| Currently implemented traditional Quality of Service (QoS) schemes such as the DiffServ services require that all routers in the user data path be configured with the same traffic management policies prior to the flow of the data, implying some coordination effort must have been performed up front. The routers must locally store these policies in order to achieve consistent service treatment of the user data end-to-end. Incoming data with a matching service “tag” are queued and scheduled for transmission according to these locally stored policies. The required traffic management policies can be distributed to the routers in non-real-time using configuration via the network management plane or in semi-real-time using signaling via the control plane. For airborne networks, it may be desirable to have an alternative QoS scheme that does not require traffic management policies be disseminated to and stored at all routers in the data path yet which can still provide guaranteed QoS services compatible with those of traditional QoS schemes. We propose and assess the performance of such a QoS scheme for its operational suitability to the airborne network. The evaluation also assesses the means by which the new QoS scheme in the airborne network seamlessly integrates with QoS scheme in other networks comprising the GIG in accordance with policies from the DISA QoS Working Group. We present our simulation results and assessment in the context of operational scenarios that reflect airborne operations with the results showing that our proposed QoS scheme can provide the needed QoS services without the cumbersome traffic management policy coordination and configuration to all routers in the network. | |||
| Mr. Phong Khuu has over 16 years of experience in systems engineering and network protocol design and development. Currently, Mr. Khuu is a Technical Lead for the Wireless Network Team at BAE Systems – Network Enabled Systems (NES) in Reston, Virginia. Mr. Khuu started his career in 1991 with a private data communication company developing control and management firmware for analog modems. In 1994 he joined Broadband Technologies which later became BoschTelecom, Inc. and eventually Marconi. In 2000, Mr. Khuu left Marconi and joined Turin Networks, a startup company specialized in multi-service aggregation and switching transport systems. In 2004, Mr. Khuu joined BAE Systems - NES. While at Marconi, Mr. Khuu worked on various broadband delivery systems for the residential application such as the Video-on-Demand and Video Broadcast systems utilizing Asymmetric Digital Subscriber Line (ADSL) and very high bit rate DSL (VDSL) and Asynchronous Transfer Mode (ATM) technologies. While at Turin Networks, he worked on systems design of a multi-service aggregation and switching transport system (SONET/SDH, DCS, Ethernet, and ATM) and a traffic management processor customized to support packets, frames, and (ATM) cells. He also represented Turin’s and Marconi’s interests at the ATM Forum and DSL Forum. Currently, Mr. Khuu provides leadership in the architecture design, technical requirements, and implementation with a focus on quality of service (QoS) and routing issues for various mobile ad-hoc networks (MANETs) and programs such as the Joint Tactical Radio Systems (JTRS) networks, 802.16, and Future Combat System (FCS) Ground Mobile Radio (GMR). Mr. Khuu holds a B.S.E.E from Portland State University and an M.S.E.E. from North Carolina State University. | |||
