XGS-PON & "Dedicated" Service
by Neader, Brent 25 Oct '23

25 Oct '23

Hello! Interested in getting the larger community's thought on this. The primary question being does XGS-PON have a place in providing a dedicated enterprise level service (at least sold as one) in the marketplace? Delivered via a residential (per the data sheet description) CPE, Nokia XS-010X-Q for a 1gb/1gb dedicated symmetrical service. Background, ive dealt with 30+ providers over the last 18 years, primarily last mile based. Typically we seek out an Enterprise/Dedicated service, with an SLA, typically delivered via DWDM, CWDM, or AE, or equivalent. We have also had a site or two delivered via a PON variant, typically with less of an SLA, typically maybe half to quarter of the price of a dedicated service. Price & SLA sets the expectation of the service, CPE provided, underlying technology, etc. Dealing with a large over-builder right now who has an "elite" enterprise product (highest of 3 tiers) advertised as the following. - 100% dedicated bandwidth so you never have to compete for speed - Mission Critical Reliability with 99.999% guaranteed uptime - Financially backed SLA with the most stringent performance objectives - Enterprise-level customer service and technical support Now I understand with XGS, you can have various QOS in place (WRR/SP, etc), but inherently there are still shared splits involved, that just aren't a thing in other truly dedicated technologies. Expectations were set with the provider's sales team around what was to be delivered and how it was to be delivered that seemingly haven't been met by the product and service team. That aside, from an SP perspective, is it capable to wrap enough layers around service to be "dedicated" even when delivered via a conflicting underlying technology? Or could that be considered disingenuous for those that want to know and understand the difference? Im hoping the service itself and support team make up for the difference, but obviously a little concerned. Thanks!

Acceptance of RPKI unknown in ROV
by Owen DeLong 25 Oct '23

25 Oct '23

A question for network operators out there that implement ROV… Is anyone rejecting RPKI unknown routes at this time? I know that it’s popular to reject RPKI invalid (a ROA exists, but doesn’t match the route), but I’m wondering if anyone is currently or has any plans to start rejecting routes which don’t have a matching ROA at all? Thanks, Owen

Arelion/Telia AS1299 issues?
by David Hubbard 25 Oct '23

25 Oct '23

Hey all, anyone aware of issues with Arelion this morning? We have a bunch of end users on at least Cox and Cogeco who are having serious issues with service access, and the problem appears to be on the return path where it traverses Arelion. Source net is Lumen/L3 3356 but loss/latency doesn’t appear to creep up until already within Arelion’s network. Imperva mentioned outage/degradation due to a national ISP issue too, so I suspect it’s affecting more than just certain peerings. Thanks, David

RingCentral STUN Engineer?
by Stephen M 24 Oct '23

24 Oct '23

Anyone with abilities to view traffic for the STUN servers able to message me off list? I have been going back and forth a couple of weeks now doing PCAPs with not only RingCentral but with Palo Alto on the phone as well showing there is no return traffic coming from the RC side on call initiations and reviewing our configurations continually showing the traffic is allowed on our side. We created explicit in and out rules to define all traffic and no change. I'm stuck in tier 3 (they have been good though) and they are timid to escalate up to the STUN engineers to verify but I can't keep doing the same 'its not us' test with them when it is work impacting. Thanks in advance!

Low to Mid Range DWDM Platforms
by Mike Hammett 23 Oct '23

23 Oct '23

I've been using various forms of passive WDM for years. I have a couple different projects on my plate that require me to look at the next level of platform. In some projects, I'll be looking for needing to have someone long distances of glass without any electronics. Some spans could be over 60 miles. In some projects, I'll need to transport multiple 100-gig waves. What is the landscape like between basic passive and something like a 30 terabit Ciena? I know of multiple vendors in that space, but I like to learn more about what features I need and what features I don't need from somewhere other than the vendor's mouth. Obviously, the most reliability at the least cost as well. Thanks. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com

BGP hijack?
by Hank Nussbacher 23 Oct '23

23 Oct '23

We just had every single prefix in AS378 start being announced by AS2027. Every announcement by AS2027 is failing RPKI yet being propagated a bit. Is this yet another misbehaving device or an actual attack? Thanks, Hank
