Abstract
An embodiment of the present invention is a technique to tag network transactions. A virtual queue stores packets received from and transmitted to a network interface card (NIC). A global session manager manages packet communication with a capability operating system (COS). A global virtual machine (VM) database stores global session identifiers (SIDs) of the packets and associated metadata. The global SIDs are used by the global session manager to track network sessions. The metadata describe characteristics of session connections. A VM tunnel connection encapsulates the packets passing to and from the COS.
