SDN Technology

The New Wave of IP + Optical Integration

At the Alcatel-Lucent Technology Symposium, Heavy Reading senior analyst Sterling Perrin talks about how SDN has reshaped the discussion around packet and optical integration.

Cyan trials I know this was an ALU talk, but the topic sounded like Cyan's bread and butter.  Wonder which tier ones their trials are taking place at...

Re: Taking integration to the next level Haha, I guess that depends on how well the ball is handled once it gets punted.

Re: Taking integration to the next level Agree wholeheartedly.  I once said SDN is the holy grail of punting device-level interop over the fence.  I'm not sure it's such a bad thing.

Re: Taking integration to the next level When I speak about IP and optical integration, I use the term to include both the physical hardware integration model and the newer software integration of control and management. It is the latter approach that has gained the most interest in the past 2 years and it is this approach that is tied most closely to SDN.

Re: Taking integration to the next level The issues with packet optical are the same they have always been.  People still want IP/MPLS routers and putting optics in the routers is really expensive and usually not very dense.  The optical gear does Ethernet okay but is also not very dense, nobody wants to build their networks using L2 switching, VLANs, etc.  It's always been a metro or MEF Ethernet services play.   As we move to the paradigm of coherent DSP being separated from the analog plugable we may see the density be pretty good on the router side, only time will tell.   To date, Juniper is the only vendor with decent scale with coherent 100G interfaces in the PTX.   The most promising "packet transport" box is the Cisco NCS4K since it will support traditional IP/MPLS along with OTN via an electricla fabric and pure wavelength muxing/transponding like any other optical shelf.  

Cisco and ALU probably have the the best packet-optical integration story because they make both sides.   The integration works as long as you buy your packet and transport devices from them...  They support similar things both with router-integrated optics and also making the optical shelf be a logical extension of the router.  It allows it to look like the router has a DWDM transponder in it but it's really not, so you get the benefits of grey optic density in both platforms.   The key though is making the grey optic interconnect cheaper.  

Their transport systems have good alien wavelength support as well, especially ALU with their wavetracking technology.  In that case the integration will likely happen with controllers speaking to eachother to exchange information on SRLGs, impairments, etc.

Re: Taking integration to the next level I think there are a number of efforts ni the market that could be successful - not sure anyone will dominate.


Apart from ALU and Cisco, look at Ericsson + Ciena and of course Huawei will be in the global picture.

You can bet also that Infinera will be on the scene...

Re: Taking integration to the next level Would not have said ALU will lead this IP and Optics Intergration.  Cisco much better strategy which will see the Cisco dominate in the future this type of effort.

Taking integration to the next level THis is where things start to get really interesting -- when the integration happens at the physical and software/management layers...
