Re-timing a packetized radio flow to clean noise induced by packet delay variation of a packet network

One or more non-transitory computer readable storage media encoded with instructions that, when executed by a processor, cause the processor to perform operations, comprising:

• receiving, at a first node of a fronthaul network, a Radio over Ethernet (RoE) frame transmitted by a second node of the fronthaul network, wherein the RoE frame comprises a Common Public Radio Interface (CPRI) bit stream associated with a first radio device of the fronthaul network, a sequence number, and a first time stamp;
• generating a second time stamp by the first node upon receiving the RoE frame;
• calculating an induced delay value based, at least in part, on the first time stamp and the second time stamp;
• calculating a re-timing value based on a re-timing interval and the induced delay value;
• and
• transmitting the CPRI bit stream to a second radio device of the fronthaul network based on the re-timing value.

A system comprising:

• at least one memory element for storing data;
• and
• at least one processor for executing instructions associated with the data, wherein executing the instructions causes the system to perform operations, comprising:
• receiving, at a first node of a fronthaul network, a Radio over Ethernet (RoE) frame transmitted by a second node of the fronthaul network, wherein the RoE frame comprises a Common Public Radio Interface (CPRI) bit stream associated with a first radio device of the fronthaul network, a sequence number, and a first time stamp;
• generating a second time stamp by the first node upon receiving the RoE frame;
• calculating an induced delay value based, at least in part, on the first time stamp and the second time stamp;
• calculating a re-timing value based on a re-timing interval and the induced delay value;
• and
• transmitting the CPRI bit stream to a second radio device of the fronthaul network based on the re-timing value.
