Although not immediately obvious, the FirePOWER Series 3 devices can do a form of IPS on a stick. This means that the capability described here should be available to the current appliance versions of the FirePOWER managed devices. The premise involves connecting broadcast domains (VLANs) to bring the managed device inline between the initiator and responder of a flow. Configuration is fairly straightforward but does have some caveats.
Caveats
The diagram shows two devices in the same VLAN (we will assume /24 for the configuration). The device on the top is in VLAN 100. The FirePOWER managed device bridges VLAN 100 to VLAN 101 and allows the two devices to communicate directly with one another. The connection to the FirePOWER device is a single 802.1q trunk.
Frames arriving on VLAN 100 will be processed and egress with a VLAN tag of 101. This configuration is similar to a Continue reading
Gigabit Passive Optical Network (GPON) is an interesting alternative to traditional Ethernet in situations where Ethernet might be difficult or expensive to deploy. Network engineers Andy Burridge and Wallace Chase join us to talk about exactly what GPON is, potential use cases for the technology, and network design challenges.

Giddy up, y'all -- It's roundup time!

Our global expansion continues in Bucharest, Romania, the 6th largest city in the European Union* following London, Berlin, Madrid, Rome, and Paris (nearly all of which feature a CloudFlare PoP!). From Bucharest, our latest data center will serve all 11 million Romanian Internet users, as well as users throughout the Balkans and Eastern Europe.
Romania is geographically situated between Bulgaria, Hungary, Moldova, Serbia, and Ukraine, making it an ideal destination to attract additional Internet traffic throughout much of Eastern Europe. Of course, geographic reality is rarely a mirror of Internet reality. Adding a new point of presence doesn't automatically mean that traffic from surrounding areas (or even traffic in the very same country) will route to that particular data center. This entirely depends on the interconnection of International carriers with local Internet service providers (ISPs) and large networks like CloudFlare.
It is for this precise reason that we place even more emphasis on our interconnection within a particular PoP as opposed to the absolute number of dots we add to our network map. Of course, the combination of the two (expanding wide and deep) is even better, and is why CloudFlare is blazing fast Continue reading
This week, we announced today an exclusive distribution agreement with one of the largest and most innovative distributors in the industry, Arrow Electronics. Under this agreement, Arrow’s Enterprise Computing Business will become the sole distributor of our next-generation networking products and solutions for scale-out applications, agile datacenters and distributed cloud environments. This agreement represents a joint vision that a new generation of Third Platform applications (IoT, Big Data, social, mobile and distributed apps) demand a new software-defined infrastructure to meet the demands for scale-out, virtualized computing. If you’re interested in learning more about our partnership with Arrow, take a look at the CRN Exclusive article on this announcement.

eWEEK: Enterprise Cloud Economy Booming, Driven by Big Data
By Nathan Eddy
The SteelBrick report analyzes how enterprise companies are selling to customers and also examines B2B selling trends compared to this time last year. The market for enterprise technology products is booming, with 72 percent of high-technology providers reporting growth in sales quote volumes, and 42 percent reporting accelerating sales cycles, according to a report from SteelBrick. The report analyzes Continue reading

Free booklet from Ixia describes detailed methodologies to verify SDN & OpenFlow functionality and performance so your network performs at the highest level.
Have you every thought that you knew a topic pretty well but then someone uses terminology that you aren’t used to? People that use Cisco a lot or live outside the MEF world use another terminology than people that are working on MEF certified networks. Even if we both know the concepts, if we don’t speak a common language it will be difficult to communicate and to the the right end result.
When I took the CCDE written at Cisco Live, some of the QoS related material felt a bit off to me. I feel quite confident with QoS so this took me by surprise. My theory is that some of the material was written by someone coming from another background and uses some wording that just felt a bit off to me. I thought that I would read through some of the MEF material to broaden my QoS horizon and see what other terms are being used. At the very least I will have learned something new.
If we start with the basics, we have flows in our networks and these flows have different needs regarding delay, jitter and packet loss. I will write different terms and I will Continue reading
