Are there inexpensive DWDM products?
by LF OD 04 Nov '17

04 Nov '17

We have several buildings and a couple data centers spread around the city and interconnected via dark fiber. It's a very simple setup - no ROADM, no real ring, no extended layer-2 or layer-3 via the optical gear. Pretty much we just mux/demux a channel for each building so that each building sees the two data centers directly even though the fiber span may wind through a couple buildings along the way. In some cases, the distance is short enough to use colored optics in the network gear, but mostly the distances are just long enough to warrant transponder cards. All that being said, a lot of the gear is approaching end of life (support in some cases). I'm not an optical guru but I can muddle my way through with Cisco ONS and I'm aware that Ciena and Fujitsu also have similar products. We really don't have budget for a large optical refresh effort. However, we've saved some money here and there in the routing/switching arena by leveraging Arista and even Cumulus. I'm wondering if there are smaller players in the optical arena that have a good quality/price value? Again, we don't need sophisticated features... we primarily have 2-to-4 1Gb and 10Gb ports required per site, then we mux those onto a wavelength and extend it to the two data centers. Most buildings are set up the same way, each on a different wavelength so the don't even see each other... only the data centers. If you guys know of any optical gear that you can vouch for (and which costs less than a small house), we would greatly appreciate it. Thanks LFOD

Calgary <-> Toronto 100% Canadian Fibre Resiliency on failover
by Jacques Latour 02 Nov '17

02 Nov '17

Hi, Does anyone know if there's fibre resiliency between Calgary and Toronto over the Great lakes, I thinking redundancy could be achieved by using two paths one following the railroad and the other following the Trans-Canadian highway. Does anyone know if there is fibre following the Trans-Canadian highway and who owns it? Is this achievable? Thanks, Jacques CTO, CIRA

What's the point of prepend communities?
by Jason Lixfeld 01 Nov '17

01 Nov '17

Hi, Of all the ISPs that I am familiar with that have a BGP community structure usable by their peering partners and/or downstream customers, among other things, they allow the customer to signal the ISP to prepend their own AS to the as-path of a particular prefix announcement. What functionality does a provider prepend support that is otherwise lost in the absence of such a feature, but all the while, the customer would be able to prepend their own AS to the same prefix announcement anyway? Is this a relic from before ISPs allowed for local preference adjustment, or is there actually a use case for this? Thanks!

Physical Layer fiber Software Tools?
by Craig 30 Oct '17

30 Oct '17

I am hoping someone could help me out with some suggestions for any software that is available, for individuals that are doing physical layer wiring in a data center? The idea is the technician is performing the fiber runs from say RACK 111 router AAA port 1/1/1 to RACK 222 router BBB port 1/1/1 The fiber is connected to a LIU in the TOP of the rack, and then will require various cross connects to get to the other rack. If the various racks and LIU's are pre-populated into the software, and then a standard for the fiber labels is also installed ahead of time into the software tool. The technician has a tablet or laptop to enter the data, and then it will print out a cable label based on the info entered into the tool. The back-end data base is updated for each fiber so the complete path is known. This way its a one step process. Maybe my description of this is readily available or have other companies developed a custom software tool to achieve this? Appreciate any feedback.

Ping a Comcast Business DNS Admin?
by Aaron C. de Bruyn 27 Oct '17

27 Oct '17

I'm hoping a Comcast engineer can clear something up for me: If I recall correctly siteprotect.com is used by Comcast Business hosting. We have a mutual customer who has their domain NS pointed at ADNS.CS.SITEPROTECT.COM and BDNS.CS.SITEPROTECT.COM and those servers resolve their domain properly, but as of two weeks ago I no longer have the option to edit the customer's zone when signing in to businessclass.comcast.net. Phone reps have said "we don't manage you DNS" or "NetSol is their registrar", or even "Hmm...you're right, there's something wrong, but I don't know what's going on". On top of all of that, Comcast told this mutual customer to update their DNS records because they are being migrated to Office 365. But the customer can't access it to edit it. Feel free to contact me off-list for the domain and customer details. -A
