The invention herein described consists of an algorithm, which performs an end-to-end estimation of the bandwidth available in an end-to-end connection established between a server and a client via a packet switching network such as the Internet Protocol Network (IP). This algorithm is used to properly regulate the input rate at the send side. Typical applications are delivering best effort traffic over TCP, or audio and video traffic over RTP / UDP. The invention is particularly effective over wireless Internet and can be used in a content delivery system to dynamically choose the best server between a set of servers to satisfy the request of a client, or to select the best route in a content deliver or global hosting system.

The invention discloses a charge and passenger flow information acquisition method for bus IC (integrated circuit) cards and belongs to the technical field of transportation. After segmental decreasing rate and the effective time duration of accumulative distance are continuously accumulated by a vehicular terminal according to riding distance, charging by distance is completed by swinging at the moment of boarding and alighting, and data related to boarding and alighting of passengers are uploaded to an information center. Data such as boarding flow, alighting flow, OD (origin and destination) flow and interchange flow on specified time scale are acquired first in real time from the information center terminal according to a specific line, a specific area and an additionally designated traffic zone; the data such as the ratio of passengers ranging from average riding distance to different riding distances and the ratio of passengers ranging from average riding time and different riding times on specified time scale are obtained then in non-real time. Real-time acquisition of bus passenger flow information and continuous acquisition of bus riding feature information are achieved by the method while fairness in public resources consumption is improved effectively, and information base for the fair charge and the related decisions for buses are provided.

A system and method that addresses the issue of inducing and exploiting multi-user diversity in, e.g., a WLAN system in a fully distributed and opportunistic manner. In some embodiments, the system includes: an access point having a variable beamformer configured to fluctuate signal strength as perceived by stations within a range of the access point; and a plurality of stations having modified distributed-MAC protocol such as to be channel-aware and opportunistic.
