+SD-Fabric 1.0.0
+===============
+
+This is the first release of SD-Fabric.
+
+SD-Fabric is an open source, full stack, deeply programmable network fabric optimized for edge cloud,
+5G, and Industry 4.0 applications.
+It builds on SDN and cloud native principles to create a disruptive platform that for the first time
+empowers the network with modern cloud development principles.
+
+- **Right-sized Topology**: Scale from a single Top-of-Rack (ToR) switch, to an
+  Highly-Available (HA) setup with paired ToRs, to a full leaf-spine fabric
+  for multi-rack deployments.
+- **API Driven**: Well-defined APIs provide the ability to drop or reroute traffic,
+  create slices with configurable QoS, obtain telemetry, and more.
+- **Cloud Managed**: Fully integrated and configured by Aether™ Management Platform.
+- **5G as a Workload**: Reduce CPU load and increase performance by terminating GTP-U tunnels
+  directly in the fabric switches, with QoS and slicing support.
+- **End-to-End Visibility**: With Inband Network Telemetry (INT) on switches and end hosts,
+  enabling closed loop control applications.
+
+Feature Highlights
+-------------------
+- **Fabric connectivity**
+
+  - Support single switch, paired-leaves with dual-homing, and leaf-spine topology
+  - Bridging, IPv4 routing, ECMP, DHCP relay
+  - Redundancy on both control and data plane
+
+- :ref:`Switch-based P4-UPF <p4_upf>`
+
+  - 4G/5G UPF implemented with P4 programmable switches
+  - Support downlink buffering for UE idle-mode and handover via microservice
+  - Integration with PFCP standard interface
+
+- :ref:`Slicing and QoS <slicing_qos>`
+
+  - Data plane support for fabric-wide slicing and QoS using dedicated hardware queues
+  - Control plane integration with SD-Core for UPF QoS with single slice (multiple slices in the next release)
+  - REST APIs for classification of non-mobile traffic
+
+- :ref:`Inband Network Telemetry (INT) <int>`
+
+  - INT-XD mode compliant with Telemetry Report Specification v0.5
+  - Integrated with Intel DeepInsight
+  - Switch INT
+
+    - Support for flow, drop, and queue congestion reports
+    - Watchlist and smart filters to reduce the volume of reports
+    - Integration with P4-UPF
+
+  - Host INT
+
+    - Experimental implementation based on eBPF
+    - Kubernetes CNI-independent, tested with Cilium and Calico
+    - Support for flow and drop reports
+
+- **API**
+
+  - Drop traffic
+  - Pin traffic to specific spine (in a leaf-spine setup)
+  - Slicing and QoS for non-mobile traffic
+
+- **Scalability**
+
+  - 5K UEs, 10 calls per second with 1 CPU core and 4G RAM per ONOS instance
+
+
+Deployment
+----------
+- Support Kubernetes deployments with Helm charts
+- Logging integration via EFK
+- Monitoring integration via Prometheus/Grafana
+- Alarm integration via Kibana
+
+
+Testing
+-------
+- **Data plane tests**
+
+  - Unary tests based on PTF framework (running pre-merge on Tofino model)
+  - Line rate test based on PTF framework and TRex traffic generator for INT and QoS features
+    (running nightly on hardware switch)
+
+- **Control plane tests**
+
+  - UP4 integration with PFCP Agent based on ONOS STC framework for 2x2 and paired-leaves topologies
+    (running pre-merge)
+
+- **System tests**
+
+  - Based on TestON framework
+  - Running nightly on paired-leaves and 2x2 topology with 3 ONOS instances
+  - Features covered:
+
+      - Bridging
+      - Paired-leaves
+      - UP4
+      - INT with DeepInsight integration
+      - QoS (both mobile and non-mobile traffic)
+
+  - Jenkins dashboard showing nightly results
+
+Known Issues and Limitations
+----------------------------
+- `SDFAB-653 <https://jira.opennetworking.org/browse/SDFAB-653>`_
+
+   ArpHandler is unable to handle ARP requests for device loopback address
+- `SDFAB-655 <https://jira.opennetworking.org/browse/SDFAB-655>`_
+
+   UP4 reconciliation cycle can leave switch flow state inconsistent causing UE
+   data traffic to be dropped. Requires to detach and re-attach UEs.
+- Host INT features assumes the fabric interface on each K8s worker node uses the same name
