Presentation layer – responsible for data structures
used by networked applications.
Application layer - networked software applications
such as e-mail, Telnet, and ftp.
Logical grouping of information that includes a
header containing control information and (usually)
user data. Packets refer to network layer units of
data, with messages divided into several packets.
Some networks use fixed packet sizes; others use
variable packet sizes.
standard header information that identifies the
packet.
In contrast, frames contain only data;
information about the frames transmits on the
control plane.
The terms datagram, frame, message, and segment
describe logical information groupings at various
layers of the OSI reference model and in various
technology circles.
Point-to-Point Protocol. a successor to SLIP that
provides
router-to-router
connections over synchronous and asynchronous
circuits.
RIP feature to sets routes learned on the same port
as the transmitted RIP message an infinite distance.
Prevents the propagation of routes from crashed
routers through the network.
Permanent Virtual Circuit.
associated with circuit establishment and tear down
in situations where certain virtual circuits must exist
all the time.
Routing Information Protocol. Internet protocol used
to exchange routing information within a system.
RIP uses hop count as a routing metric.
Network layer device that uses one or more metrics
to determine the optimal path to forward network
traffic. Routers forward packets from one network to
another based on network layer information.
router may connect networks using various protocols
by encapsulating data within another network's
packet format or by removing layers of packet
formatting.
Simple Network Management Protocol.
management protocol used in TCP/IP networks.
SNMP provides a way to monitor and control
network devices, and to manage configurations,
Statistics collection, performance, and security.
address used for the subnet address.
