PROBLEM STATEMENTTodays networks

Current Networks

Control Plane Split

Abstraction

Programmability› Monolith of proprietary technology

› HW vertical integrated (HW, embedded SW, NMS) within each vendor

› Multi-vendor environments usually built using geographical separation

› Industry innovation pace limited by vendor life-cycles

PROBLEM STATEMENTSOLUTION WITH sdn

Ericsson Internal | 2013-07-16 | Page 5

PROBLEM STATEMENTSOLUTION WITH sdn

› Greater feature velocity from vendors

› Services deployement independent from physical network deployment and life-cycle

› Lower OPEX due to central provisioning & management

› API for service creation and exposure

› PCRF› Aware of the subscriber profile

› It will trigger Service Chaining towards the BBSC when it receives event notifications from the P-GW

› DPI› Used for advanced application analysis and triggering

towards BBSC

› NMS› Can be used to manually configure the BBSC

› BBSC› The broadband services controller is responsible to

define the service chains

› E-ODL› Ericsson OpenDaylight SDN Controller, configures the

open flow network

› EFS› Open Flow Switch, forwards the flows and packets
