The invention provides an improved management of network devices in a communication network by extending the Simple Network Management Protocol (SNMP), which provides an effective identifying of the Management Client originating a request and sends rich textual status and error responses from the network device.

Method and system for improved management of a communication network by extending the simple network management protocol

Optical communication networks often incorporate fiber rings or fiber mesh topologies for interconnecting its nodes. Both of these topologies can contain closed optical loops at one or more wavelengths within the optical spectrum. In amplified optical systems, the inherent loss of these optical loops is counteracted by the amplifier gain. Thus, the optical loop may have a net loss that is too low to prevent excessive noise buildup resulting in a lasing fiber loop. The noise that builds up within such amplified systems is dominated by the Amplified Spontaneous Emission (ASE) noise resulting in ASE loops. Such loops can have a serious impact on all wavelengths carried by the fiber and lead to a partial or complete loss of end to end communication due to a severe degradation in signal to noise ratio. This invention provides an effective method and system for avoiding ASE loops in optical communication networks. The method deploys optical seams as well as a unique signature for a wavelength instance for achieving an effective solution that is resilient to errors and failures that may occur on the system both during service creation and normal operation.
