US 7,116,642 B2 · SONET/SDH data link administration and management

Abstract

A network management and administration system provisioning data links in an optical networking environment is provided. The network management and administration system makes use of connectivity information in establishing and monitoring data links. The connectivity information includes data link termination specifications. Data link termination specifications include port and channel specifications. Each port may have a channelized or an unchannelized configuration. A virtual channel having a data transport capacity substantially equal to that of a corresponding unchannelized port is defined therefor. The advantages include a standardized, concise and comprehensive provisioning and presentation of data links.

Claims7

Dependent claims

A method of visualizing Packet over SONET (PoS) links in a data communications network, the method comprising:

maintaining connectivity information between nodes in the form of a plurality of data link records, each data link record corresponding to one link and one port on one node, the data link records having the seine structure for channelized and unchannelized port types and the same structure for port-port, port-channel, and channel-channel connection types;
and
displaying PoS links of interest in a similar manner, regardless of the port type of ports bounding each PoS link and regardless of connection type of each link.

Dependencies are inferred from the claim text.
