Re: CNOC's Part 1 Filing on the 703/704 tariffs Reading the march 8th responses. CNOC has been a bad boy and have purchased wholesale volumes of "#" from Bell for their filing....
quote:
Pursuant to section 39 of the Telecommunications Act, the network details of the three CNOC members that have elected to provide responses to the Commission’s request for information are being filed in confidence with the Commission. The information in question is of a competitively sensitive nature to the three CNOC members.
Tisk Tisk  Even the names of the ISP are converted into Bell Canada's proprietary "#" characters.
Their idea of small: ISP l big enough to have 2 AHSSPIs. (but they needed that to make their point). |

Large Independent ISP
A) The company uses the services of a number of incumbents in order to provide service to its end users. For the purpose of responding to this question, the company is focusing on those incumbents that have adopted the capacity method approved in TRP 2011-703.
Bell Canada: The company interconnects with Bell Canada through 23 1 Gbps AHHSPIs mapped to EAS links according to a 1 to 1 relationship. This arrangement provides the company access to end users encompassed by Bell Aliant’s/Bell Canada’s entire footprint in Ontario and Quebec.
Rogers: The company interconnects to Rogers using 4 10 Gbps links that are mapped into 37 VLANs that connect to a total of 19 POIs. This arrangement provides the company access to end users encompassed by these Rogers POIs.
Cogeco: The company has 1 Gbps # link to one POI in Cogeco’s serving territory. This arrangement provides the company access to end users encompassed by the Cogeco area served by that single POI.
Videotron: The company has 1 Gbps connection to Videotron’s main aggregation POI in Montreal. This arrangement provides the company access to end users encompassed by Videotron’s entire footprint.

Cogeco says it uses ECMP (Equal Cost MultiPath) to distribute upstream traffic amongst the number of links that exist to the ISP and that this provides load balancing as well as automated failover.
Can anyone comment on ECMP ? Wikipedia does not have nice things to say about it.
Anything preventing ISPs from using the same for the downstrieam traffic (from ISP to the cableco) ?
Also, assuming that the lan extensions between the caleco and the ISP are terminated by switches, with ECMP, how would a router know that one of 4 links has gone down ? |

| said by jfmezei:Can anyone comment on ECMP ? Wikipedia does not have nice things to say about it. Cost-based routing is an IP-routing concept where each possible route has a cost associated with it and routers choose paths based on lowest cost. By setting multiple paths to same cost, the router simply picks one for each packet and calls it a day. This is essentially is an IP equivalent of LAGs on Ethernet. The traffic distribution likely uses header hashes like LAG does so each src:dest pair always uses the same path to avoid out-of-order transmissions.
Since this is an IP-based solution, it can only work with TPIA.
said by jfmezei:Anything preventing ISPs from using the same for the downstrieam traffic (from ISP to the cableco) ? If the cableco makes it work one way, there is no reason for it not to work the other way with the same cableco.
For cablecos that hand out connections over MPLS, VLANs or other traffic segregation method, you are out of luck. Cogeco's ECMP can only work for plain-IP interconnect.
said by jfmezei:Also, assuming that the lan extensions between the caleco and the ISP are terminated by switches, with ECMP, how would a router know that one of 4 links has gone down ? In all likelyhood, the switch would advertise route-down, the router would pick that up, look up which routes are affected, drop them and (optionally) start looking for alternate routes.
As for why a "switch" would advertise that a route is down, there is no such thing as a switch-only "switch" in the carrier market, most have a fully functional IP routing core feature set. |

IIRC, there seems to always have been a tit for tat (or neck in neck) counting of Bell AHSSPIs (around DSLR) for TSI & for Acanac (which would now include those of D-Tel too).
So wouldn't the more likely identifier be the single Cogeco POI ? (thinking Chatham), as doesn't Distributel already service from more than one Cogeco POI ?

-The current model with CBB for residential and flat rate for business has created a quagmire.
-Two parties quoting an exchange between KvF and Mr. Rocca, but extracting different meanings from it. |
