# b01fd836_Transport_Layer_clarification
|
|
|
|
The Transport Layer is a _logical_ representation of the connection between two
|
|
hosts on the Internet. It does not include the entire path (through various
|
|
routers) from source to destination. This detail is assumed and is the concern
|
|
of the Internet Layer - the next layer down.
|
|
|
|
When applications communicate accross via TCP they "perceive" a simple direct
|
|
connection however this abstracts the fact that the data may:
|
|
|
|
- be split into dozens of packets
|
|
- travel through different physical pathways and different routers
|
|
- face congestion, packet loss and network failure.
