Collection of useful, relevant or just fun places on the Internets for 7th March 2014 and a bit commentary about what I’ve found interesting about them:
The Definitive Guide to NSX Gateway Uses Cases – J-Net Community – I missed this earlier but it’s a good summary on NSX use cases from the launch.
Juniper is an NSX development partner and will be talking about NSX support across different products in our portfolio. One term that you’ll see a lot is “NSX Gateway”. For Juniper, this shows up in our routers and switches that will deliver capabilities across two categories: NSX L2 gateway services and VXLAN routing. What makes this notable is the level of flexibility users can enjoy as they implement and migrate to their NSX environment. Lets examine these capabilities, and where we see each potentially being used:
draft-loreto-httpbis-trusted-proxy20-01 – This IETF RFC is a total breach of security and privacy. It should never have gotten this far and I hope that it never makes it to standard.
This document describes two alternative methods for an user-agent to
automatically discover and for an user to provide consent for a
Trusted Proxy to be securely involved when he or she is requesting an
HTTP URI resource over HTTP2 with TLS. The consent is supposed to be
per network access. The draft also describes the role of the Trusted
Proxy in helping the user to fetch HTTP URIs resource when the user
has provided consent to the Trusted Proxy to be involved.
No one, ever, should be able to intercept my HTTP/2 session whether I give my permission or not. Using permission simply creates security vector for hacking this creating vulnerabilities.
Nicira: The Last Billion-Dollar SDN Acquisition? – InformationWeek – Andrew Conry-Murray (who has the longest name in networking) writes a reasonable and well though out post on which startups might survive the growth phase in SDN and be acquired.
This isn’t to say we won’t see more SDN acquisitions, or that startups aren’t doing interesting things. There are so many elements necessary to realize a programmable, scalable, application-aware architecture that incumbents are likely to dip into the startup market to round out a portfolio and/or remove a piece that might be strategically valuable to a competitor.
Interpacket gap – Wikipedia, the free encyclopedia – Wikipedia :
Ethernet devices must allow a minimum idle period between transmission of Ethernet packets known as the interpacket gap (IPG), interframe spacing, or interframe gap (IFG). A brief recovery time between packets allows devices to prepare for reception of the next packet. The standard minimum interpacket gap is 96 bit times (the time it takes to transmit 96 bits of raw data on the medium), which is 9.6 µs for 10 Mbit/s Ethernet, 0.96 µs for 100 Mbit/s (Fast) Ethernet, 96 ns for 1 Gbit/s (Gigabit) Ethernet, 9.6 ns for 10 Gigabit Ethernet and .96/3.8 ns for 100/40 Gigabit Ethernet, respectively.
9.6 ns at 10 Gigabit. That’s not very long.
Brocade Hires Kevin Woods, Cisco onePK Expert – | SDNCentral – Why is Cisco & juniper losing so many of their top SDN people. Here is another senior figure changing employers.
He won’t specify why he left Cisco, but he’s sure happy to explain why he’s joining Brocade.
“A lot of the established companies, especially the big ones, are initially schizophrenic about SDN, and Brocade doesn’t suffer from that,” he says. (As we’ve said before, Brocade thinks of itself as the one who knocks.) “These guys are really committed to SDN. You see it by the hiring that they’ve been doing and the team that they’ve been building.”
That team includes David Meyer, who heads the technical steering committe for the OpenDaylight Project, and recent additions Thomas Nadeau and Benson Schliesser from Juniper.
Brocade has built a a team of high profile people committed to open source and “open-ness”. This looks like a growth strategy for the Ethernet product portfolio to move into a segment that others are ignoring.
