Abstract

In one example embodiment, a system and method is illustrated that includes processes a first data packet using a first operating system, the first data packet received from a first network. A second operation is shown that processes a second data packet using a second operating system, the second data packet received from a second network. Further, an additional operation is shown that determines a route associated with the first data packet and the second data packet, the route including at least one of a logical route or physical route. Moreover, an operation is shown that parses the first data packet into at least one first logical segment, and parsing the second data packet into at least one second logical segment. An operation is shown that transmits the first logical segment and the second logical segment as at least one data packet across the WAN.
