routing:
Picking some series of links to move a resource from an arbitrary source to an
arbitary target node
P < NP < NPc
Networking Layer:
- IP addresses
- Concerend with routing
-> figuring out which machine you are directly connected to forward a message
to get it 'closer' to the
target
DL Layer:
- MAC address
PHY:
- Modulate medium to physcially repreent information
Trans Layer:
Sockets
1st end-to-end layer
Message goes in...
- Fragment message and manage sending the fragments (packets) |
- Sequence numbering, ECC |
- Relable Delivery(++) |
(a lot of infrastructure) >
TCP
- Reordering of packets |
- Flow Control
|
- Congestion Control |
UDP
- Datagrams (putting everything you want in one go and hope it gets there)
- Connectionless
