The difference of hardware

In Beluganos, some features are supported only specific hardware because of some limitations. For example, there is some specification difference between OF-DPA and OpenNSL which is a open ASIC API provided by Broadcom. In this document, supported feature is described for each API.

Moreover, x86 OFSwitch (OpenFlow switch) is also supported by Beluganos. From this perspective, Lagopus is used for verification. In OFSwitch, almost all supported feature is same as OF-DPA, but there is some difference.

Following table shows that our verification environments.

Type OF-DPA OFSwitch OpenNSL
Trident+ Verified - No
Trident II Verified - Verified
Trident II+ Verified - Verified
Trident III No - Planned
Tomahawk No - Verified
Tomahawk II No - TBD
DNX series No - Planned
x86 - Verified -
