Abstract: A method, apparatus, system, and machine-readable medium to bound data transmission latency by transmitting error verification data at a point during a data transmission related to a data transmission event is provided. Embodiments may comprise receiving an indication of a data transmission event, such as an end of a packet, and transmitting error verification data to a target device based upon the indication. More specifically, some embodiments transmit error verification data at an end of a packet to balance transmission latency against the bandwidth available from a communication medium.
