Embodiments of the invention relate to performing network communications according to an existing protocol by using frames that are larger than those usually allowed by the existing protocol. Thus, embodiments of the present invention provide for an extension of the existing protocol which allows for the use of larger frames. The larger frames may result from the use of larger payloads and their size may be defined in terms of the payload size. Embodiments provide for use of various negotiation and initialization mechanisms of the existing protocol with additional modifications to allow for the negotiation of the use of larger frames. These modifications may provide for end to end negotiation of a larger frame or payload size. Some embodiments ensure that the negotiations are performed in such a manner that devices that feature the improvements of the present invention can communicate with devices that do not feature these improvements.
