    • Without using additional probing packets, estimates of the narrow link bandwidth and available bandwidth of a network path are computed based on existing traffic. The network can be of different types such as a wireless battlefield network context or a wired or wireless commercial network environment. “Fast packets”, i.e. those packets which do not experience any queuing delay in the network, are identified. Fast packets are identified to resolve end-to-end packet delay into its constituent components (deterministic, transmission and queuing delays), estimate path utilization and eliminate the uncertainty (false alarms) that causes the prior art method to lose its effectiveness. An estimation algorithm computes end-to-end transmission delay and end-to-end deterministic delay of fast packets traveling along a path in a network. Examples of deterministic delay include satellite propagation delays and clock effects. Then, based on the results of the fast packet identifying algorithm, two logic branches are followed. A first branch calculates utilization and a second branch calculates narrow link bandwidth. The narrow link bandwidth is determined from the packet pair dispersion. The available bandwidth is obtained from the narrow link bandwidth and the utilization. Estimation of available bandwidth for an end-to-end network path allows traffic sources to judiciously regulate the volume of application traffic injected into the network.
    • 在不使用附加探测分组的情况下,基于现有流量来计算网络路径的窄链路带宽和可用带宽的估计。 该网络可以是不同类型的,例如无线战场网络环境或有线或无线商业网络环境。 识别“快速分组”,即在网络中没有经历任何排队延迟的分组。 识别快速分组以将端到端分组延迟解析为其组成组件(确定性,传输和排队延迟),估计路径利用率并消除导致现有技术方法失效的不确定性(假警报)。 估计算法计算沿着网络中的路径行进的快速分组的端到端传输延迟和端到端确定性延迟。 确定性延迟的例子包括卫星传播延迟和时钟效应。 然后,基于快速分组识别算法的结果,跟随两个逻辑分支。 第一个分支计算利用率,第二个分支计算窄链路带宽。 窄链路带宽由分组对色散决定。 可用带宽从窄链路带宽和利用率获得。 估计端到端网络路径的可用带宽允许流量源明智地调节注入网络的应用流量。

    • The solar-based power generator (10) is a system for producing usable electricity from water, which is heated through concentration of ambient, environmental light. The generator (10) includes a reservoir (12) having an open upper end. The reservoir (12) receives a volume of water (14) therein. A convex lens (16) is mounted on an upper edge of the reservoir (12). The convex lens (16) covers the open upper end. A steam output port (11) is in fluid communication with a steam-based electrical generator (18). The convex lens (16) concentrates ambient light on the water (14) stored within the reservoir (16), thus heating the water (14) and converting the liquid water to steam. Additionally, a methane-burning electrical generator (24) is in communication with the reservoir (12). Pollutants in the water (14) produce methane during heating and decomposition, which is burned by the methane-burning electrical generator (24).
