+
+Trellis is an **open-source multi-purpose L2/L3 leaf-spine switching fabric**.
+The development of Trellis over the last four years has been influenced by three core trends in the networking industry:
+
+- First, **Trellis is built using bare-metal switches with merchant-silicon ASICs**.
+  Instead of using OEM networking hardware, Trellis uses hardware directly from ODMs.
+  The trend of using bare-metal (white-box) switches is unmistakable in the networking industry today, spurred by the massive bandwidth-density and growing sophistication of merchant silicon ASICs.
+  Production quality Trellis today is based on EdgeCore switches with Broadcom Trident2, Tomahawk and Qumran switch ASICs.
+  The Trellis team continues to work towards including more ODMs and merchant silicon vendors.
+
+- Second, **Trellis is based on SDN principles**, to provide simpler, more flexible and easily customizable networks.
+  By externalizing the network’s control, management functions and policy decisions in the ONOS SDN controller,
+  Trellis provides network operators with a number of SDN benefits compared to traditional box-embedded network control.
+  These include centralized configuration, automation, operation and troubleshooting.
+
+- Third, **Trellis is open-source**.
+  The networking industry has seen an explosion of open source projects, and network operators have been eager to embrace open-source solutions.
+  Trellis allows operators unparalleled ability to customize Trellis for their application, integrate with the rest of their systems,
+  add features and APIs themselves and not be beholden to a traditional vendor’s timelines and prices.
+  An absence of commercial licenses lowers the bar for anyone to try out Trellis.
+
+Together, all three attributes of Trellis considerably lower the Total Cost of Ownership (TCO) for operators who plan to run it in production.
+
+
+Highlights
+==========
+- Classic-SDN Control with ONOS to directly program ASIC forwarding tables in bare metal switches with merchant silicon
+- L2 forwarding (Bridging) within server-racks and L3 forwarding (Routing) across racks
+- MPLS Segment routing for better scale and reduced programming
+- Control plane functionality with Trellis vRouter for external connectivity
+- N-way redundancy and tier-1 telecom operator scale
+- Support for different use cases ranging from Central Office to backhaul in operator networks
+- Single-pane-of-glass monitoring and troubleshooting with ONOS
+- CapEx and OpEx savings with white-box hardware and open source software
+- Future Proof: P4 and Stratum integration to unlock advanced capabilities
