Data Link Frame
-
-
-
-
Data - Contains the frame
payload (i.e., packet header segment header, and the data).
LAN Topologies
-
-
Bus - Used in legacy networks. All end
systems are chained to each other and terminated in some form on each end.
Switches are not required to interconnect the end devices. Bus topologies using coax cables
were used in legacy Ethernet networks because it was inexpensive and easy to set
up.
Ring - End systems are connected to their
respective neighbor forming a ring. Unlike the
bus topology, the ring does not need to be
terminated. Ring topologies were used in egacy Fiber Distributed Data Interface (FDDI)
and Token Ring networks.
WAN Topologies
-
Hub and Spoke
- A central site interconnect branch sites using point to points links.
Mesh
- Provides high availability, but
requires that every end system be interconnected to every other
system Administrative and physical
costs can be significant.
-
-
- The purpose and function of the data link layer in preparing communication for transmission on specific media
PURPOSE
FUNCTION
- provides methods for exchanging data frames between devices over a common media
