Meta-communications in component-based communication frameworks for grids

— Applications are faced with several network-related problems on current grids: heterogeneous networks, firewalls, NAT, private IP addresses, non-routed networks, performance problems on WAN. Moreover, the requirements concerning communications are varied and the acceptable tradeoffs highly depends on the applications. A solution to reach the flexibility regarding communication on grids is the use of a componentbased communication framework. The users then compose their own protocol stacks by assembling building blocks in the way they want. However, a truly flexible and dynamic componentbased communication framework needs a meta-communication channel for its out-of-band communications required by dynamic component assembly in a consistent way on multiple nodes. The meta-communication channel is useful for some “brokered” communication methods, too, and in particular those designed to cross firewalls. The meta-communication channel has often been the “weakest link” of com...
