Admission control of applications into each service class based on the bandwidth capacity allocated to each service class and its particular QoS objectives that sufficiently adapt to the dynamic state of the underlying network which could be a highly mobile ad-hoc network in a lossy wireless environment. In this paper, we discuss empirical, analytical and simulation-based performance studies for an integrated IP QoS architecture implementing QoS resource management over a heterogeneous wireless and wireline network. The intearated IP 00s architecture is based on Assured Forwarding (class-based) Differentiated Services andThe very early design and implementation specifics of our admission control of individual flows into each service integrated IP QoS architecture are discussed in [5], [6]. class by a centralized server, called the Bandwidth BrokerThere have been significant modifications to the (BB) managing the network. The results we present in this architecture to support multi-class services and ad hoc paper are used as guidelines in designing the capacity wireless environments, which we will detail in an estimation algorithm for admission control and optimizing upcoming publication. QoS resource management within our integrated IP QoS architecture. These results serve as an instrument to understanding how to perform effective QoS resource management, using class-based differentiated services and admission control to guarantee class-appropriate end-toend QoS over IP networks.
TheIntegrated Networking Technology prototype demonstrates the capability of several emerging networking technologies to operate together seamlessly to enhance the network services targeted for dynamic mobile environments such as those found in the battlefield. The prototype consists of four technologies: 1) Autoconfiguration technology supports autonomous and rapid network deployment and configuration; 2 ) Self-Managed Virtual Network (SMVN) technology provides virtual networking capabilities for networks which do not natively support these functions; 3) Integrated Mobility Management technology supports session continuity in the presence of node mobility; 4) Assured IP Quality of Service (QoS) technology supports service quality guarantees for mission-critical applications.The prototype is capable of operating over the various types of equipment and protocols to be utilized in battlefield networks. The prototype is designed such that network services and functions are survivable and reconfigurable. In this paper, we describe the four technologies as well as the integrated prototype in the laboratory environment.
The CECOM MOSAIC ATD 1 encompasses an integrated set of diverse technologies to demonstrate rapidly deployable, secure, robust, assured-QoS communications among mobile ad hoc nodes. The Assured IP QoS technology solution integrates DiffServ based QoS resource management with centralized admission control over a dynamic tactical network environment. We describe an outdoor demonstration of our QoS technology prototype over an on-the-move MANET running OLSR. This demonstration does not include IP mobility support, however provides an alternate route between the ad hoc nodes through the use of two distinct wireless networks. The demonstration exhibits route changes between single and multiple IP hops as the nodes drive, and shows handoff between wireless networks as they move out of range of one radio network to the other. We summarize our observations and empirical performance results for real-time traffic.
