OcNOS x Broadcom merchant silicon

The Broadcom silicon behind your OcNOS switches and routers

Two Broadcom families power open networking. IP Infusion turns them into complete, supported systems: OcNOS-DC on the Tomahawk and Trident Ethernet fabrics, and OcNOS-SP on the deep-buffer Jericho and Qumran routers. Here is how the families differ, the generations and their advantages, and the qualified boxes you can buy today.

The two families

How Broadcom's silicon families differ

StrataXGS (Tomahawk, Trident) uses a shallow on-chip shared buffer for speed and high radix; StrataDNX (Jericho, Qumran) uses a deep HBM buffer with VOQ scheduling for scale and lossless routing. One choice drives almost everything: where the packet buffer lives.

StrataXGSOcNOS-DC
Tomahawk & Trident

Shallow buffer, high radix, low latency. A shared on-chip SRAM pool absorbs microbursts while a programmable pipeline forwards at line rate. This is the switch line for data-center and AI scale-out fabrics.

StrataDNXOcNOS-SP
Jericho, Qumran & Ramon

Deep HBM buffer, VOQ scheduling, cell fabric. Gigabytes of in-package HBM plus a credit-scheduled fabric give near-perfect load balancing and internet-scale routing. This is the router line for carrier core, edge and DCI.

Rule of thumb

Choose XGS when you need speed, radix and low latency for a switching fabric. Choose DNX when you need deep buffers, huge route tables and scheduled routing. No Tomahawk or Trident has HBM, and on DNX the route table lives in external TCAM, separate from the HBM buffer.

Generations

Each generation, and what it buys you

Every generation roughly doubles bandwidth. These are the four tracks IP Infusion builds on, newest capability on the right.

FAQ

Questions engineers actually ask

StrataXGS (Tomahawk, Trident) uses a shallow on-chip shared buffer with a high-radix, low-latency pipeline: it is the workhorse for data-center and AI scale-out leaf/spine fabrics. StrataDNX (Jericho, Qumran, Ramon) uses a deep in-package HBM buffer with virtual-output-queue (VOQ) scheduling and, in Jericho, a credit-based cell fabric: it is built for carrier core/edge routing, deep-buffer DCI, and lossless AI scale-out via a Distributed Disaggregated Chassis (DDC). Rule of thumb: XGS = shallow buffer, speed and radix; DNX = deep buffer, scale and scheduling.
No. Every Tomahawk and Trident part is a shallow on-chip shared-buffer switch (tens to low-hundreds of MB of SRAM), with no HBM. Deep buffering via in-package HBM is a StrataDNX property (Jericho and Qumran). If a design needs to absorb sustained congestion or long cross-DC flows, that is a deep-buffer DNX job, not a Tomahawk job.
Three roles. Scale-out (leaf/spine inside a data center): Tomahawk 5 and Tomahawk 6 on the XGS side, or Jericho3-AI plus Ramon3 (a deep-buffer scheduled DDC) on the DNX side. Scale-up (XPU-to-XPU inside a rack): Tomahawk Ultra and Tomahawk 6 with Broadcom Scale-Up Ethernet. Scale-across (between data centers): Jericho4 with Ramon4. OcNOS-DC runs the Ethernet scale-out fabrics on validated open hardware.
The 12.8 Tbps, 32x400G Trident 4 is BCM56880 (Trident4-X11). BCM56780 is a separate, lower-capacity 8.0 Tbps Trident 4 variant with integrated MACsec/IPsec and cannot do 32x400G. Keep the two distinct.
Tomahawk 6 (BCM78910 / BCM78914) is the world's first single-chip 102.4 Tbps switch, built on TSMC 3nm, for both scale-out and scale-up AI fabrics; a co-packaged-optics variant (Tomahawk 6-Davisson, BCM78919) ships with integrated silicon photonics. Tomahawk Ultra (BCM78920) is a 51.2 Tbps scale-up chip with 250ns latency, in-network collectives, and link-layer retry for lossless XPU-to-XPU Ethernet, positioned against InfiniBand and NVLink.
OcNOS is validated across Broadcom StrataXGS (Trident 3 and 4, Tomahawk 2 through 5) and StrataDNX (Qumran 2a, 2c, 2c+ and 2u, Jericho2c+) on open hardware from Edgecore, UfiSpace, and others. The authoritative list is the OcNOS Hardware Compatibility List. OcNOS-DC targets the DC/AI Ethernet fabrics; OcNOS-SP targets the deep-buffer routing platforms.
A DDC replaces a traditional chassis router with separate 1RU/2RU boxes: Jericho line cards and Ramon fabric elements, wired as a scheduled cell fabric. Because the fabric is credit-scheduled and cell-based (not ECMP-hashed), it delivers perfect load balancing and no hash-collision hot spots, which is why it is attractive for both carrier scale and lossless AI back-end fabrics.
Tomahawk 6 (BCM78910 / BCM78914) roughly doubles Tomahawk 5: 102.4 Tbps versus 51.2 Tbps, on TSMC 3nm versus 5nm, with 1.6T-capable ports and configurable 100G or 200G SerDes. Tomahawk 5 is the current 800G AI scale-out workhorse; Tomahawk 6 is the first single-chip 102.4T switch and handles both scale-out (Clos) and scale-up fabrics. Both are shallow shared-buffer StrataXGS switches with no HBM.
Both are StrataXGS shallow shared-buffer switches. Tomahawk is the high-radix, latency-optimized line for hyperscale spine and AI scale-out (Tomahawk 5, Tomahawk 6). Trident is the more deeply programmable, feature-rich line for the data-center leaf and edge (Trident 3, Trident 4). Choose Tomahawk for raw speed and radix, Trident for programmability and richer features at a lower cost per port.
Both are StrataDNX deep-buffer routers with in-package HBM and VOQ scheduling. Jericho is the higher-capacity switch-router used as a line card in a Distributed Disaggregated Chassis (DDC) with Ramon fabric elements (Jericho2c+, Jericho3-AI). Qumran is single-chip and needs no separate fabric, covering compact edge, aggregation, DCI, and access routing (Qumran2a, Qumran2c, Qumran3D, and the Qumran-UX, AX and MX access family). Use Jericho for scale-out chassis-class routing, Qumran for self-contained edge and access boxes.
Merchant silicon is off-the-shelf switch and router ASICs, such as Broadcom StrataXGS and StrataDNX, that any hardware maker can build a system on, as opposed to custom in-house chips. It is what makes open networking possible: the same Broadcom chip appears in boxes from Edgecore, UfiSpace, Celestica and others, and IP Infusion runs one OcNOS image across them, so you choose the hardware without being locked to a single vendor stack.
One NOS across the portfolio

Pick the silicon. We ship the complete system.

A merchant ASIC is half a router. OcNOS turns Broadcom silicon into a complete, supported switch or router on open hardware you choose, from Edgecore, UfiSpace and Celestica. The Hardware Compatibility List is the source of truth: if a box is not on the HCL, it is not a validated OcNOS target.
