Abstract
To solve a problem related to error correction. A communication apparatus includes: a PHY that receives a first transmission signal conforming to a predetermined communication protocol from a communication partner apparatus and performs error correction on a plurality of first packets included in the first transmission signal; and a LINK that separates the plurality of first packets after error correction and generates a second packet including error correction impossible information of the first packet on which the error correction has not been correctly performed, and the PHY transmits a second transmission signal including the second packet to the communication partner apparatus.
Claims16
A communication apparatus comprising:
- a physical layer (PHY) that receives a first transmission signal conforming to a predetermined communication protocol from a communication partner apparatus and performs error correction on a plurality of first packets included in the first transmission signal;
- a link layer (LINK) that separates the plurality of first packets after error correction and generates a second packet including error correction impossible information of at least one of the plurality of first packets on which the error correction has not been correctly performed, wherein
- the PHY transmits a second transmission signal including the second packet to the communication partner apparatus,
- the plurality of first packets includes at least one of an application packet or a first operation, administration, and maintenance (OAM) packet,
- the second packet includes a second OAM packet,
- the LINK includes an OAM unit that decodes the first OAM packet and generates the second OAM packet,
- the first OAM packet includes an error detection code, and
- the PHY detects an error in the first OAM packet on a basis of the error detection code and outputs an error detection signal;
- and
- a number-of-times storage unit that stores a number of times of detection of an error of the first OAM packet by the OAM unit for each transmission unit of the first transmission signal,
- wherein the second OAM packet includes information of the number of times stored in the number-of-times storage unit.
A communication method including:
- receiving, at a physical layer (PHY), a first transmission signal conforming to a predetermined communication protocol from a communication partner apparatus, and performing error correction on a plurality of first packets included in the first transmission signal;
- separating, at a link layer (LINK), the plurality of first packets after error correction and generating a second packet including error correction impossible information of the first packet in which the error correction has not been correctly performed;
- transmitting, by the PHY, a second transmission signal including the second packet to the communication partner apparatus, wherein
- the plurality of first packets includes at least one of an application packet or a first operation, administration, and maintenance (OAM) packet,
- the second packet includes a second OAM packet,
- the LINK includes an OAM unit that decodes the first OAM packet and generates the second OAM packet,
- the first OAM packet includes an error detection code, and
- the PHY detects an error in the first OAM packet on a basis of the error detection code and outputs an error detection signal;
- and
- storing a number of times of detection of an error of the first OAM packet by the OAM unit for each transmission unit of the first transmission signal,
- wherein the second OAM packet includes information of the stored number of times.
A non-transitory computer readable medium storing a program for communication, the program being executable by at least one processor to perform operations comprising:
- receiving, at a physical layer (PHY), a first transmission signal conforming to a predetermined communication protocol from a communication partner apparatus, and performing error correction on a plurality of first packets included in the first transmission signal;
- separating, at a link layer (LINK), the plurality of first packets after error correction and generating a second packet including error correction impossible information of the first packet in which the error correction has not been correctly performed;
- transmitting, by the PHY, a second transmission signal including the second packet to the communication partner apparatus, wherein
- the plurality of first packets includes at least one of an application packet or a first operation, administration, and maintenance (OAM) packet,
- the second packet includes a second OAM packet,
- the LINK includes an OAM unit that decodes the first OAM packet and generates the second OAM packet,
- the first OAM packet includes an error detection code, and
- the PHY detects an error in the first OAM packet on a basis of the error detection code and outputs an error detection signal;
- and
- storing a number of times of detection of an error of the first OAM packet by the OAM unit for each transmission unit of the first transmission signal,
- wherein the second OAM packet includes information of the stored number of times.
