(2) MSTP circuit series model
The MSTP circuit with PTN hops is typically simpler, with fewer routing nodes, and a more common model is shown in fig. 3.
For example, the input ports of the plurality of network elements include 1-1 port, 7-2 port, 5-2 port, 2-3 port, and 8-3 port, and the output ports include 8-1 port, 6-1 port, 3-1 port, 7-1 port, and 5-5 port.

(3) Three pseudowires, each carrying a segment of Tunnel.
Among the three networking modes, the mode (1) is most widely applied, 9 of the opened circuits are occupied, and the subsequent newly opened PTN circuits are mostly the mode, wherein a Tunnel carrying one pseudo wire corresponds to two routes which are respectively a working route and a protection route, and the mode is called a Tunnel protected PTN circuit;
the mode (2) has a duty ratio of 1 in the opened circuits, and the newly opened PTN circuit is rarely the mode, wherein two tunnels carrying two pseudo wires have only one route respectively, so that one of the two tunnels corresponds to a working route, and the other corresponds to a protection route, and the mode is called a PTN circuit protected by the pseudo wires;
mode (3) is one of modes (2), and it can be understood that two of three pseudowires are connected as one pseudowire in mode 2, and that this type is very few in the already-opened circuit.
The pseudo wire protection circuit has relatively complex serial connection flow, the pseudo wire of the circuit is segmented in the data in the library, one pseudo wire can be divided into a plurality of segments, each segment of pseudo wire also corresponds to one segment of Tunnel, and the Tunnel is protected by only one segment of pseudo wire and also corresponds to only one segment of Tunnel.

further, the routes of each segment of the sequenced tunnels are sequenced and combined with the routes of other tunnels;
then, the circuit service route is connected with the Tunnel route which is completed and combined according to the end A to end Z in the PTN circuit serial model, and the PTN whole route serial connection is completed;
and finally, judging whether the interconnection end circuit jumper connection relation exists between the A end and the Z end according to the port binding relation, and taking the circuit without the jumper connection relation as a local PTN circuit for warehousing processing.
According to the PTN circuit serial model, the invention completes the PTN circuit serial connection, and realizes unified resource management and data acquisition of the PTN circuit of the operator.
Based on any of the above embodiments, based on an MSTP circuit concatenation model, implementing MSTP circuit concatenation includes:
associating Channel data in the MSTP circuit serial model with logic Channel VCTrunc data, and filtering a Channel circuit associated with the VCTrunc data;
grouping the Channel circuits with the association based on the VCTrink data, wherein each group of Channel circuits corresponds to one MSTP circuit;
selecting one Channel circuit with earliest creation time in each group of Channel circuits as a reference Channel, and acquiring cross data associated with all the reference channels;

based on the corresponding relation between the VCTruk data and the Ethernet equipment, the MAC port information and the VLAN information are supplemented in the initial MSTP tandem circuit, and the complete MSTP tandem circuit is obtained.
Specifically, as shown in the logic branch on the right side in fig. 4, the MSTP circuit concatenation flow proposed by the present invention includes:
first, filtering channels associated with VCTruk exists, and obtaining routes related to the channels; grouping channels according to VCTruk associated with the channels, wherein each group of channels corresponds to one MSTP circuit;
selecting one Channel with earliest Channel creation time in each group as a reference Channel, acquiring cross data related to all the reference channels, performing cross-topology iterative concatenation on each reference Channel, and completing the concatenation of the routing nodes of the complete SDH equipment;
then iterating the group of channels, and sequentially filling all node time slots on each Channel to the routing nodes corresponding to the reference channels which have completed SDH concatenation to form an initial MSTP concatenation circuit;
finally, according to the corresponding relation between VCTruk and Ethernet service equipment, the relevant information such as MAC port and VLAN is supplemented, the route node concatenation of the complete circuit of MSTP circuit section is completed, and thus the complete MSTP concatenation circuit is obtained

Firstly, the premise is that the PTN subnetwork and the MSTP subnetwork respectively realize complete serial connection of the internal circuits of the subnetworks;
further judging whether the circuit has a jumper connection relation according to a preset cross-domain rule, such as a port binding relation, and if the jumper connection relation does not exist, the circuit is still used as a local circuit and cross-network serial connection is not performed;
further, for each sub-network circuit with a jump connection relationship, different sub-network circuits are jumped together according to a preset jump connection rule to obtain a PTN-MSTP circuit, and the PTN-MSTP circuit is subjected to warehouse entry processing.
