Abstract
Methods and systems for zero copy in a virtualized network environment are disclosed. Aspects of one method may include a plurality of GOSs that share a single NIC. The NIC may switch communication to a GOS to allow that GOS access to a network via the NIC. The NIC may offload, for example, OSI layerand/orprotocol operations from a host system and/or the GOSs. The data received from, or to be transmitted to, the network by the NIC may be copied directly between the NIC's buffer and a corresponding application buffer for one of the GOSs without copying the data to a TGOS. The NIC may access the GOS buffer via a virtual address, a buffer offset, or a physical address. The virtual address and the buffer offset may be translated to a physical address.
