list and, if able and willing, send the requested file directly to the
requesting node on a P2P basis. (Specification 5-6).
2. If a request remains unfulfilled after a specified time period, the
system may assume that there is a low likelihood of it ever being
filled and may remove the request from the list of requests. In the
Specification, this process is called the aging of requests.
(Specification 7, l. 10 ff).
3. The Traversat Patent Application Publication provides a system and
method for a P2P network in which special rendezvous nodes
contain information, called advertisements, about network resources
to help other nodes locate those resources long range on the network.
(¶ 0026). Requests from one node are sent to other nodes in search
of responses or of advertisements. (¶ 0029). Query requests may
include a time-to-live indicator, which defines the expiration of the
request and signals that the request may be deleted or invalidated, as
they are unlikely to be filled. (¶ 0028).
4. The Teng Patent teaches a system in a network for requesting a
future time to transfer a file across the network from one node to
another. The requests may be sorted, prioritize and timed to
efficiently transfer files. A request to transfer a file which is ignored
results in the file not being transferred to the node that received the
request. (Col. 2, ll. 1-21).
