Remote Sites
by nanog1＠roadrunner.com 29 Jan '16

29 Jan '16

For those of you in an enterprise setting who have remote or satellite locations, how do you have your network access set up? In the past a hub/spoke type model was fairly prevalent. In theory, gives you some extra control and a more consolidated location to deploy infrastructure at (security and monitoring tools mainly), but introduces greater impact when there are outages as well as a latency penalty. I like having an Internet egress point at most of my sites in addition to an MPLS for voice and inter-site communications, but this can complicate monitoring as it's tough to justify spending $$ to install security equipment at every location. Perhaps could rely on a layered service offering from an ISP? Interested to hear what others are doing. Thanks!

Long shot, but if anyone from Twitch could poke me offlist for a few questions regarding it's policy with multiple streamers per IP address (if it's even something we need to consider) We are running a large-ish LAN event and are slightly worried about that. Thanks!

BCM SOC based IPTV STBs
by Jason Lixfeld 28 Jan '16

28 Jan '16

Howdy, What are folks using for BCM SOC (7424 gen, or newer) based IPTV STBs?[1] I’m looking for something pretty simple - HDMI, S/PDIF (optical and 1/8” digital coax) and an Ethernet port is all I’m really interested in. No RCA audio, component video or Wifi. Nice and simple. If GreenPeak RF4CE were baked in, that’d be cool too. Informir and Airties have some interesting stuff, but I’m curious as to what other are using. Thanks in advance. [1] I’m assuming that *IP*TV based discussion is considered relevant conversation? If not, forgive the intrusion, but I’d welcome any pointers on where one might go to discuss this sort of thing if this is considered off-topic.

Re: Equipment Supporting 2.5gbps and 5gbps
by Randy Carpenter 28 Jan '16

I wouldn't say that used or grey market really count as viable options. If we count that, I can get 1GbE for free. The reality is that for a unit that is supported (both software releases and warranty) properly for deployment in mission critical situations, 10GbE costs ~10x 1GbE. While the options you mention have their place, I would not say that any of them are "supported properly" The ubiquiti unit would be very interesting to see, but the lack of support structure would steer me away for anything mission critical. Might be great for test-bed or home use, though. Back on the original topic, I could certainly see a potential for 2.5 or 5 GbE (even optical) if the pricing was better than 10GbE. My guess is that by the time 2.5/5 is really available, 10GbE will be enough more affordable to skip over the 2.5/5 stuff. thanks, -Randy ----- On Jan 28, 2016, at 1:38 PM, Josh Reynolds josh(a)kyneticwifi.com wrote: > EX4500 runs me about $3200-3600 on the gray market, with 2 AC power > supplies and licensing for MPLS. > > Working SFP+ optics from fiberstore.com from $6 on up. > > Also Quanta BMS T3048-LY8 w/ Cumulus Linux, between $3,800-$4,500. > > Ubiquiti is also working on releasing a 12 port SFP+ with 4x10GBaseT, > pricing will be very low. > > It's out there, you just have to look for it. > > On Thu, Jan 28, 2016 at 12:29 PM, Randy Carpenter <rcarpen(a)network1.net> wrote: >> >> I'd love to know what model Juniper you are getting for $102 per 10GbE port and >> where you are getting it.

The context here is doing less than 10G to support old cat5/6 installations. I didn't mention Twinax as if you could use that you'd not need a 2.5 or 5g standard nor have a problem with recent servers coming with 10GbaseT instead of sfp+ when all your previous ones are connected to a SFP+ only switch with fibre or twinax cables. brandon
