Table 1
In the embodiment, centralized Control is carried out to electric layer network and photosphere network by controller, specifically, controller can be SDN centralized controllers.Specific implementation process is as follows：
S301：Controller sets up electric layer planning table and photosphere planning table according to the business model of deterministic type.
In specific implementation process, because electric layer network does not have link circuit resource, controller needs are planned (before the t2 moment) according to the business model drive photosphere network of deterministic type in table 1 in advance, generate each list item in the optical layer connection of simulation, i.e., photosphere planning table as shown in table 2.Specifically, photosphere planning table can include traffic ID, source node, destination node, route, intersection, connection ID, incidence relation of photonic layer list item etc..Wherein, the routing information for routeing to pass through between source node and destination node, such as be to pass through E ', F ' between A '-E '-F '-B ', i.e. A ' to B ' from the route source node A ' to destination node B '.Cross means set up the communicating passage of connecting node and link where it on node, such as E ' 11 represent to set up on node E ' from A '-E ' to E ' and from E ' to E '-F ' communicating passage.Connection ID can identify connection, and such as 0x00b1 represents the connection between A '-B ', corresponding A '-B ' between source node, destination node, route, intersection etc..
Further, each list item in the electric layer link that controller is simulated according to the simulation optical layer connection generation of photosphere network, i.e., electric layer planning table as shown in table 3.Specifically, electric layer planning table can include traffic ID, source node, destination node, route, Linktype, link ID, incidence relation of photonic layer list item etc..Wherein, the routing information for routeing to pass through between source node and destination node, such as be A-B from the route source node A to destination node B.Linktype can use
