Policy-based, on-demand provisioning of optical transport bandwidth is disclosed. In one of many possible embodiments, a system is provided for policy-based, on-demand provisioning of optical transport bandwidth. The system includes a layer-specific operation support subsystem (OSS) configured to manage network elements that form a sub-network over an optical transport network. The optical transport network provides bandwidth-on-demand provisioning capabilities. The layer-specific OSS includes one or more predefined bandwidth provisioning policies. The layer-specific OSS is configured to selectively request on-demand provisioning of bandwidth on the sub-network based on the predefined bandwidth provisioning policies.

The present disclosure relates to systems and methods for providing bandwidth-on-demand telecommunications services over next-generation optical transport networks (NG-OTN). One embodiment of a system providing bandwidth-on-demand services includes a next-generation optical transport network (NG-OTN) having an intelligent control plane (ICP) and new-generation synchronous optical network (NG-SONET) capabilities. A next-generation operation support subsystem (NG-OSS) is communicatively coupled to the NG-OTN. The NG-OTN and the NG-OSS are configured to provide the bandwidth-on-demand services.

摘要:
Management packets are defined that are modified in the payload by each node along a virtual connection and are used to measure both end-to-end QoS and specific individual intermediate node performance parameters. Management packets are implemented by defining entirely new packets or by modifying ATM OAM cells. Switches or routers for use as intermediate nodes are defined that modify the payload of the management packet and locally measure packet delay and packet loss. An intermediate node measures and records the difference between the arrival and departure times of management packets at that switch utilizing delay-stamp fields within the management packets and either the switch internal routing header or timestamp fields within the packet. At the endpoint of the virtual connection, delay-stamp fields in the management packet indicate individual node delays and the cumulative delay. An intermediate node counts the number of packets it discards and records these values in the payload of the management packet individually and cumulatively.

Method and apparatus for tracking, recording and distributing link state characteristics over communications networks. The invention allows network operators to efficiently define, track, store and disseminate link state characteristics using a bit-field-encoded resource record that is capable of representing many more link state characteristics than the bit-mask-encoded records used in existing systems. As a result, the present invention, when used in conjunction with standard routing and network maintenance algorithms, provides a much more efficient method than existing systems provide, for performing sophisticated networking tasks, such as handling complicated information transmission requests, setting up and tearing down network paths, and making dynamic routing decisions.

A system includes a plurality of resources. A network analysis device is configured to identify a shared risk between at least two of the resources. A method includes arranging a plurality of resources in a resource group, identifying, by at least one network analysis device, a shared risk between at least two of the plurality of resources, and assigning a shared risk identifier to each resource having the shared.

A network (10) includes a broadband customer service module (B-CSM) (20). The B-CSM (20) includes a plurality of feeder interface cards (FICs) (36) and optical line cards (OLCs) (38) which are coupled together through a midplane assembly (34) so that each FIC (36) couples to all OLCs (38) and each OLC (38) couples to all FICs (36) through junctor groups (68). A reference clock which oscillates at a frequency slower than the data rate is routed with payload data so that it receives delays similar to those imposed on the payload data due to processing. At second stage switching fabrics (50) where data need to be extracted from signals flowing within the B-CSM (20), a clock regeneration circuit (32) generates a master clock signal oscillating at twice the data rate and phase synchronized to a delayed reference clock. A geometric compensation scheme corrects for timing skew which occurs when clocks and data are distributed to points or small areas from widely dispersed locations, and when clocks and data are distributed from points or small areas to widely dispersed locations. The B-CSM (20) ranks the junctor groups (68) according to signal occupancy and manages signal traffic to efficiently utilize the FICs (36) and to reduce the probability of signal blocking. The junctor groups (68) can include a number of bidirectional junctors. The bidirectional junctors are configured to carry upstream or downstream signals according to current upstream and downstream signal traffic volume.
