Session initiation protocol (SIP) has potential to be selected as a control plane signaling protocol for delivering real-time multimedia applications in military networks. It is necessary to study behaviors of SIP and SIP-based real-time applications as well as to understand their limitations in a tactical network environment. The goals of this study are to assess SIP signaling protocol performance...
This paper discusses the need to achieve a consistent PHB across the GIG regardless of the link types. The paper shows an approach on how to create this consistent PHB, and uses the example when the hop is a multiple access waveform (e.g., JTRS) and when the hop is a COTS router followed by a satellite terminal. Creating this consistent PHB also considers bandwidth optimization and multi-level precedence...
The importance of tactical networks that support military operations is well known in the DoD community for their ability to rapidly deploy anywhere at anytime without pre-existing infrastructure. Tactical networks provide a battle space where warfighters possess dynamic and ad hoc mobile communications to support operations against a broad array of threats. Managing mobility to provide undisrupted...
A critical element of the all-IP architecture is IP multimedia subsystem (IMS). IMS is a maturing technology and has been standardized by wireless cellular industry. However, IMS was not designed and developed for using in military environments and supporting associated application services. Introducing IMS into futuristic military networks for supporting future combats has to face different challenges...
In a military communications environment, multiple communication links could exist between senders and receivers. This feature enhances communication connection reliability and throughput. Since each link may not use the same type of device or transmission method and links' characteristics may not be the same, sometimes, the link availability and link data rate could fluctuate significantly, which...
The mobile user objective system (MUOS) is DoD's next generation UHF SATCOM system. The MUOS design is based on the commercial 3G UMTS/WCDMA architecture. As a commercial architecture, UMTS is continually evolving to provide new and improved features and services to its customers. By leveraging this architecture and much of its associated ground components, MUOS may also be able to incorporate new...
In military networks, precedence and preemption (P&P) and quality of service (QoS) are both required. QoS refers to meeting the performance requirements of an application (packet delay, packet loss, packet delay variation, service availability, connection set up time, connection acceptance ratio, etc.) while P&P refers to meeting the QoS requirements of the highest importance applications...
