HP and Cisco Take Different Paths To SDN
February 03, 2012 11:00 AM
News that Cisco Systems may release proprietary networking products implementing software-defined networking (SDN) technology, but not necessarily based on the emerging OpenFlow protocol, has executives at rival HP complaining about another Cisco vendor lock-in play. During a news event at HP Thursday, at which the company announced OpenFlow capability available for 16 HP networking product lines, executives were asked to comment on a news report from the Cisco Live event going on this week in London.Why I Like Juniper's QFabric (And A Mea Culpa)
February 02, 2012 09:00 AM
While I was visiting Juniper in early December, I got a chance to sit down with the QFabric folks to discuss some of issues with QFabric and what I saw as a proprietary—with all the badness that word implies—product set in search of a reason. While QFabric is proprietary because of how the components are interconnected, I came away with the impression that the overall design and capacity looks extremely powerful. I think the upsides of the QFabric product set far outweigh the downsides. Give a month's time between visiting Juniper and now, I'd say that all my ballyhoo about being proprietary was a non-issue. My bad.As IT Demands More Of Networks, Expect HP-Cisco Rivalry To Intensify
January 03, 2012 08:00 AM
Across IT, many observers have identified three broad trends going forward: mobility, cloud computing and the consumerization of IT. When it comes to networking, these trends are expected to drive demand for more bandwidth capacity and, increasingly, wireless network architecture. In addition, 2012 is expected to see a continuation of the intense rivalry between industry leaders Cisco Systems and HP, as the latter tries to chip away market share from the former.2011 Was An Awesome Year For Networking
December 28, 2011 08:00 AM
After about eight or nine years of networking innovation stagnation, the number of new innovations starting in 2010 and exploding in 2011 is astounding. Speed and feeds are increasing, but the exciting work in 2011 occurred in new technologies to support initiatives such as cloud computing, storage and data convergence, as well as migrating to IPv6. Here are the highlights.All I Want For Christmas Is 10Gbase-T
December 23, 2011 10:20 AM
Dear Santa: The best present you, and the networking industry, could give me is general availability of 10GBase-T across switches and NIC/CNAs. Once I can just order my 10gig network gear with 10Gbase-T, I can stop worrying about how to pay for optical transceivers at $350 to $1,200 a pop, as well as about the never-ending compatibility problems with both optics and twin-ax direct connect cables.Networking APIs Should Be A Critical Feature
December 19, 2011 07:00 AM
When you are looking at your next network equipment refresh, be sure to take a long, deep, look at the APIs the vendors are exporting and importing. Integration features should be near the top of your must-have feature list.Roll Your Own Interference Signatures With AirMagnet
December 16, 2011 02:13 PM
As anyone who has an understanding of Wi-Fi will tell you, interference is the one threat to the WLAN that you can't really do much to prevent from a configuration standpoint. When interference does show up, accurate classification and remediation can be the key to client success or frustration. Fluke Networks has just freshened up its AirMagnet Spectrum XT analysis tool as a leading weapon in the war on interference.The Cable Conundrum Continues--Vendors Respond
December 15, 2011 10:57 AM
After my initial adventures with 10 Gigabit Ethernet cabling, as recounted in "The 10 Gigabit Ethernet Cable Conundrum," I realized I needed to research this matter further. I put together a few simple questions about 10 Gigabit Ethernet connection technologies and sent them to some leading vendors to see what challenges a system administrator building a multivendor network would face in the real world.The 10 Gigabit Ethernet Cable Conundrum
December 01, 2011 10:59 AM
As we enter the 10 Gigabit Ethernet era in the data center, we're facing some difficulties regarding cables and optics. While I'm happy all the vendors have settled on SFP+, eliminating the nightmare of figuring out if a given device uses XFP, Xenpack or X2 optics to make 10 Gigabit Ethernet affordable, we're going to have to use copper cables for the 10-Mbps or shorter connections within the data center. I just wish that was as easy as grabbing a cable that meets industry standard specs and plugging it in.IPv6 Momentum Takes Huge Swing
November 21, 2011 11:35 AM
A new Infoblox-sponsored IPv6 Census conducted by the Measurement Factory reports a 1,900% increase in the percentage of zones under .com, .net and .org that support IPv6. Only 1.27% of the zones surveyed in 2010 supported the successor to Internet Protocol version 4 (IPv4), compared to today's 25.4%.« Previous Page | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | Next Page »
