Introduction Architecture Prototype Evaluation Conclusion Motivation Network nodes are equipped with enhanced resources advanced endsystem intelligence support for complex operations This offers new service deployment options For example hybrid group communication combine native IP and overlay multicast endsystems participate in routing and forwarding A H Mcast – Meiling 3

Introduction Architecture Prototype Evaluation Conclusion Objectives Decouple application development from service deployment Universal service access through standardized APIs Adaptive service instantiation at runtime, depending on local network environment and node capabilities Provide incremental deployment and service evolution A H Mcast exemplary implements a universal multicast service A H Mcast – Meiling 4

Introduction Architecture Prototype Evaluation Conclusion Issues for Future Internet Services Globally available network services rely on: uniform deployment within networks and endsystems widely available (standardized) service APIs Requires support by vendors of hardware and operating systems Multicast specific issues: Divergent deployment states of multicast technologies Incompatible APIs for various multicast flavors Conflicting incentives for usage and deployment A H Mcast – Meiling 5

Introduction Architecture Prototype Evaluation Conclusion A H Mcast Architecture System oriented multi service architecture Building blocks for new services: technology transparent, universal service API extended middleware functionality on endsystems evolutionary, incremental service deployment A H Mcast multicast service consists of: an abstract naming scheme based on URIs (LocID split) the common multicast API, conforms to IRTF draft [1] a middleware component for endsystems Interdomain Multicast Gateways (IMGs) A H Mcast – Meiling 6
