Problems with the Network • Surely it’s just plumbing? – The network is essentially hidden from the business • We’ve already spent loads on it – what more could be done? – 10Mb to 100Mb to GB to 10GB won’t necessarily solve the problem • It’s just cables, isn’t it? – Perceptions of the network tend to be basic • We’re not doing anything too special on it, are we? – Lack of understanding © 2009 Quocirca Ltd

The network challenge
© 2009 Quocirca Ltd
• Data growth – Internal and external data volumes growing massively – Value chain issues must be dealt with • Convergence – Not just all forms of data, not just voice, but video as well • More video traffic than data already on the internet • 90% of all traffic will be video by 2012 (Cisco) • Latency – Speed of light is a (major) limitation – But latency may not be the problem • “Saw toothing” due to unmanaged bandwidth • Jitter due to poor network utilisation

Network optimisation • Ensure you know what is on your network! – If you don’t know, you can’t do anything – What mix of pure data, voice, video do you have? – What’s important to the business? – Understand whether it needs to be real time, near real time, or can cope with being relatively asynchronous • Filter out the rubbish – iTunes, FaceBook, YouTube, iPlayer may not be the most important things for your business • Allocate bandwidth via virtual networks • Use QoS/PoS, with MPLS as a backbone • Use wide area network acceleration technologies © 2009 Quocirca Ltd

Conclusions • The network is far too important to be left to chance • The network is the foundation for everything else – You wouldn’t build a house without good foundations • Tools have to be in place to know what is on the network • Monitoring and measuring give the capability to control • Don’t forget the external aspects – the value chain is all important
