for\( {t}_{p,q}^{m,n} \)doInvoking the K algorithm in G^{L}(V^{L}, E^{L}) and calculate the shortest path from \( {v}_p^m \)to \( {v}_q^n \), then range the path according to its length: P = {p_{1}, p_{2}, …p_{k}, };for p_{k} ∈ P doIn this path, take the input node and output node of every domain regard as the source node and the sink node of a sub path in this domain. Produce the business requirements of every domain, and send them to the related controller; if All domain return OKPath creation successful, jump out; elsePath creation fail, the loop go on; end ifend forend for |
