Views Architecture
|
|
------------------
|
|
|
|
Vies are used to group interfaces into loginal interfaces.
|
|
When using views the sub/real interfaces handle flows only, hosts are allocated in the view interface only.
|
|
|
|
There is a SPSC queue for each sub/real interface belonging to the view interface.
|
|
|
|
NetworkInterface::viewEnqueue enqueues flows, from Flow::housekeep (incUses is used to make sure flows are not purged when still in use)
|
|
ViewInterface::viewDequeue dequeues flows in the view interface
|
|
|
|
viewed_flows_walker takes care of hosts allocation/update with the flow information coming from the sub/real interfaces.
|
|
|
|
Note:
|
|
- in the real interface there is no host allocation, as a consequence of this the Flow contructor allocates IpAddress (cli_ip_addr) instead of Host (cli_host)
|
|
- hosts are "Shared" between sub/real interfaces (pay attention to concurrent access)
