IP Dslams
by Nick Edwards 06 Jan '19

06 Jan '19

Howdy, We have a requirement for an aged care facility to provide voice and data, we have the voice worked out, but data, WiFi is out of the question, so are looking for IP-Dslams, preferably a system that is all-in-one, or self contained, as in contains its own BBRAS/LNS/PPP server/Radius, such as has a property managment API, or even just a webpage manager where admin can add in new residents when they arive, or delete when they depart I know these used to be available many years ago, but that vendor has like many vanished, only requirement is for ADSL2+, prefer units with either 48 ports or multiples of (192 etc) and have filtered voice out ports (telco50/rj21 etc) If anyone knows of such units, would appreciate some details on them, brand/model suppliers if known, etc, we can try get out google fu back if we have some steering:) Thank Y'all (resent - original never made it to the list for some gremlin reason)

How common is it for Verizon to deliver "Internet Dedicated Ethernet" over sonet? Ran into a situation where the canoga-perkins nte was uplinked to a Flashwave 4100es in the basement (uplinked by an OC-48). There is in a Verizon ILEC area. Thanks & Regards, Mitchell Lewis mlewis(a)techcompute.net

Re: Changing upstream providers, opinions/thoughts on 123.net and cogent
by Neader, Brent 04 Jan '19

Looks like they already are? https://bgp.he.net/AS14374 Depending on which peer you might be replacing 123.net or cogent with, that could possibly change someone’s opinion. However, at least from past topics on this, given cogent history with peering issues (such as HE.net cake), I think one would certainly want to understand what impact peering/routing quirks would cause them and their ability to work around them before selecting cogent. Given I doubt your international reach is a big deal, and given 123.net is more of a tier2 (https://bgp.he.net/AS12129) with local and regional peering ( https://www.peeringdb.com/net/3899 ), they could be better suited for your traffic patterns and local customers? Also if you are not already interconnected with 123.net from a transport perspective, given their footprint in the state, there could be opportunities for an NNI to expand your reach to help interconnect your customer’s locations (aka customer has a branch office inside and outside your direct footprint and wants ELAN type service). I have looked at them before but never got serious, and thus cannot offer any input on their actual service or support.

I, along with the people in my circle, do not have any experience with these providers and all we are getting is what sales are dishing us. I was hoping some of you here might have experience with these providers and could share your experiences and opinions. Thanks, A

How to choose a transport(terrestrial/subsea)
by Mehmet Akcin 04 Jan '19

04 Jan '19

Thank you everyone incredible amounts of responses for my how to choose a transit provider smail earlier. How do you choose transport & backbone? Looking at key aspects like route information, diversity, aerial vs under ground fiber, age of fiber, outage history, length, but what else? I will get both transport and transit as two seperate blogs. I will also submit as a nanog paper for the meeting after next, or maybe next? I am probably too late by now. Thank you for all your help. I will add your names to the thank you line ;-) -- Mehmet +1-424-298-1903

Cleveland/Cincinnati Co-location
by Mitchell Lewis 03 Jan '19

03 Jan '19

Good Evening All, I am working on project that may involve building points of presence in Cleveland & Cincinnati. Any suggestions as to which colocation facility in each city to build in? The prime factor of consideration for this project is access to waves to places like Chicago, New York & Ashburn. It would be nice to have multiple wave provider options to choose from. I have been looking at Cyrus One-7thStreet in Cincinnati & Databank in Cleveland. Thanks & Regards, Mitchell Lewis 203-816-0371<tel:+12038160371>

does emergency (911) dispatch uses IP ?
by Mankamana Mishra (mankamis) 02 Jan '19

02 Jan '19

Guys, While reading CL network down impacting 911 services, was trying to get more information about how does this network looks like. From end user to center, I guess VOIP is used. Wondering what is the communication method from Emergency service center to end units (Police, Fire or any other services). Do they also use IP ? or its Still Radio only ? if it is IP, do they use Unicast or multicast or broadcast ? Tried googling, but did not get much information. Any insight would be appreciated. Thanks Mankamana

CenturyLink RCA?
by Saku Ytti 02 Jan '19

02 Jan '19

Apologies for the URL, I do not know official source and I do not share the URLs sentiment. https://fuckingcenturylink.com/ Can someone translate this to IP engineer? What did actually happen? >From my own history, I rarely recognise the problem I fixed from reading the public RCA. I hope CenturyLink will do better. Best guess so far that I've heard is a) CenturyLink runs global L2 DCN/OOB b) there was HW fault which caused L2 loop (perhaps HW dropped BPDU, I've had this failure mode) c) DCN had direct access to control-plane, and L2 congested control-plane resources causing it to deprovision waves Now of course this is entirely speculation, but intended to show what type of explanation is acceptable and can be used to fix things. Hopefully CenturyLink does come out with IP-engineering readable explanation, so that we may use it as leverage to support work in our own domains to remove such risks. a) do not run L2 DCN/OOB b) do not connect MGMT ETH (it is unprotected access to control-plane, it cannot be protected by CoPP/lo0 filter/LPTS ec) c) do add in your RFP scoring item for proper OOB port (Like Cisco CMP) d) do fail optical network up -- ++ytti

Auto-configuring IPv6 transition mechanisms on customer devices
by Brandon Martin 02 Jan '19

02 Jan '19

Are there any (draft, standard, or otherwise) defined mechanisms for indicating to customer-provided devices that they should configure IPv6 to IPv4 transition mechanisms such as MAP, 4rd, 464XLAT, etc. and providing the configuration details thereof? I'm not aware of any. It seems like this is something that, if defined, would make deployment of such mechanisms a lot easier even if SPs provide the customer edge router that implements said mechanisms. I guess they'd probably be implemented as extensions to DHCPv6 or similar or embedded in RAs (the latter seems ugly). -- Brandon Martin
