Embodiment Construction
[0042] The present invention will be further described below in conjunction with accompanying drawing:
[0043] Such as figure 1 As shown, the method for the VPWS message in this embodiment to traverse the three-layer IP network includes:
[0044] When the user data packet enters the UNI entry of the VPWS network PE:
[0045] Step S101, the switching chip performs the first processing, sequentially encapsulates the PW label, special VLAN, special source MAC and special purpose MAC on the outside of the packet, and sends the packet to the FPGA;
[0046] Step S102, FPGA performs second processing after receiving the packet, stripping off the special VLAN, special source MAC and special purpose MAC, encapsulating the GRE header, source MAC and destination MAC in turn on the outside of the PW label, and sending the packet to the switching chip;
[0047] Step S103, the switching chip performs the third processing, according to the destination IP address in the GRE header, check t...
