Question

if a 2000 bytes data message is sent using TFTP corresponding ethernet packet will be how many bytes

Answer 1

Answer:

If a 2000 bytes data message is sent using TFTP then corresponding Ethernet packet will be of 2050 bytes.

Explanation:

TFTP is an incredibly straightforward protocol to transfer files.  

Any exchange starts with a solicitation to read or write a file. In the event that the server allows the solicitation, the connection is opened and the file is sent in blocks of 512 bytes (fixed length). Blocks of the file are numbered consecutively, beginning at 1. Every data packet must be recognized by an affirmation packet before the following one can be sent. End of the exchange is accepted on a data packet of under 512 bytes.  

Practically all blunders will cause end of the connection (absence of unwavering quality). In the event that a packet loses all sense of direction in the network, a break will happen, after which a retransmission of the last pakcet (data or affirmation) will occur.  

The initial 2 bytes op the TFTP message structure an opcode. For a read request (RRQ) and a write request (WRQ) the filename indicates the record on the server that the client needs to peruse from or write to. The filename-string is ended by a zero-byte. The mode is one of the strings netascii or octet, ended by a zero-byte.  

• netascii implies that the data are lines of ascii-content with each line ended by CR-LF;  

• An octet data transmit regards the data as 8-bit bytes with no explanation.  

Every data packet contains a block number that is later utilized in an affirmation packet.
