Abstract: Enhanced memory management schemes are presented to extend the flexibility of using either internal or external packet memory within the same network device. In the proposed schemes, the user can choose either static or dynamic schemes, both or which are capable of using both internal and external memory, depending on the deployment scenario and applications. This gives the user flexible choices when building unified wired and wireless networks that are either low-cost or feature-rich, or a combination of both. A method for buffering packets in a network device, and a network device including processing logic capable of performing the method are presented.
