- Try this problem:
-
- I want to command a group of desktop computers distributed over
- the enterprise, possible for performing some management utility
- on all simultaneously. So I build a directed graph from my desktop
- to all the desktops for which I wish control. I need to solve
- the following problems:
-
- Message Acknowledgement:
-
- 1-a) I have one entry point VCI, which then branches down into the leaves
- of the directed graphs. For acknowledgment, can I execute a protocol
- within the network which collects the available acknowledgments at each
- node, then on collecting the proper amount passes it up the tree?
-
- 1-b) If a node requires an acknowledgment, can the control root pass
- down a re-transmission which passes just to that branch?
-
- Graph Building:
-
- 2) When building my directed graph, can I explore the total set of
- desktops, perform some local test to see if this is the desktop I want,
- then return either true or false to the network branch? The network
- branch then using this indicator to determine if the directed graph should
- pass through its internal node, thus updating the VCI?
-
- Topology Extraction:
-
- 3) Again, can I extract the topology of my directed graph, then just
- slip messages down a sequence of logical hops to reach a particular
- logical node, then possibly moving back into parallel transmission mode?
