Patexia is looking for descriptions of a method to manage the rate that a network node broadcasts a message to a portion of the nodes it’s connected to in order to avoid sending an overwhelming burst of network traffic. The method should accomplish this by broadcasting to a subset of recipients, waiting, then repeating the broadcast/wait cycle until the node transmits to all recipients.
Submitted documents describing this system must be:
- filed or published before 05/23/1997
- not on the known references list
The entire submission must describe a system where:
- the network of nodes are all directly connected to each other in some manner either through a dedicated trunk or a virtual circuit (see Figure 1 below)
- a node will recognize an event that requires it to send a message to other nodes that might be affected by the event
- that node will identify the other nodes that are affected by this event, which must only be a fraction of all the nodes it is connected to
- that node will then broadcast the message to only the affected nodes
- however, this broadcast will be limited to some predetermined maximum rate by broadcasting the message to a subset of affected nodes, waiting for a predetermined time delay, then repeating this broadcast/wait cycle until the node has finished broadcasting to all affected nodes
Figure 1 of US 877 showing each node (12) connected to the other nodes either through dedicated trunks (14) or virtual circuits (16)
This contest is for a prior art search for US Patent 6,130,877, with a focus on claims 1, 4, 8, and 11, in the context of a network systems administration standpoint of limiting the amount of traffic with which an individual node can flood the overall network.
|1||Is the reference either a US patent filed, a foreign patent published, or a non-patent document published before May 23rd, 1997?||T/F|
|2||Is the reference generally about managing the rate that a network node broadcasts a message to a portion of the nodes it’s connected to in order to avoid sending an overwhelming burst of network traffic?||T/F|
|3||Does the reference show a data communication network where each node has a direct connection to the other nodes in the network (e.g. through a dedicated trunk or a virtual circuit)?||5|
|4||Does the reference show that a node can broadcast a signal by (1) recognizing an event, (2) determining the network nodes affected by the event, and (3) broadcasting a message about this event to the selected affected nodes?||5|
|5||(4a) Does the reference further show that the selected nodes at step (2) are a fraction of the total number of connected nodes?||30|
|6||(4b) Does the reference explicitly use the term “broadcasting” to refer to the act of sending the message at step (3)?||5|
|7||(4c) Does the reference further show that the node controls the rate of broadcast by capping it to be no faster than a predetermined rate?||45|
|8||(7a) Does the reference further show that the rate of broadcast is controlled by (a) sending to a portion of the affected nodes, (b) waiting for a predetermined time delay, then repeating steps (a) and (b) until all the affected nodes from step (2) are broadcasted to?||10|
This is a Prior Art Search contest aimed at determining if a patent idea was known and publicly available before a patent was filed.
+5 bonus points will be awarded for non-patent literature and for foreign language references.
This contest will close on Wednesday, May 31st, 2015 at 11:59 PM PST.
