LDC DILEMMA
• Political constraints in more developed areas of “bypassing” the incumbent with VoIP and thus regulatory or even criminal restraints of development. Control/loss of intl traffic.
• Tension between graduation of urban areas and commerce to next higher level of global market access and deploying basic access to rural areas—the universal access challenge

REGULATORY CHALLENGE
• Getting the courage to regulate creatively and around the traditional formats
• Encouraging private-municipality partnerships
• Exempting certain regions out of restrictive regulation

A best-effort network provides just what its name describes – a network that does its best to deliver packets in a timely manner. It is the least complex and costly network approach and is the design most networks use today. Best-effort networks work well for non-sensitive traffic types such as Web browsing and e-mail since delays in these services generally do not significantly impact the user experience.

Best-effort networks leverage Interior Gateway Protocol (IGP) technologies such as Open Shortest Path First (OSPF) and Intermediate System to Intermediate System (IS-IS) to determine paths for routing packets between hosts. IGP protocols use a Shortest Path First (SPF) algorithm to build routing tables. The routing engine references these routing tables at each router hop traversed by the packets. (continue reading…)
