“We deceive ourselves when we fancy that only weakness needs support. Strength needs it far more.”
Anne Sophie Swetchine.
We’ve been extolling the virtues of SDN for some time now. But how about possible weaknesses?
In an earlier post entitled Carrier SDN we discussed the potential reduction in time to market (TTM) in a software definable network. Innovation at the speed of software as it were.
However, I fear this adaptability could actually be a double-edged sword.
In another earlier post entitled Ruthless Simplification we discussed the need to keep things simple, the need to reduce the number of variables that the B/OSS needs to deal with.
The current network approach sees CSPs dependent upon their standards bodies and vendors to make decisions relating to new services or features on behalf of the whole industry. This slows down TTM, but it also significantly reduces change and variability, not to mention the extra rigour that generally goes into each new incremental change.
Are we creating a Frankenstein of unlimited change? I look forward to seeing what mechanisms the CSPs need to put in place to put controls around this variability. It’s strength also needs support.
