This paper proposes the use of service-oriented architecture and Web service technology, to address the current energy control problem. We propose a extended hierarchical model to organize the integrated smart grid system connected over the IP cloud, so that coordination and cooperation of all information systems are achieved autonomously and provides consumers with a carbon network management platform...
In WDM network, the load balance problem has received much attention in parallel and distributed applications because good solutions are critical to achieving speedups. This paper discusses traffic technology and load balancing in optical networks. In WDM network, enhancing the performance of an operational network, at both the traffic and the resource levels, are major objectives of traffic engineering...
In this paper, we discuss the routing technology, and analyze the switching technology in optical communication network. WDM optical systems provide orders of magnitude increases in the bandwidth that can be delivered over an existing fiber plant, and enable a significant time-to-market improvement in service delivery, compared to the alternative of laying additional fiber to provide more bandwidth...
The success of Generalized Multi-protocol Label Switching (GMPLS) provides a solution that enhances IP by its remarkably advanced features particularly the improvement in data transfer rate. GMPLS can be well classified, managed and policed across different types of networks. In this paper, we discuss the GMPLS and its application for core optical network.

In the optimization of operational networks the most important target is the minimization of congestion. Congestion can be divided into two types, congestion in the case where resources are insufficient to carry all the traffic, and congestion in the case where resources are divided inefficiently so that a part of the network is over-utilized while another part of the network has unused band-width...
In recent years, IP over WDM has become a key technology of choice for meeting the tremendous bandwidth demand in the optical infrastructure. Survivability is an emerging discipline that blends optical network security with business risk management for the purpose of protecting highly distributed information services and assets. No system is totally immune to attacks, accidents, or failures. Therefore,...
The popularity of the Internet and its related services continues to be one of the main reasons for the explosive growth of traffic volume in global information and optical network. This paper presents an analytical approach for studying load and traffic engineering (TE) in optical network. Load balancing is common in optical networks. It is a key component of traffic engineering, link bundling, and...
This paper proposes a new approach for wavelength-routed optical network with GMPLS technology in WDM networks. Wavelength-routed optical network is utilized through the wavelength-division multiplexing (WDM) technology which supports the propagation of multiple laser beams through a single fiber-optic link provided that each laser beam uses a distinct optical wavelength. Multi-protocol label switch...
In recent years, there have been dramatic changes in the character of security problems, in their technical and business contexts, and in the goals and purposes of their stakeholders. As a consequence, many of the assumptions underlying traditional security technologies are no longer valid. Failure to recognize the depth and breadth of these changes in combination prevents effective solutions to modern...
Generalized multi-protocol label switching (GMPLS) is being developed by the IETF as the industry standard for transport network control planes. GMPLS defines IP based control of optical resources. Routers are expected to deliver advanced services at higher throughput while handling large amounts of label switching path (LSP) creation/deletion, traffic engineering link information exchange, and link...

This paper proposes a protection scheme for the WDM network. The emergence of WDM technology has provided an unprecedented opportunity to dramatically increase the bandwidth capacity of telecommunications networks. In protection schemes, there are spare resources reserved for each protected part while those resources are not used under normal conditions. So restoration usually has better resource...
