SYSTEM AND METHOD FOR FACILITATING ON-DEMAND PAGING IN A NETWORK INTERFACE CONTROLLER (NIC) - A simplified explanation of the abstract

This abstract first appeared for US patent application 18539907 titled 'SYSTEM AND METHOD FOR FACILITATING ON-DEMAND PAGING IN A NETWORK INTERFACE CONTROLLER (NIC)

Simplified Explanation

The abstract describes a network interface controller (NIC) with on-demand paging capabilities, consisting of a host interface, operation logic block, and address logic block. The NIC can receive requests for operations based on virtual memory addresses, translate addresses, and issue page requests if needed.

• Host interface couples NIC to host device
• Operation logic block processes remote device requests based on virtual memory addresses
• Address logic block handles address translations and issues page requests if needed

Potential Applications

The technology could be applied in networking devices, data centers, and cloud computing systems to improve memory management and data transfer efficiency.

Problems Solved

1. Efficient handling of virtual memory address translations 2. On-demand paging to optimize memory usage and performance

Benefits

1. Improved memory management 2. Enhanced data transfer efficiency 3. Reduced latency in processing operations

Potential Commercial Applications

Optimizing data center operations, improving network performance in high-traffic environments, enhancing cloud computing capabilities.

Possible Prior Art

Prior art may include existing NIC designs with memory management features, virtual memory address translation techniques, and on-demand paging mechanisms.

Unanswered Questions

How does the NIC handle multiple simultaneous page requests efficiently?

The abstract does not provide details on how the NIC prioritizes and processes multiple page requests at the same time.

What impact does on-demand paging have on overall system performance?

The abstract does not discuss the potential trade-offs or performance implications of implementing on-demand paging in the NIC.

Original Abstract Submitted

A network interface controller (NIC) capable of on-demand paging is provided. The NIC can be equipped with a host interface, an operation logic block, and an address logic block. The host interface can couple the NIC to a host device. The operation logic block can obtain from a remote device, a request for an operation based on a virtual memory address. The address logic block can obtain, from the operation logic block, a request for an address translation for the virtual memory address and issue an address translation request to the host device via the host interface. If the address translation is unsuccessful, the address logic block can send a page request to a processor of the host device via the host interface. The address logic block can then determine that a page has been allocated in response to the page request and reissue the address translation request.
