—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 a parallel shortest path-searching 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 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.
| We propose a bu®er management mechanism , called V-WFQ (Virtual Weighted Fair Queue-ing), for achieving approximately fair bandwidth allocation with a small hardware amount in high-speed networks. The basic process for allocating bandwidth fairly uses selective packet dropping to compare the measured input rate of the °ow with an estimated fair bandwidth(More)

Titers of anti-keratin antibodies (AKA) involving IgG and IgM fractions were determined by a solid-phase enzyme-linked immunosorbent assay (ELISA) and were found to be significantly higher on average in patients with pustulosis palmaris et plantaris (PPP) than in normal controls. Positive rates of IgG-AKA and IgM-AKA in sera of PPP patients were 50% and(More)
—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)
An overview is given of previously-proposed measurement-based connection admission control (CAC) methods. First we address requirements for CAC methods, and then provide a taxonomy for CAC methods. Measurement-based CAC methods are discussed in detail, classified according to the taxonomy, and compared against each other with respect to the requirements. We(More)
—We are proposing a new optical access network architecture using PLZT 10 nsec high-speed optical switches, called Active Optical Network (ActiON). Our architecture can increase four times the number of subscribers as well as double the distance between OLT and ONUs than GE-PON. Moreover, a user can establish secure communication in ActiON. Because ActiON(More)
