초록 ▼

A method is disclosed for providing packet error indication in a multi-hop communications system in which packets of data are transmitted from a transmission site to a reception site via a plurality of successive physical links. According to the method, at the transmission site, a pre-defined bit in a packet to be transmitted is set to a first value, the first value indicating that no errors are present in the packet. Then, at each successive physical link in the communication system, after transmission of the packet over that physical link, the following steps are performed: (a) detecting whether any uncorrectable errors occurred in the packet during transmission over that physical link; (b) if an uncorrectable error is detected, setting the pre-defined bit in the packet to a second value wherein the second value is indicative of an uncorrectable error in the data of the packet; and (c) relaying the packet to the next successive physical link for transmission over that next link. A decoder at the reception site may, upon receiving a given packet, examine the value of the pre-defined bit to determined the integrity of the data contained in that packet.

In a packet-based multi-hop communications system wherein packets of data are transmitted from a transmission site to a reception site via a plurality of successive physical links, and wherein each successive physical link employs a data link layer unique to that physical link to provide error correction of packets transmitted over that physical link, and wherein the data link layers of some of said physical links may be different, a method of indicating to the reception site whether an error occurred during transmission of a particular packet over one of said physical links, said method comprising the steps of: setting a pre-defined group of bits in said packet to a first value at said transmission site, said first value being indicative of no errors in the data of said packet; performing the following steps at each successive physical link after transmission of said packet over that physical link: (a) detecting, via the data link layer employed by that physical link, whether any uncorrectable errors occurred in the packet during transmission over that physical link; (b) extracting the packet from the data link layer employed by the physical link; (c) if an uncorrectable error is detected, setting the pre-defined group of bits in the extracted packet to a second value wherein the second value is indicative of an uncorrectable error in the data of said extracted packet; and (d) relaying said extracted packet to the next successive physical link, wherein the next successive physical link employs another data link layer to transmit said packet over that physical link, and wherein a device at the reception site may, upon receiving the packet, examine the value of the pre-defined group of bits to determine whether an uncorrectable error occurred during transmission of the packet over one of said physical links.
