QoS-aware video streaming is demonstrated on an optical network using a service-oriented architecture and a NetFPGA-based optical control plane. Dynamic optical power fluctuations are either compensated or the lightpath is rerouted to ensure the QoS.
Quality-of-service aware packet protection is demonstrated using cross-layer signaling from a delay-line-interferometer-assisted optical-signal-to-noise-ratio monitor. 8??10 Gb/s wavelength-striped optical messages are successfully rerouted based on performance monitoring measurements communicated between the physical and networking layers.
To fully utilize radio resources by intelligently filling in as much radio spectrum gaps as possible, the concept of cognitive radio network has been well accepted. A challenge inherent in this technology is how to build a mechanism that can allocate resource by learning and adapting to a specific radio transmission environment. In this paper, we propose a cognitive resource management scheme that...
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...
With ever increasing mobility of the workforce and of the communication infrastructure itself, we will continue to see the growth in diversity of network domains and diversity of applications. The global information grid (GIG) is a prime example of such a networking environment. In most networking scenarios, the component network domains are owned and operated by different organizations. This paper...
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...
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...
