    • Mapping data packets of a first data stream into data fields of a second data stream at several transmitters is provided by generating a first data stream with first data packets containing data associated with stationary receivers and second data packets containing data associated with mobile receivers in a head-end, where second data packets at the start of a group of consecutively transmitted second data packets contain placeholders into which signaling information is filled. A first data stream is transmitted from the head-end to each transmitter. Each transmitter extracts signaling information from the second data packets indicating in which data slot and in which data sub-frame of a received data frame the second data packet is transferred. Each transmitter inserts synchronization data in a specific data packet in each data slot containing second data packets. The first and second data packets are mapped consecutively into the second data stream.
    • 通过产生具有第一数据分组的第一数据分组来提供第一数据流的数据分组到多个发射机的第二数据流的数据字段,第一数据分组包含与固定接收机相关联的数据和包含与头部中的移动接收机相关联的数据的第二数据分组 -end,其中在一组连续发送的第二数据分组的开始处的第二数据分组包含填充信令信息的占位符。 第一数据流从头端发送到每个发射机。 每个发射机从第二数据分组中提取信令信息,指示在哪个数据时隙中和在哪个数据子帧中接收数据帧的第二数据分组被传送。 每个发射机在包含第二数据分组的每个数据时隙中的特定数据分组中插入同步数据。 第一和第二数据包被连续地映射到第二数据流中。

    • In accordance with the present invention, a system, method, and computer-readable medium for identifying malware at a network transit point such as a computer that serves as a gateway to an internal or private network is provided. A network transmission is scanned for malware at a network transit point without introducing additional latency to the transmission of data over the network. In accordance with one aspect of the present invention, a computer-implemented method for identifying malware at a network transit point is provided. More specifically, when a packet in a transmission is received at the network transit point, the packet is immediately forwarded to the target computer. Simultaneously, the packet and other data in the transmission are scanned for malware by an antivirus engine. If malware is identified in the transmission, the target computer is notified that the transmission contains malware.
    • 根据本发明,提供了一种系统,方法和计算机可读介质,用于在诸如用作内部或专用网络的网关的计算机之类的网络转接点处识别恶意软件。 在网络传输点扫描网络传输恶意软件,而不会对网络上的数据传输造成额外的延迟。 根据本发明的一个方面,提供了一种用于在网络中转点识别恶意软件的计算机实现的方法。 更具体地,当在网络转接点接收到传输中的分组时,该分组立即被转发到目标计算机。 同时,传输中的数据包和其他数据由防病毒引擎扫描恶意软件。 如果在传输中识别到恶意软件,则通知目标计算机该传输包含恶意软件。
