text-oriented communications facility between Telnet server and client using a virtual terminal connection. It uses
the TCP protocol.
TFTP
TFTP (Trivial File Transfer Protocol) is a file transfer protocol notable for its simplicity. It is generally used for
automated transfer of configuration or boot files between machines in a local environment. Different from FTP, It
has been implemented on top of the User Datagram Protocol (UDP) using port number 69 and thus can penetrate
multiple firewalls. Compared to FTP, TFTP is extremely limited, providing no user authentication, and is rarely
used interactively by a user due to unreliability. Yet, it is suitable for transferring trivial files on private networks.
ToS
The modern redefinition of the TOS field is a six-bit Differentiated Services Field (DS field) field and a two-bit
Explicit Congestion Notification (ECN) field. While Differentiated Services is somewhat backward compatible
with TOS, ECN is not. The TOS field could specify a datagram's priority and request a route for low-delay,
high-throughput, or highly-reliable service.
UDP
The User Datagram Protocol (UDP) is one of the core members of the Internet protocol suite, the set of network
protocols used for the Internet. With UDP, computer applications can send messages, in this case referred to as
datagrams, to other hosts on an Internet Protocol (IP) network without requiring prior communications to set up
special transmission channels or data paths.
VLAN
A virtual local area network, virtual LAN or VLAN, is a group of hosts with a common set of requirements, which
communicate as if they were attached to the same broadcast domain, regardless of their physical location.
VLAN ID
VLAN Identifier (VID): a 12-byte field specifying the VLAN to which the frame belongs.
