Embodiment 1

[0030] like figure 1 As shown, this embodiment proposes a method for implementing an end-to-end MPLS layer-2 leased line, the method comprising: receiving the first frame data, the first frame data including a data part and a first layer-2 header;

[0031] In front of the layer 2 header of the first frame data, an MPLS inner layer label, an MPLS outer layer label and a second layer 2 header are sequentially set to generate the second frame data;

[0032] Taking out the MPLS outer layer label of the second frame data, pressing a new MPLS label on the MPLS outer layer label of the second frame data and then reinserting it into the second frame data to generate the third frame data;

[0033] Determine the exit according to the MPLS inner layer label of the third frame data and the new MPLS outer layer label generated after pressing the new MPLS label;

[0034] The fourth frame composed of the MPLS inner layer label of the third frame data, the new MPLS outer layer label generate...

Embodiment 2

[0036] like figure 2 As shown, the present embodiment proposes another method for realizing an end-to-end MPLS layer 2 leased line, the method includes: receiving the first frame data, the first frame data including the data part, the first vlan header and the first two layer head;

[0037] In front of the layer 2 header of the first frame data, an MPLS inner layer label, an MPLS outer layer label and a second layer 2 header are sequentially set to generate the second frame data;

[0038] Taking out the MPLS outer layer label of the second frame data, pressing a new MPLS label on the MPLS outer layer label of the second frame data and then reinserting it into the second frame data to generate the third frame data;

[0039] Determine the exit according to the MPLS inner layer label of the third frame data and the new MPLS outer layer label generated after pressing the new MPLS label;

[0040] Update the first vlan header of the third frame data according to the MPLS inner la...

Embodiment 3

[0045] like image 3 As shown, this embodiment proposes a device for implementing an end-to-end MPLS layer 2 leased line, the device includes: a first programmable device, a second programmable device, and a third programmable device;

Abstract

An embodiment of the present invention provides a method for implementing an end-to-end MPLS layer-2 leased line, the method comprising: receiving the first frame data; sequentially setting the MPLS inner layer label, The MPLS outer label and the second two-layer header generate the second frame data; take out the MPLS outer label of the second frame data, push a new MPLS label on the MPLS outer label of the second frame data, and then Re-insert into the second frame data to generate a third frame of data, determine the exit and then remove the remaining The first frame data composed of the data part and the first layer-2 header is sent to the external network through the determined egress. The invention also provides a device and a computer program product for realizing the end-to-end MPLS two-layer dedicated line. The present invention can be applied to all network devices supporting P4 language, and has strong versatility.

Description

technical field [0001] The present invention relates to network transmission technology, in particular to a method, device and computer program product for realizing an end-to-end MPLS two-layer dedicated line. Background technique [0002] With the development of public cloud, private cloud and network technology, the original ASIC solution based on fixed functions cannot well adapt to the rapidly changing market demand. Solutions such as programmable FPGAs have enhanced the ability of designers to realize personalized functions, but too much system performance needs to be sacrificed. Neither solution satisfies the designers involved when it comes to meeting market requirements for forwarding efficiency and programmability. Contents of the invention [0003] In view of this, the embodiment of the present invention expects to provide a method, device and computer program product for implementing an end-to-end MPLS layer 2 private line, so as to solve the problem that the ...
