PROVIDING HIGH ASSURANCE OF END-TO-END CPRI CIRCUIT IN A HIGH JITTER PACKET BASED FRONTHAUL NETWORK - A simplified explanation of the abstract
This abstract first appeared for US patent application 17824077 titled 'PROVIDING HIGH ASSURANCE OF END-TO-END CPRI CIRCUIT IN A HIGH JITTER PACKET BASED FRONTHAUL NETWORK
Simplified Explanation
The abstract describes a method for ensuring reliable packet delivery in a network with high jitter.
- The method involves detecting when a data packet is missing and inserting an idle packet in its place.
- The packet playout process is continuously monitored to track the last valid packet played, the number of idle packets inserted, and the number of packets in the buffer.
- When it is determined that no more idle packets should be inserted, a valid packet is played out.
- This process helps maintain link integrity between network elements.
Original Abstract Submitted
The present disclosure is directed to ensuring end-to-end packet delivery in a Common Public Radio Interface (CPRI) circuit with a high jitter packet-based fronthaul network. In one aspect, a method includes determining, at a de-mapper, that at least one data packet scheduled to be played out is not available; inserting an idle data packet into a buffer at the de-mapper for each data packet that is not available; continuously monitoring a packet playout process to (1) identify last valid data packet played out, (2) a number of idle data packets inserted, and (3) a number of data packets currently stored in the buffer; and determining that insertion of idle data packets into the buffer should be stopped and a valid data packet to be played out; wherein inserting the idle data packet and the valid data packet ensure link integrity in data packet transmission between two network elements.
