CSCI 4550: Chapter 4: Network Layer: Data Plane | SUMMARIES
1. data plane - local, per-router function
- local forwarding
- determines how datagram arriving
on router input port is forwarded to
router out- put port
2. control plane - Network-wide logic
- global routing
- Determines how datagram is
routed among routers along end-
end path from source host to
destination host
3. What's inside a router? - input ports, switching, output ports
- buffer management, scheduling
4. IP: The internet Protocol - datagram format
- addressing
- network address translation
- IPv6
5. two main responsibilities of local forwarding and global routing
the netowork layer
6. sender encapsulates segments into
datagrams, passes to link layer
7. receiver delivers segments to transport layer
proto- col
8. routers - Examines header fields in all IP
data- grams passing through it
- Moves datagrams from input
ports to output ports to transfer
datagrams along end-end path

9. forwarding
, CSCI 4550: Chapter 4: Network Layer: Data Plane | SUMMARIES
move packets from a router's input
link to appropriate router output
link (process of getting through a
single interchange)
10. routing determine route taken by packets
from source to destination, routing
algorithms (process of planning a
trip from source to destination)
11. T or F: network layer T
protocols in EVERY internet
device
running the routing algorithm
12. What generates the local for-
warding table for each
router? 1.) traditional routing algorithms:
imple- mented in routers
13. What are the two control- 2.) software-defined networking
plane approaches? (SDN): implemented in (remote)
servers
14. per-router control plane Individual routing algorithm
components in
each and every router interact in
the con- trol plane(preferred bc it
keeps complexity at networks edge
unlike SDN)
15. software-defined
network- ing(SDN) control 16. Prime service model(example
plane services) for "channel" trans-
porting datagrams from sender
