Abstract: Method and system for managing transmit descriptors (TDs) for transmitting information over a network connection is provided. The method includes, allocating a minimum number of TDs to plural network connections at any given time; and determining an additional number of TDs for allocation to plural network connections, wherein the additional number of TDs is based on network traffic. The system includes a computing system with an operating system, a system memory and a network device driver; and a network adapter coupled to the computing system, wherein the operating system checks for availability of data for transmission over a plurality of network connections; and the network device driver allocates a minimum number of transmit descriptors (TDs) to the plural network connections at any given time; and determines an additional number of TDs for allocation to the plural network connections, wherein the additional number of TDs is based on network traffic.

Abstract: A method for sending/receiving a TCP segment is provided. The sending process includes, determining if a TCP port can be offloaded; saving a host system's time stamp value; replacing a host system's time stamp value with a TCP offload engine (“TOE”) adapter's time stamp value; and sending the TCP segment via the TOE adapter. The receiving process includes verifying if a TCP port is being offloaded by a host system to the TOE adpter; retrieving the host system's time stamp value; and inserting the host system's time stamp value in the received TCP segment before the forwarding the received TCP segment to the host system.
