这是导致拥塞的基本因素,我们将在后面的章节中讨论。 2.2.2 分片格式(Segment Format) TCP是面向字节的协议,意味着发送方向TCP连接写入字节,接收方从TCP连接读取字节。尽管"字节流"描述了TCP提供给应用程序进程的服务,但TCP本身并不通过互联网传输单个字节。相反,源主机上的TCP从发送进程中获取足够的字节来填充一个...
LAN segment A portion of a subnet consisting of a single medium that is bounded by bridges or Layer 2 switches. Subnet One or more LAN segments that are bounded by routers and use the same IP address prefix. Other terms for subnet are network segment and link. Network Two...
As long as a connection is in the TIME_WAIT state, the socket pair cannot be re-used. This is also known as the "2MSL" state. According to RFC793, the value should be two times the maximum segment lifetime on the network. See RFC793 for more information. Note In Microsoft Windows ...
Provide a value to multiply by the maximum segment size (MMS). The acceptable values for this parameter are: an even number from 2 through 64. 展開資料表 Type: UInt32[] Aliases: InitialCongestionWindow Position: Named Default value: None Required: False Accept pipeline input: False Accept ...
The window size used in the actual three-way handshake isn't the window size that's scaled, per RFC 1323 section 2.2:"The Window field in a SYN (for example, a [SYN] or [SYN,ACK]) segment itself is never scaled."It means that the first data packet sent after the three-way ...
Segmente ohne den Bitsatz "Nicht fragmentieren" zu senden, wenn mehrere Neuübertragungen eines Segments nicht bestätigt werden. Wenn das Segment bestätigt wird, wird der MSS verringert, und das Bit "Nicht fragmentieren" wird in zukünftigen Paketen für die Verbindung festgelegt....
IP attaches an IP header to the segment or packet's header, in addition to the information that is added by TCP or UDP. Information in the IP header includes the IP addresses of the sending and receiving hosts, the datagram length, and the datagram sequence order. This information is provi...
Datensegmente gesendet werden, ohne auf eine ACK (unterliegt TCP-Überlastungskontrolle) warten zu müssen. Für typischen Netzwerkverkehr auf Client-Basis wie z. B. Webpages oder E-Mail kann der Web- oder E-Mail-Server dann mehr TCP-Daten schneller an den Clientcomputer senden, was zu ...
The format of the TCP headers attached to the payload follows the below K&R diagram: The header is created in_make_tcp_header_without_checksumin utils, as we cannot compute the checksum without the segment’s payload. There are some fields that are not used in this program (CWR, ECE, RST...
The next three columns show the MSS, Window and irtt that will be applied to TCP connections established via this route. The MSS is the Maximum Segment Size and is the size of the largest datagram the kernel will construct for transmission via this route. The Window is the maximum amount ...
