The Datacenter Network Challenge:

Not Optimized for Today‟s Traffic

• Traffic patterns in the datacenter have changed due to

new application designs AND virtualization

– Explosion in VMs

• The network has not changed

• Current network has:

– Multiple Tiers and Uses

– Limitations of Spanning Tree: Slow to reconfigure, adds

multiple layers

• Multiple networks in the datacenter add costs and is

inflexible
