Genes Telecom is an established residential and business Service Provider in Northern Manitoba. Specifically The Pas and surrounding area (Cranberry Portage, Wanless, Bakers Narrows, Rocky Lake, Clearwater Lake, & Flin Flon), Thompson, and Snow Lake.

Before

A previous network redesign project had taken the network from a flat layer 2 network to a fully routed OSPF network, using BGP externally.

QoS and VPLS

The next level up from fully routed ISP network is a Service Provider (SP) network. The most commonly supported way to accomplish this is by using MPLS, and VPLS to provide layer 2 services (with priority levels) across that fully routed MPLS network.

Changes and improvements:

  1. Internal BGP Anycast
  2. MPLS
  3. Layer 2 service delivered over VPLS
  4. QoS everywhere using Layer 3 DSCP bits, Layer 2 VLAN priority bits, and MPLS EXP bits
