Abstract

Rapid progress in deployment of national and regional optical network infrastructures holds the promise to provide abundant, inexpensive bandwidth to scientific communities. The expectation is that this will provide a catalyst for innovation across a range of eScience applications. However, there remains considerable architecture and research work in order to allow such applications to access a common shared high-speed infrastructure efficiently and flexibly. This paper presents an experimental solution currently being designed and tested over the Dynamic Resource Allocation via GMPLS Optical Networks (DRAGON) and the Internet2 Hybrid Optical and Packet Infrastructure (HOPI). This implementation provides deterministic network services to high-end eScience applications in the form of Ethernet “circuits” using GMPLS to dynamically provision user specific VLAN based configurations. This requires addressing several research issues associated with multi-layer networks, interdomain routing, signaling, and multi-constraint path computation. The larger vision is that of a shared infrastructure consisting of multiple network technology layers over which an intelligent control plane can provide for a unified service model. The instantiation described here of Ethernet over WDM provides an ideal platform for both experimental research and, real services, and a migration path to a production infrastructure.

Abstract

Emerging network applications tend to be built over heterogeneous network resources spanning multiple management domains. Many such applications have dynamic demands for dedicated, deterministic, highbandwidth connections. The Generalized Multi-Protocol Label Switching (GMPLS) networks under development can address these kinds of demands by using policy-based resource management and service provisioning technologies. In this paper, we present the architecture and implementation for policy-based resource management and service provisioning as part of the work on the NSF funded Dynamic Resource Allocation via GMPLS Optical Networks (DRAGON) Project. This work captures several critical features of service-oriented GMPLS networks, including a) collaborative interdomain resource management; b) interdomain end-to-end path computation; c) advance scheduled provisioning; and d) Authentication, Authorization and Accounting (AAA). These features rely on the capability of exchanging and coordinating resource and policy information among multiple participating domains. In pursuit of this capability, we propose a three-dimensional (3D) Resource Computation Model (RCM). The three broad dimensions of this model are Traffic Engineering (TE) constraints, time schedule constraints, and AAA policy constraints. The 3D RCM facilitates policy based resource allocation based on many specific constraints within these three broad categories. Based on this model we describe our approach to GMPLS interdomain end-to-end path computation, advance scheduled provisioning, and AAA policy based provisioning, respectively. Our current DRAGON implementation status is also reported in this paper.
