2 The traditional telco domain and central office data center Mobile Domain Transport Domain MOBILE RAN/Mobile Core IP Edge WAN Telco datacenter DPI AAA PCRF CDN NAT FW IMS RESIDENTIAL ENTERPRISE EvoC Edge PGW DC GW Fabric Traditional telco network with network functions geographically and topologically distributed across different domains and in the primary site central office. Functions are statically linked in the L2/L3 flows. Ericsson AB /31/2013 Page 2 (14)

3 The arrival of cloud: distributed exec environments + V-APPS (NFV) Mobile Domain Transport Domain DC Domain (OpenStack) MOBILE RAN/Mobile Core Virt. zone AAA PCRF DPI IP Edge Virt. zone NAT WAN Cloud DC Virt. zone Virt. zone CDN IMS FW RESIDENTIAL ENTERPRISE EvoC SSR PGW DC GW Fabric Distributed network enabled cloud execution environment allows virtualized network functions (vapps) to move topologically inside the distributed homogeneous exec environment. Cloud domain management becomes a key function Ericsson AB /31/2013 Page 3 (14)

4 Network management and near real time control merge: SP-SDN Network abstraction and cross domain control Mobile Domain Transport Domain OF Controller OF Controller MOBILE RAN/Mobile Core DPI AAA PCRF IP Edge WAN Telco DC CDN NAT IMS FW RESIDENTIAL ENTERPRISE EvoC SSR PGW DC GW Fabric SP-SDN merges traditional network management with near real time control of network status and characteristics, whether in an OpenFlow controlled domain or in a traditional network domain. OpenFlow controls the networking infrastructure inside the cloud DC. Ericsson AB /31/2013 Page 4 (14)

5 Cloud & SDN & V-APPS (NFV) Network abstraction and cross domain control Mobile Domain Transport Domain OF Controller DC Domain (OpenStack) OF Controller MOBILE RAN/Mobile Core Virt. zone AAA PCRF DPI IP Edge Virt. zone NAT WAN Cloud DC Virt. zone Virt. zone CDN IMS FW RESIDENTIAL ENTERPRISE EvoC SSR PGW DC GW Fabric The two distinct technical architectures merge together to create a programmable network enabled cloud execution environment that orchestrates on computing, storage and end to end networking capabilities in traditional and OpenFlow enabled domains and delivers the NFV vision Ericsson AB /31/2013 Page 5 (14)

7 The Network Enabled Cloud Basic premise: Cloud is about an application deployment model: Flexible Virtualized Automated Not strictly about gigantic data centers Manage a collection of data centers of all sizes as single compute/storage/networking resource Gigantic, macro, mini, micro, nano Interconnect with provisioned, high bandwidth links VPNs Location becomes a deployment parameter Country, city, state Ericsson AB /31/2013 Page 7 (14)

8 Efficient resource utilization Adapting to location/crowd specific usage Network wide virtual resources for Resource allocation based on usage Event based relocation of services Improved network efficiency Adapting to time of day service usage Appl Appl CSCF CSCF Auto-scaling for shared resource utlization and power efficieny Relocating an application on the Network Enabled Cloud
