    • A method, apparatus, and computer program product are provided for making network optimization decisions based on observed network node performance information. Network nodes may continuously report performance measurement information to network servers. Observers may request registration with the and access to the mode measurement information. The observer may specify a measurement threshold that, when met, causes the server to report node measurement data to the observer. The node measurement data enables the observer to make network optimization and control decisions. An optimal radio frequency might be selected; a node might switch between different gateways or cause a handoff from one gateway to another for efficient traffic routing. A user could observe measurement data for friends and receive notice when friends are in close proximity or engaged in like activity such that a social contextual community might be formed.
    • 提供了一种基于观察网络节点性能信息进行网络优化决策的方法,装置和计算机程序产品。 网络节点可以连续向网络服务器报告性能测量信息。 观察者可以请求注册并访问模式测量信息。 观察者可以指定测量阈值,当满足该阈值时,服务器将节点测量数据报告给观察者。 节点测量数据使观察者能够进行网络优化和控制决策。 可以选择最佳射频; 节点可能会在不同的网关之间切换,或者导致从一个网关到另一个网关的切换,以实现高效的流量路由。 用户可以观察朋友的测量数据,并且当朋友接近或参与类似的活动时接收通知,从而形成社会语境社区。

    • The present invention relates to a method and network node for controlling packet flow in a buffer means (13; 14) of a network node of a data network, wherein a nominal capacity is assigned to each data flow, and an additional or free capacity is shifted from a first flow portion to a second flow portion when a new data packet of said second flow portion has been received and said nominal capacity has been exceeded. The nominal capacity may be an upper buffer memory limit used for controlling queuing of data packets in a buffer memory (13) of said buffer means, wherein the memory space of the buffer memory (13) is shared between a plurality of channels allocated to respective packet data connections. Then, the free capacity corresponds to a memory space shifted from a first channel to a second channel, when a new data packet of the second channel has been received and not enough memory space is available for the second channel. Thus, a dynamic buffer-sharing mechanism is provided which reduces the number of packet drops in the buffer memory (13) during congestion and improves network throughput. Alternatively, the nominal capacity may be a nominal flow rate at which data flow traffic is guaranteed in a QoS scheduling algorithm. Then, a residual rate corresponding to the difference between the nominal flow rate and an instantaneous traffic is shifted between flow portions of a buffer means controlled by the scheduling algorithm to maximize total system throughput.
    • 本发明涉及一种用于控制数据网络的网络节点的缓冲器装置(13; 14)中的分组流的方法和网络节点,其中标称容量被分配给每个数据流,并且附加或空闲容量是 当已经接收到所述第二流部分的新数据分组并且已经超过了所述额定容量时,从第一流部分移动到第二流部分。 标称容量可以是用于控制所述缓冲器装置的缓冲存储器(13)中的数据分组排队的高缓冲存储器限制,其中缓冲存储器(13)的存储器空间在分配给相应的多个通道之间共享 分组数据连接。 然后,当接收到第二信道的新数据分组并且没有足够的存储器空间可用于第二信道时,可用容量对应于从第一信道移动到第二信道的存储器空间。 因此,提供了一种动态缓冲器共享机制,其减少了拥塞期间缓冲存储器(13)中的分组丢弃数量,并且提高了网络吞吐量。 或者,标称容量可以是在QoS调度算法中保证数据流业务的标称流量。 然后,与由调度算法控制的缓冲装置的流量部分之间,与标称流量和瞬时流量之间的差值相对应的剩余率在总体系统吞吐量最大化之间移动。
