    摘要： A method and system are provided for controlling a volume of incoming traffic into a network having a plurality of ingress routers. The method includes monitoring respective loads of the plurality of ingress routers. The method further includes selecting a particular one of the plurality of ingress routers to receive future incoming traffic based on at least the respective loads of the plurality of ingress routers. The method also includes creating a mapping between an internal source IP address and a client IP address. The internal source IP address relates to the particular one of the plurality of routers. The client IP address is for a client device accessing the Internet through the network. The method additionally includes rewriting a destination IP address of the incoming traffic based on the mapping. At least the monitoring, selecting, and creating steps are performed by a controller.

    摘要： A snoop receiver, method and computer program product for increasing the efficiency of TCP protocol operations at the snoop receiver by assuming there is no reordering over the wireless hop. The method performs maintaining a copy of each packet received, the copy adapted for retransmission to the receiver device on behalf of the source device and maintaining for each packet received, a virtual send time (VST) value of that packet. The VST corresponds to a virtual time the packet was sent or retransmitted to the receiver device. There is further maintained an estimate of the receiver device's time (VRT) based on acknowledgement (ACK) messages for packets received from the receiver device. Responsive to receiving an acknowledgement for a packet sent at the time VST, the method infers any lost packets and retransmits a copy of any lost packets having a VST value sent before the receiver's VRT estimate.

    摘要翻译： 一种窥探接收机，方法和计算机程序产品，用于通过假设无线跳点没有重新排序来提高窥探接收机的TCP协议操作的效率。 该方法执行维护接收到的每个分组的副本，适于代表源设备重新发送给接收机设备的复本，并维护接收到的每个分组的该分组的虚拟发送时间（VST）值。 VST对应于分组被发送或重传到接收机设备的虚拟时间。 基于从接收机设备接收的分组的确认（ACK）消息，还进一步保持对接收机设备的时间（VRT）的估计。 响应于接收对在时间VST发送的分组的确认，该方法推断任何丢失的分组，并重传在接收机的VRT估计之前发送的具有VST值的丢失分组的副本。
