What is the maximum amount of data a UDP packet can transfer?

65,535 bytes
The field size sets a theoretical limit of 65,535 bytes (8-byte header + 65,527 bytes of data) for a UDP datagram. However the actual limit for the data length, which is imposed by the underlying IPv4 protocol, is 65,507 bytes (65,535 bytes − 8-byte UDP header − 20-byte IP header).

Which transport protocol would be more suitable to implement a request reply protocol UDP or TCP?

UDP is well-suited for “request-reply” semantics beyond RPC; one can use TCP to send a message and get a reply, but there is the additional overhead of setting up and tearing down a connection. DNS uses UDP, largely for this reason.

What is the maximum size of the process data that can be encapsulated in a UDP datagram?

65,507 bytes
The largest amount of process data that can be encapsulated in a UDP datagram is 65,507 bytes. (65,535 minus 8 bytes for the UDP header minus 20 bytes for the IP header). The implementation may impose a smaller limit than this.

Does UDP use MTU?

UDP is the most common standard for VoIP but is limited in capability. The maximum MTU (Maximum Transmission Unit) size of UDP we can receive un-fragmented is 1460 bytes. If your MTU size is larger than 1460 bytes, it can be reduced by removing some of the optional needless information you may transmit to us.

What is TCP header format?

TCP wraps each data packet with a header containing 10 mandatory fields totaling 20 bytes (or octets). Each header holds information about the connection and the current data being sent. TCP data offset – This specifies the size of the TCP header, expressed in 32-bit words. …

In which layer would data be formatted in preparation for transmission?

#3 In which layer would data be formatted in preparation for transmission? Layer 2 — Data Link: Additionally, it’s also the job of the data link layer to present the data in a format suitable for transmission.

Which is better UDP or TCP?

TCP is a connection-oriented protocol, whereas UDP is a connectionless protocol. A key difference between TCP and UDP is speed, as TCP is comparatively slower than UDP. Overall, UDP is a much faster, simpler, and efficient protocol, however, retransmission of lost data packets is only possible with TCP.

What is the maximum and minimum size of the TCP header?

Specifies the size of the TCP header in 32-bit words. The minimum size header is 5 words and the maximum is 15 words thus giving the minimum size of 20 bytes and maximum of 60 bytes, allowing for up to 40 bytes of options in the header.

What is the maximum MTU size UDP?

1460 bytes
The maximum MTU (Maximum Transmission Unit) size of UDP we can receive un-fragmented is 1460 bytes. Most broadband routers are set to an MTU default of 1454 bytes, so its uncommon you can transmit more than our limits.
