The transmission of IP packets over WDM technology (IP-over-WDM) is expected to be the basic transmission framework of the next generation network. In this paper, a novel architecture of optical network is presented. The optical network control plane is responsible for tracking the network topology and the state of network resources, and for establishing, removing and maintaining connections. These...
Wavelength-division multiplexing (WDM) is the best technology currently available to handle the rapidly increasing demand for bandwidth in fiber-optical telecommunications networks. This paper analyzes WDM transport network and discusses GMPLS technology for WDM network. Today, WDM optical transport networks have become more complex over the years and have extended into the metropolitan areas closer...
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...
Protection and survivability are very important problems in optical network. With the rapid development of WDM optical network, protection technology is paid more and more attentions. In this paper, we analyze the protection principle of WDM optical network, propose a protection method for optical network. Protection schemes can be divided into link protection, path protection, and partial path protection...
Optical systems nowadays provide the basis for cost-effective transmission of large amounts of bandwidth over the Internet, and will enable its future growth and the spreading of new applications and services. WDM wavelength multiplexing technology is the newest technology which minimizes the costs. WDM generates multiple "virtual fibers" in the current fiber cable infrastructures and makes...
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...
