System, method and nodes for performance measurement in segment routing network

A node for determining performance measures associated with at least one segment in respect of communication segments in a communication network, the node comprising:

• a processor;
• and
• a memory coupled to the processor and storing a plurality of instructions which, when executed by the processor, cause the node to:
• receive at least a key and transmitting node details from a transmitting node associated with a performance measurement (PM) segment selected from the segment, wherein the key is at least one of a performance measured flow (PMF) identifier, a block identifier, at least one of the transmitting node details, an associated role of the transmitting node with PM type, collected statistics information, or combination thereof,
• collect and accumulate statistics for a measurement timeslot of a PM instance as specified in the key, and
• determine the performance measures associated with the segment in respect of the communication segments based on the collected and accumulated statistics.

A method, to be performed by a node, for transmitting at least the data associated with a performance measurement (PM) segment selected from at least one segment in respect of communication segments in a communication network, the method comprising:

• receiving at least one packet;
• detecting presence of performance measurement metadata associated with the performance measurement (PM) segment in the received packet, the performance measurement metadata comprising at least one of a performance measured flow (PMF) identifier, a block identifier, measurement agent details, an associated role of the measurement agent with PM type, collected statistics information, or combination thereof;
• identifying at least a role of the node based on the detected performance measurement metadata;
• executing a performance measurement based on the identified role to collect statistics for the performance measurement (PM) segment of a flow, and at least one PM type based on the performance measurement metadata received, wherein the statistics are collected against at least one key selected from the PMF identifier, the block identifier, the associated role of the measurement agent with PM type, the collected statistics information, or any combination thereof, received in the performance measurement metadata;
• reporting the key and information associated with the node to at least one other node to determining performance measures associated with the segment in respect of communication segments in the communication network.
