why udp is used over tcp?
39343
Since UDP doesn't have many requirements, it offers a faster connection. TCP, on the other hand, is slower but more reliable. If you need speed more than reliability, you should use UDP instead of TCP. TCP has provisions for data packet sequencing, acknowledgements, error detection, and correction.

TCP is a connection-oriented protocol, whereas UDP is a connectionless protocol. The speed for TCP is slower while the speed of UDP is faster. ... TCP does error checking and also makes error recovery, on the other hand, UDP performs error checking, but it discards erroneous packets.

Both UDP and TCP Port 135 are required for communication between domain controllers and clients to domain controllers. TCP Port 139 and UDP 138 network ports are used by the SYSVOL replication service to replicate contents of SYSVOL folder.

UDP is also a transport-layer protocol and is an alternative to TCP. It provides an unreliable datagram connection between applications. ... In terms of the OSI model, IP is a network-layer protocol. It provides a datagram service between applications, supporting both TCP and UDP.

FTP uses two TCP connections for communication. One to pass control information, and is not used to send files on port 21, only control information. And the other, a data connection on port 20 to send the data files between the client and the server.

HTTP is an application layer protocol, which could be encapsulated with a protocol that uses UDP, providing arguably faster reliable communication than TCP.

Yes, you can use the same port number for both TCP and UDP. ... Technically the port pools for each protocol are completely independent, but for higher level protocols that can use either TCP or UDP it's convention that they default to the same port number.

The connection-oriented methods of TCP make security much easier to implement in that protocol in UDP. However, there are encryption standards available for UDP. The main option that directly aims at security UDP is the Datagram Transport Layer Security protocol or DTLS.

TCP is connection oriented – once a connection is established, data can be sent bidirectional. UDP is a simpler, connectionless Internet protocol. Multiple messages are sent as packets in chunks using UDP.

['1) UDP is much faster. TCP is slow as it requires 3-way handshake. ... ', '2) DNS requests are generally very small and fit well within UDP segments.', '2) UDP is not reliable, but reliability can added on application layer. An application can use UDP and can be reliable by using a timeout and resend at the application layer.']

Faster Speed – UDP VPN service offers significantly greater speeds than TCP. ... Preferred – UDP VPN tunnels are the preferred OpenVPN connection method if your network supports it. Lower Reliability – On rare occasions UDP can be less reliable that TCP VPN connections as UDP does not guarantee the delivery of packets.

TCP port 1600 uses the Transmission Control Protocol. TCP is one of the main protocols in TCP/IP networks. TCP is a connection-oriented protocol, it requires handshaking to set up end-to-end communications. ... Guaranteed communication over TCP port 1600 is the main difference between TCP and UDP.

- UDP packets are a more widely used protocol. - TCP packets are smaller and thus more efficient to use. - TCP packets are connection oriented, whereas UPD packets are connectionless. - UDP is considered to be more reliable because it performs error checking.

UDP: Typically, ISAKMP uses UDP as its transport protocol. ISAKMP traffic normally goes over UDP port 500, unless NAT-T is used in which case UDP port 4500 is used.

Because web servers operate on TCP port 80, both of these sockets are TCP sockets, whereas if you were connecting to a server operating on a UDP port, both the server and client sockets would be UDP sockets.

That's where protocols such as the Transmission Control Protocol (TCP) come in. TCP is used in conjunction with IP in order to maintain a connection between the sender and the target and to ensure packet order. For example, when an email is sent over TCP, a connection is established and a 3-way handshake is made.

TCP is a connection-oriented protocol, whereas UDP is a connectionless protocol. The speed for TCP is slower while the speed of UDP is faster. TCP uses handshake protocol like SYN, SYN-ACK, ACK while UDP uses no handshake protocols.
