CarrierSDN

Bandwidth can now be treated like elastic compute, on-demand can be charged at incrementally higher rates.

Getting better + more policy-driven use out of infrastructure allows more on-demand offerings to be supported.

Provisioning used to takes days or weeks... is now automatic, service goes up on demand

@ALU_IPOptics Quote-to-cash is now a click away :-)

Better use of infrastrucutre, as Paul said, but also automation. Bandwidth-on-demand isn't something you can do very well manually (and still be 'on-demand')

Bandwidth no longer needs to be reserved and "wasted" until customer arrives... it is assigned on-demand

@ajcochenour I like you comparing this to elastic compute. The network needs to be the next on-demand service in the #cloud.

Automation definitely key.

We see security as a great compliment to carrier SDN capabilities

Automation helps on the front-end of on-demand too -- more requests with more customer-specific attributes can be activated on-the-fly

Key is: dynamic IP/optical provisioning, network-aware service activation, and optimized placement of new tunnels

making it easier for customer to buy and use network services is good place to start

@craigmatsumoto my analogy is the network is still like cable TV before remote control

Who would Netflix be in that world?

Netflix would be the guy who runs down to Blockbuster, I guess. :)

We see lots of customers' eyes light up when we show how carrier SDN makes BoD viable, and widely deployable

Scott Raynovich @craigmatsumoto I do wonder what the #FCC thinks of #SDN or if they even know what it does.

#CarrierSDN does make Bandwidth on Demand profitable, but needs analytics capabilities for higher predictability #SDN #serviceprovider

@ShehzadKar agreed, #analytics key to everything

Adding capacity to an inter-data center link (or network) to meet temporary higher capacity demands

Makes user experience monitoring/response a reality, poor app performance can drive top-down response instead of old-school EMS-style bottom-up monitoring

recovering stranded bandwidth to enable placement of services that might otherwise be rejected by the netowrk

@hra99 nobody likes their bandwidth to be stranded

we have an agility issue. need to reconfigure resources faster. dynamic-compute with static-networks doesn't work anymore.

Adding capacity for a rapid rise given carrier business unit's increased requirements (ex: just introduced iPhone X and expecting a surge we need to support)

SDN opens the door to fuse together app/network/security layers together that were previously impossible to manage together

Does the @ALU_IPOptics team have any specific customer examples yet?

Network optimization can be looked at in 2 ways - traditional techniques like compression, data deduplication, etc. and app performance management - app QoS, link aggregation, link load balancing, etc.

@raynoLoad balancing/traffic engineering key requirements in carrier netowrks

Curious about network compression? what would that be??

Network optimization is getting more revenue generating traffic from existing assets

.... and it's complicated ... very compute-intensive. thank goodness for the cloud :-)

Batting practice

Still in the parking lot

@pj4cloud LOL. Before a 5-hour game going to extra innings.

@ajcochenour Tailgating! LOL

one can argue we are there (or close) in the datacenter, it is the metro/WAN where we have opportunity now

@ajcochenour @pj4cloud well that's good, it means there's a ton more value to be created here.

Seriously, probably 1st or 2nd inning .. we can do PCE at each layer but not so well together yet .. we can trial auto-deployments in silos but not catalogue-wide yet .. early days

mobile networks are there today - but moving business services/datacenter connectivity/others to this paradigm very early days

80% in 1st, 10% in 3rd

@hra99 Agreed, Heidi. SD WAN represents a solid opportunity.

@hra99 Mobile networks were never given a choice really, there has never been an economy of scale without near-complete automation

Indeed, lots

It's very early, but it's important that we're talking about it. The first rounds of real-world deployments should teach us a lot.

And as @hra99 said, mobile networks do a lot of this already. Pasting the ideas onto the old wireline network is where a lot of the 'fun' is.

Speeds enables new services and service delivery options

Tunes the placement for best alignment with carrier's policies + SLAs

Drives more efficiency in the network, and better network utilization

allows SPs to set up services with confidence - ie, they have assets they need to meet the demands of dynamic service requests

@adamnadeau8 thoughts?

answers my question perfectly!

Ensures SLAs are met while making optimal use of network assets

Even more important is how to do all this as network services become more on demand and more 'transient'

So, it sounds like a big part of this is making networks more responsible and flexible.

makes optimal use of network assets!

Networks can respond to new or changing' conditions without intervention

If the network itself is more responsible, can I get it to babysit my kids?

@hra99 LOL!

@hra99 yes cause automation is the goal

Brings down maintenance costs, enables SPs to scale better and faster, be more agile and elastic; drives simplicity and innovation
