Assuring Superior VNF Performance at the Network Edge
- 1. Assuring Superior VNF Performance at the Network Edge Introduced by • Lance Hassan, (Director, MEF) Principal Engineer, Time Warner Cable Business Class • Matt Kennamore, Network Consultant, ADVA Optical Networking • Ulrich Kohn, Technical Marketing Director, ADVA Optical Networking 1
- 2. Proof of Concept Description Real world scenario: from connectivity services to managed network services Open protocols and open-source software for seamless integration One-click VNF provisioning Consistent service assurance across connectivity network and VNF infrastructure 2
- 3. OPEX/CAPEX-Friendly Business Growth With NFV 3 CPE solution #9 Functionality Capacity 50 Mbs 100 Mbs 500 Mbs 1 Gbs Hardware Appliances CPE sol. #8 CPE sol. #3 CPE sol. #4 CPE solution #9CPE sol. #2 Functionality Capacity 50 Mbs 100 Mbs 500 Mbs 1 Gbs NFV Approach CPE solution #7 NID High- performance server NID Moderate- performance server NID Painless business growth with NFV – expanding features and capacity without need for site visits
- 4. Enterprise IT Complexity 4 Enterprise Metro Network Carrier Ethernet Communication Service Provider Router NID Core IP-MPLS Servers e.g. video FirewallWAN Optimizer • High equipment cost • Labor-intensive installation and maintenance • Lack of flexibility • New features require new hardware Problem Statement
- 5. NFV – A Solution to Enterprise IT Complexity 5 Enterprise Metro Network Carrier Ethernet Communication Service Provider vRouter Core IP-MPLS Servers e.g. video vFirewall vIDS • Single CPE • Faster turn up for new services • Operational savings / reduced truck rolls • Reuse of virtual equipment / VRF licenses Solution FSP 150 ProVM with integrated server FSP 150 ProVM
- 6. Software Appliances Simplify Operations 6 Agile service innovation with single network element at customer site
- 7. ProVM Architecture – Combining Hardware-Assistance With Flexibility of VNFs 7 Tight integration between server and physical switch / demarcation technology Offloading of forwarding creates room for revenue- generating appliances
- 8. OAM Challenge With NFV End-to-End Performance Management 8 CSP - PoPEnterprise Server / NID Metro/Access Network Rich set of metrics for connectivity network – lack of respective functionality with IT network functions vFWvOptimizer Service OAM (802.1ah) TWAMP Metrics: MFD, IFDV, and FLRMetric: uptime
- 9. Hardware-Assisted Performance Assurance ProVM Architecture 9 Hardware probes for non-intrusive service monitoring • Hardware probes remove need for software monitoring • Server failure does not impact OAM capability • High-precision time information (e.g., banking) • End-to-end visibility across all network layers
- 10. FSP 150 ProVM Multi-Technology Edge NFV 10 • NFV X86 server • Intel high performance 4/8 core processor • DPDK / SR-IOV • PCIe / SSD Slot - optional HW • Hardware-assisted server monitoring and control • Software • KVM Hypervisor • Open Multivendor VNF Support • Integrated into OpenStack • ADVA Neutron plug-in • Proven FSP150 L2 features • SOAM, TM, PM, SAT • I-Temp, 2x PSU, high availability • SyncE, PTP, sync assurance • Additional L3 capabilities • ACL (L2-L4) • IP static forwarding • VRF-lite / DHCP relay • TWAMP • Open programmability • Control ACL & VRF from OpenStack • OpenFlow interface • Comprehensive ConnectGuardTM security suite • ConnectGuard MACSec encryption • Full key management Carrier grade NFV with most comprehensive edge NFV feature set
- 11. Summary • Service providers need to replace manual processes by automated provisioning • NFV as enabling technology, open protocols and open source software as catalyst • VNF service assurance is mandatory for achieving operational cost targets • Combining physical and virtual network functions creates optimum solution 11 Questions?
