A more prudent option might be deploying redundant optical amplifiers, running data on both lines and achieving an optimum load balance. (In this case, capacity is only halved if one line fails.) Or, for the highest security level, all system components – individual fibers, optical distributors, multiplex functionality, etc. – are doubled and deployed in a ring architecture. All single points of failure are eliminated, and the enterprise is protected even in the unlikely event of double fault.
Basel 2 is only one of dozens of regulations that European Union banks, insurers and other financial-services providers are positioning to meet. In fact, the most far-reaching might turn out to be the Markets in Financial Instruments Directive (MiFID).
The good news for IT managers is that they will find substantial overlap among the various requirements, meaning that one secure, high-speed optical networking solution might help an enterprise achieve compliance across multiple regulations. Also, as the UK banks are showing by taking advantage of cheaper real estate outside London, there are business advantages to be gained in separating data centers to improve disaster-recovery capabilities and move toward Basel 2 compliance.
All of this adds up to a promising trend: IT, once viewed as a mere cost accounting center, is coming to be recognized in the financial-services industry as corporate asset – a element of strategic importance in capital-expenditure plans.
