摘要： The present invention presents an architecture to dynamically measure and estimate the throughput perceived by a user during a connection in real-time in a wireless network system. The architecture system design of the present invention allows for information gathering independent of the mathematical models used and takes into account security settings in the network hosts. The present invention also sets forth a number of throughput estimators (TEs) that can be used within the architecture to gather the information needed to carry out the throughput estimation calculations. The throughput estimations can then be used for download rate control, QoS, load balancing, etc. The present invention also provides algorithms to calculate the real-time throughput experienced by a user flow.

摘要： As multicast services become prevalent, it is important to find viable solutions for multicasting to mobile nodes. This problem is complicated by the necessity to support multicast services over existing backbone and access networks that may have varying network and/or link layer multicasting capabilities. While most work on supporting multicast services focuses on the IP layer solution, the present invention presents an application-layer approach for providing multicast services to mobile users traversing networks with diverse multicast capabilities. The present invention places multicast proxies in the backbone and access networks to support several multicast-related functions at the application layer including the creation of virtual networks for dynamically tunneling through non-multicast-capable networks.
摘要翻译： 随着组播业务的普及，重要的是为移动节点寻找可行的组播方案。 由于必须通过可能具有变化的网络和/或链路层多播能力的现有骨干网和接入网来支持多播服务，所以这个问题是复杂的。 尽管大多数支持组播服务的工作都集中在IP层解决方案上，但是本发明提出了一种应用层方法，用于向遍历具有不同组播能力的网络的移动用户提供多播服务。 本发明将组播代理放置在骨干网和接入网中，以在应用层支持若干组播相关功能，包括创建虚拟网络，以便通过非多播能力的网络动态隧道化。

摘要： A method of tailoring data streams transmitted to networked user devices is disclosed in which environment information associated with each device is stored at an agent located on those devices. This environment information may include information related to the hardware, interface and application capabilities of the particular device. In another embodiment, this environment information is transmitted and stored at an agent at a local network gateway. And in another embodiment, the environment information is then stored at a mirror agent located in a backbone network of a service provider. By referring to this environment information, a service provider can tailor the transmission of data streams, such as multimedia streams, to a device based on the capabilities of the device and the associated network.
