TCP: Transmission Control Protocol in .NET Compose EAN13 in .NET TCP: Transmission Control Protocol

TCP: Transmission Control Protocol using visual .net torender ean13 with asp.net web,windows application ASP.NET Web Application TCP is most frequently r GTIN-13 for .NET un on top of IP in a combination referred to as TCP/IP. This protocol provides error recovery and guaranteed delivery in packet transmission order; it also works with multiple ports so that it can handle more than one application.

TCP is a connection-oriented protocol (page 1142), also known as a stream-based protocol. Once established, a TCP connection looks like a stream of data, not individual IP packets. The connection is assumed to remain up and be uniquely addressable.

Every piece of information you write to the connection always goes to the same destination and arrives in the order it was sent. Because. Types of Networks and How They Work TCP is connection orient GS1-13 for .NET ed and establishes a virtual circuit between two systems, this protocol is not suitable for one-to-many transmissions (see the discussion of UDP, following). TCP has builtin mechanisms for dealing with congestion (or flow) control over busy networks and throttles back (slows the speed of data flow) when it has to retransmit dropped packets.

TCP can also deal with acknowledgments, wide area links, high-delay links, and other situations.. UDP: User Datagram Protocol UDP runs at layer 4 of t ean13 for .NET he IP stack, just as TCP does, but is much simpler. Like TCP, UDP works with multiple ports and multiple applications.

It has checksums for error detection but does not automatically retransmit datagrams (page 1144) that fail the checksum test. UDP is a datagram-oriented protocol: Each datagram must carry its own address and port information. Each router along the way examines each datagram to determine the destination, one hop at a time.

You can broadcast or multicast UDP datagrams to many destinations at the same time by using special addresses.. PPP: Point-to-Point Protocol PPP provides serial line .NET EAN 13 point-to-point connections that support IP. This protocol compresses data to make the most of the limited bandwidth available on serial connections.

PPP, which replaces SLIP5 (Serial Line IP), acts as a point-to-point layer 2/3 transport that many other types of protocols can ride on. It is used mostly for IP-based services and connections, such as TCP or UDP..

Xremote and LBX Two protocols that speed .net framework GTIN-13 up data transfer over serial lines are Xremote and LBX. Xremote compresses the X Window System protocol so that it is more efficient over slower serial lines.

LBX (low-bandwidth X) is based on the Xremote technology and is part of X Window System release X11R6 and higher.. Host Address Each computer interface EAN-13 Supplement 2 for .NET has a unique identifier called a MAC address (page 1158). A system attached to more than one network has multiple interfaces one for each network, each with its own MAC address.

Each packet of information that is broadcast over the network has a destination address. All hosts on the network must process each broadcast packet to see whether it is addressed to that host.6 If the packet is addressed to a given host, that host continues to process it.

If not, the host ignores the packet.. 5. SLIP was one of the f irst serial line implementations of IP and has slightly less overhead than PPP. PPP supports multiple protocols (such as AppleTalk and IPX), whereas SLIP supports only IP.

6. Contrast broadcast packets with unicast packets: Ethernet hardware on a computer filters out unicast packets that are not addressed to that machine; the operating system on that machine never sees these packets..

382 10 Networking and the Internet The network address of a machine is an IP address, which, under IPv4, is represented as one number broken into four segments separated by periods (for example, 192.168.184.

5). Domain names and IP addresses are assigned through a highly distributed system coordinated by ICANN (Internet Corporation for Assigned Names and Numbers www.icann.

org) via many registrars (see www.internic.net).

ICANN is funded by the various domain name registries and registrars and by IP address registries, which supply globally unique identifiers for hosts and services on the Internet. Although you may not deal with any of these agencies directly, your Internet service provider most assuredly does. How a company uses IP addresses is determined by the system or network administrator.

For example, the leftmost two sets of numbers in an IP address might represent a large network (campuswide or companywide); the third set, a subnetwork (perhaps a department or a single floor in a building); and the rightmost number, an individual computer. The operating system uses the address in a different, lower-level form, converting it to its binary equivalent, a series of 1s and 0s. See the following optional section for more information.
