The restoration time in high capacity optical networks has to be kept as short as possible in order to avoid a huge loss of data. This paper discusses several methods to improve restoration time in optical networks and we propose the use of error codes that will trigger immediately the appropriate layer recovery mechanism, which is the best to handle a given fault.

Abstract:In this paper we present a mechanism for obtaining an abstraction of network topology in optical networks in order to compute an end-to-end lightpath across multiple domains.

The restoration time in high capacity optical networks has to be kept as short as possible in order to avoid a huge loss of data. This paper discusses several methods to improve restoration time in optical networks and we propose mechanisms of implementing such inter-layer communication in order to decrease restoration time for a 10Gigabit Ethernet based network.
