Abstract: A system for and method of analyzing packet traffic in a packet-switched network, including collecting traffic logs from a network operations center, wherein the traffic logs are representative of packet traffic passing through an actual configuration of the network, and wherein each traffic log includes the time the traffic log was created and an associated packet's network entry and exit points. The collected traffic logs are stored in a computer such that the traffic logs can be replayed. A computer file is thereafter created and is representative of a modified network configuration that is different from the actual configuration of the network. The traffic logs are replayed in coordination with the modified network configuration to generate a histogram file representative of packet traffic passing through or via at least one of a host, node or link in the modified network configuration.

Abstract: A system and method for data distribution and recovery, including a server that broadcasts data to a plurality of clients and a means for a client to identify and recover broadcast data that the client missed while it was off line. In a representative embodiment, the system includes a transfer server, a plurality of clients in communication with the transfer server, and an archive in communication with the transfer server and the plurality of clients. The transfer server receives data packets from a data source, uniquely identifies each data packet, and broadcasts the data packets to the plurality of clients and the archive. Each client receives the data broadcast from the transfer server, identifies missing data, and communicates with the archive to recover the missing data.
