WAN 오케스트레이션 사례 : Bandwidth Scheduling
Programmable
Congested !!
Enterprise customer uses self-service portal to request BW between Data Centers in San Francisco and LA
Result: At the predetermined time, Wave places the demand on the network
① Network conditions reported to collector consistently
② Customer requests DC #1 – DC #2 bandwidth at Future Date
③ Demand admission request: <R1-R3, B/W, Future Date>
④ WAVE returns booking confirmation as Future Date nears
⑤ On Future Date WAVE places customer demand on IGP or explicit path (TE tunnel)

ESP (Evolved Service Platform) 소개 Virtualization
• Cisco cloud service platform for automating, orchestrating and managing virtual services in a multi-tenanted datacenter
• open, standard-based, modular architecture and platform for services orchestration
• Software-only overlay !
• Addresses all layers of service orchestration:
Virtual Services Layer
Virtual Networking Layer
Physical Networking Layer (future, not committed)
Across both NGN and DC domains

ESP Use Case : 가상의 Routing as a Service
• Shared provider network requiring no VPNs
• VPN is not based on MPLS label switching nor VRFs
• VPN is based on virtual topologies done on a per customer basis
• VPN is point and click virtual topology in the DC
• Every VPN is single tenant
• Performance is constrained by x86
