Abstract: A traceroute command may be used to diagnose a computer network or provide additional information regarding a computer network. A traceroute command may be provided to applications executing within a virtualized environment by allowing commands to be passed from the virtualized environment to a host operating system through a network interface. The traceroute command may be executed by the host operating system, and network information returned to the application in the virtualized environment.

Abstract: A fast send method may be selectively implemented for certain data packets received from an application for transmission through a network interface. When the fast send method is triggered for a data packet, the application requesting transmission of the data packet may be provided a completion notice nearly immediately after the data packet is received. The fast send method may be used for data packets similar to previously-transmitted data packets for which the information in the data packet is already vetted. For example, a data packet with a similar source address, destination address, source port, destination port, application identifier, and/or activity identifier may have already been vetted. A socket table may be maintained listing previously-transmitted data packets and an instruction for handling additional data packets similar to the data packet entered in the socket table.

For example, a data packet with a similar source address, destination address, source port, destination port, application identifier, and/or activity identifier may have already been vetted. Data packets sent through the fast send method may be throttled to prevent one communication stream from blocking out other communication streams. For example, every nth data packet queued for the fast send method may be transmitted by a slow send method.
