Abstract: A TCP/IP packet decoder fetches, from a packet received via a satellite communication system, IP version information, which is provided to version comparators. When a version comparator indicates a match, protocol information is provided to a TCP comparator. If the TCP comparator determines that the packet is a TCP data packet, a flag is raised causing generation of a TCP acknowledgment for transmission to a source device. In another embodiment, a layer 3 switch or router includes a TCP hardware filter to determine whether the received packet is a TCP data packet, thereby causing the TCP data packet to be mirrored for transmission to a modem. In a third embodiment, a TCP hardware filter, provides an indication to a layer 2 switch when a TCP data packet is received causing the TCP data packet to be mirrored for transmission to a modem, which generates and transmits a TCP acknowledgment.

Abstract translation: TCP / IP分组解码器从经由卫星通信系统接收到的分组中获取提供给版本比较器的IP版本信息。 当版本比较器指示匹配时，将协议信息提供给TCP比较器。 如果TCP比较器确定分组是TCP数据分组，则引发标志，从而产生用于传输到源设备的TCP确认。 在另一个实施例中，层3交换机或路由器包括TCP硬件过滤器，以确定接收的分组是否是TCP数据分组，从而使TCP数据分组被镜像以传输到调制解调器。 在第三实施例中，TCP硬件过滤器在接收到TCP数据分组时向第二层交换机提供指示，导致TCP数据分组被镜像以传输到生成并发送TCP确认的调制解调器。
