Abstract
Described embodiments provide for a reassembly system for processing an asynchronous transfer mode (ATM) cell of data into an ATM adaptation layer (AAL) packet. A preprocessor module identifies a first conversation identification of one or more minipackets in the ATM cell, and reassembles the one or more minipackets having the first conversation identification into a portion of the AAL packet. A preprocessor determines if a trigger has occurred. In response to a trigger, the preprocessor sends a portion of the reassembled minipackets having the first conversation identification to a destination processor.
Claims20
A method of processing an asynchronous transfer mode (ATM) cell of data into an ATM adaptation layer (AAL) packet, the method comprising:
- identifying a first conversation identification of one or more minipackets in the ATM cell;
- reassembling the one or more minipackets having the first conversation identification into one or more common part sublayer (CPS) packets;
- determining, by a preprocessor, an occurrence of a trigger;
- in response to determining the occurrence of the trigger, sending the portion of the reassembled minipackets having the first conversation identification to a destination processor.
A reassembly system configured to process an asynchronous transfer mode (ATM) cell of data into an ATM adaptation layer (AAL) packet, the system comprising:
- a framer configured to arrange synchronous transport module data traffic in one or more frames;
- a destination processor coupled to a multiplexer;
- and
- one or more preprocessors, each coupled to the framer and the multiplexer, each configured to:
- identify a first conversation identification of one or more minipackets in the ATM cell;
- reassemble the one or more minipackets having the first conversation identification into one or more common part sublayer (CPS) packets;
- determining, by a preprocessor, an occurrence of a trigger;
- in response to determining the occurrence of the trigger, sending the portion of the reassembled minipackets having the first conversation identification to a destination processor.
A non-transitory, machine-readable storage medium, having encoded thereon program code, wherein, when the program code is executed by a machine, the machine implements a method for processing an asynchronous transfer mode (ATM) cell of data into an ATM adaptation layer (AAL) packet, the method comprising:
- identifying a first conversation identification of one or more minipackets in the ATM cell;
- reassembling the one or more minipackets having the first conversation identification into one or more common part sublayer packets;
- determining an occurrence of a trigger;
- in response to determining the occurrence of the trigger, sending the portion of the reassembled minipackets having the first conversation identification to a destination processor.
