This letter proposes a disjoint path selection scheme for generalized multi-protocol label switching (GMPLS) networks with shared risk link group (SRLG) constraints. It is called the weighted-SRLG (WSRLG) scheme. It treats the number of SRLG members related to a link as part of the link cost when the -shortest path algorithm is executed. In WSRLG, a link… (More)
The rapid development of Asynchronous Transfer Mode technology in the last 10-15 years has stimulated renewed interest in the design and analysis of switching systems, leading to new ideas for system designs and new insights into the performance and evaluation of such systems. As ATM moves closer to realizing the vision of ubiquitous broadband ISDN… (More)
New energy efficient network design algorithm and tool for low power consumption named MIDORI is proposed. Network is used minimum set of nodes and links which can transfer all communication traffic under QoS restriction. QoS restrictions are included hop limit, bandwidth limit reliability and stability. Set-covered problem is applied to this algorithm and… (More)
This paper proposes a distributed virtual network topology (VNT) reconfiguration method for Internet protocol over wavelength-division-multiplexing network under dynamic traffic demand. We developed a simple heuristic algorithm for calculating the VNT for distributed control. Generalized multiprotocol label switching (GMPLS)-based routing protocol has been… (More)
This paper proposes high-energy efficient future-Internet architecture. All traffic is aggregated to a solitary universal cloud router through an optical aggregation network. Evaluation shows power consumption can be reduced to 1/1000 compare to present Internet.
The Internet is an extremely convenient network and has become one of the key infrastructures for daily life. However, it suffers from three serious problems; its structure does not suit traffic centralization, its power consumption is rapidly increasing, and its round-trip time (RTT) and delay jitter are large. This paper proposes an extremely energy… (More)
This paper proposes a parallel shortest pathsearching algorithm and implements it on a newly structured parallel reconfigurable processor, DAPDNA-2 (IPFlex Inc). Routing determines the shortest paths from the source to the ultimate destination through intermediate nodes. In Open Shortest Path First (OSPF), Dijkstra’s shortest path algorithm, which is the… (More)
This article proposes a network control method that realizes on-demand service providing in Elastic Lambda Aggregation Network (EλAN). EλAN is a next-generation access/aggregation network that provides various network services having different protocols and QoS requirements. EλAN also achieves the reduction of total network power consumption by sharing… (More)
The unified control of core / metro / access networks using Software-Defined Networking (SDN) is effective for providing services flexibly. In this paper, experimental results of the unified control by hierarchized Controller utilizing OpenFlow protocol and abstracted network are presented.
Machine-to-Machine (M2M) communication is expected to grow in networks of the future, where massive numbers of low cost, low function M2M terminals communicate in many-to-many manner in an extremely mobile and dynamic environment. We propose a network architecture called Data-centric Network (DCN) where communication is done using a data identifier (ID) and… (More)
