- Five Deadly Sins of Incumbency « Ineluctable Modality – I really enjoyed this article from Alan Cohen (who recently joined Nicira).
Your customer relationships and brand are the moats competitors need to cross in any competitive market. However, make sure someone has not moved the castle. In today’s economy, all advantages are perishable, time-allocated assets. You don’t want the 5 sins of incumbency transposing you from the secure position inside the castle to the exile on the road out-of-town.
He makes good points about the problems of being an incumbent.
- OpenFlow Tutorial: Next-Gen Networking Has Much To Prove – Infrastructure – Network/systems management – Informationweek – Jeff Doyle talks about OpenFlow:
Server virtualization is now a proven practice, creating a cost-effective means of allocating compute resources to changing user and application requirements. But when packets leave the server, they still pass through a traditional switching architecture, which doesn’t have that same level of flexibility.
- Will OpenFlow lower your phone bill? — Tech News and Analysis –
Elby described more options, but the message underlying his talk was that OpenFlow and software-defined networks could lower Verizon’s costs, but it also turns Verizon into a service provider with a change in the type of cost model it will have. Understanding the technology as Verizon implements it and how it will change its spending on equipment and operating its network is one thing. Understanding the new business models that Verizon can implement as it provides what can become a multi-tenant, shared network model even for enterprise clients is another. It’s going to be fun, but I’m not sure if it will actually result in a lower mobile phone bill.
- 5 Rules for growing your SE « kontrolissues –
After reading Greg’s Ferro’s hilarious blog on fashion tips, I thought I would add my own experience and put together 5 rules for Account Executives ( aka. Sales Guys ) to follow when helping their SE’s ( aka. the brains ) to do put their best foot forward. Part of your job as our handler is to make sure that you mitigate the little eccentricities that get in the way of the dashing brilliance that we unleash in each and every meeting you bring us into.
- Google Apps Not Cutting It for LA’s Finest | Wired Enterprise | Wired.com – The road to the blah blah cloud is not smooth. Or even possible.
Two years after the City of Los Angeles approved a $7.25 million deal to move its e-mail and productivity infrastructure to Google Apps, the migration has still not been completed because the Los Angeles Police Department and other agencies are unsatisfied with Google’s security related to the handling of criminal history data.
- Cisco FabricPath for Cisco Nexus 7000 Series Switches [Cisco Nexus 7000 Series Switches] – Cisco Systems – Good looking White Paper on Fabric Path from Cisco. Download it in PDF format before they remove it or try to find a way to make you pay for it ( licensing ? )
- Good CoPP, Bad CoPP – Balanced Policing « Jim Leach – I’m working with Jim in a Cisco Testing lab at the moment. He writes about another project and CoPP. Good stuff.
What I didn’t realised was that IPMCMISS doesn’t actually [just] match RPF-failing traffic – it actually matches any multicast traffic that triggers a ‘FIB-miss’ – this was the ‘bloody hell’ moment. Whenever we receive multicast traffic into hardware, and there’s no hardware-programmed FIB entry, it’s a FIB-miss – and this is punted to CPU for processing or software switching. FIB-miss would be triggered the first time we see an (S,G), which is how we get into the process of punting to CPU, PIM learning, inserting into MRIB, generating a PIM Register and programming the hardware. So by cutting away the bandwidth available to IPMCMISS, I was also reducing the chance of new (S,G) frames making it to the CPU for learning.
- Cisco ACE Gets IPv6 Support « The Data Center Overlords – Tony covers the ‘soft dick’ announcement that Cisco ACE supports IPv6 on new hardware only.
Honestly, I’m very underwhelmed by the Cisco ACE product line lately. They’re pretty far behind the competition (F5, A10, Citrix NetScaler, Radware) in terms of features, and Cisco doesn’t seem to be doing much about it. Don’t get me wrong, it’s fine for what it does. But other companies are innovating, and Cisco seems to be content with letting the ACE lineup stagnate, just like they did with the LocalDirector and the CSS. I’d like to see Cisco up their game with true content logic (like F5′s iRules). But considering Cisco discontinued their line of XML Gateways/Web Application Firewalls, it seems pretty unlikely they will.
Agreed. Cisco has given up on anything more than forwarding packets and frames.
- No Interference: Open Networking Summit Day 2: Cisco says “We see SDN as the next evolution of networking” – Network World finally catches on to a trend
I have to say that after an amazing Day 2 at the Open Networking Summit, I am convinced that OpenFlow and Software Defined Networking (SDN) are not only here to stay, but they will define the future of networking. I speak to a lot of enterprises about Software Defined Networking, and outside of the academic and development communities; it is still a new and somewhat unfamiliar term. With the protocol soup of new technologies being launched into the enterprise space, some may wonder how I can be so bullish, and the answer is simple: I just spent the day listening to nearly every major technology company, web portal, carrier and the leading academic researchers in networking, and they laid out an iron-clad case.
An excellent summary of the position of each company.
- Cisco Blog » Blog Archive » STP is not the problem, but FabricPath will fix it!– A very good summary of the value of TRILL that also highlights the fact STP will continue to live on.Sadly, for all my love of ECMP technology ( even including Cisco’s proprietary FabricPath version), I do not believe that it is has much future. Most likely it’s obsoleted by SDN/OpenFlow.Also – best ever definition of Cloud
If they can’t run STP properly, they’re going to open even more loops… Cloud of smoke.
