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.
