摘要： The present invention discloses novel network architectures for evolving traditional service provider networks. The network architecture of the invention has a transport layer including an optical network. At least one node of the network architecture includes a large packet switch that is coupled to the transport layer and to an access layer. The large packet switch aggregates a plurality of services from the access layer. The large packet switch also performs packet level grooming of the information from the services prior to transport of the information via the transport layer. The optical network performs restoration for the network architecture. In one embodiment, the optical network is an optical ring network including at least one optical switch and restoration is performed at the layer-0 (optical layer). In another embodiment, the optical network is a bi-directional line-switched ring (BLSR) utilizing a Synchronous Optical Network (SONET) standard and restoration is performed by the layer-1 (SONET layer). The network architectures of the invention by utilizing a large packet switch to perform service aggregation and packet level grooming, and by performing restoration either at the layer-0 (optical layer) or layer-1 (SONET layer), creates a single converged network that achieves the superior restoration performance needed for carrier grade availability but at much lower costs than traditional service providers which operate multiple overlay networks. Also disclosed are methods to optimize traditional service provider networks and the disclosed novel architectures of the invention.

摘要： A method, apparatus, and computer program product for dynamic bandwidth allocation in a packet switched network having a ring architecture is disclosed. The method includes monitoring an occurrence of a contention of resources at a participating node and its neighboring nodes on the network. In response to a monitored occurrence of the contention of resources, bandwidth is dynamically allocated according to a fairness algorithm. Dynamically allocating bandwidth resolves contention of resources in a fair manner within given fairness constraints while enabling a prescribed maximum utilization of available bandwidth between the nodes. Lastly, the fairness algorithm generates fairness criteria in response to states that are local to the participating node and states obtained from the neighboring nodes.
