This is a maintenance release 12.2.3 of the Napatech Link Capture 12.2 software, resolving a performance issue on the Windows platform.

The Napatech Link™ Capture 12.2 software release series, introduces powerful features for test & measurement applications. Nanosecond hardware transmit and receive timestamping enables precision network roundtrip delay and jitter measurements. The solution also includes advanced features for error and network jitter simulation. All of this is supported for 10G, 25G, 40G and 100G network speeds. The release also includes support for Cisco FabricPath encapsulation and bug-fix’es. Please refer to the documentation and release notes for details on the new features, bugfix’es and which SmartNIC products the new features apply to.
