  1. 1. What Type of Network Intelligence is Needed in Next Generation Access Networks and Where?Issued by Iskratel; All rights reserved The case for intelligent access Janez Öri, FTTH Conference, Milano, 10.2.2011OBR70121a
  2. 2. Agenda  NGA business model challenges  Fundamental changes in telco service delivery  How trends influence on NGA active network requirements  Why network intelligence is needed?  What type of network intelligence and where?  Intelligent Service AccessIssued by Iskratel; All rights reserved  The answer for sustainable NGA deployment 1
  3. 3. NGA business model challenges  Investments in fiber acces or next generation access (NGA) networks are CAPEX intensive  Current Telco business model  Vertical services  Flat rate unlimited broadband access  Problems with take-up rate  Money just from the end customer  Difficult for investors (network providers) toIssued by Iskratel; All rights reserved capitalise all the socio-economic benefits of high- speed fiber access networks 2
  4. 4. “Dumb Pipe” broadband model Over-the-top providers offer more & more services.Issued by Iskratel; All rights reserved Q: What can a network provider do? Nothing… Sell more bandwidth… Modify business model… 3
  5. 5. Change of business model  Fiber access networks will require change of business model based on following simple business ideas:  Percieved value of different services and applications (which run on high speed broadband network) is different to different customers -> Network intelligence for QoS differentiation and charging of services per customer based on her/his prioritiesIssued by Iskratel; All rights reserved  Value of network is higher with more customers and services running on it -> Shared investments, wholesale, open broadband networks, “virtualisation of networks” 4
  6. 6. Issued by Iskratel; All rights reserved Customer IP/Ethernet Service Network Internet Internet VoIP IPTV IPTV VoIP Customer Ethernet Services/Applications Internet Tablets IPv4=> IPv6 IP session A Telco services IP session B IP session C Content Providers Sm@rt phones E- servicesMedia TV /NTB Network Provider (L2 wholesale) Telco world is changing on several layers
  7. 7. IP sessions based network intelligence Customer side Subscriber managment Services/Applications AAA, Policy, DHCP, MN, (Self)provisioning Internet IP sessions Telco IP sessions Services IP sessions Content ProvidersIssued by Iskratel; All rights reserved E-Services 6
  8. 8. Where to implement network intelligence?  Network Service delivery is an end to end story, but the network can be divided in two main functional parts:  Subscriber Service edge  Subscriber service profile  Application aware  Controlling IP sesssionsIssued by Iskratel; All rights reserved  Reliable packet transport according to SLA 7
  9. 9. L3 vs. L2 service edge  L3 service edge (subscriber  L2 service edge (subscriber and application aware) and application aware) + needed for ISPs and L3 VPN + Needed for next generation services wholesale, open access - How to control bottelnecks in provider provider, business L2 the access, aggregation, VPN services backhaul? + In Access or Aggregation (for - Scalability and price (growing legacy access nodes) bandwidth, number of + Service provisioning close to the sessions to control) customerIssued by Iskratel; All rights reserved Solution: Distribution (of + Enchanced network security functions) and simplification and QoS control + Lower network CAPEX and TCO 8
  10. 10. L2 Service Edge Architectures Network provider Service provider MPLS transport L2SE 1:1 VLAN CPE Access Aggregation Distribution Possible placement L2SE for L2SE CPE Aggregation Distribution Access L2 service instances, E-Line, E-LAN servicesIssued by Iskratel; All rights reserved L2SE L2 service edge, per subcriber service control and provisioning, MPLS (or PBB) packet transport only, no per subcriber service provisioning or operations
  11. 11. Moving intelligence to the access (ISA)  L2 (Ethernet) service edge:  QoS (bandwidth, priortiy) per subscriber per service per service/application provider  Advanced VLAN “manipulation” • i.e. different types of QinQ, VLAN remarking, multicast VLAN  IP session (application, service) awarness and high access list scalability (needed for QoS, security, accounting actions) based on L2, L3 L4 header information  AAA (Authentication, Authorisation, Accounting) client  Profile (subscriber, service) based provisioning of L2 networkIssued by Iskratel; All rights reserved services  More in the future 10
  12. 12. What are the key benefits of ISA?  Lower CAPEX due to less complex aggregation (and IP edge in some cases) equipment:  Network Provider for L2 wholesale services  Open Access providers  Vertically integrated network and ISP providers  Lower OPEX due to easier e2e QoS and subscriber service provisioning (just on subscriber port)  Abillity to innovate and develop advanced business models for network providers (OTT and Telco synergy)Issued by Iskratel; All rights reserved  Abillity for advanced business connectivity on universal access platform 11
  13. 13. Conclusion  NGA networks are not just about new physical layer  Innovative (and new) business models should have innovative network features  The right active network architecture is the keyIssued by Iskratel; All rights reserved part of the NGA network 12
