This is a maintenance release in the Napatech Link-Inline Software 3.0 series (see features below): This release updates the FPGA image relevant to the 3.0 series:
NOTE: Only this version of the FPGA image is supported by this release
This release resolves these Support issues compared to previous maintenance release:
- Support-ID 45232: Question on which kind of flow rules are able to be created in same group
- Support-ID 45123: nt_examples should not be part of DPDK examples
- Support-ID 45225: GTP encapsulated ICMP traffic only forwarded if plain GTP has been sent before
This release also adds support for this feature:
- Support for pattern match on ethertype
Features in introduced in the Napatech Link-Inline Software 3.0.0:
- Support for 2x100G port speed on NT200A02 (FPGA image 9563-55-16) with Native DPDK driver (version 22.11.1) with support for the following features
- Flow lookup (based on Flow Matcher)
- Policy lookup and enforcement (based on leaky bucket algorithm)
- Support for up to 4 policies
- MBR Policing support
- IPv4 and IPv6 support
- Flow mirroring support
- Subnet filtering (E.g. Can be used for subnet filtering on a per gNB basis in a 5G networks)
- Scatter-gather buffer system – to improve packet latency through the slow path (all packets going to the host system)
- GTP de-/en-capsulation
- NAT support (IPv4 only)
- DSCP tagging support
- Billing Counters
- Kubernetes support using Napatech Device Plugin
- VFs and support for connecting to VFs through Kubernetes containers
- rte_flow configuration through remote app that access PFs thought Linux sockets
- Inline UPF Demo application
- Limited features in this release
- Reduced Flow learning rate (in the 150k/s range)
