| Abstract(in English) | Since the advance of SDN technology, network virtualization mechanisms for telecommunication carriers have been integrated to assign network resources flexibly to service providers. In these mechanisms, telecommunication carriers can reduce network costs by optimizing the resource assignment. This paper assumes that service providers demand a sequential traffic from these carriers, who are assigning it a shortest path sequentially in the network. Since the network link capacity is finite, some traffic cannot be assigned a shortest path at some point in time. At this point, we can try to assign the traffic a path (which is not shortest) by reconfiguring all the already embedded paths. However, the reconfiguration is time-consuming. To solve this problem, this paper proposes reconfiguring only partial paths which are selected according to the proposed algorithms. This paper evaluates the number of embedded paths, computational time, changing the algorithms of selecting paths in the reconfiguration and shows that restricting paths in the reconfiguration is effective. |
