A new breed of network intensive "e-science" applications are emerging that require a new perspective on how networks provide resources to the user. These e-science applications often have large raw capacity requirements (tens of gigabits/second) and require global reach. The discipline scientists expect this type of performance to be deterministic and repeatable, and available in conjunction with other resources such as sensors, instruments, computational clusters, storage arrays, and the like. The DRAGON project, an NSF funded testbed in the Washington DC metropolitan area, has been developing open source generalized multi-protocol label swapping (GMPLS) based service concepts that provide dedicated and deterministic network resources to the e-science application. Using the GMPLS control plane and DRAGON extensions, an entire "application specific topology" can be established in an automated fashion across administrative boundaries, across heterogeneous network technologies, and can be instantiated in seconds rather than weeks or months. This paper describes the technologies being developed by the DRAGON project and some of the ways application specific topologies are being applied to advanced networked applications.
