    • A method for more efficiently operating a network, and more particularly, for discovery of a path maximum transmission unit (PMTU) between nodes on an IP network, is provided. The method includes (a) comparing the size of a received packet with a maximum transmission unit (MTU) of a next link; and (b) if the size of the received packet is greater than the MTU of the next link, generating an error message, transmitting the generated error message to a source node, generating a test message of the size of the MTU of the next link, and transmitting the generated test message to a destination node. According to the PMTU discovery method, a PMTU can be determined in a shorter time, and it is possible to minimize the use of network resources.
    • 提供了一种用于更有效地操作网络的方法,更具体地,用于发现IP网络上的节点之间的路径最大传输单元(PMTU)。 该方法包括:(a)将接收到的分组的大小与下一个链路的最大传输单元(MTU)进行比较; 和(b)如果所接收的分组的大小大于下一个链路的MTU,则生成错误消息,将生成的错误消息发送到源节点,生成下一个链路的MTU大小的测试消息 ,并将生成的测试消息发送到目的地节点。 根据PMTU发现方法,可以在更短的时间内确定PMTU,并且可以最小化网络资源的使用。

    • A method and apparatus for processing a plurality of data in a protocol module. The method includes (a) determining priorities of the plurality of data based on information on the plurality of data, and (b) driving a plurality of protocol modules, which process the plurality of data according to a predetermined protocol, based on the priorities determined in (a). Accordingly, it is possible to process the plurality of data at a high rate by constructing a plurality of Internet protocol (IP) layers and a plurality of a transmission control protocol/user datagram protocol (TCP/UDP) layers in a hardware manner without involvement of a processor.
    • 一种在协议模块中处理多个数据的方法和装置。 该方法包括:(a)基于关于多个数据的信息来确定多个数据的优先级,以及(b)基于确定的优先级来驱动多个协议模块,其根据预定协议处理多个数据 在一个)。 因此,可以通过以硬件方式构造多个因特网协议(IP)层和多个传输控制协议/用户数据报协议(TCP / UDP)层而以高速率来处理多个数据,而不涉及 的处理器。
