And performing service header encapsulation on the target message, writing the service header information into the service header to form an encapsulated message, and completing service encapsulation. The function of forwarding the stacked message according to the service is further realized by performing service encapsulation on the stacked message.
Different types of service channels encapsulate different service headers when performing service encapsulation. A common two-layer L2 network may encapsulate an L2 header, an internet protocol IP network may encapsulate an IP header, a multiprotocol label switching MPLS network may encapsulate an MPLS header, and the like, and may be encapsulated and decapsulated by a switch chip, or may be encapsulated and decapsulated by an FPGA, and the like, if the switch chip does not support the MPLS header.
As an optional embodiment of this embodiment, this optional embodiment further optimizes determining the service header information according to the service channel as follows: when the service channel is an internet protocol network or a multi-protocol 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. an IP network) or a multi-protocol label switching network (i.e. an MPLS network), the physical address of the local machine is determined, and the physical address of the local machine is used as a source physical address and a destination physical address in service header information and written into a service header to complete service encapsulation. Other types of information may also be included in the service header information.
Exemplarily, the service channel is taken as an internet protocol network as an example, and the determination process of the service header information is described. The MAC address described below 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 and the device R2 are connected via an IP network, and the IP address IP1 on the device R1 and the IP address IP2 on the device R2 are reachable via a route. When the device R1 is used as a local device and the device R2 is used as a device corresponding to an egress end, an IP header may be added outside the stack header of the device R1 to the device R2, the IP header information (service header information) added outside the stack packet header of the device R1 to the device R2 is that the source IP address is IP1, the destination IP address is IP2, and both the source MAC and the destination MAC are MAC 1. When the device R2 is used as a local device and the device R1 is used as a device corresponding to the egress side, the source IP address is IP2, the destination IP address is IP1, and the source MAC and the destination MAC are both MAC2 in the information of the IP header added from the device R2 to the device R1. And after the service header is packaged according to the service header information, obtaining a packaged message, re-entering the service processing in the incoming direction, namely determining an output port of the packaged message according to the service table, and sending the message according to the output port. Because the destination MAC in the service header information of the service header is the routing MAC of the local device, the service header enters an IP routing table (namely the service table) for searching and is forwarded according to the IP routing table. Therefore, the stacked message is sent through the service table, and the cross-network stacking is realized by multiplexing the service channels.
The service channel is taken as an example of a multi-protocol label switching network, and the determination process of the service header information is described. The routing physical address (MAC address) of the device R1 is MAC1, and the routing MAC address of the device R2 is MAC 2. Fig. 3 is a schematic diagram illustrating that a link between devices may be reached when the device R1 and the device R2 are connected through an MPLS network, where when the device 31 communicates with the device 32, a message is sent from the device 31 to the device 34, sent to the device 33 by the device 34, and forwarded to the device 32 through the device 34, and links between devices are as shown in fig. 3. When the device 31 is used as a local device and the device 32 is used as a device corresponding to an egress end, an MPLS header may be added outside a stack header from the device 31 to the device 32, where a source MAC and a target MAC in MPLS header information (i.e., service header information) are both MAC1 and MPLS link is 100; when the device 32 is used as a local device and the device 31 is used as a device corresponding to an egress port, the source MAC and the destination MAC in the MPLS header information added from the device 31 to the device 32 are both MAC2, and MPLS link is 600. And after completing service header encapsulation according to the service header information, obtaining an encapsulated message, reentering service processing in the incoming direction, namely determining an outgoing port of the encapsulated message according to a service table, and sending the message according to the outgoing port. Because the destination MAC in the service header information of the service header is the routing MAC of the local machine, the service header enters an MPLS (multiple protocol Label switching) table (namely a service table) to be searched, and the forwarding is carried out according to the MPLS routing table.
When the service channel is a two-layer network, determining a virtual local area network port between the local machine and the device corresponding to the output port, and determining service header information according to the virtual local area network port. And writing the service header information into the service header. The service header information may also include information of physical addresses.
For example, taking a service channel as a two-layer network as an example, a process of determining service header information is described. A bridge MAC address of the device R1 is MAC1, a 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 forwarding, a two-layer header may be added outside a stack header of the device R1 to the device R2, the device R1 is used as a local device, and when the device R2 is used as a device corresponding to an egress end, a source MAC is MAC1, a destination MAC is MAC2, and a VLAN is 100 in L2 header information (service header information) added outside a stack packet header of the device R1 to the device R2; when the device R1 is a local device and the device R2 is a device corresponding to an egress port, the source MAC, the destination MAC, and the VLAN of the L2 header added from the device R2 to the device R1 are MAC1, MAC2, and 100, respectively. And after the service header is packaged according to the service header information, obtaining a packaged message, re-entering the service processing in the incoming direction, namely determining an output port of the packaged message according to the service table, and sending the message according to the output port. Forwarding is performed by looking up the MAC table (traffic table) within VLAN 100.
S211, determining the information of the target service message according to the encapsulation message.
In this embodiment, the target service packet information may be specifically understood as related information for service forwarding in the encapsulation packet. And determining target service message information stored in a service header of the encapsulated message by analyzing the encapsulated message.
S212, determining an output port according to the target service message information and a predetermined service table.
And searching a service table according to the target service message information, determining an output port corresponding to the target service message information, and further sending the message according to the output port.
And S213, taking the encapsulated message as a new message to be processed, and returning to execute S206.
The embodiment of the application provides a method for processing stacked data, which solves the problem that a fixed stacking port is required to be appointed when stacked messages are processed by a stacking device, determines an output port according to the messages to be processed when the messages to be processed are received, judges whether the device corresponding to the output port is the stacking device or not, judges whether the messages to be processed contain stacking encapsulation or not if the devices are stacked data, directly sends the messages to be processed containing the stacking encapsulation, stacks and packages the messages to be processed without the stacking encapsulation to obtain the encapsulated messages, wherein the encapsulated messages contain a stacking head and a service head, and searches the output port of the encapsulated messages according to a service table, thereby realizing the forwarding of the messages of the stacking type through a service channel, the stacking device does not need to appoint the fixed stacking port in the application, and packages the messages forwarded to the stacking device, and forwarding is carried out through the service table, and cross-network stacking is realized through multiplexing the service channels.
