A method, system, and media are provided for securely communicating data. One embodiment of the method includes encrypting a data stream by way of a first algorithm; creating at least two subsets of data from the data stream by extracting one or more data portions from the encrypted data stream, thereby leaving a remaining portion and an extracted portion; communicating the remaining portion to a destination by way of a first communications channel; encrypting the extracted portion utilizing a second algorithm; communicating the encrypted extracted portion to the destination by way of a second communications channel; and providing for recombining the remaining portion and the encrypted extracted portion to facilitate recovery of the encrypted data stream.

Encrypting a data transmission using multiple channels

The invention relates to a system and method for generating realistic network traffic by replaying captured network traffic using parallelized streams of subtraces. In accordance with one method of the invention, a captured trace of network traffic from a network link is provided. The captured trace is split into a number of subtraces. The subtraces are replayed and then recombined into a recombined trace, wherein the timing of packets in the recombined trace approximates the timing of packets in the captured trace.

System and method for trace replay using parallelized streams

A method for analyzing performance of a network, e.g., a communications network, is provided. In one embodiment, the method includes measuring detailed information relating to packet delays in routers and reporting the gathered information, for instance, using Simple Network Management Protocol (SNMP). The method hereof provides insight into through-router delays, such insights being particularly useful, for instance, for network providers who may have to comply with allowable delay statistics values across the domains they control.
