Verfahren zum Suchen eines Paketübertragungspfads in einem Breitbandinformations- und -kommunikationssystem

摘要

A method of searching for a packet transmission path in a broadband information and communication system includes the steps of temporarily storing an incoming packet containing a destination subscriber's address to which the packet should be transmitted; checking whether any packet has ever been transmitted to the address contained in the stored packet; when it is determined that any packet has ever been transmitted to the address, transmitting the stored packet over a path over which previous packet has been transmitted to the address; when it is determined that no packet has been transmitted to the address contained in the stored packet, sequentially searching for a corresponding packet transmission path for transmitting the stored packet, storing a searched path together with the address, and then transmitting the stored packet over the searched path.
