چکیده انگلیسی

This article proposes a new fault location mechanism in optical network. In this mechanism, a network alarm packet format with time-stamp is introduced to implement fast restoration. In locating the fault, the existing schemes are usually complex and inaccessible when solving the multifailure location problem. For multifailures, the proposed mechanism using time-stamps is more efficient in locating the fault and decreasing computational complexity.

مقدمه انگلیسی

By 2000, wavelength division multiplexing (WDM) technology, which really improves the transmission capacity of a single fiber, has been applied substantially in backbone optical networks. One optical cable contains 8–64 fibers, and the number of fibers in transcontinental cables that use ribbon structure can reach several hundred. If four or more optical carrier signals are used in one fiber, this fiber can carry data information as many as T bit/s. Moreover, inexpensive devices such as semiconductor optical amplifier and wavelength converter also facilitate the rapid development of WDM technology.

نتیجه گیری انگلیسی

The mechanism proposed in this article can realize precise location of network faults. Its advantage depends on the structure of alarm packet using time-stamp. In this mechanism, the convergence time for judgments in manager will be shortened, and this will obtain higher speed for recovery in multifailure location. Hence, it can be concluded safely that the scheme proposed can be a good solution to fault location in optical network
