Embodiment
Below in conjunction with accompanying drawing the methods, devices and systems that E-Packet that the embodiment of the invention provides are described in detail.Following examples are possibility of the present invention, and its priority is not represented in putting in order of embodiment.
Embodiment one:
The embodiment of the invention provides a kind of method that E-Packets, and as shown in Figure 1, this method comprises:
101, receive the message that described first provider edge sends by the described first pseudo-line;
Configuration virtual private network on the second provider edge PE2, between the first provider edge PE1 and PE2, set up the first pseudo-line, between PE2 and the 3rd provider edge PE3, set up the second pseudo-line, PE2 is with the first pseudo-line, the signaling type of the second pseudo-line stores in the label mapping table, and be described Virtual Private Network configuration signal sign, described signaling is designated intercommunication or not intercommunication, signaling is designated intercommunication and represents intercommunication between signalings dissimilar in this Virtual Private Network, and signaling is designated not intercommunication and represents not intercommunication between signalings dissimilar in this Virtual Private Network.PE2 receives the message that PE1 sends over by the first pseudo-line.
102, obtain the signaling sign of the signaling type and the described Virtual Private Network of the described first pseudo-line, the second pseudo-line;
PE2 goes into the signaling type that the label mapping table obtains the described first pseudo-line, the second pseudo-line according to the label lookup of the described first pseudo-line, the second pseudo-line is described.And obtain the signaling sign of described Virtual Private Network, described signaling is designated between signalings dissimilar in the described Virtual Private Network of sign intercommunication or identifies not intercommunication between signalings dissimilar in the described Virtual Private Network.
103, when the signaling type of the first pseudo-line that is obtained different with the second pseudo-line signaling type, and the signaling of described Virtual Private Network is designated sign in the described Virtual Private Network between dissimilar signaling during intercommunication, transmits described message by described the 3rd provider edge of the described second pseudo-alignment.
Different with the second pseudo-line signaling type when the signaling type of the first pseudo-line that is obtained, and the signaling of described Virtual Private Network is designated sign in the described Virtual Private Network between dissimilar signaling during not intercommunication, abandons described message.
When the signaling type of the first pseudo-line that is obtained is identical with the second pseudo-line signaling type, whether PE2 E-Packets by the second pseudo-alignment PE3 according to existing rule decision, if that is: the second pseudo-line does not have level to cut apart, then PE2 E-Packets by the second pseudo-alignment PE3; If the second pseudo-line has level to cut apart, then dropping packets.
The method that E-Packets that the embodiment of the invention provides, second provider edge receives earlier the message that first provider edge sends by the first pseudo-line, whether transmits described message by second pseudo-alignment the 3rd provider edge according to the signaling sign decision of the signaling type of the described first pseudo-line, the second pseudo-line and the Virtual Private Network that disposed.If the signaling of described Virtual Private Network is designated intercommunication between signalings dissimilar in the described Virtual Private Network of sign, even the signaling type difference of the then described first pseudo-line, the second pseudo-line, second provider edge is also transmitted described message by described second pseudo-alignment the 3rd provider edge, realizes intercommunication thereby make between the signalings dissimilar in the same Virtual Private Network.

304, intercommunication between the dissimilar signalings of provider edge 2 configuration virtual private network 1, provider edge 2 is transmitted described message by pseudo-line 3 to provider edge 3.
If not intercommunication between the dissimilar signalings of provider edge 2 configuration virtual private network 1, then provider edge 2 is not transmitted described message to provider edge 3, abandons described message.
If pseudo-line 1 is identical with the signaling type that pseudo-line 3 is supported, provider edge 2 is after receiving the message that provider edge 1 sends over by pseudo-line 1, transmit according to existing rule, if pseudo-line 3 has level to cut apart (promptly not the message that sends over of forwarding router), then abandon described message, if pseudo-line 3 does not have level to cut apart, then send described message to provider edge 3 by pseudo-line 3.
Below in conjunction with Fig. 4 the method that E-Packets that the embodiment of the invention provides is described in detail, as shown in Figure 4, on provider edge PEn, disposed VPN1, PEn uses between LDP signaling and PE1, the PE2 and sets up PW1, PW2, and PEn uses between BGP signaling and PE3, the PE4 and sets up PW3, PW4.
If intercommunication between the interior dissimilar signaling of configuration VPN1, as shown in Figure 5, this method that E-Packets comprises:
501, provider edge n receives the message that provider edge 1 sends over by pseudo-line 1;
502, provider edge n goes into the label mapping table according to the label lookup of pseudo-line 1, pseudo-line 2, pseudo-line 3, pseudo-line 4, obtains the signaling type of pseudo-line 1, pseudo-line 2, pseudo-line 3, pseudo-line 4;
