1. Streaming Discussion
Nigel Davis

2. Core Overall purpose Architecture Discuss various cases Interactions
To achieve client “eventual consistency” with the network ongoing
Use some material from the TAPI document to highlight context etc.
Architecture
Highlight expected responsibilities
Use diagrams from TAPI document and the model (next two slides)
Discuss various cases
Consider diagram from TAPI document
Interactions
Basic
Grammar
Approaches and implications

3. Core Model work Work in both Control Model and Interaction Model
Add a log to the control model
Base this on the storage model
Use a generalized store with decoration to make it a log and with relevant parameters
Identify topics
Show the log in the context of the ControlPort
Model parameters for key log strategies
Simple bounded log: Time bounded, size bounded
Long history log with periodic baselines
Compacted log: Simple, with tombstones and compaction
Develop symbol set
Show the log being fed from an ExposureContext
Show a Topic based port on ExposureContext?
Represent application
Specific applications
Align/notify
Get snapshot
Show both client and provider engagement and responsibility
Describe interactions and pattern
Specific interactions
From start
Get next
From point
Specific chunk
Develop sequence diagrams for applications using interactions
E.g., sequence is for align/notify for compacted log of alarms
Show client and provider interactions
