Networks are converging at an unprecedented pace – a fact which is widely known and accepted in today’s hyper-growth and incredibly competitive global business environments. On top of that, every network flavor (fixed, wireless, cloud, enterprise…) must manage according to insanely accelerated cycles for updates, improvements, and advancements in their networks to support that complexity. […]

Many network administrators still manage networks within their local data centers, but they’re increasingly troubleshooting in the cloud as businesses deploy more cloud workloads. According to RightScale’s latest “State of the Cloud” survey, 85 percent of enterprises have a multi-cloud strategy. Businesses run an average of 41 percent of workloads in public clouds and 38 […]

With more organizations exploring or implementing Cisco ACI, some users question the need for packet capture. However, there are several use cases where it is critical to leverage packet data and packet-based analytics, especially for larger enterprise and data centers. Application centric infrastructure, or ACI is used to more efficiently and effectively roll out and […]

Part 3 of the Evolution of Fronthaul Networks (read Part 1: Intro to Fronthaul and Part 2: Fiber Deployment in Wireless) In parts 1 and 2, I described the overall radio access network architecture and best practices for deployment at physical layer which is primarily fiber for the links between the base band unit (BBU) […]

Cyber investigators reveal how harvesting the right data can help solve network security issues and provide legal peace of mind. While much of the world is harvesting crops in preparation for the coming winter, network teams are, as usual, harvesting network data. As anyone who captures packets knows, sometimes these payloads contain surprises. As you […]

 This is a re-post of an article in Gazettabyte, © Roy Rubenstein 2017 The race is on to deliver 400-gigabit optical interfaces in time for the next-generation of data centre switches expected in late 2018. The industry largely agrees that a four-wavelength 400-gigabit optical interface is most desirable yet alternative designs are also being developed. Optical […]

Part 2 of the Evolution of Fronthaul Networks (read Part 1: Intro to Fronthaul and Part 3: CPRI ) As we learned in part 1, fiber deployment permits the placement of RRH’s closer to the antenna. Also known as light radio, this RRH placement has significantly improved the energy efficiency of cellular networks as the […]

Packet Pioneer Chris Greer reveals his own Wireshark nightmare while dealing with trace files in the popular analyzer. “I’m a big user of Wireshark,” says Chris Greer, network and application analyst and founder of Packet Pioneer. “I own and operate an independent consulting company. What I do is I sit on the beach in Costa […]
