OCC Reference Architecture Fundamentals

•Cloud Services provided over a Cloud Service Connection (cSC)•cSC is a logical entity that may ride over overlay, virtual and physical entities that are provided by single or multiple operator (s)•Cloud Service can include application entities, cSC and associated resources, as well as just the application or just the connection•User interface can be L1, L1-L2, L1-L3, L1-L7•Service frames (packets) can be Ethernet, IP packet, MPLS packet, application PDU

Cloud Services• NaaS (MEF Services, Load Balancing, ELB, Domain Registration

Service, Managed DNS, Network Appliances, IPv4/v6 Capable Dual Stack, Elastic IP Services, Overlay Network Services,..)

• IaaS (Storage Services, Databases, Disaster Recovery, Cloud Computing (Bare Metal Servers, High Performance Computing, Virtual Servers, …) )

• SECaaS (Managed access, NaaS security, Traffic Cleaning, etc.)

• PaaS (Managed application platform, scalable and high performing network, etc.)

• SaaS (On-demand Software Installation, Licensing, CDN, Email)

• CaaS (Virtual PBX, Voice and Video Conferencing, etc.)

NaaS Service Types• EPL, EVPL, EP-LAN, EVP-LAN, EP-Tree, EVP-Tree, IP VPN, L2

VPN: On-demand with SLOs• On-Demand Load Balancing: Local, global, or high availability

LB• Elastic Load Balancing• Domain Registration Service• Managed DNS• Network Appliances (Firewalls, Routers, …)• IPv4 and IPv6 Capable Dual Stack• Outbound Public Bandwidth• Inbound Public Bandwidth• Private Network Bandwidth• Private and Public Port• Elastic IP Addresses• Overlay Network Services: PBB/PBT, L3VPN, VXLAN• Security

OAM for Cloud Services

•Service Availability-• Monthly Uptime of four 9s or five 9s• Unavailable-No external connectivity, Zero read/write

I/O, etc.•Provisioning-Rapid provisioning, resource changing, automated OS reload, remote reboot, etc.•Performance Management-Periodic measurements, TCA, etc.•Fault Management-Discovering and monitoring virtual resources, scheduled maintenance, upgrade events, etc. •Billing-Fixed, Usage Based, etc.•Testing-Verification of attributes of each interface, connections, cloud services
