  1. 1. Internal Only▲ Cloud and Network EvolutionXiaodong Zhu ,ZTEBBWF , 2011
  2. 2. Confidential▲Cloud computing provides resources on demand The definition of Cloud Computing “Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.” The National Institute of Standards and Technology Flexible allocation of logically Virtualisation partitioned resources at three service layers Software as a Service (SaaS) Platform as a Service (PaaS) Infrastructure as a Service (IaaS)
  3. 3. Confidential▲Cloud computing is a paradigm shift € € € € € € € € € € Cloud is leveraging the additional bandwidth resources
  4. 4. Confidential▲Cloud centralisation brings benefits in 4 dimensionsCost Reduction Ease of upgradeOptimised use of pooled resources Single location for expansion of resourcesSingle location management and maintenanceSite selection on basis of low costFlexibility Green SaaS PaaS IaaS Optimised use of real estate associatedDynamic allocation and load balancing facilities (power optimisation, air-Ease of duplication for redundancy conditioning, etc)
  5. 5. Confidential▲Where we need resource on demand ? 1 3 Wireless access need a lot Clouded user database of computing power Access Agg. Gateway Core Control Service GGSN/XGW AGCF CCF/ Voice CDNCF SS Multimedia BS CE/PTN SR PTN IP/MPLS MSC CSCF Messaging DSLAM CR Server Business BRAS MDU Mini-OLT WAP Parlay GW USPP/HSS MDU DWDM/OTN OLT Location SN2 4 FTTH may need router As A Telecom service is nature Service to be clouded 5
  6. 6. Confidential▲C-RAN means Centralized , Cooperative , Cloud , Clean Core Aggregation Access CATV Fixed Service Server IPTV softswitch Packet Transport MSTP/SDH/DWDM GE/ Internet 10GE RNC GGSN SGSN MSC Server HLR MGW Mobile
  7. 7. Confidential▲Traditional RAN requires many site buildings Feeder CableA traditional RAN deployment has many site offices to house base station equipment
  8. 8. Confidential▲C-RAN can reduce 90% site rooms Remote Radio Unit (RRU) Fibre to the central office Power Cabinet Central Office Baseband Processor Unit (BBU) Pool
  9. 9. Confidential▲C-RAN reduces energy consumption by up to 68% in CMCC Network O&M, Others, 5%Central Office, 5% Others, 6% 16% Base Station, 48% Site Room, Air- 74% conditioner, 46% Source: Data statistics from a operator 68% Traditional Macro Base C-RAN Station Base station and air-conditioner account for a majority of energy consumption at site room.
  10. 10. Confidential▲Virtualisation can reduce CPE complexity and cost Aggregation network IP Edge Service Platform CPE is necessary as the demarcation point between the operator and subscriber network A considerable amount of functionality can be implemented as virtual CPEs on cloud and middleware platforms at various locations in the operator’s network.
  11. 11. Confidential▲Need carefully plan which functions move to the Cloud FTTH FTTC/VDSL ONT L2 HGW Aggregation network •L3 routing / Forwarding •DHCP •NAT •VOIP ?? L2 HGW ONT •CDN ???
  12. 12. Confidential▲Traditional HLR/HSS is not cost efficient STP STP STP STP STP STP  More Nodes HLR  High CAPEX & OPEX  Complex architecture  Complex configuration OSS Provisioning  High cost redundancy solution
  13. 13. Confidential▲The Cloud is well suited to user profile data storage STP and other Business and Network Other Network Operational Other Management Applications Elements Support Networks System Systems USPP Front End Provision UMT Subsystem OMC Subsystem The benefits of centralised cloud facilities can be leveraged for the storage of user profile data enabling cost reduction in the core network.
  14. 14. Confidential▲The convergence of network and cloud for service creation Information Services Communication Services Services provided by Cloud Computing Software as a Service (SaaS) Platform as a Service (PaaS) Infrastructure as a Service (IaaS) Communications as a Service (CaaS) Telecom Internet Underlying Network Infrastructure
