Wide area network
Data center network
Affect to the other
networks
Traffic congestion
(e.g. TCP incast)
Approach
Performance isolation among virtual private clouds
Objective:
Assign different queues at network equipment
Handle various network equipment
Network resource management system (NRM)
Manages bandwidth and topology of physical
network
Allocates guaranteed bandwidth to each virtual
network
