Specifically, it defines the abstraction of a toaster that is visible to north-bound clients (e.g. the ...

Data Store  • Yang data is a tree- all staterelated data are modeled and represented as data tree to address any element / subtree • Two Logical Data Stores    • config     • operational • Unified View • InstanceIdentifier :    • Pointer to a node Data Store Transactions  • Multicast asynchronous communications, sent by Data Broker if there is change in conceptual data tree, and is delivered to subscribed consumers • Data Stores:    • Operational Data Tree - published by the providers using MD-SAL, represents a feedback loop for applications to observe state of the network / system.    • Configuration Data Tree - populated by consumers , represents intended state of the system / network预期状态 • Transaction Types    • Transactional modification to conceptual data tree - write transactions         newWriteOnlyTransaction()    • Transactional reads from curre...
