摘要： A first communication device receives an ATM cell bound for a second ATM device from a first ATM device via an ATM interface, and then the first communication device sends a data frame including the ATM cell to the second ATM device via wide area Ethernet. In addition, the first communication device sends a synchronization frame to the second ATM device via the wide area Ethernet continuously at a predetermined time interval in accordance with a clock frequency of the first ATM device. A second communication device receives the synchronization frame and measures a clock frequency of the first ATM device in accordance with a time interval of receiving the synchronization frame so as to reproduce a clock having the same frequency as the measured clock frequency. After that, the second communication device sends the clock to the second ATM device via an ATM interface.

摘要： A communication method is provided in which irrespective of whether the communication apparatus is in a condition of being able to cache the received data or not, it is made possible to receive segment data having a sequence number assigned thereto continuously with the reception of the resent lost data, whereby the reduction in communication throughput can be reduced and the time can be reduced that is required for the reception of all the segment data to be completed. In a first communication apparatus and a second communication apparatus that perform data communication based on the TCP, the first communication apparatus receives information corresponding to a scheduled sequence number equal to the previously received scheduled sequence number (S205: YES), and when the number of times of continuous reception reaches a predetermined number of times (S208: YES), returns the sequence number to the received scheduled sequence number (S209).
摘要翻译：提供了一种通信方法，其中无论通信装置是否处于能够缓存所接收的数据的条件，可以接收分配给它的序列号的片段数据，随后接收到丢失的信息数据，从而可以减少通信吞吐量的降低，并且可以减少接收完成所有分段数据所需的时间。在执行基于TCP的数据通信的第一通信装置和第二通信装置中，第一通信装置接收与先前接收到的调度序列号相等的调度序列号的信息（S 205：是），当数字的连续接收次数达到预定次数（S 208：是），将序列号返回到接收到的调度序列号（S109）。
