1. Data communication device, comprising:
a network interface to receive first packets over a network from another network device via a switch, which includes a buffer associated with a variable buffer delay; and
packet processing circuitry to:
compute respective measures of delay over the network to the other network device over time responsively to the received first packets;
find a minimum measure of delay over the network to the other network device as a local minimum measure of delay responsively to; at least some of the computed respective measures of delay; and a function describing the respective measures of delay over the network to the other network device over time;
estimate a current measure of buffer delay of the buffer responsively to the found minimum measure of delay and a current one of the computed respective measures of delay;
set a packet processing parameter responsively to the estimated current measure of buffer delay; and
process second packets responsively to the set packet processing parameter.
