Dimension Data (DD) have released “Network Barometer Report” for last six or seven years. This years report has some interesting data that seems to confirm many of the points that I’ve highlighted on Enterprise IT in speaking and podcasting over the last couple of years.
- Dimension Data has gathered the data from the networks that customer pay them to monitor.
- Dimension Data are a reseller / consultancy. The report is not independent and is strongly slanted into issues that might drive sales.
Obsolete Network Devices
In 2016, the percentage of ageing and obsolete devices in networks fell from 53% last year to 42%. Since 2010, networks had been ageing; this year’s report illustrates that the trend has reversed
The reports explains that “Ageing and obsolete” means End of Life or End of Sale.
As a rough guide, half of network devices should have been replaced but haven’t been.
Vendor Maintenance has Little Value
DD highlights that break/fix support i.e. vendor maintenance is a small fraction of the support required. But this statistic is less than I expect:
As 14% of incidents are caused by configuration error, and 23% to other human error, over one-third of incidents could be avoided with proper monitoring, configuration management, and automation.
My absolute favourite: 8% of network incidents are due to a software bug.
Insecure Networks are Normal
Network devices are well known to be insecure but no one does anything about it.
To make things worse, the top reasons for vulnerabilities that have been known for YEARS.
SDN Isn’t Happening
While I agree, I suspect that the SDN definition at Dimension Data is focussed on just a few vendors and the company itself hasn’t embraced SDN. If I was working for a reseller and constant need to make sales and profits in this quarter I wouldn’t be too keen on SDN either.
We see intense market interest and testing, and expect widespread adoption of software-defined WAN technologies which will lead to a migration of data centre aggregation routers and branch/edge routers in the coming year.
The EtherealMind View
I’ve picked out elements that seem relevant to me. Its a sad picture of networking in general that many of devices are obsolete, insecure and difficult to own.
