Problem of general virtual private clouds

Virtual private cloud # 1 virtual private cloud # 2

Security isolation Physical network Virtual networks

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 Orchestrate with VM provisioning

Network resource management system (NRM)

 Manages bandwidth and topology of physical

network

 Allocates guaranteed bandwidth to each virtual

network

NRM for CPE NRM for switch A NRM for switch C NRM for virtual switches NRM for router NRM for switch B

Orchestration mechanism among NRMs

This model needs time and costs to develop new NRMs.

Problem to handle multipoint network

 NRMs can support only point-to-point provisioning

 Full-meshed path provisioning  Bandwidth arrangement among paths

Problem of NRMs

NRM for router1 NRM for router2 NRM for switch1

Conventional NRM Control drivers are embedded. Control drivers are developed independently.

CHAMELEON software architecture

 CHAnging MEchanism of software moduLE based on

the cONtext (CHAMELEON)

 Install control drivers

 without any modification of NRMs  under the operation of the NRM

 Keep the control drivers as cache Repository server Universal socket router1 router2 switch1
