CURRENT SITUATION – ROUTER VIEW

Routers know with whom they are

connected, but have no idea how

they are connected.

Each router needs additional ports

and connections as backup in the

event of optical network failures.

CURRENT SITUATION – OPTICAL VIEW

The optical transport network pairs up

interfaces across geographic distances,

but has no knowledge of the services

being carried.

SOLUTION:

SDN CONTROL

• Combines services

and connection views

• Basis for Multilayer

• Provisioning

• Restoration

• Optimization

ECI Proprietary 5

BA

COMBINED SDN MULTILAYER VIEW

Routers can use the optical network

to manage restoration.

This reduces the number of

expensive router ports and

associated optical connections.

We can do more with less.

SDN MULTILAYER NETWORKING PROMISE

Fast Service Provisioning• Increase customer responsiveness

• Network-as-a-Service (Naas) and

bandwidth-on-demand services

Dynamic Service Restoration• Reduces reliance on dedicated protection

• Additional mechanism to guarantee SLAs

Multilayer Network Optimization • Serve aggregated traffic demand with

fewer resources

• Capex savings

Network Automation• Eliminate human errors

• Opex savings

• Advanced IoT and M2M services

SO THE FUTURE SEEMS BRIGHT?

REALITY HAS

ROADBLOCKS

ECI Proprietary 9

SDN Never Happened

• Being able to configure your

network using (some sort

of) abstract API does not

make them software defined

• OpenFlow offered both and

control plane and (to some

degree) data plane

programmability but never

caught on

• P4 is not in a better shape

• Netconf/YANG is not SDN

“NNI GAP” EXISTS

• Different vendors usually

supply the packet and

optical layers

• Effective SDN multilayer

orchestration requires

exposing the optical (OCH)

NNI data model

• Today this information is

proprietary, due to optical

networking “complexity”

“E-NNI GAP” ALSO EXISTS

ECI POSITION

• Committed to a multilayer,

multidomain, multivendor

SDN ecosystem, based

on code and not (just)

standards

• Have already shared an

ODU model with ONOS,

and are prepared to open

our optical model as well

• Will not happen without

market pull

SUMMARY

• Huge potential benefits from

multilayer SDN-control

• To achieve full potential

optical vendors need to

create and expose a

standard OCH data model

• Particularly needed for

“proactive” control

• Time is against us
