Full-scale IT introduction in the near future is expected to increase information flows vastly and this information explosion will also increase the number of IT devices in use, positioning the energy consumption of IT devices themselves as a key issue. Most of conventional measures to treat energy consumption handle servers and network devices separately. This paper first identifies that the network...
In all-IP networks where all types of services are integrated using IP technology, it is highly likely that traffic congestion in one service causes congestion in other services, or that abnormal traffic in one service degrades the quality of other services. This paper proposes a flexible reallocation of both computing and network resource between services, in order to reduce the chance of congestion...
The use of RFID tag which identifies a thing and an object will be expanded with progress of ubiquitous society, and it is supposed that the various RFID-based services will be provided in the near future. Therefore, it is necessary to study how to construct RFID network system as a social infrastructure like the Internet. This paper proposes the virtualization method of RFID tag network system to...
All-IP networks, including next generation networks (NGNs), in which IP technology is used to integrate all services, are being studied or introduced in earnest worldwide. To support any services in all-IP networks, it is necessary to allocate both the computing resource (processing ability) and the network resource (bandwidth) simultaneously. This paper discusses congestion control schemes for all-IP...
Streaming media distribution services has been spreading rapidly, in which users view movies and music programs delivered over IP-based networks. In IP-based networks where resources are shared but cannot be reserved, it is difficult to prevent temporary congestion from occurring. Therefore, when temporary network congestion occurs, some packets will be discarded, resulting in the deterioration in...
In all-IP networks including NGN, both computing and network resources are required to be allocated simultaneously to each service request. The authors proposed optimal joint resource allocation methods for multiple resource types. Although those methods can achieve an efficient use of resources, it may result in an dasiaunfairpsila use of resources in which resources may be monopolized by a specific...
In computer networks including the next generation network (NGN), both computing and network resources are required to be allocated simultaneously to each service request. It is possible to improve the efficiency of resource use if we delay the start of resource allocation rather than rejecting the request if required resources arc not available when the request occurs. This paper assumes that both...
Multi-protocol label switching (MPLS) had been deployed by many data networking service providers because of its undeniable potential in terms of virtual private network (VPN) management, traffic engineering, etc. In MPLS networks, IP packets are transmitted along a Label Switched Path (LSP) established between edge nodes. To improve the efficiency of resource use in MPLS networks, it is essential...
