an internet protocol network or a multiprotocol label switching network, the source physical address and the destination physical address in the service header information are determined according to the physical address of the local machine.
When the service channel is an internet protocol network (i.e. IP network) or a multiprotocol label switching network (i.e. MPLS network), the physical address of the local machine is determined, the physical address of the local machine is used as a source physical address and a destination physical address in the service header information, and the source physical address and the destination physical address are written into the service header to complete service encapsulation. Other types of information may also be included in the traffic header information.
Illustratively, the process of determining the service header information is described using the service channel as an internet protocol network. The following MAC address is a physical address, the routing MAC address of the device R1 is MAC1, the routing MAC address of the device R2 is MAC2, the device R1 is connected to the device R2 through an IP network, and the IP address IP1 on the device R1 and the IP address IP2 on the device R2 are reachable through routing. When the device R1 is used as a local device and the device R2 is used as a device corresponding to the outlet end, an IP header can be added outside the stacking header of the devices R1 and R2, the IP header information (service header information) added outside the stacking header of the devices R1 and R2 is the source IP address IP1, the destination IP address IP2, and both the source MAC and the destination MAC are MAC1. When the device R2 is used as a local device and the device R1 is used as a device corresponding to the outlet end, the source IP address in the added IP header information from the device R2 to the device R1 is IP2, the destination IP address is IP1, and both the source MAC and the destination MAC are MAC2. And after the service header encapsulation is finished according to the service header information, obtaining an encapsulated message, re-entering the service processing in the entering direction, namely determining an outlet port of the encapsulated message according to the service table, and sending the message according to the outlet port. Because the destination MAC in the service header information of the service header is the local route MAC, the service header information enters an IP route table (namely a service table) to be searched, and is forwarded according to the IP route table. Therefore, the stacked message is sent through the service table, and the multiplexing service channel realizes the cross-network stacking.
By way of example, the procedure for determining the header information will be described using a service channel as an example of a multiprotocol label switching network. The routing physical address (MAC address) of the device R1 is MAC1, and the routing MAC address of the device R2 is MAC2.

When the device 31 is used as a local device and the device 32 is used as a device corresponding to an outlet end, an MPLS header can be added outside a stacking header of the device 31 to the device 32, and both a source MAC and a target MAC in MPLS header information (namely service header information) are MAC1 and MPLS LABLE is 100; when the device 32 is used as a local device and the device 31 is used as a device corresponding to an outlet end, both a source MAC and a destination MAC in MPLS header information added from the device 31 to the device 32 are MAC2, and MPLS LABLE is 600. And after the service header encapsulation is finished according to the service header information, obtaining an encapsulated message, re-entering the service processing in the entering direction, namely determining an outlet port of the encapsulated message according to the service table, and sending the message according to the outlet port. Because the destination MAC in the service header information of the service header is the local route MAC, the service header information enters an MPLS table (namely a service table) to search and is forwarded according to the MPLS route table.

And writing the service header information into the service header. The service header information may also include information of a physical address.
Illustratively, the process of determining the service header information is described using a service channel as a two-layer network. The bridge MAC address of the device R1 is MAC1, the bridge MAC address of the device R2 is MAC2, the device R1 and the device R2 are connected in the VLAN100 through an L2 network for communication forwarding, a two-layer header can be added outside a stacking header of the device R1 to the device R2, the device R1 is taken as a local device, when the device R2 is taken as a device corresponding to an outlet end, the source MAC is MAC1, the destination MAC is MAC2 and the VLAN is 100 in L2 header information (service header information) added outside a stacking message header of the device R1 to the device R2; when the device R1 is used as a local device and the device R2 is used as a device corresponding to the outlet end, the source MAC in the L2 header added from the device R2 to the device R1 is MAC1, the destination MAC is MAC2, and the VLAN is 100. And after the service header encapsulation is finished according to the service header information, obtaining an encapsulated message, re-entering the service processing in the entering direction, namely determining an outlet port of the encapsulated message according to the service table, and sending the message according to the outlet port. Forwarding is performed by looking up a MAC table (traffic table) within VLAN 100.
