Abstract
In an apparatus for a performance management of a label switching path (LSP) set in a multi protocol label switching (MPLS) network and a method thereof, a determination is made as to whether the LSP satisfies a required performance criterion in the network, and protection of the LSP or replacement of the LSP not satisfying the required performance with a substitute LSP is carried out.
Claims19
An apparatus for performance management of a multi protocol label switching (MPLS) network in which a traffic transfer is conducted through a preset label switching path (LSP), the apparatus comprising:
- an LSP monitoring section which receives a performance measurement value of an LSP from a respective MPLS edge switch (MES), compares the performance measurement value with a certain threshold to output an analysis value, and calls for protection of the LSP when the outputted analysis value satisfies a certain condition;
- and
- an LSP computation section which, when a request for the protection of the LSP is received from the LSP monitoring section, determines whether a substitute LSP for replacing the LSP exists, and wherein, when the substitute LSP exists, the LSP is replaced by the substitute LSP, and wherein, when the substitute LSP does not exist, a substitute LSP is set, and the LSP is replaced by the substitute LSP.
An apparatus for performance management of an MPLS network in which an LSP is set and managed through a centralized control method, the apparatus comprising:
- an LSP monitoring section which receives a performance measurement value of an LSP from a respective MPLS edge switch (MES), compares the performance measurement value with a certain threshold to output an analysis value, and calls for protection of the LSP when the outputted analysis value satisfies a certain condition;
- and
- an LSP computation section which, when a request for the protection of the LSP is a received from the LSP monitoring section, determines whether a substitute LSP for replacing the LSP exists, and wherein, when the substitute LSP exists, the LSP is replaced by the substitute LSP, and wherein, when the substitute LSP does not exist, a substitute LSP is set, and the LSP is replaced by the substitute LSP.
A multi protocol label switching (MPLS) network, comprising:
- an MPLS edge switch (MES) for measuring a performance value of a label switching path (LSP);
- and
- an apparatus for performance management which receives the performance value from the MES, compares the performance value with a certain threshold to output an analysis value, and calls for protection of the LSP when the outputted value satisfies a certain condition.
A multi protocol label switching (MPLS) network, comprising:
- an MPLS edge switch (MES) which measures a performance value of a label switching path (LSP) and compares the measured performance value with a certain threshold to output an analysis value;
- and
- an apparatus for performance management which receives the analysis value from the MES, and calls for a protection of the LSP when the received analysis value satisfies a certain condition.
A method for performance management of a multi protocol label switching (MPLS) network in which traffic transfer is conducted through a preset label switching path (LSP), the method comprising the steps of:
- (a) measuring a performance value of the LSP;
- (b) deriving an analysis value by comparing the measured value of the LSP to a certain threshold;
- (c) determining whether the analysis value satisfies a certain condition;
- and
- (d) determining that protection of the LSP is appropriate when the analysis value satisfies the certain condition.
