Internet protocol suite - Open Encyclopedia By convention certain well known ports are associated with specific applications. Applications most commonly run on TCP or UDP, and are often associated with a well-known port number. The internet protocol suite can be described by analogy with the OSI model, which describes the layers of a protocol stack, not all of which correspond well with internet practice. open-encyclopedia.com /TCP/IP   (1555 words)

Port (computing) - Wikipedia, the free encyclopedia These software network ports may also connect internal programs on a single computer system. In computing, a port (derived from seaport) is a connection through which data is sent and received. A hardware port is an electrically wired outlet on a piece of equipment into which a plug or cable connects. en.wikipedia.org /wiki/Computer_port   (517 words)

well-known port numbers - a Whatis.com definition - see also: TCP port numbers, contact port numbers, service contact port numbers The IANA list of port numbers, including the well-known port numbers, is still apparently the most complete list. The well-known port numbers are also listed as part of the IETF's Request for Comments (RFC) 1700, "Assigned Numbers." The well-known port numbers are the port numbers that are reserved for assignment by the Internet Corporation for Assigned Names and Numbers (ICANN) for use by the application end points that communicate using the Internet's Transmission Control Protocol (TCP) or the User Datagram Protocol (UDP). whatis.techtarget.com /definition/0,,sid9_gci514078,00.html   (336 words)

Message-Oriented Middleware and the Software Engineer Of course, there are 'accidental' issues with respect to scalability as well: the design of HTTP forces the server to close its half of the connection first, leaving each TCP connection in a TIME_WAIT state for up to four minutes after a few milliseconds of use. UDP, also known as 'Unreliable Datagram Protocol,' is a thin wrapper around raw IP service. It is well suited for three scenarios: broadcasting or anycasting on a LAN, lossy isochronous media, and very large client/server ratios. www.4k-associates.com /4K-Associates/moma.html   (4862 words)

List of FPGA-based Computing Machines Welcome to the list of FPGA-based computing machines. This list was first compiled in the beginning of 1994, where there were a small handful of FPGA boards available. The Computer consists of a regular 3D array of very coarse grain application-specific FPGA called the Field-Programmable Operator Array (FPOA).The FPOA granularity is at the 8/16 bit operator level instead of at the gate level. www.io.com /~guccione/HW_list.html   (9194 words)

List of well-known ports (computing) - Wikipedia, the free encyclopedia Sometimes ports may be used for different applications or protocols than their official IANA designation.

Glossary of Internet Terms Well Known Ports The Well Known Ports are assigned by the IANA and on most systems can only be used by system (or root) processes or by programs executed by privileged users. Ports are used in the TCP [RFC793] to name the ends of logical connections which carry long term conversations.

Encyclopedia: HTTP In computing, a port (derived from seaport) is usually a connection through which data is sent and received. In computing, Secure shell or SSH is both a computer program and an associated network protocol designed for logging into and executing commands on a networked computer. In computing, hypertext is a user interface paradigm for displaying documents which, according to an early definition (Nelson 1970), branch or perform on request. www.nationmaster.com /encyclopedia/HTTP   (2355 words)

TCP/IP Ports Tim Williams' list of Ports Used by Computer Games has lots of good info. We further recommend that SMTP authentication be implemented on the standard Mail Submission Port, port 587, and that ISPs encourage their customers to switch their mail client software (for example, MS Outlook, Eudora, and so on) to this port. This port is commonly used by HP OpenView Storage Data Protector (formerly HP OmniBack). www.chebucto.ns.ca /~rakerman/port-table.html#Related   (3069 words)

Process Cloning in C LG #51 It is one of many so-called well-known ports defined in /etc/services.) There came to be so many daemon processes waiting for connections that the amount of available swap space and the number of user processes became limited. Mobile computing is often used to mean email access from a laptop, process migration refers to the automatic redistribution of active processes within a cluster system, and agent migration describes processes on a mission, gathering data for a full report upon returning home. The first example is an extension of the client-server paradigm of the 1980s while the other examples, self-directed movement of a process from one networked machine to another, is the subject of leading edge research [1]. sunsite.utk.edu /LDP/LDP/LG/issue51/vrenios.html   (1098 words)

Webopedia: Well-Known TCP Port Numbers Some ports have numbers that are preassigned to them by the IANA, and these are known as well-known ports (specified in RFC 1700). Port numbers range from 0 to 65536, but only ports numbers 0 to 1024 are reserved for privileged services and designated as well-known ports.

TCP, Transmission Control Protocol This is computed as the 16-bit one's complement of the one's complement sum of a pseudo header of information from the IP header, the TCP header, and the data, padded as needed with zero bytes at the end to make a multiple of two bytes. The number of data bytes beginning with the one indicated in the acknowledgment field which the sender of this segment is willing to accept. Each endpoint is defined by an IP address and a TCP port number and is implemented as a finite state machine. www.networksorcery.com /enp/protocol/tcp.htm   (2232 words)

These addresses are matched in the SMC 7004ABR setup with trigger port configuration of TCP and public port of 6969,6881-6999 with public type of TCP and enabled. www.knoppix.net /forum/viewtopic.php?t=21284   (2993 words)

Increasing Security on IP Networks Access lists can be used to deny connections that are known to be a security risk and then permit all other connections, or to permit those connections that are considered acceptable and deny all the rest. In most cases, input access lists and output access lists accomplish the same functionality; however, input access lists are more intuitive to some people and can be used to prevent some types of IP address "spoofing" where output access lists will not provide sufficient security. You can also specify a list of IP addresses that are allowed to send messages to the router by using the access-list option of the snmp-server community command. www.cisco.com /univercd/cc/td/doc/cisintwk/ics/cs003.htm#13241   (6875 words)

draft-ietf-idwg-idmef-xml-12.txt A list of acceptable meaning keywords is not within the scope of the document, although later versions may undertake to establish such a list. NOTE: It should be noted that different types of analyzers may compute confidence values in different ways and that in many cases, confidence values from different analyzers should not be compared (for example, if the analyzers use different methods of computing or representing confidence, or are of different types or configurations). Care should be taken when implementing systems that process confidence values (such as event correlators) not to make comparisons or assumptions that cannot be supported by the system's knowledge of the environment in which it is working. xml.coverpages.org /draft-ietf-idwg-idmef-xml-12.txt   (9740 words)

A Brief History of the Net The connections to the individual computers had to be customized for each machine at the time, but the standard protocol is what became the Internet Protocol (IP) that we still use an augmented form of today. The driving force behind the creation of a nationwide network has been attributed to things as trivial as a man wanting to be able to have a single computer terminal on his desk rather than three [HL1996], to the ability to have a computer network that could survive a war. Part of the community of military users on the 'net in the 1980's were at first reluctant to believe that their computer were being broken into, and later were reluctant to believe that any of the machines that could be accessed had any information of use. www.cs.umd.edu /~egolub/abhotn.shtml   (5472 words)

HyperText Transfer Protocol - Wikipedia, the free encyclopedia An HTTP client, such as a web browser, typically initiates a request by establishing a TCP connection to a particular port on a remote host (port 80 by default; see List of well-known ports (computing)). Development of HTTP was co-ordinated by the World Wide Web Consortium and working groups of the Internet Engineering Task Force, culminating in the publication of a series of RFCs, most notably RFC 2616, which defines HTTP/1.1, the version of HTTP in common use today. HTTP defines eight methods indicating the desired action to be performed on the identified resource. en.wikipedia.org /wiki/HTTP   (1144 words)

Apple Macintosh - Wikipedia, the free encyclopedia Apple has also contributed heavily to the field of mobile computing, and many features of their mobile computers have become the norm. The PowerBook 100, 140, and 170 set the ergonomic standard for the placement of the keyboard in 1991 by moving the keyboard behind a palm rest, rather than right at the bottom of the laptop. Macintoshes include two standard data transfer ports: USB, standardized in 1998 with the iMac; and FireWire, a less popular standard developed by Apple to support higher-performance devices. en.wikipedia.org /wiki/Apple_Macintosh   (7063 words)
