- walrus01 10y agoTo a certain extent the people who have a really firm grasp on the layer 1 through 3 topologies of the Internet, as it relates to business, contractual, transit, peering, IX, CDN, L2 inter-city transport relationships between ISPs don't want to write a comprehensive guide to this... If you have a mid sized ISP and the persons who make the final contractual/purchasing decisions on transport circuits, colo space, router equipment purchases have comprehensive knowldge of this, and detailed knowledge/GIS data for the OSI layer 1 network topology of the geographical area in which they operate, it provides a huge competitive advantage over other competing ISPs in the same area. If you look at CAIDA's ASRank tool, some of those top-100 ranked ASNs in North America leveraged their senior neteng and management's knowledge to make shrewd business decisions regarding how/where to build their network. Conversely the less successful ISPs waste capex and network engineering time and resources extending their network in ways that don't have the same ROI.
