W2L1 - Packet Switching and Queue Flashcards
1
Q
Full Mesh Network
A
Expensive to run a link between all nodes
Very failure resistant
2
Q
Ring Network
A
Cheaper
Not failure resistant
3
Q
Switched network
A
Cheaper uses shared links
Decent failure resiliency through alternate paths
4
Q
What type of network does the internet use?
A
Packet switched network
5
Q
Circuit Switching
A
Connection oriented: end nodes must set up exclusive connection
Guarantees bandwidth and latency
Each link can only be used by one pair of nodes at a time
The oath of connection cannot be moved once established
No circuit available to connect far away nodes
6
Q
Packet Switching
A
Connectionless: each packet is independent Unreliably reliable (Because of protocols)
7
Q
What parts of a network can have queues
A
Intermediate nodes, Routers, Switches
8
Q
What are queues?
A
Congestion - To many packets - causing delay and loss
Packets will be dropped when queue is full
