Abstract: A cloud service provider's enterprise edge device and network interface are configured to establish a single tunnel connection with a remote server for delivering data packets to multiple distinct virtual machines on the remote server. The provider's enterprise edge device stores the network address information for each virtual machine and remote server to attach the destination network addresses to the data packet for transmission to the appropriate virtual machine on the remote server. Utilizing a single tunnel to transmit data packets to multiple virtual machines increases scalability at the provider's enterprise edge device and reduces system resources compared to other implementations in which the provider uses a tunnel for each virtual machine on a remote server.

Abstract: In a network virtualization system, metadata is passed in an encapsulation header from one network virtualization edge to another network virtualization edge or to a service connected to a network virtualization edge. The metadata may carry packet processing instructions, diagnostic information, hop-specific information, or a packet identifier. Using the metadata information in the packet header, the datacenter network may provide services such as remote segmentation offload, small packet coalescing, transparent packet compression, and end-to-end packet tracing.

Abstract: A system generates a probe packet including a probe flag and transmits the probe packet through a network tunnel to a destination computing system. The system receives from the destination computing system through the network tunnel an acknowledgment packet indicating receipt of the probe packet with the probe flag by the destination computing system. The system determines whether the transmitted probe packet and the received acknowledgment packet satisfy a packet loss condition. The system indicates packet loss based on the transmitted probe packet and the received acknowledgment packet satisfying the packet loss condition.

Abstract: A system for establishing network reliability for a computer network includes a plurality of initiating nodes to transmit a plurality of packets across the network and a plurality of receiving nodes to receive the plurality of packets via the network. A portion of the plurality of packets transmitted from the initiating nodes are appended with identifiers that correspond to characteristics of entities using the network. The plurality of receiving nodes transmit acknowledgement receipts associated with packets appended with the identifiers to a network monitoring system that monitors quality of service associated with the characteristics.
