Interrogatories to Cogeco Cable Inc., Quebecor Media Inc., on behalf of its affiliate Videotron Ltd., Rogers Communications and Shaw Communications Inc.
(collectively, the cable carriers)
1. Provide the company’s current end-user demand for static IP addresses associated with the company’s retail services.
2. For the current TPIA service, describe the sequence of steps by which an IP address is associated with an end-user’s cable modem, beginning at the time that the end-user turns on the cable modem, and ending at the time the cable modem has been configured with an IP address, ready for use by an end-user.
3. In its submission dated 27 October 2010, Vaxination Informatique (Vaxination) proposed three approaches for providing end-users of the TPIA service with fixed IP addresses as summarized below:
i. Approach One: Dynamic host configuration protocol (DHCP)-based dynamic allocation of IP addresses utilizing two groups of addresses per ISP per CMTS, with one group having a short lease length and the other group with long lease length; the ISP’s cable modems would be configured to receive parameters from one of the two groups (see paragraphs 15 to 17 of Vaxination’s submission for a detailed explanation)
ii. Approach Two: IP address allocation utilizing two groups of addresses per ISP per CMTS, with one group of addresses assigned on a dynamic basis and the second group assigned on a static basis; the ISP would advise the cable carrier to set up an end-user’s modem with static assignment to a selected IP address ( see paragraphs 18 and 19 of Vaxination’s submission for a detailed explanation)
iii. Approach Three: The ISP sets up its end customer as if he were dynamic. The ISP gives the end customer an IP address and the customer creates a static configuration with the fixed IP address and does not use DHCP. The ISP provides the customer with all parameters and advises him of any changes (see paragraph 20 to 22 of Vaxination’s submission for a detailed explanation)
For each of the three above approaches, each company is to provide its responses to the following questions:
a) Explain whether the company currently makes use of this approach (or a similar approach) for providing fixed IP addresses to some end-users of its retail internet access service? If so, describe the approach, and explain whether the proposed approach would be an acceptable approach for providing fixed IP addresses to end-users of the wholesale TPIA service, with supporting rationale.
b) If in response to part a) the company indicates that it does not currently make use of this approach (or a similar approach) for providing fixed IP addresses, explain whether the approach for providing fixed IP addresses is technically feasible to implement. If so, describe the modifications required, identifying the resources and activities required; further, provide an estimate of the costs to implement the proposed approach for the wholesale TPIA service; and comment on the economic feasibility of implementing the approach.
c) If in response to part b), the company indicates that the proposed approach is not technically feasible, explain why not.
4. With reference to paragraph 15 of the cable carriers’ reply comments, the cable carriers submitted that “over the top” technologies such as VLANs and Point-to-Point Protocol over Ethernet (PPPoE) were potential alternatives for providing static IP addresses that ISPs could deploy themselves. Describe how ISPs that make use of the TPIA service could deploy these technologies to provide static IP addresses to
5. In their comments, the cable carriers indicated that there were significant costs to providing static IP addresses to TPIA service end-users through the proposed Managed Router solution. Provide an estimate of the development costs expected to be incurred by the company for implementation of the proposed Managed Router solution for the TPIA service. Identify the resources and activities required to implement this solution.
6. If the Commission directs each cable carrier to provide static IP addressing for its TPIA service, describe the tariff structure the company would propose to use to charge competitors for the static IP address capability. The response should identify, with supporting rationale, if the company would propose to provide the service separately or as part of the monthly TPIA service rate.

1. With reference to paragraph 15 of the cable carriers’ reply comments, the cable carriers submitted that “over the top” technologies such as VLANs and Point-to-Point Protocol over Ethernet (PPPoE) were potential alternatives for providing static IP addresses that ISPs could deploy themselves. Describe how ISPs that make use of the TPIA service could deploy these technologies to provide static IP addresses to end-users.
Interrogatories to Telus Communications Company (TCC)
1. In paragraph 11 of their comments, the cable carriers indicated that TCC, on its web site, noted that “For service plans with static IP addresses, a computer or device will have a
Long Lease IP address; however it must be requested via DHCP”. Describe the IP address allocation mechanism used by TCC to provide such IP addresses to end-users using DHCP. Provide the company’s rationale for using this approach, identifying any advantages over other potential approaches for “service plans with static IP addresses”.
2. In paragraph 13 of its comments, TCC submitted that “there should be less complex solutions available to the Cable Carriers to enable the wholesale ISPs to provide their solutions to their end-customers”. Identify and comment on “less complex solutions” that could be available to the cable carriers to enable the wholesale ISPs to provide their solutions to their end-customers.
