Abstract
A method of restricting transmission of data packets from a host entity in a network, including: transmitting outgoing packets to destination hosts whose identities are contained in a record stored in a working set of host identity records; over the course of repeated predetermined time intervals, restricting, to a predetermined number, destination hosts not identified in the working to which packets may be transmitted; upon transmission of a packet to a host whose identity is not contained in a record in the working set, adding a record containing the host's identity to the working set and attributing a time to live to the record; deleting each record from the working set whose time to live has expired.
