Network card with relay in case of power failure
by Dovid Bender 18 Jun '20

18 Jun '20

Hi, I am sorry if this is off topic.I was once demoed a network device that had two interfaces. The traffic would go through the device. If there was a power cut or some other malfunction there would be a relay that would physically bridge the two network interfaces so the traffic would flow as if it was just a network cable. Is anyone aware of such a network card or device? TIA.

Quality of the internet
by Dovid Bender 18 Jun '20

18 Jun '20

Hi, My 9-5 is working for a VoIP provider. When we started in 2006 we had a lot of issues with the quality of the internet in eastern europe and central Asia. It was not rare for us to have to play around with routing to get the quality that we needed. In a review of tickets for the last two years it seems as if we barely do any of that these days. Rarely do we get a quality complaint that comes back to an issue where a carrier or ISP dropping or mangling packets. Has anyone else observed this as well?

Router Suggestions
by Colton Conor 18 Jun '20

18 Jun '20

For around $11,000 right now, you can get a brand new Juniper MX204 router. Alternatively, you can get a used MX240 / MX480 with quad power supplies, redundant quad core RE's, and 2 16X10G MIC cards for around $12,000. My question, is there anything else worth looking at in this price range / port configuration? Open to both new and used options. Looking to take full BGP routes.

I noticed that Mikrotik has added RPKI into their very much beta v7 branch. I would like to ask those of you that know RPKI well to check it out and offer Mikrotik feedback on what they've done right\wrong\broken. Thanks. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com

Hurricane Electric has reached 0 RPKI INVALIDs in our routing table
by Mike Leber 18 Jun '20

18 Jun '20

I'm pleased to announce Hurricane Electric has completed our RPKI INVALID filtering project and we now have 0 RPKI INVALIDs in our routing table. Hurricane Electric has 29021 BGP sessions with 22109 prefix filters with 7191 networks directly and 8239 networks including Internet exchanges. We filter all BGP sessions using prefix filters based on IRR and RPKI. These prefix filters are updated automatically both through a system of daily updates and real time updates to prevent RPKI INVALID routes from being carried in our routing table.

The thought of global MPLS labels scared people and source routing was also evil. So LDP was created to distribute labels hop by hop, while still relying 100% on the IGP to do so. It kind of defies common sense when you look at it now, but there were supposedly good reasons for it back then. > > SR-MPLS on an existing device supporting MPLS forwarding is a control-plane change, meaning almost any device could support SR-MPLS. > > SR is meant to be data plane agnostic, the SID is just an identifier. Most support MPLS, some support IPv6. Fair enough. There's still a whole IGP mess to sort out though, not to mention many years of field experience to bake in. Mark.

Client-side information gathering tool
by Matt Harris 18 Jun '20

18 Jun '20

Hey folks, I was hoping maybe someone could point me in a useful direction here. I'm looking into software tools (ideally, they'd support Windows, Mac, and Linux, though Windows is perhaps the only critical one) that can be sent over to random users with varying (mostly very little) knowledge of how the internet works to gather a bunch of data that they can then provide to us to help identify connectivity issues between the client and a chosen endpoint. IPv4 and IPv6 support are requirements. I've got a lot of clients with VPN connections of varying sorts running on internet connections of often very low quality, and sometimes even in places where reasonable quality doesn't seem to even exist. Right now, when these users complain, this often means my support folks get to walk them through downloading winmtr and running that as well as other command line tools to gather a bunch of other information about their computer, its connection to their LAN, their LAN configuration as best as we can tell, and their connection to the greater internet. This is somewhat cumbersome of a process though. If we could send them something they could click on and then copy/paste out of or otherwise direct the data to us, that would save a fair bit of time and also be a lot less patience-grating on the part of our clients. Any links to potentially useful tools (commercial or free are both fine) would be appreciated. The main goal is getting lots of relevant information to us without having to walk an end-user through lots of steps to do so. The more relevant data, the better.

Mystery CDN
by Clinton Work 17 Jun '20

17 Jun '20

I'm struggling to determine which CDN owns the servers in CenturyLink prefix 8.240.0.0/12. During the Call of Duty Season 4 update on June 11th from 06:00 UTC until 08:30 UTC, we had 240 Gbps of traffic steaming into our network from CenturyLink prefix 8.240.0.0/12. We originally thought it was Akamai, but they swear up and down that the servers don't belong to them. Here are some of the HTTP/HTTPS servers in 8.240.0.0/12: 8.253.151.248 8.251.135.126 8.240.167.126 8.240.228.126 8.240.168.126 8.240.126.254 8.240.191.254 -- Clinton Work Airdrie, AB

IPv4 routes spiking from 10PM EST until 8AM EST
by Drew Weaver 17 Jun '20

17 Jun '20

Has anyone noticed over the last week or so that the IPv4 routes appear to be spiking up temporarily every night from about 10PM EST until about 8AM EST? Is that just someone trying to test flipping over other network's TCAMs? Just wondering.
