摘要： The present invention provides a method and apparatus for discovering a path maximum transmission unit. The method comprises receiving a data packet from a first remote device for transmission to a second remote device and determining if a size of the received data packet is greater than a maximum transmission unit (MTU) value. In response to determining that the size of the received data packet is greater than the MTU value, the method further comprises transmitting a portion of the received data packet to the second remote device and transmitting a message to the first remote device indicating that the size of the received data packet exceeds the MTU value.

摘要： A method, system and apparatus for maintaining a two-byte identification field of IP headers when a Gigabit Ethernet is in use are provided. Since the IP identification field is of two bytes, there is a limited number of identification numbers that may be used. Due to the high data transfer rate of the Gigabit Ethernet, this number may be reached within one second. Hence, there may be a possibility that two or more packets may have the same identification number while in transit. In a representative embodiment, one identification number is used for packets that may not be fragmented; thus, freeing the rest of the numbers for packets that may be fragmented.

摘要： A method, system, and product are described for alleviating router congestion when the router is processing packets transmitted by computer systems having a congestion notification capability. The router marks packets transmitted between a first computer system and a second computer system when the first and second computer systems have the congestion notification capability. The marking indicates that the router is moderately congested. A marked packet is then received by the first computer system. The router then drops packets transmitted by the first computer system when the packets were transmitted subsequent to the receipt of the marked packet.

摘要： A method, apparatus, and computer instructions for reactivating an existing connection to a remote data processing system. A data packet is created using a previously acknowledged sequence number for the connection. The sequence number is used to uniquely number data bytes sent in a connection, such as a TCP connection. With this sequence number, devices and components, such as routers and fire walls will forward the packet to the destination. A special data sequence, such as a MAC address of the remote data processing system repeated a selected number of times, is placed in the data packet. This special data sequence causes the remote data processing system to wake up from a sleep mode when received by the remote data processing system. The data packet is sent to the remote data processing system using the existing connection. The use of a subnet directed broadcast is avoided. Thus, problems associated with routing wake up packets are avoided.
摘要翻译：一种用于重新激活与远程数据处理系统的现有连接的方法，装置和计算机指令。使用先前确认的连接序列号创建数据包。序列号用于唯一地编号连接中发送的数据字节，例如TCP连接。使用此序列号，设备和组件（如路由器和防火墙）将将数据包转发到目的地。特殊数据序列，例如重复所选次数的远程数据处理系统的MAC地址，被放置在数据包中。该特殊数据序列使得远程数据处理系统在由远程数据处理系统接收时从睡眠模式唤醒。使用现有连接将数据包发送到远程数据处理系统。避免使用子网定向广播。因此，避免与路由唤醒分组相关的问题。

摘要： A method, system and apparatus for reducing dataflow disruption when increases in path maximum transmission unit (PMTU) are being detected are provided. Conventionally, when increases in PMTU are being detected, an increased-in-size data packet is sent by a transmitting host. If an intermediate link is unable to process the data packet through, it drops the data packet and sends an error message to the transmitting host. The transmitting host has to reduce the size of the data packet and resend it. The procedure outlines in this disclosure obviates the need to resend the data packet. It does so by transmitting an old data packet that has been increased in size. Hence, there is no need to resend the data packet if it is dropped.
摘要翻译：提供了在检测到路径最大传输单元（PMTU）的增加时减少数据流中断的方法，系统和装置。通常，当检测到PMTU的增加时，发送主机发送大小的数据分组。如果中间链路无法处理数据包，则会丢弃数据包，并向发送主机发送错误消息。发送主机必须减少数据包的大小并重新发送。本公开的过程概述避免了重新发送数据分组的需要。它通过发送已经增加的旧数据分组来实现。因此，如果丢弃数据包，则不需要重新发送。
