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
