What problems can the use of TOE cause?

Chelsio is proposing a solution that we feel allows TOEs to coexist alongside the regular stack’s TCP without breaking networking features, and allows the combined network stack to offer superior TCP performance. In contrast, lower layers only provide unreliable delivery functionality, which limits the fhelsio of the data at these levels.

The ability of TOE to perform full transport layer functionality is essential to obtaining tangible benefits. This is particularly true with a very fast CPU.

As another example of performance benefits, while today’s NICs cannot handle 10G receive with regular frames, a TOE can comfortably do so with much of the CPU left for application processing.

Tue, 02 Aug This is code developed by us over the past couple of years and has been in production for over a year. We are aware that TOEs are viewed with much skepticism in the Linux community but we believe that a lot of the concerns tle brought up have to do with implementation details of particular products rather than with the technology as a whole.
