Abstract

The invention discloses a caching device and method. The caching device comprises a caching control module and a PMAU (Packet Memory Allocated Unit) application module, wherein the caching control module comprises a first judgment unit, a request unit, a receiving unit and a caching unit; the first judgment unit is used for judging whether a data packet to be cached exists or not; the request unit is used for requesting the PMAU module to allocate a PMAU number for the data packet when the judgment result is positive; the receiving unit is used for receiving the PMAU number which is allocated for the data packet by the PMAU module; and the caching unit is used for caching the data packet to a caching space corresponding to the PMAU number. The caching device and method have the advantage that high performance and high bandwidth requirements of GPON ONU (Gigabit-capable Passive Optical Network Optical Network Unit) service are met.

Description

technical field [0001] The present invention relates to the communication field, and in particular, to a cache device and method. Background technique [0002] Gigabit-capable Passive Optical Networks (GPON for short) is an emerging technology. As a passive optical network (PON for short) series of technologies, the architecture is the most complete and the standard content is the most complete. , The next-generation network technology with broad application prospects has been widely concerned. It is the basis of the next-generation access network and the best solution to replace the current asymmetrical digital subscriber line (Asymmetrical Digital Subscriber Line, referred to as ADSL) access technology. In the future access network market, there are huge business opportunities and very broad market prospects. [0003] The Optical Network Unit (ONU for short) is one of the core chips of the PON chip. In the GPON system, the GPON ONU is a bridge connecting the central offi...
