Ottmar Krauss - Nokia Siemens Networks - IP and the optimized wireless backhaul

  1. 1. IP and the optimized wireless backhaulThe ‘state of the planet’Ottmar KraussTransport product marketingNokia Siemens Networks1 © Nokia Siemens Networks Broadband World Forum, September 2011
  2. 2. Packet transformation is happening now Traffic is growing exponentially… The consequence: Global Mobile Traffic Forecast Packet transformation 40 Annual traffic (ExaB) NSN 2009 79% of operators 30 NSN 2011 have plans to go to Ethernet Cisco 2010 (Infonetics 2011) 20 Cisco 2011 10 Informa 2010 ABI 2010 More than 120 of Nokia 0 2007 2008 2009 2010 2011 2012 2013 2014 2015 Siemens customers already use packet transport in HSPA … and unpredictably areas Different times, various locations Suburbs 100% of BTS transport City modules delivered by Nokia Siemens are Ethernet ready Residential 12am Time 12am2 © Nokia Siemens Networks Broadband World Forum, September 2011
  3. 3. Ethernet is the chosen network service –enabled by various types of network architectures Backhaul based on Ethernet services (E-Line, E-Tree, E-LAN) MME eNB Ethernet IP 2G / 3G SAE-GW IP Router BTS (Security GW) BSC / RNC NETWORK & ARCHITECTURE (i.e., the Infrastructure for the Eth services): IP/MPLS, NGSDH, MWR, Carrier Ethernet, DWDM with L2 Switch, PTN, P-OTS Ethernet is the service … … transported over any sort of architecture3 © Nokia Siemens Networks Broadband World Forum, September 2011
  4. 4. But things are never that easy… Differences in: E2e backhaul management is inevitable: • Technology interworking and mapping of services • Architecture and architectures is key • Class of Service structure • QoS implementation • Synchronization • … Network convergence: • Converged GSM/3G/LTE backhaul • TDM / Packet backhaul • Converged mobile and fixed backhaul4 © Nokia Siemens Networks Broadband World Forum, September 2011
  5. 5. E2e packet transport integration:Key to a high-quality, future proof network Mobile Backhaul Mobile Site Mobile Site Mobile Backhaul Connectivity Connectivity Across domains, technologies, SGSN/MME MSS RNC vendors, … GGSN/SAE-GW MGW BSC Resilience, QoS, Multiservice IP Backbone LTE data session service assurance, security, management, … For a flexible, future proof, secure network RNC MGW MGW RNC 3G voice call Mobile Site Mobile Site Connectivity Connectivity5 © Nokia Siemens Networks Broadband World Forum, September 2011
  6. 6. Multi-Layer Optimization:Ensuring smart & efficient transport network evolution Network topology Improved network Optimization efficiency: lifecycle Lower TCO + Improved network Network Layers scalability: Ready for evolution Multilayer optimized network Reduced Latency: + Improved user Network equipment experience6 © Nokia Siemens Networks Broadband World Forum, September 2011
  7. 7. E2e QoS management:a centerpiece of packet transformation Different KPIs for Circuit switched voice Prio 1 different services – based on user profile Minimum bit rate, e.g. business or VIP users Prio 2 and service type and services Best Effort users and services, with priorities and weights between each other Prio 3 E2E QoS provisioning Consistent e2e QoS Policing implementation: Nb • Requirement for efficient resource RNC utilization Nb Policing QoS Marking • Key to optimized QoS enforcement • Priority queuing user experience QoS Marking • Bandwidth reserved for guaranteed traffic 3G Example7 © Nokia Siemens Networks Broadband World Forum, September 2011
  8. 8. E2e Service Management & Assurance:OSS and beyond End-to-end Consistent e2e NMS layer service management across all domains Ethernet connections NMS layer Service assurance Element manager across all network entities Physical Easy and secure Aggregation Connections operation NodeB RNC Example 3G Access Aggregation8 © Nokia Siemens Networks Broadband World Forum, September 2011
  9. 9. Packet Synchronization:Not really an issue any more Primary Over 75 times 1588 ToP 1588 ToP Reference Grandmaster Clock field proven GPS 1588 ToP Boundary / Transparent Clock (phase sync) ~ Over 60,000 BTS Slave in the field ~ ~ Symmetricom eNB Primary Reference Master Clock ~~ ~ ~ ~ Clock Sync Eth Sync input/output options for site Packet Transport NSN is the leader solutions in packet based network synchronization Frequency synchronization Phase synchronization9 © Nokia Siemens Networks Broadband World Forum, September 2011
  10. 10. Summary • Packet backhaul is here – today • Making is work requires an e2e focus • Key topics include: – E2e integration across any domains – Multi-Layer Optimization – E2e QoS management – E2e service assurance and control – Reliable packet based synch Nokia Siemens Networks is here to help you!10 © Nokia Siemens Networks Broadband World Forum, September 2011
