Software Defined Networking (SDN) has been the the hot topic within network infrastructure industry for a few years now. We are now starting to see its influence not only in the data center, where SDN originated, but also within other areas such as core networks and enterprise services. Enterprise services is an area where SDN has real potential to impact services for end users.
Growth opportunities for service providers will come from selling other services (e.g. security) on top of a SD-WAN (especially to the under-served SME segment), and these should be delivered using SDN and virtual network functions. Only by offering additional services on top of SD-WAN will service providers be able to meet the customer requirements and grow their own business.
Any non-US citizen who’s visited the US will have experienced the “pleasure” of US immigration and the long wait to get your passport stamped. When I arrived at JFK airport this week I was happy to get access to the new Automated Passport Control machines that check your passport, fingerprints and take your picture. However, this delight was soon dealt a crushing blow. After leaving the machine, I realised that there was then a manual process to check that I looked like my passport picture and to get my passport stamped. Unfortunately, there was 35 minute wait for this final manual check.
My experience had illustrated how automation can be useless, and even a negative impact, unless 100% of the process is automated.
