Title: Assaf Grunfeld: Innovator in TCP Offload Technology

Introduction

Assaf Grunfeld is a notable inventor based in Hod Hasharon, Israel. He has made significant contributions to the field of network technology, particularly in the area of transmission control protocol (TCP) offload. With a total of 5 patents to his name, Grunfeld's work has advanced the efficiency of data transmission in networking systems.

Latest Patents

Grunfeld's latest patents include a method and system for transparent TCP offload with best effort direct placement of incoming traffic. This innovation involves collecting TCP segments in a network interface card (NIC) processor without transferring state information to a host processor every time a TCP segment is received. When an event occurs that terminates the collection of TCP segments, the NIC processor generates a new aggregated TCP segment based on the collected segments. This method allows for direct transfer of the new TCP segment from memory to the user buffer, enhancing data processing efficiency.

Another significant patent by Grunfeld is a method and system for transparent TCP offload. This method also involves collecting TCP segments in a NIC processor without transferring state information to a host system. The collected segments are buffered in a coalescer, which verifies that the network flow has an entry in a flow lookup table (FLT). When the FLT is full, the coalescer closes the current entry and assigns the network flow to an available entry, updating the information in the FLT. Upon termination of the collection of TCP segments, the coalescer generates a single aggregated TCP segment for processing by the host system.
