+# Layer 2 Monitoring with CFM and SOAM in ONOS
+
+Connectivity Fault Management (CFM) was first introduced in IEEE 802.1ag, which 
+has been superseded by IEEE 802.1Q-2011 and subsequently by IEEE 802.1Q-2014 - 
+the IEEE Standard for Local and metropolitan area networks - Bridges and Bridged 
+Networks.
+
+It defines protocols and practices for OAM (Operations, Administration, and 
+Maintenance) for paths through 802.1 bridges and local area networks (LANs). 
+It is an amendment to IEEE 802.1Q-2005 and was approved in 2007.
+
+IEEE 802.1ag is largely identical with ITU-T Recommendation Y.1731, which 
+additionally addresses performance monitoring.
+
+In addition the Metro Ethernet Forum (MEF) has defined SOAM (Service Operations 
+Administration and Management) in MEF-17 on top of these standards to build a 
+framework for monitoring in conjunction with MEF services. This and other MEF 
+standards are available in their technical documentation section.
+
+## Modelling
+Working these combined standards into a unified model is a complex task an 
+inevitably requires some compromises. For instance while  802.1Q talks about 
+Maintenance Domains and Maintenance Associations the MEF 17 standard uses the 
+name Maintenance Entity (ME) and Maintenance Entity Group (MEG). MEF 38 and 39 
+defines a model that encompasses all of the concepts as a set of YANG modules, 
+that separate out the Monitoring aspects of MEF 17 from MEF Carrier Ethernet 
+Services. In this way a loose coupling exists between the CFM and MEF Services 
+linked together only through VLAN ids. 
+
+MEF 38 defines a root object mef-cfm which represents 802.1Q and Y.1731 CFM 
+entities, which is augmented by mef-soam-fm which adds on additional attributes 
+and operations from SOAM related to fault management.
+
+MEF 39 augments mef-cfm further with the performance management aspects of SOAM 
+as mef-soam-pm including monitoring of delay, jitter and loss measurements.
+
+These YANG models act as a unified definition of these standards that it makes 
+practical sense to reuse in ONOS.
+
+## Implementation in ONOS
+Direct translation of the MEF 38 and MEF 39 YANG models into ONOS does not provide 
+a completely clean way to define the models in ONOS, because of the complication 
+brought by the augments. Instead the models have been defined independently in 
+ONOS as a new structure under reusing common ONOS classes such as DeviceId, 
+PortNumber, NetworkResource, Identifier, MacAddress etc. 
+
+* onos/incubator/src/main/java/org/onosproject/api/net/l2monitoring/cfm
+* onos/incubator/src/main/java/org/onosproject/api/net/l2monitoring/soam
+
+## Java Model
+These immutable objects are defined as Java POJOs with little dependencies on 
+outside elements, and built the familiar builder pattern. 
+
+As with 802.1Q the model’s top level starts with the Maintenance Domain - an 
+abstract reference object defining the span of the domain of activity for 
+maintenance in the network. Maintenance Domains are defined at 8 different levels 
+to indicate the scope of their span.
+
+Beneath the Maintenance Domain is the Maintenance Association, another abstract 
+object specific to a VLAN that contains common parameters for a group of MEPs 
+(Maintenance Association Endpoints). It is these MEPs that are created on devices 
+in the network and can be thought of as monitoring points. Devices must support 
+the CfmMepProgrammable behaviour to support the creation of MEPs.
+
+The MEP is the key item then that allows specific actions to be taken on devices 
+such as 
+
+* Continuity Check Messaging (CCM)
+* Loopback testing
+* Linktrace testing
+
+In addition these MEPs allow the creation of 
+* Delay Measurement entities (which run tests for Delay and Jitter on a continuous basis)
+* Loss Measurement entities (which run tests for Loss Measurement on a continuous basis)
+
+The following shows the structure of Java classes defined in ONOS to represent 
+these entities.
+
+`Maintenance-Domain*`<br/>
+&nbsp;`|-MdId` (MdIdCharStr or MdIdDomainName or MdIdMacUint or MdIdNone)<br/>
+&nbsp;`|-Maintenance-Association*`<br/>
+&nbsp;&nbsp;&nbsp;`|-MaIdShort` (MaIdCharStr or MaIdPrimaryVid or Ma2Octet 
+                                     or MaIdRfc2685VpnId or MaIdIccY1731)<br/>
+&nbsp;&nbsp;&nbsp;`|-Component*`<br/>
+&nbsp;&nbsp;&nbsp;`|-Mep*` (Maintenance-Association-EndPoint) and MepEntry*<br/>
+&nbsp;&nbsp;&nbsp;|&nbsp;`|-MepId`<br/>
+&nbsp;&nbsp;&nbsp;|&nbsp;`|-MepLbEntry`<br/>
+&nbsp;&nbsp;&nbsp;|&nbsp;`|-MepLtEntry`<br/>
+&nbsp;&nbsp;&nbsp;|&nbsp;|&nbsp;`|-MepLtTransactionEntry*`<br/>
+&nbsp;&nbsp;&nbsp;|&nbsp;|&nbsp;`|-MepLtReply*`<br/>
+&nbsp;&nbsp;&nbsp;|&nbsp;|&nbsp;`|-SenderIdTlv`<br/>
+&nbsp;&nbsp;&nbsp;|&nbsp;`|-DelayMeasurement*` (SOAM)<br/>
+&nbsp;&nbsp;&nbsp;|&nbsp;|&nbsp;`|-DmId`<br/>
+&nbsp;&nbsp;&nbsp;|&nbsp;|&nbsp;`|-DelayMeasurement-Stat-Current`<br/>
+&nbsp;&nbsp;&nbsp;|&nbsp;|&nbsp;|`-DelayMeasurement-Stat-History*`<br/>
+&nbsp;&nbsp;&nbsp;|&nbsp;|`-LossMeasurement*` (SOAM)<br/>
+&nbsp;&nbsp;&nbsp;|&nbsp;|&nbsp;`|-LmId`<br/>
+&nbsp;&nbsp;&nbsp;|&nbsp;|&nbsp;`|-LossMeasurement-Stat-Current`<br/>
+&nbsp;&nbsp;&nbsp;|&nbsp;|&nbsp;`|-LossMeasurement-Stat-History*`<br/>
+&nbsp;&nbsp;&nbsp;|&nbsp;`|-RemoteMepEntry*`<br/>
+&nbsp;&nbsp;&nbsp;|&nbsp;`|-MepId`<br/>
+&nbsp;&nbsp;&nbsp;`|-RemoteMepId`<br/>
+
+
+The classes and interfaces can be broken down into 4 main categories:
+* Those used as identifiers
+* Those for configuring the object
+* Those representing both the status attributes of the object and its 
+configuration (usually ending in Entry)
+* Those used in commands called on objects - for Loopback, Linktrace, Delay and 
+Loss Measurement these are not configured - they are called as a method with 
+parameters
+
+
+# Java Services
+A set of services are defined for managing the object model
+* CFM MD Service
+* CFM MEP Service
+* SOAM Service
+
+## CFM MD Service
+This is an interface that manages only the configuration of Maintenance Domain 
+and Maintenance Association. It acts as a standalone service in ONOS that manages 
+only these 2 levels of the model. The Maintenance Domain contains a list of 
+Maintenance Associations does not contain Meps - these are left to the CfmMepService.
+
+These objects are persisted in ONOS in a distributed data store by this service.
+
+There are CLI commands for creating, deleting and modifying these objects.
+* cfm-md-list-all - Lists all CFM Maintenance Domains.
+* cfm-md-list - Lists a single CFM Maintenance Domain.
+* cfm-md-add - Add a CFM Maintenance Domain.
+* cfm-md-delete - Delete a CFM Maintenance Domain and its children.
+* cfm-ma-add - Add a CFM Maintenance Association to a Maintenance Domain.
+* cfm-ma-delete - Delete a CFM Maintenance Association and its children.
+
+## CFM MEP Service
+This is an interface that manages the MEP and objects and commands below it. A 
+MEP managed under this service has a reference to the Maintenance Domain and 
+Maintenance Association above it.
+
+MEPs are identified by a combination of MdId, MaID and MepId.
+
+The service has the following actions associated with it
+* Create MEP
+* Delete MEP
+* Get all MEPs (for a particular MD and MA)
+* Get individual MEP
+* Transmit Loopback
+* Abort Loopback
+* Transmit Linktrace
+* Create Test Signal
+* Abort Test Signal
+
+At the moment the MEP object is only maintained in memory and not persisted in 
+the ONOS data store. The objects Loopback, Linktrace, Test Signal, Loss 
+Measurement and Delay Measurement are not maintained in ONOS at all as they are 
+not really configuration objects. They are called on the fly and are passed down 
+as a collection of method parameters to the device implementing the MEP. This 
+device will operate on them and their results can be obtained by querying the 
+responsible MEP on the device. For instance the results of LinkTrace, Loopback 
+and Test Signal will appear in the MepLbEntry, MepLbEntry and MepTsEntry under 
+the MepEntry when the “Get Individual Mep” method is called.
+
+See in
+* apps/cfm/src/test/resources/examples
+
+for some JSON examples that can be used to activate this functionality.
