Last week Tony Rybczynski put up a blog on the Cisco Nexus switch entitled "The Nexus is no Lexus". Tony got a lot of comments, including a link that was from the Network World Cisco blog. This was responded to on the Network World Cisco blog by Doug Gourley of Cisco. In his response Doug states; "Certainly companies that have consistently failed to innovate and deliver in the networking segment, that have married their own R&D capabilities so tightly to the merchant silicon vendors that they have no capability for competitive differentiation."

Cisco is well known for a profound inability to innovate internally and a penchant for acquisition as ...

Cisco VSS….too little, too late?

As I discussed in a previous set of blog postings, delivering redundancy is a critical path to assuring overall system availability. For a number of years, Nortel has deployed a patented implementation called Split Multi Link Trunking (SMLT) that uses the IEEE 802 standard in a configuration that is active-active with incredibly low switchover time. When compared with traditional techniques, such as spanning tree or routing, this technique has been judged vastly superior by both our customers and by independent testing organizations such as the Tolly Group. Nortel has deployed this technology for over six years to deliver effective Switch Clustering in a number of Ethernet Switching platforms. ...
