TPIA is a service offered to Internet Service Providers (ISP’s) by Rogers Cable. The service allows ISPs to provide their End- Users with high-speed Retail Internet Service via DOCSIS compliant cable modems attached to Rogers cable plant. To use the service, the ISP must connect to the aggregated Point Of Interconnect (POI) operated by Rogers. The aggregated POI is located at York Mills. Once connected at the POI, the ISP can offer service to End-Users served by the aggregated POI.
The components which, collectively, make up a third party ISP’s Third Party Residential Internet Service offering are depicted in the conceptual diagram below. It is important to note that the Cable Modem, End-User PC, RBS Transport Network and the ISP Network are not part of the Rogers’ TPIA service.
The Aggregated TPIA model is based on one MPLS VPN (vrf) per Phub for each ISP to segregate the traffic between PHUBs. The aggregated POI router will have a default route inside each VPN pointing to the ISP router, and propagate it to the same VPN on all CMTSes through MP-BGP. The default route will be configured to use the directly connected ISP router from the POI router, as the next hop. End-users’ traffic will follow the default route to reach their upstream ISPs respectively. The ISP router must be configured with static routes pointing to CPE IPv4 blocks for the specific PHUBs on the assigned VLANs. These VLANs will be provided by ISP to Rogers. The CPE IPv4 blocks must be provided by ISP.
VLAN Assignment The 1xGigE or 10xGigE links facing the ISP router will be configured as the trunk in Dot1Q mode to allow the traffic on VLANs coming from different PHUBs. A unique VLAN will be assigned to each physical link for each PHUB and these VLANs will be provided by ISP. These VLANs will be configured on the aggregated POI router on the backhaul links and will be mapped to the ISP network via the Dot1Q trunk. The VLANs must be unique on each physical link for each PHUB.
High-Level Network Diagram for aggregated TPIA
The following diagram shows the network interconnections on the aggregated POI. The diagram shows the scenario when an ISP has chosen RBS as a backhaul provider. Rogers will utilize its Transport Network to provision the backhaul from aggregated POI location at York Mills and terminate at 151 Front Street. Rogers will then handoff the fibre at the demarcation patch panel located in Meet Me Room
The Gateway Access Service (GAS) from Bell provides you with a low-cost solution for Internet access over Point-to-Point Protocol over Ethernet (PPPoE).
With this service, your business and residential customers can access the high-speed Internet using existing telephone lines. Based on ADSL (asymmetric digital subscriber line) technology, applications include high-speed Internet access and remote LAN connectivity.
GAS is offered on two different platforms to meet the dynamic needs of your customers, including:
Using dedicated network point-to-point Ethernet, Internet Connect – Dedicated Internet Access (IC-DIA) from Bell bundles access and transit to provide a complete solution with the speed and performance your business customers can rely on.
Delivered over Canada’s largest fibre optic network, IC-DIA offers flexible, secure, dedicated Internet connectivity.
