Before and After Host Hardware Offload

Figure 1 below depicts the percentage of CPU power used by TCP/IP processing as compared with a typical server application.

The image on the left shows a typical ratio of CPU processing distribution before Tehuti Networks’ offloading technology is integrated on a platform. Only a very limited amount of CPU power is available for the applications, with the vast majority of CPU power being monopolized by the TCP/IP processing tasks.

The image on the right shows the significant benefits achieved after integrating Tehuti Networks’ host hardware offload solution. The CPU's involvement in TCP/IP processing drops considerably, extensively increasing the time it allocates to its applications, thus increasing the CPU’s efficiency by decreasing the valuable time and/or memory bandwidth being dedicated to TCP/IP processing.

* Depending on application

Tehuti Networks’ Technology Advantages 

• Power budgets and costs similar to those of the simple MAC.

• Near 10Gbps line rate performance.

• The host hardware offload controller can be implemented in the same manner as a regular LAN on Motherboard (LOM) or Network Interface Card (NIC).  The chip replaces the MAC of any standard TCP/IP connection.
