NFD9 Prep: SD-WAN

Software Defined WAN, or SD-WAN, looks to be a theme of Network Field Day 9, with presenters such as CloudGenix and VeloCloud showing us their offerings. At first glance, SD-WAN sounds pretty compelling. Who wouldn’t want to slash their WAN OpEx? How do these solutions work, and do they have legs? I’m hoping to find out. […]

Just a quick note to say that Big Switch have updated their demo lab system. This is an entirely virtual lab environment that simulates a Big Switch network. You can try out both Big Cloud Fabric and Big Tap Monitoring Fabric. The lab gives you full CLI & GUI access to a sandboxed environment, with […]

Don’t Underestimate Your Users

The “consumerisation of IT” has an interesting side-effect. Historically people mainly used computers for work. But now that many people have smartphones, tablets and laptops at home, their perception and understanding of technology has shifted. Old assumptions about training required when upgrading applications or client operating systems may no longer apply. This comment at The Register aligns with what I’m […]

NFD9 Prep: NetBeez

I’m reviewing the presenters for Network Field Day 9, in particular looking at those I’m not familiar with. NetBeez is one of those making their first Tech Field Day appearance. NetBeez We all know that our users and the applications they access are incredibly distributed. We don’t control all the network elements, but the network […]

Headwinds, or Uphill?

As some of my readers know, I’ve done a fair bit of bike touring. Two of the challenges of bike touring are riding uphill, and riding into headwinds. Riding uphill is tough. 2,300m passes in snow, or 3,200m passes in sunshine, it’s tough going. But you put your head down, and keep turning the pedals, […]

Network Field Day 9

I had a fantastic time at Network Field Day 8, and now I’ve been lucky enough to be invited back to NFD9 this February. As usual, the Tech Field Day crew have put together a great mix of vendors. I particularly like the look of the SDN WAN-focused vendors, such as VeloCloud and cloudgenix. Much of […]

Resources for learning HP Comware

HP is making more resources available to help with learning Comware. They’ve added free labs and courses to the already published simulators and virtual routers. This is a good resource for those looking to get started with Comware. HP Network Simulator (HNS, aka Simware) HP’s Network Simulator (HNS) is a modelling tool for simulating HP Comware networks. It includes […]

Rate my IOS?

Review schemes are useful for identifying good consumer products and applications. But that doesn’t mean that everything needs to prompt me to leave a review. Cisco has started prompting for reviews for IOS versions, but I’m not convinced it makes sense for network operating systems. Perhaps it will do one day when disaggregated hardware/software is the norm for network devices. […]

Big Switch Chaos Monkey Network Testing

Whenever you build a complex system, you need to test that it works as expected, including properly handling failures. It’s easy enough to do simple component failure testing, but harder to do rapid automated failure tests. Big Switch is showing that it can be done though. Hopefully we can keep improving our testing to pick up […]

Operations Manager to OMi Migration Path

HP has finally announced a migration path for Operations Manager to OMi. It’s about time too. This looks like a good path. If you want to stick with HP Software for managing your services, you should be investigating it. The writing’s been on the wall for a while. HP has stopped investment in Operations Manager. I asked […]
