ABSTRACT:
A communication system includes: a probe transmission server which transmits packets of a probe multicast at certain intervals on a same path as that of a main multicast; an aggregation server which converts multiple main cast and the probe multi cast into an aggregative multicast; and a communication control apparatus which determines an overall communication condition of the packets of the main multicast based on intervals of the probe multicast, wherein the communication control apparatus receives and recovers the packet of the main multicast from the packet of the aggregative multicast, if a communication break of the main multicast is detected.
