Latency feedback for optimizing a third-party link

A transmitter adapted to receive latency feedback packets for determining a third-party-link ingress-memory size comprising:

• a memory for storing an Ethernet stream sourced from the network;
• a processor configured to split the Ethernet stream from the memory into a plurality of frames, wherein the processor is configured to transfer the plurality of frames to at least one data path;
• a media access port (MAC) for transmitting the plurality of frames via the at least one data path, wherein the at least one data path is a third-party-link;
• and
• wherein the processor is adapted to execute a transmitter code configured to (1) insert a time-stamp value into the plurality of frames;
• (2) transmit the plurality of frames via the at least one data path;
• (3) increase the transmission capacity until detecting a first threshold via a latency feedback packet to fill a third party ingress-memory for an upper edge-scenario protection;
• (4) decrease the transmission capacity until detecting a second threshold via the latency feedback packet to empty a third party ingress-memory for the lower edge-scenarios protection;
• and (5) adjust the transmission capacity, raising and lowering capacity until reaching a hysteresis value for a latency feedback value;
• wherein the processor is further configured to calculate determine at least one of a third-party ingress memory capacity and a rate of change of the latency feedback value based on one or more derivatives of the latency feedback value.
