    • A server may be bypassed in the context of retransmitting data packets, when such data packets are missing or lost due to interference or some other network error. Decreased throughput and other disadvantages associated with data packet retransmission are avoided by negating the need to transmit retransmission request packets to the server and retransmitting a missing/lost data packet from the server. Instead, retransmission request packets may be sent to a router, and the router may respond by directly retransmitting the missing/lost data packet to the client, where prior to retransmitting the missing/lost data packet, it is determined whether the data packet is a Transport Control Protocol or User Datagram Protocol packet, and proceeding with the retransmitting only if the data packets is a Transport Control Protocol packet.
    • 当这种数据包由于干扰或某些其他网络错误而丢失或丢失时,可能会在重发数据包的上下文中绕过服务器。 通过否定向服务器发送重传请求分组的需要并从服务器重传丢失/丢失的数据分组来避免与数据分组重传相关联的吞吐量和其他缺点的降低。 相反,重传请求分组可以被发送到路由器,并且路由器可以通过直接重传丢失/丢失的数据分组给客户机来进行响应,其中在重传丢失/丢失的数据分组之前,确定数据分组是否是 传输控制协议或用户数据报协议分组,并且仅当数据分组是传输控制协议分组时才进行重传。

    • An improved reel driving apparatus for a magnetic recording and reproducing apparatus which is capable of simplifying the construction of a reel mechanism which requires different rotation torques of normal and reverse rotation directions. The apparatus includes a reversible motor, a transmission gear which is inserted onto a shaft between a supply reel and a take-up reel and is rotatable by a rotational force from the reversible motor, a slip mechanism having an input gear drivingly connected with the transmission gear and an output gear having a pair of gear portions, with the input gear receiving the rotational force from the input gear through a friction member, a lifting and lowering gear having a pair of gear portions, which are selectively connected with the gear portions of the output gear by a lifting and lowering member, and being rotated, lifted, and lowered with respect to the shaft, and an idler gear which is always connected with the lifting and lowering gear for selectively transferring a rotational force from the lifting and lowering gear to one of supply and take-up reels.
