This paper presents a method of Path Optimizing Strategy(POS) to solve the phenomenon of long routing, which is existing in Mobile Ad Hoc Network(MANET) of AODV routing protocol.

Optical fiber self-healing network based on wavelength routing of fiber gratings;

In this article, the difference between WBS and traditional wavelength routing is given and two types of multi-granularity optical cross-connect (MG-OXC) architectures are analyzed.

Due to the application of the WDM technology, wavelength routing network have several times of capacity as normal single wavelength network, and with routing by wavelength, the efficiency of lightwave in such network is mush higher than that in broadcast-select network.

The algorithm involves the topology of RPR network and the information of resource usage, makes full use of the static request information, considers carefully routing cost and corresponding routing length.

Design and implementation of DWDM wavelength router network control and management system

By designing the input and the output side of the flat focal field AWG symmetrically,a new-type AWG wavelength router with both flat input field and flat focal field is obtained.

Then, by explaining that the optical "micro electro-mechanical systems (MEMS)" would be the best devices, the paper describes their applications in wavelength routers, in optical crossconnects, and in optical switching successively.
