Savvius Insight and the use of Elastic
Last week Savvius announced upgraded versions of its Insight network visibility appliances. These have the usual performance and capacity increases you’d expect, and fill a nice gap in the market.
But the bit that was most interesting to me was the use of an on-board Elastic stack, with pre-built Kibana dashboards for visualizing network data, e.g.:
Historically the only way we could realistically create these sorts of dashboards and systems was using Splunk. I’m a big fan of Splunk, but it has a problem: Cost. Especially if you’re trying to analyze large volumes of network data. You might be able to make Splunk pricing work for application data, but network data volumes are often just too large.
Savvius has previously included a Splunk forwarder, to make it easier to get data from their systems into Splunk. But Elastic has reached the point where Splunk is no longer needed. It’s viable for companies like Savvius to ship with a built-in Elastic stack setup.
There’s nothing stopping people centralizing the data either. You can modify the setup on the Insight appliance to send data to a central Elastic setup, and you can copy the Kibana dashboards, and create your own Continue reading

IPv6 Trends, SixXS Sunset and Project Planning
Native IPv6 availability continues to increase, leading to the sunset of SixXS services. But it looks like we don’t like starting any major IPv6 rollouts around Christmas/New Years, but instead start going into production from April onwards.
SixXS Sunset
In March 2017, the SixXS team announced that they are closing down all services in June 2017:
SixXS will be sunset in H1 2017. All services will be turned down on 2017-06-06, after which the SixXS project will be retired. Users will no longer be able to use their IPv6 tunnels or subnets after this date, and are required to obtain IPv6 connectivity elsewhere, primarily with their Internet service provider.
SixXS has provided a free IPv6 tunnel broker service for years, allowing people to get ‘native’ IPv6 connectivity even when their ISP didn’t offer it. A useful service in the early days of IPv6, when ISPs were dragging the chain.
But this is a Good Thing that it is now closing down. It’s closing down because their mission has been achieved, and people no longer require tunnel broker services. IPv6 is now widely available in many countries, and not just from niche ISPs. Mainstream ISPs such as Comcast in Continue reading

Show 340: OpenFlow, Fabrics & Network Virtualization
Todays Weekly Show is a wide-ranging discussion on OpenFlow (and what happened to it), network disaggregation, & network virtualization. Our guest Wes Felter and the Packet Pushers explore the current state of networking and speculate about where the industry is going.

Pockethernet – A Smartphone-Enabled Cable/Link/IP Tester
I saw an advertisement for Pockethernet a few months ago and it looked pretty impressive; €167.23 (~$179 based on xe.com‘s published exchange rates at the time of writing) for a 200 gram rechargeable device offering 10/100/1000 Ethernet and cable testing features such as:
- A cable tester (wiremapping, TDR fault detection, PoE testing, BER and an analog toner)
- Link analyzer (speed, duplex, VLAN tags, CDP/LLDP, traffic detection)
- IP analyzer (DHCP, DNS, HTTP, ICMP ping)
- Report generation
Over all, Pockethernet sounded like something I needed to look into more closely.
Pockethernet
Pockethernet started off with the assistance of a crowdfunding campaign on Indiegogo, raising $185,000 of their $50,000 target. Unusually for an electronic device, Pockethernet is manufactured in Hungary, which was nice to see. Unboxing the Pockethernet I was surprised (but pleased) to discover that the device is packaged in a soft, zipped carry case.
The box also contains a small User Guide, and inside the case is the Pockethernet tester, an adaptor, a short Ethernet cable and a short USB charging cable. There’s also a strip of blue velcro which will be useful to hold the tester in place if needed.
As it turns out, keeping the Pockethernet Continue reading
