+# Fabric Crossconnect Service
+
+The Fabric Crossconnect service creates an L2 bridge between two given ports on the same device. For example, this service can be used on a SEBA pod to connect OLT devices to a BNG via the aggregation switch.
+
+A fabric crossconnect entry is a tuple (`deviceid`, `vlanid`, `port1`, `port2`).
+
+For more information, see [VLAN Cross Connect](https://wiki.opencord.org/display/CORD/VLAN+Cross+Connect)
+
+## Models
+
+This service is comprised of three models:
+
+- `FabricCrossconnectService` global service-related parameters, such as the name of the service. There is currently no additional state here beyond the default `XOS` `Service` model.
+- `FabricCrossconnectServiceInstance` represents one half of a vlan crossconnect. Fields include the following:
+ - `s-tag` the vlan_id that will be connected
+ - `switch_datapath_id` switch id where the vlan crossconnect will be enacted
+ - `source_port` port number on the switch
+- `BNGPortMapping` represents the other half of a vlan crossconnect. Fields include the following:
+ - `s_tag` the vlan_id that will be connected. In addition to specifying a single vlan_id, the keyword `ANY` may be used, or a range (`123-456`) may be used.
+ - `switch_port` port number on the switch
+
+`FabricCrossconnectServiceInstance` and `BNGPortMapping` work together to create the vlan crossconnect tuple, linked by a common `s-tag`.
+
+### Example TOSCA
+
+Below is an example TOSCA recipe that creates a `FabricCrossconnectServiceInstance`:
+
+```yaml
+tosca_definitions_version: tosca_simple_yaml_1_0
+imports:
+ - custom_types/fabriccrossconnectservice.yaml
+ - custom_types/fabriccrossconnectserviceinstance.yaml
+description: Create a FabricCrossconnectServiceInstance
+topology_template:
+ node_templates:
+ service#fabric-crossconnect:
+ type: tosca.nodes.FabricCrossconnectService
+ properties:
+ name: fabric-crossconnect
+ must-exist: true
+
+ fcsi:
+ type: tosca.nodes.FabricCrossconnectServiceInstance
+ properties:
+ name: "custom_vm_crossconnect"
+ s_tag: 123
+ source_port: 3
+ switch_datapath_id: "of:0000000000000201"
+ requirements:
+ - owner:
+ node: service#fabric-crossconnect
+ relationship: tosca.relationships.BelongsToOne
+```
+
+Below is an example TOSCA recipe that creates a `BNGPortMapping` for a single s-tag:
+
+```yaml
+tosca_definitions_version: tosca_simple_yaml_1_0
+imports:
+ - custom_types/bngportmapping.yaml
+description: Create a bng port mapping
+topology_template:
+ node_templates:
+ bngmapping:
+ type: tosca.nodes.BNGPortMapping
+ properties:
+ s_tag: "222"
+ switch_port: 4
+```
+
+## Integration with other Services
+
+The western neighbor of the `FabricCrossconnectService` is typically an access service such as `VOLTService`. `FabricCrossconnectServiceInstance` participates in the dataplane chain for a given subscriber.
+
+`FabricCrossConnectService` features a method `acquire_service_instance(subscriber_service_instance)` that may be used as a helper for creating service instances. Given that many subscribers may map to a single `s_tag`, it's often the case that a single `FabricCrossconnectServiceInstance` is used by several subscribers. `acquire_service_instance` does the following:
+
+1) Check to see if an eligible `FabricCrossconnnectServiceInstance` already exists, and if so links it to the subscriber_service_instance.
+2) If no eligible `FabricCrossconnectServiceInstance` already exists, then a new one will be created and linked.
+
+## Synchronization workflow
+
+### FabricCrossconnectServiceInstance
+
+When a `FabricCrossconnectServiceInstance` is created, updated, or deleted, the synchronizer will make a REST API call to ONOS.
+
+### BNGPortMapping
+
+No specific processing is performed if a `BNGPortMapping` is created, updated, or deleted, as the workflow is driven by `FabricCrossconnectServiceInstance`. Responding to changes in `BNGPortMapping` is future work. For now it is suggested that if you need to change one, afterward you touch any `FabricCrossconnectServiceInstance` that may be affected, causing them to resynchronize.
