The document proposes an infrastructure for establishing e-government in Sri Lanka through improved government-to-government (G2G) communication and information sharing. It discusses two types of G2G models - internal and external facing. While Sri Lanka has an "eSri Lanka" roadmap for e-government, there is no implemented system for intra-government communication. The proposed solution designs and simulates a communication system to organize G2G services and increase effectiveness and efficiency by 75%. The infrastructure could help establish e-government in Sri Lanka.
