Network interoperability

From ITUwiki

Introduction

Public (and most private) ICT network and service providers collectively manage on a global array of distributed, essentially autonomous infrastructures at different logical layers (physical, transport, network, etc) that must be known to eachother with the ability to exchange and route traffic to addresses. The result is an enormous number of network-centric needs for trusted, current object, user, and provider identifiers, their correlation, and availability among providers. Time limited performance requirements are also especially significant for network interoperability. Diverse law and regulations combined with extensive industry normative standards and practices pertain to network interoperability.
