Scaling Quality of Service

Overview:

The emergence of real-time sensor rich and distributed command/control environments has placed an exclamation point on the distinct lack of practical end-to-end Quality of Service (QoS? ). The de facto compromise of overprovisioning is becoming increasingly untenable as new data sources and applications continually erode network capacity. Although significant research has been conducted on QoS? , the notion of dominant approach to end-to-end (E2E? ) QoS? remains elusive. Beyond deployment obstacles, a significant portion of issues with QoS? can be directly traced to the complex and often slow per-hop or per-domain resource negotitation procedures, often justified through amortization over the cost of long-term bulk data flows (ex. FTP). The goal of this research is to make significant strides in practical end-to-end QoS? with special consideration for the highly variable and mobile nature of the tactical network. The research leverages the group's recent work on Edge-centric Resource Management (ERM) and the group's work on the on-going DARPA TCP/IP Control Plane efforts to deliver expedited and effective mechanisms that dramatically simplify and streamline end-to-end QoS? . The end result of the research will be a much more robust and flexible network, practically achievable without a clean slate design.
