Q
2 Things that need to be measured
A
- Topology: manually entered by network admin
2. Traffic: measured with simple counters
2
Q
2 ways control is implemented
A
- Adding link weights
2. SDN
3
Q
In inter-AS multipath, what properties of the paths need to be equal in order to allow multipath over those paths?
A
- LOCAL_PREF
- AS_PATH length
- MULTI_EXIT_DISC
4
Q
3 Goals of TE
A
- Predictable
- Limit influence of neighbors
- Reduce overhead of routing changes
5
Q
What does fabric manager do?
A
It takes the AMAC response from an ARP query (a host giving its IP-> AMAC response), and the FM translates that AMAC to a PMAC.
6
Q
2 goals of valiant load balancing
A
- Spread Traffic Evenly across the servers
2. Traffic load balanced INDEPENDENTLY of location
