Cisco NetFlow kit can be borked with a bad packet
Thursday, 02 March 2017 14:02

Cisco has disclosed a denial-of-service bug in its NetFlow Generation appliances that remote attackers can attack with a bad packet.

NetFlow Generation kit is used to generate, capture and export network flows for billing, service delivery, and security analysis.

Cisco's advisory warns there's a bug in input validation in its Stream Control Transmission Protocol (SCTP) implementation.

If an attacker sends SCTP packets to a network monitored by a NetFlow Generation Appliance, the device can hang or reboot (the advisory notes that it's not triggered by sending the attack packet directly to the appliance).

The issue affects NGA 3140, 3240 and

Brocade SAN sales butchered by hyper-converged upstarts
Saturday, 25 February 2017 05:44

It was a double whammy. Brocade saw hyper-converged infrastructure eat into its SAN networking sales as Broadcom acquisition-caused uncertainty drove IP Networking sales downwards too.

Revenues were $581m in Brocade’s first fiscal 2017 quarter , up by a sliver from the $574m reported a year ago but down 12 per cent from the final FY2016 quarter.

GAAP profits collapsed to a $6m loss – they were $94m a year ago and $67m a quarter ago. What screwed things up?

Brocade says both SAN and IP revenues went down. In the SAN (Fibre Channel) area, product revenue of $307m was down

Friday, 24 February 2017 16:58

Mobile World Congress kicks off next week in Barcelona and, as ever, is two shows in one. Gadget-lovers get to go “squee!” about new handsets and the fun they'll have with them. And in the fun and important part of the conference, telco wonks discuss the plumbing that makes the “squee!” possible.

And this year the fun and important part of the conference looks like having a lot to say about Edge computing, fog computing, software-defined networking and network function virtualization.

It's a good time for the show to consider those matters, because serious momentum is gathering around standards and

London Internet Exchange members vote no to constitution tweak
Thursday, 23 February 2017 00:02

Members of LINX, the London Internet Exchange – the UK's largest net peering point – have rejected proposals that would reshape the company’s constitution and could block members from being consulted about government tapping instructions.

Directors of the company had urged the 740 members of LINX, mostly Internet providers from overseas, to
