  Tibco And LogLogic: An Interesting and Revealing Acquisition by Jon Oltsik

  Over the past few years, a number of independent Security Information and Event Management (SIEM) vendors were acquired by bigger players.  In late 2010, HP scooped up market leader ArcSight for $1.5 billion.  Last year, McAfee purchased Nitro Security while IBM acquired Q1 Labs.In each of these deals, large vendors were using these acquisitions to bolster existing security offerings, replace legacy SIEM platforms, or filling holes in their portfolios to grow their security...

  The Four Lies of Networking by Dave Greenfield

  Big Data and networking in general are all about numbers and statistics. We talk about our Petabytes of data, the number of packets per second and the Mbytes replicated in an hour. We want to know about the uptime percentages of our services and the time to repair on our circuits. We’re sold on loss ratios and round trip times.And like statistics and their “Lies, damned lies,” as Mark Twain put it, networking has its own set of fallacies and half truths we’ve all run up against. Here are the...

  Q4 challenges not a downturn, Cisco CEO says by Jim Duffy

  After marked improvement in its business following the wrenching restructuring and "reinvention" Cisco's gone though over the past year, the company - and perhaps the industry - are not out of the woods yet.Cisco's current quarter, the fourth in its 2012 fiscal year, is likely to come in well below Wall Street expectations due to ongoing economic challenges - particularly in Europe - and conservatism in enterprise IT spending. Cisco's Q3 came in as planned last week, but the company's forecast...

  Warrior keynote on Cisco COPE by Jim Duffy

  Implementing security policies into the network based on identity and other application and user awareness parameters will drive network programmability, with network-based APIs and customer-specific algorithms, Cisco CTO Padmasree Warrior said last week during her Interop keynote address. That's the same keynote where Warrior briefly discussed the Cisco Open Programmable Environment (COPE), the company's SDN architecture that it will apparently discuss in more detail at next month's CiscoLive...

  Finding your TV shows on the Internet by Steven Vaughan-Nichols

  It seems to me some days like the media companies want their own Internet TV subsidiaries to fail. Take, for example, the simple task of finding the show you want. DVRs manage it, TV Guide managed it when the only way we got to watch TV was by using rabbit ears. But finding the shows you want from Hulu Plus, iTunes, or Netflix can be a major pain in the rump. Oh sure, each of them makes it easy on the Web to see what they offer, but let's say you want to find a TV show and you don't know which...

  Cisco's not on board, but is Shortest Path Bridging winning? by Jim Duffy

  Is Shortest Path Bridging (SPB) winning the data center fabric standards battle? One could have walked away from Interop 2012 with that impression, given the level of interest in it during a conference session and the production implementations that were discussed at the show.SPB is IEEE 802.1aq and is based on the same MAC-in-MAC technique used in IEEE 802.1ah,  Provider Backbone Bridging. SPB uses a link state routing protocol to allow switches to learn the shortest paths through an...

  Next-generation Enterprise WANs

  WAN Virtualization is the next-generation complement to WAN Optimization by Andy Gottlieb

  Fellow Network World blogger Zeus Kerravala, wrote an interesting post in his Network World blog last month about the need for a different type of WAN Optimization from branch to the cloud. He also wrote another piece here about the need for “next-generation WAN Optimization.”While we’ll get into the details through the course of this column, let me start with the punch line: WAN Virtualization is the next-generation complement to WAN Optimization that Zeus is looking for,...

  Best of Interop Awards called out for product no-show by Larry Chaffin

  This blog below was sent to me in email. While I was not going to write about it, I am glad someone else called out the awards. The Best of Interop Awards are a great thing in Las Vegas and companies revel in winning or getting just nominated. But there are some problems with them that need to be fixed. If you have a product, get nominated and win, you should have the product at Interop for people to see. While this is in the rules it has never been pushed on vendors, as was the case this year...

  Putting Realism Into Your Network

  Are they a contender or pretender? Can Huawei survive in North America? by Larry Chaffin

   As everyone knows Huawei tried to make a big splash at Interop with a booth to rival Cisco's booth, matter of fact they were side by side on the Interop floor. But the question was how did they do and will they make it in North America? I took many trips to the booth and watched many presentations, let just say they have a long way to go. On one of my trips I had the chance to talk to Thomas Keenan Senior Marketing Manager. While asking questions about the products line and acquiring...

  All Things Interop Part 1 by Jon Oltsik

  I'm here in Las Vegas wrapping up Interop 2012.  I now understand why Hunter S. Thompson binged on alcohol and narcotics when visiting this town -- you need these substances to create the illusion that this town is the least bit palatable. Aside from the Sin City aspect, Interop was eventful and the industry seems to be in good shape.  A few thoughts:1.  Cisco SDN.  Cisco CTO Padmasree Warrior stunned the audience when she mentioned in her keynote that Cisco has been...
