Multi-layer Coordination Sample Clauses

Multi-layer Coordination. ‌ In RINA, the situation is very different. Using a common API (the IPC API) and building immutable infrastructure used by each and every IPCP means that there are no longer an technological differences among different layers in the network. There are also no differences between vertical elements in a component, everything is an IPC process (IPCP). Next, the concept of separation of mechanism and policy, and the definition of policies for all aspects of an IPCP (and thus inter-process communication), makes all available policies ex- plicit. There is no need anymore for separate management model interface definitions, everything management requires is already defined by the architecture. Next, the concept of a DIF as a layer, and not a stack, with autonomic functions for layer management (as part of every IPCP) and with an explicit definition of the scope of the layer (the scope of the DIF, realised by its policies), provides for a very new concept with regard to multi-layer management. Last but not least, the RIB in the IPCPs (and thus in the DIF) provides for the required information base for all of the above. The RIB maintains all shared state of all IPCPs in a DIF. The defined processes also realise an automatic update of this shared state amongst all IPCPs in a DIF. This means that changes to a DIF’s configuration will propagate from one IPCP to another until the entire DIF is reconfigured.
