Title: Bandwidth allocation
Inventor: SAFFRE FABRICE TRISTAN PIERRE
IPC: H04L47/762
Filed: 2004-09-08
Abstract: Access to a communications resource is controlled by limiting the maximum capacity made available to each of a plurality of users, by ranking the users according to their usage of the resource over a previous period, and restricting the availability of resource to each user by a restriction factor allocated to each user according to that user's ranking such that the greatest availability is allocated to the historically lightest users, thereby discouraging continuous heavy use of the resource whilst having little effect on the moderate user. The maximum capacity made available to each user bears an inverse relationship to the usage of the resource made by that user over a previous period, relative to the usage made by the other users.

Title: Dual use counters for routing loops and spam detection
Inventor: RUSCHE THILO
IPC: H04Q7/20
Filed: 2005-02-15
Abstract: A method for detecting an undesirable condition within a messaging network. A  message is received and a source of the message is identified. If an entry in a database for the source has not been created, an entry is created. A source counter for the source is then set to one and a timestamp is created for the source. If an entry in the database for the source has been previously created, the source counter is incremented by one and the timestamp is updated. The source counter is then compared to a source threshold, and if the source counter exceeds the source threshold over the course of predetermined amount of time, a source alarm is triggered. A sliding with respect to the predetermined amount of time may also be implemented to account for total counts that may fall across or be split by set periods of time. The invention is particularly useful for detecting "spam" events and undesirable routing loops.
