Path MTU Discovery (PMTUD) is a standardized technique in computer networking for determining the maximum transmission unit (MTU) size on the network path between two Internet Protocol (IP) hosts, usually with the goal of avoiding IP fragmentation. PMTUD was originally intended for routers in Internet Protocol Version 4 (IPv4). [1]
MTU is sometimes used to describe the maximum PDU sizes in communication layers other than the network layer. Cisco Systems and MikroTik use L2 MTU for the maximum frame size. [18] [19] Dell/Force10 use MTU for the maximum frame size. [20] Hewlett-Packard used just MTU for the maximum frame size including the optional IEEE 802.1Q tag. [21]
Version 5.6 of the AutoPatcher engine included a new user interface, and more "intelligent" [7] scripting than the previous version, 5.1. Changes from version 5.1 include: Support for Windows Vista and Windows XP Media Center Edition; New detections: Windows Media Player, Windows Live Messenger/MSN Messenger, DirectX, .NET and Windows Installer;
TCP window scale option is needed for efficient transfer of data when the bandwidth-delay product (BDP) is greater than 64 KB [1].For instance, if a T1 transmission line of 1.5 Mbit/s was used over a satellite link with a 513 millisecond round-trip time (RTT), the bandwidth-delay product is ,, =, bits or about 96,187 bytes.
The first, Windows XP 64-Bit Edition, was intended for IA-64 systems; as IA-64 usage declined on workstations in favor of AMD's x86-64 architecture, the Itanium edition was discontinued in January 2005. [57] A new 64-bit edition supporting the x86-64 architecture, called Windows XP Professional x64 Edition, was released in April 2005. [58]
The default TCP Maximum Segment Size is for IPv4 is 536. For IPv6 it is 1220. [1]: §3.7.1 Where a host wishes to set the maximum segment size to a value other than the default, the maximum segment size is specified as a TCP option, initially in the TCP SYN packet during the TCP handshake. The value cannot be changed after the connection is ...
The IEEE 802.3 Ethernet standard originally mandated support for 1500-byte MTU frames, 1518 byte total frame size (1522 byte with the optional IEEE 802.1Q VLAN/QoS tag). The IEEE 802.3as update grandfathered in multiple common headers, trailers, and encapsulations by creating the concept of an envelope where up to 482 bytes of header and ...
Imagine a Wi-Fi base station having a speed of 20 Mbit/s and an average packet size of 750 byte. How large should the IP queue be? A voice over IP client should be able to transmit a packet every 20 ms. The estimated maximum number of packets in transit would then be: Estimated buffer size = 20000000 * 0,020 / 8 / 750 = 66
