Methods and apparatus relating to network packet payload compression/decompression are described. In an embodiment, an uncompressed packet payload may be compressed before being transferred between various components of a computing system. For example, a packet payload may be compressed prior to transfer between network interface cards or controllers (NICs) and storage devices (e.g., including a main system memory and/or cache(s)), as well as between processors (or processor cores) and storage devices (e.g., including main system memory and/or caches). Other embodiments are also disclosed.

Aspects of the present disclosure relate to systems and methods for virtualizing mass storage using an interface card, or other special hardware unit, operatively coupled to a host system. In various implementations, the interface device and host system may collectively emulate a mass storage device for another “terminal” computing system in a manner that is transparent to the terminal system. Moreover, in various implementations, a mass storage device may be emulated in a manner that is transparent to the terminal system, without requiring modifications to the terminal platform's hardware or software architecture.

A method and system for substantially avoiding loss of data and enabling continuing connection to the application during an MTU size changing operation in an active network computing device. Logic is added to the device driver, which logic provides several enhancements to the MTU size changing operation/process. Among these enhancements are: (1) logic for temporarily pausing the data coming in from the linked partner while changing the MTU size; (2) logic for returning a “device busy” status to higher-protocol transmit requests during the MTU size changing process. This second logic prevents the application from issuing new requests until the busy signal is removed; and (3) logic for enabling resumption of both flows when the MTU size change is completed. With this new logic, the device driver/adapter does not have any transmit and receive packets to process for a short period of time, while the MTU size change is ongoing.
