A mesh network architecture is disclosed whose protected services can be restored quickly after the failure of a network element (i.e., a network node, a network transmission facility). Furthermore, the protected services can be restored after all single and most multiple network-element failures as quickly as a ring network can recover from a single network-element failure. And still furthermore, the illustrative embodiment is also advantageous in that it can be administered and maintained, for most purposes, as a collection of distinct ring networks. Embodiments of the present invention can use any protocol or transmission technology (e.g., wavelength division multiplexing, SONET/SDH, ATM, etc.). Furthermore, embodiments of the present invention distinguish between the transport function, the provisioning function, and the fault notification functions of a network and provide that each of the functions can be accomplished by different networks using different protocols.

The invention provides methods and apparatus for characterizing complex polymeric mixture of interest. Candidate solutions are eliminated from a solution space using one or more experimental measurements of a polymeric mixture of interest. The elimination step can be repeated one or more times using different experimental measurements produced by various chemical and physical protocols, so that the remaining candidate solutions converge to describe the actual polymeric mixture under investigation. Once the composition of the complex polymeric mixture has been characterized, the information thus generated can be used to facilitate, for example, the manufacture of a bio-equivalent of the complex polymeric mixture.

A method of coherently provisioning one or more paths through a transport network is disclosed. In other words, none of the traffic paths are provisioned unless all of the traffic paths can be provisioned. All of the nodes in one or more transport networks are listed that must be configured to provision all of the proposed traffic paths, and all of the nodes are checked, one after another, to ensure that each node can, in fact, provide all of the resources needed to establish all of the proposed traffic paths before any of the traffic paths are actually provisioned. As each node is visited, the set-up message directs each node to reserve, but not actually provision, the resources to be provided by that node for all of the proposed traffic paths. When all of the nodes have been visited, the set-up message re-visits each node and directs each node to actually provision the resources that had been previously reserved.
