In more detail, the layer:
|
|
* Receives incoming data and processes it into transactions and pdus.

* Fetches any PDUs it thinks it might have missed.
|
|
* Keeps the current state for contexts up to date by applying the
|
|
suitable conflict resolution.
|
|
* Sends outgoing pdus wrapped in transactions.
|
|
* Fills out the references to previous pdus/transactions appropriately
|
|
for outgoing data.
