摘要： Methods and systems are provided for determining a shortest minimum regeneration path in an optical network. The method includes creating a virtual node at a source node, the source node communicatively coupled to a destination node through a plurality of nodes and links. The method includes traversing the virtual nodes, wherein traversing the virtual nodes comprises selecting an unvisited virtual node at a node; identifying a candidate virtual node from the unvisited virtual node; determining whether the candidate virtual node exceeds a maximum permitted weight; determining whether the candidate virtual node violates a shortest minimum regeneration path condition; and creating the new virtual node from the candidate virtual node if the candidate virtual node does not exceed the maximum permitted weight and if the candidate virtual node does not violate the shortest minimum regeneration path condition.

摘要： It is an object to provide a technique capable of using a single framer as a necessary framer and causing the framer to be shared among a plurality of transmission destinations and priorities when coping with a plurality of transmission destinations or priorities and a change in a bandwidth of a physical lane that is caused by a change in a modulation scheme or a change in the number of wavelengths.A multilane transmission device that allocates client signals based on a transmission destination or a priority, decides the number of virtual lanes necessary for transmission of the client signals allocated based on each transmission destination or each priority, allocates the client signals allocated based on each transmission destination or each priority to the virtual lanes whose number has been decided, and frames the client signals allocated to the virtual lanes as transport frames, multiplexes the virtual lanes into a physical lane, and transmits the framed transport frames by using the physical lane.

摘要： Techniques are described herein for enabling mapping of virtual lanes for data streams for transmission over an optical transport network (OTN). Line encoded data blocks of a first data stream are distributed at an endpoint device in an OTN. The line encoded data blocks of the first data stream are distributed across a plurality of second data streams such that the second data streams can be processed at a lower data rate than a data rate associated with the first data stream. A transcoding operation is performed on the data packets of each of the second data streams to generate transcoded data packets. The transcoded data packets are processed such that the transcoded data packets of each of the second data streams can be sent over the OTN at the lower data rate.

摘要： Additional bandwidth is provisioned to layer 2/3 networks by initially provisioning optical wavelength channels to meet incremental needs for additional capacity. When bandwidth requirements grow large enough, a wavelength-sized channel is provisioned to meet the bandwidth needs, and the previously provisioned optical wavelength channels are freed up to be reused for additional growth. The optical wavelength channels may be channelized VLANs mapped to resizable optical channel data units such as ODUflex units.
