  • 8 Setting the Scene Why Cloud for Telecom Operators
  • 9 The importance of Cloud Services to Operators  Eagerly seeking services: A strong desire to make money out of cloud market  Traditional sources of revenue (communications services) are declining, especially in developed markets  According to Heavy Reading study early 2012 with 149 operator respondents: • ~60% of operators are familiar with cloud • ~80% of operators have a cloud evaluation team in place • 55% already purchased cloud technology • >40% of operators have already launched multiple cloud services  Cloud services are a big driver for SDN and NFV
  • 10 Future of Telco Business Linked to Three Emerging Technologies  Virtualization • Abstracting networking software (functions) from dedicated hardware and running in virtual machines on COTS platform • NFV initiative specifically is about consolidating many network equipment types onto standard high volume servers, switches and storage in a cloud (ie elastic, resource pooled, orchestrated ) environment  Software-Defined Networking • Creates network abstractions to enable faster innovation • Using virtualization techniques, e.g. network overlays to create programmable data center networks • Using protocols/technologies such as OSS/orchestration and management systems to create programmable WAN  Cloud • Layer of automation/orchestration on top of virtualization that provides NIST cloud characteristics • Distinction emerging between “resource cloud” and “application management cloud”
  • 11 Network Function Virtualization (NFV)
  • 12 Network Function Virtualization
  • 13 ENTERPRISE SERVICES Evolved Packet Core (PGW/SGW/MME/GGSN) M2M SERVICES VOLTE SERVICES (IMS,TAS,RMS) SERVICE MONITORING Network Infrastructure (Access, Transport, Routing/Switching) SMART NETWORK POLICY CONTROL` Common HW Infrastructure distributed across data centers, where NW nodes become Applications
  • 14 • Virtualization of Mobile Core Network and IMS • Virtualization of CDNs (vCDN) • Virtualized Network Functions and Cloud Computing Infrastructure • Virtualization of Mobile Base Station • Virtualization of Home Environment • Virtualization of the Enterprise (vEnterprise) • Virtualization of service chains (Firewall, NAT, security, load balancer, DPI, 3GPP functions, various forms of gateways, etc) • Cloud service exposure to a 3rd party NFV Use Cases (Source ETSI)

  • 32 Amdocs Online Charging System OCS is part network, part IT, part business  These are not packets, this is money It is challenging:  Highly sensitive to latency  Network grade high availability  Highly tuned and hardware optimized A lost event, is a lost dollar
  • 33 Virtualizing Amdocs Online Charging System SUCCESS • Virtualized OCS results are on par with the physical deployment A joint VMware and Amdocs certification was held • Physical environment compared to virtualized • Production like, high loads We had some concerns • Virtualization may add latency overheads • Separates OCS from physical hardware • Real time aspects of continuous processing !

  • 39 From Controller to Radio Network Platform Virtualization One application Dedicated hardware Multi - Tenancy • Cloud in a box Hardware independent scalable platform supporting multiple technologies • Flexibility From small single technology to large multi-technology controller • Cloud on a disk Software only solution can be deployed in existing data center • Seamless capacity and scalability Cloud architecture SW HW RNC RNC RNC RNC
  • 40 Wireless Cloud Element Feature Roadmap Leverage benefits for Network Function  Multi-Tenancy – GSM, W-CDMA, and LTE applications share physical resources  Horizontal Scalability – number of CPUs controls capacity (flexible configurations)  Elastic Capacity – the capacity of the system can change quickly according to need  Reduced Power Usage – as capacity breathes throughout the day hardware can power up / down  Geographic Redundancy – a fault in one location does not disable the system  Zero Downtime Maintenance – VMs move to other hardware for maintenance Sub-Urban Dense Urban Rural As traffic shifts during the day ... ... server load is uniform RNCRNC
  • 41 Transformation from 9370 to WCE RNC  The WCE virtual RNC needs to scale horizontally to much larger capacity than possible with the 9370  Two problems must be addressed: • N2 Communications • Scope of Failure  Reorganization of existing 9370 code allowed for the creation of a component responsible for cells and another responsible for user equipment (UEs)  As UEs (and UMUs) are independent of each allowing for horizontal scalability  The scope of failure is greater reduced as UMUs don’t require sparing WCE vRNC Virtual Machines Current 9370 RNC Application RAB U-Plane GTP/RLC MAC TMU U-Plane RPM-Cell C-Plane NoB CP C-Plane UE CP CMU UMU U-Plane GTP/RLC MAC C-Plane NoB CP U-Plane RPM-Cell C-Plane UE CP VxWorks on Linux VxWorks CMU UEU UEU UEU UEU UEU UEU UEU UEU UEU UEU UMU UEU UEU UEU UEU UEU UEU UEU UEU UEU UEU UMU CMU CMU CMU Cells (spared) Mobiles Scale to 10000s of Cells Scale to 100000s of Mobiles
  • 42 Wireless Cloud Element – 3G RNC Architecture  RNC Components:  Spared Roles (SWACT in a few seconds): • CMU (N+M) – Cell Management • 3gOAM (1+1) – OAM termination • PC (N+1) – Public / Private network gateway  Unspared Role (Return to capacity ~ 60s): • UMU - UE Management (UE Call) & RAB UE Packet processing  Platform Components: • vCenter Server – VM Management (VMware) • LRC Mgr – Tenant Management (unspared) • Disk Access – NAS Front End to SAN  Each RNC component represents a single virtual machine UMU U-Plane GTP/RLC MAC NI SCCP C-Plane UE CP CMU U-Plane RPM-Cell NI M3UA SCTP C-Plane NoB CP Iub/Iur/IuCS/IuPS Signaling PC PC NAT Common Channel Traffic Iub / NBAP Dedicated Channel Traffic vCenter Server LRC Mgr 3gOAM PC Control OMU Netconf Disk Access
  • 43 RNC Real-time Requirements  A controller’s user-plane components typically need very precise timing, e.g.  The RNC must send downlink packets such that they arrive at the NodeB within the Time Of Arrival Window  When the user goes into Diversity mode the RNC’s transmit window must compensate for different transmission times  Six NodeB may be involved in a single user’s connection which currently reduces the RNC transmit window to 5ms 147 148 149 150 151 152 CFN CFN Early OK Late Too Late TprocTOAWS (50 ms) Node B CFN Node B CFN Node B SRNC
  • 44 Non-deterministic Timing  Deterministic timing not possible within a virtualized / cloud environment  Virtualized Network Functions must compensate for timing uncertainty  Data for this chart was extracted from the virtualized RNC while running an hour long traffic test  Note: this system was running with ESXi 5.1; significant improvements are expected from ESXi 5.5
  • 45 Interval Scheduling  Interval scheduling allows for variable amounts of time between events  At each event an accurate time reference is read and the interval between events is calculated  Based on the elapsed time and the priority of work that needs to be done a work schedule is created that ensures isochronous work is completed first at the potential expense of background work
  • 46 Shadow Network Functions  WCE provides the capability to create a “shadow” of a network element within the same physical hardware as the service providing network element  This shadow can be used for: • Fast and Graceful Reset • Software Upgrade • Software Configuration Change • Virtual or Physical Machine Change • Geo-Redundancy  Roll-back to the previous version is possible after an upgrade RNC iBTS RNC Core Network RNC
