Charles Chan1d337652019-09-08 12:02:27 -0700[diff] [blame]9Trellis is an **open-source multi-purpose L2/L3 leaf-spine switching fabric**.
Zack Williamsd63d35b2020-06-23 14:12:46 -0700[diff] [blame]10
11The development of Trellis over the last four years has been influenced by
12three core trends in the networking industry:
Charles Chan1d337652019-09-08 12:02:27 -0700[diff] [blame]13
14- First, **Trellis is built using bare-metal switches with merchant-silicon ASICs**.
15 Instead of using OEM networking hardware, Trellis uses hardware directly from ODMs.
Charles Chan1d337652019-09-08 12:02:27 -0700[diff] [blame]16
Zack Williamsd63d35b2020-06-23 14:12:46 -0700[diff] [blame]17 The trend of using bare-metal (white-box) switches is unmistakable in the
18 networking industry today, spurred by the massive bandwidth-density and
19 growing sophistication of merchant silicon ASICs.
20
21 Production quality Trellis today is based on EdgeCore switches with Broadcom
22 Trident2, Tomahawk and Qumran switch ASICs. The Trellis team continues to
23 work towards including more ODMs and merchant silicon vendors.
24
25- Second, **Trellis is based on SDN principles**, to provide simpler, more
26 flexible and easily customizable networks. By externalizing the network’s
27 control, management functions and policy decisions in the ONOS SDN
28 controller, Trellis provides network operators with a number of SDN benefits
29 compared to traditional box-embedded network control. These include
30 centralized configuration, automation, operation and troubleshooting.
Charles Chan1d337652019-09-08 12:02:27 -0700[diff] [blame]31
32- Third, **Trellis is open-source**.
Zack Williamsd63d35b2020-06-23 14:12:46 -0700[diff] [blame]33 The networking industry has seen an explosion of open source projects, and
34 network operators have been eager to embrace open-source solutions. Trellis
35 allows operators unparalleled ability to customize Trellis for their
36 application, integrate with the rest of their systems, add features and APIs
37 themselves and not be beholden to a traditional vendor’s timelines and
38 prices. An absence of commercial licenses lowers the bar for anyone to try
39 out Trellis.
Charles Chan1d337652019-09-08 12:02:27 -0700[diff] [blame]40
Zack Williamsd63d35b2020-06-23 14:12:46 -0700[diff] [blame]41Together, all three attributes of Trellis considerably lower the Total Cost of
42Ownership (TCO) for operators who plan to run it in production.
