I’ve made my own handwritten font for those moments when you are “sketching” network diagrams and it is free for you to use.
Cisco announced another 6000 job cuts in the Q4 2014 Results announcement yesterday in addition to the 5000 job cuts announced last quarter. Cisco has (or had) approx. 75000 employes so that’s a lot of jobs (more than 20%) in a short period of time and this leaves me pondering the impact to the products […]
Huawei is showing some signs of maturity in the Enterprise market with this Learning website offering free e-learning courses. Unfortunately, it’s seriously restricted to partners or some other weird criteria for membership. Entitlement E-Learning courses currently face to the following types of users: Huawei channel partners; Huawei Authorized Learning Partner(HALP) and the one who passed […]
I’m often told that the enterprise customer will take years to implement Private Clouds because the enterprise is slow to adopt new technologies. Yet the private cloud is happening faster than seems practical and there has to be a reason that is driving adoption so quickly. It’s simple, point to the success of others and use that as proof of success and use that to generate permission to implement change.
I collect data from three different research . This is much higher and sooner than my previous survey data in December 2013 and more recently for InformationWeek. Clearly, SDN demand is much greater than almost anyone predicts. Are people talking to the wrong sources about the future of networking ?
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.
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 […]
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.
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, […]
