Blame the System For Resisting Change – Not The People

I often hear vendors and pundits proclaim that Enterprise is resisting change. In particular, they say that individuals in Enterprises can’t see the change or won’t discuss buying new technology. I see these objections as failure of the current system and much less due to the people.

Big Switch Networks Launches Mature Hardware-Centric Data Centre SDN Solution

Big Switch Networks (BSN) launches Version 4.0 of Big Cloud Fabric for hardware-centric SDN data centre fabric. The Data Centre Fabric solution clearly shows the maturity gained from 5 years of shipping products while adding innovation in switch hardware through Switch Light operating system. At the same time, they have completed the transition from platform to product. A product that really has what you need in a hardware-centric SDN platform and addresses nearly all of the issues the competitors have not addressed. And it is shipping now.

Mellanox and bad CLI choices

I’ve been working on Mellanox S-Series switches lately in a largish network with several hundred 10GbE server ports. On the whole, the product has performed beyond my cynically low expectations and the product has good capabilities overall but the command line interface (CLI) is a really poor user experience. How about this gem for configuring […]

SDN Started as a Customer Movement (Not a Vendor Innovation)

With the vast marketing budgets from big vendors and their well paid “evangelists”, the startups vying to introduce new methods and the clamour of engineers trying to understand new technology it might be time to pause and remember that Software Defined Networking was a customer-driven initiative. Vendors had to be forced to accept that SDN was a necessary change.

Response: RFC 7045 – Transmission and Processing of IPv6 Extension Headers

IETF RFC  on the Standards Tracks that talks about the problem of chaining headers in IPv6. I’m getting a sense of deja-vu since this was also has issue with IPv4 and, ultimately, use of chained IPv4 headers died away. If they encounter an unrecognised extension header type, some firewalls treat the packet as suspect and drop it.  Unfortunately, […]

Response: IP PBX sales decline 10% | Dell’Oro

The IP PBX business is shrinking as mobile phones replace desk phones. More importantly, voice calls are replaced with chat applications like Skype, FaceTime, SnapChat. Modern companies are using messaging platforms like Slack to replace time wasting telephone calls – we run the Packet Pushers business zero telephone calls. I’ve been predicting this for a year […]

Scripting Does Not Scale For Network Automation

Lots of people claiming that scripting works for automation and, for a few scripts or tasks, you can get a lot done for not much effort. My experiences with scripting have left me bitter and jaded. Here is why.

My Private Cloud Block Architecture Diagram

When planning network architecture for the next few years,  I believe that it is important to comprehend that the network is just a one part of an overall system. The ITIL foolishness that drive most IT infrastructure processes prevents clear systemic thinking and I'm often having to explain how the … [Read More...]

Blessay: The Internet is a “Cloud” for Networking

Can the Internet be the “Cloud Network” ? If so, when could the transition happen (if it hasn’t started already) ?

Book Release: Tips on Using Visio To Make Network Diagrams

Back in 2009, while working on a network diagram in Visio, a fellow worker asked me to show him how I did certain things. I thought this a bit strange at the time, but when other co-workers started asking the same questions I was surprised. Some of them got quite excited and said nice things and it … [Read More...]

VCE chooses Cisco ACI as SDN Strategy Instead of VMware NSX

Lede: I doubt that anyone bought a Vblock because it was a market leading networking strategy. I've been a supporter of VCE in the past but I'm doubtful that choosing Cisco ACI is good strategy for customers. My view is that most customers buy VCE Vblocks as a VMware platform. What VCE offers is a … [Read More...]

As a result, it is planned to last for two, maybe three years before it will be replaced. From this project I learned that … [Read More...]
