Title: Intelligent network adaptor with adaptive direct data placement scheme

Abstract:
The patent describes a system where a host computer is connected to a network through an intelligent network adaptor. This adaptor handles the protocol processing for an application on the host that is receiving data from a peer over the network. The system can selectively place incoming application data directly into the application's memory. This decision is made by the operating system, which provides the adaptor with information about the application's memory. Initially, data may be copied from a general host memory area to the application's memory, but subsequently, data can be placed directly into the application's memory by the intelligent network adaptor.

Plain-Language Overview of Independent Claims:

• Claim 1: This claim outlines a method for an intelligent network adapter and a host computer to determine the most efficient way to handle incoming data for an application. The system decides whether to place data directly into the application's memory based on the specific request from the application, particularly considering the size of the memory buffer the application has provided.

• Claim 2: This claim details a process where a part of the incoming data for an application is first stored in a temporary memory location on the host (not directly usable by the application) and is then copied over to the application's designated memory space.

• Claim 5: Similar to Claim 2, this claim describes copying a portion of the application's data from a temporary host memory area to the application's own memory. The distinction lies in the technical description of the temporary memory not being associated with the specific data connection.

• Claim 10: This claim covers a computer program product, such as a disk or other non-transitory medium, that contains software instructions. When a host computer runs these instructions, it is enabled to decide whether to have its intelligent network adapter place data directly into an application's memory. The instructions also cover the process of copying data from a temporary memory location to the application's memory.

• Claim 13: This claim also pertains to a computer program product with instructions similar to those in Claim 10. The subtle difference is in the characterization of the temporary memory from which the data is copied.

• Claim 16: This claim specifies a method for handling data within an ongoing, state-aware network connection. The method involves deciding where the intelligent network adaptor should place incoming data based on the application's request. It also includes the step of copying a portion of the data from a temporary host memory area to the application's memory.
