Introduction Client-layer network and server-layer network have been respectively modeled to allow the tunnels carrying the client traffic. Server- layers are modeled as tunnels with various switching technologies, such as OTN in [I-D.ietf-ccamp-otn-tunnel-model] and WSON in [I-D.ietf-ccamp-wson-tunnel-model]. Client-layers are modeled as client signals according to the client-signal identities specified in [I-D.ietf-ccamp-layer1-types]. These client signals can be configured to existing tunnels via the client signal configuration model specified in [I-D.ietf-ccamp-client-signal-yang]. Zheng, et al. Expires 15 July 2023 [Page 2] Internet-Draft PM YANG for Client Signal January 2023 In the network operation, the operator is interested in monitoring their instantiated client signal over tunnels. The objective of such monitoring is to complete timely adjustment once there is abnormal statistic which may result in failure of the client signal. The parameters specified in the performance monitoring model can be collected for the operation need. The OAM mechanism, can be configured together with the performance monitoring model. 2. Terminology and Notations A simplified graphical representation of the data model is used in this document. The meaning of the symbols in the YANG data tree presented later in this document is defined in [RFC8340]. They are provided below for reference. * Brackets "[" and "]" enclose list keys. * Abbreviations before data node names: "rw" means configuration (read-write) and "ro" state data (read-only). * Symbols after data node names: "?" means an optional node, "!" means a presence container, and "*" denotes a list and leaf-list. * Parentheses enclose choice and case nodes, and case nodes are also marked with a colon (":"). * Ellipsis ("...") stands for contents of subtrees that are not shown. 3. Model Relationship [I-D.ietf-ccamp-client-signal-yang] has specified the two models for the client signal configuration, module ietf-trans-client-service for transparent client service and module ietf-eth-tran-service for Ethernet service. Basically the client signal types in this document is consistent with ietf-eth-tran-types, and focus on different functionality. On the perspective of operator, the modules in [I-D.ietf-ccamp-client-signal-yang] can be used to configure the service given any underlay tunnels, while the operation about monitoring the performance on given service can be achieved by using the model in this document. Zheng, et al. Expires 15 July 2023 [Page 3] Internet-Draft PM YANG for Client Signal January 2023 Consideration on Key Performance Information (KPI) monitoring for Virtual Network (VN) and tunnels has been specified in [I-D.ietf-teas-actn-pm-telemetry-autonomics]. Usually the monitoring on the tunnels are the VNs should be separately deployed for the network operation, but it is possible to have common parameters that are both needed for the VN/TE and the configured services. Common types are imported in both modules. VPN-level parameters and their monitoring have been defined in [I-D.www-bess-yang-vpn-service-pm]. This module focus on the performance on the topology at different layer or the overlay topology between VPN sites. On the other hand, this document is focusing on the performance of the service configured between Customer Ends (CE). 4. Consideration on Monitoring Parameters There can be multiple groups of parameters for monitoring, such as latency, bit error rate (BER). Some of these parameters are layer- dependent, for example, packet loss is only applicable in packet networks are won't be neede for layer 1 OTN and layer 0 WSON. This document starts with the specification of the latency measurement for both Ethernet service and client signal service. In the future version additional parameters would be added into the data model in the same approach as the latency in the current version. A candidate list of parameters to be monitored include: Latency, Packet Loss, Bit Error Rate (BER), Jitter, Bandwidth, Byte/Packet number and so on. 5. OAM Configuration The operation, administration and maintenance protocols and data models have been specified in [RFC8531] for the connection-oriented network. The model is referenced in this work to develop an Ethernet-specific OAM models, which is augmenting the service performance monitoring data model. The definitions of OAM terminologies, such as maintainence Maintenance Domain (MD), Maintenance Association (MA), and Maintenance End Points (MEP), can be found in [RFC8531] as well. 6.
