TFTP
The TFTP protocol (

rotocol) is a very simple file
transfer protocol. TFTP supports merely the reading or writing of files. Many
functions of the more powerful FTP (

P
rotocol), such as rights
allocation using chmod, displaying existing files or user authentication, are
not available. Unlike FTP, which requires a connection-oriented transport
protocol, TFTP is normally operated via a connectionless protocol like UDP.
TOS
The ToS field (
T

S
ervice field) is a data field in the IP header, in which
the services of the datagram are defined. With the ToS information,
computers can specify network-relevant types of service. Here, various
parameters, such as the bandwidth, the transfer speed or the reliability of
the transfer can be defined. Furthermore, the priority handling of
datagrams, the type of throughput and the reservation of resources in the
routers can be defined.
Trace
A trace is a sequence of instructions, which begins with any start point and
in which the program branches and their path selection are defined. It
allows the program flow to be traced step by step. A trace is primarily used
in troubleshooting and debugging.
U
UDP
Unlike the connection-oriented TCP (

P
rotocol is a minimal, connectionless network protocol that
belongs to the transport layer of the Internet protocol family. The task of
UDP is to send data transferred over the Internet to the correct application.
With UDP, a protocol was required that was responsible only for the
addressing without securing the data transfer, since this would result in
delays in the voice transmission.
