1. Platform Overview
The RtBrick FullStack (RBFS) software runs as a LXC container on a Linux host operating system in the Edgecore switches, which are capable of Layer 2 and Layer 3 switching. Multiple switches can be combined to support several subscribers using a leaf and spine architecture or deployed as a standalone using the consolidated BNG approach. Additionally, the ZTP (Zero-Touch-Provisioning) and REST-based APIs that expose the state of the system are also supported.
The image below shows a high-level overview of the platform architecture.
The platform consists of hardware based on forwarding ASIC and host operating system based on Open Network Linux (ONL). An RBFS container that resides on top of this software includes all necessary packages to deliver access and routing protocols.
This guide looks at the platform features, the different supported hardware platforms, and features that are supported on each hardware platform.
1.1. Supported Platforms
RtBrick’s software has been validated on the following hardware platforms.
-
Edgecore AS7316-26XB
-
Edgecore AS5916-54XKS
1.2. Brick Daemon (BD)
RBFS runs multiple Brick Daemons (BD). Every application that runs within RBFS is fundamentally a brick daemon. For example, forwarding daemon (fibd), configuration daemon (confd), BGP (bgp.iod or bgp.appd), or interface management daemon (ifmd).
1.2.1. Brick Daemon (BD) Restartability
If a brick daemon fails (for a limited number of times), RBFS will restart it automatically. If the automatic restart does not succeed, you can use the Ubuntu system control to start a daemon.
For more information about troubleshooting the Brick Daemons, see section "2.2. Brick Daemons" of the RBFS NOC Troubleshooting Guide.
2. RBFS on Edgecore AS7316-26XB Platform
RtBricks' open BNG software running as a Consolidated BNG, that provides full BNG functionality on an EdgeCore AS7316-26XB based on a Broadcom QAX chip, which is suitable for deployments in low-density areas and hardened platforms at cell-sites.
The Edgecore AS7316-26XB is an open design cell site gateway platform that provides a combination of 1/10 Gbps, 25 Gbps, and 100 Gbps interfaces, utilizing merchant silicon and an x86 processor with optimized performance for service provider access and aggregation networks.
2.1. Switch Silicon: Broadcom Qumran-AX BCM88470
Broadcom Qumran-AX BCM88470 platform which is delivered on a single 1RU device provides a Consolidated BNG. The QAX platform has a lower form factor chipset from Broadcom Jericho-1 family.

3. RBFS on Edgecore AS5916-54XKS Platform
RtBricks' open BNG software running as a spine-leaf architecture, that provides full BNG functionality on an EdgeCore AS5916-54XKS based on a Broadcom QMX chip. RtBrick supports spine as well access-leaf images for the AS5916-54XKS platform.
The Edgecore AS5916-54XKS is based on Broadcom StrataDNX Qumran MX switch silicon, capable of line-rate 800 Gbps Layer 2 and Layer 3 switching. The switch can be deployed either as a top-of-rack switch in a data center, or as a carrier access/aggregation switch, and edge router.
3.1. Switch Silicon: Broadcom Qumran-MX BCM88375
Broadcom Qumran-MX BCM88375 platform can help build fixed form factor, feature-rich, deep-buffered switches to enable cloud-scale networking and Carrier network applications. The BCM88375 device processes up to 800 Gbps traffic, supporting up to six 100G full-duplex ports at Layer 2 through Layer 4 with integrated deep-buffer traffic management capabilities, and a fabric interface.
