Link™ NT200A02 SmartNIC Features
Full line-rate packet capture
Multi-port packet sequence
Multi-port packet sequence and merge
Napatech FPGA SmartNICs typically provide multiple ports. Ports are usually paired, with one port receiving upstream packets and another port receiving downstream packets. Since these two flows going in different directions need to be analyzed as one, packets from both ports must be merged into a single analysis stream. Napatech FPGA SmartNICs can sequence and merge packets received on multiple ports in hardware using the precise time stamps of each Ethernet frame. This is highly efficient and offloads a significant and costly task from the analysis application.
There is a growing need for analysis appliances that are able to monitor and analyze multiple points in the network, and even provide a network-wide view of what is happening. Not only does this require multiple FPGA SmartNICs to be installed in a single appliance, but it also requires that the analysis data from all ports on every accelerator be correlated.
With the Napatech Software Suite, it is possible to sequence and merge the analysis data from multiple FPGA SmartNICs into a single analysis stream. The merging is based on the nanosecond precision time stamps of each Ethernet frame, allowing a time-ordered merge of individual data streams.
Intelligent Multi-CPU distribution
Modern servers provide unprecedented processing power with multi-core CPU implementations. This makes standard servers an ideal platform for appliance development. But, to fully harness the processing power of modern servers, it is important that the analysis application is multi-threaded and that the right Ethernet frames are provided to the right CPU core for processing. Not only that, but the frames must be provided at the right time to ensure that analysis can be performed in real time.
Napatech Multi-CPU distribution is built and optimized from our extensive knowledge of server architecture, as well as real life experience from our customers.
Napatech FPGA SmartNICs ensure that identified flows of related Ethernet frames are distributed in an optimal way to the available CPU cores. This ensures that the processing load is balanced across the available processing resources, and that the right frames are being processed by the right CPU cores.
With flow distribution to multiple CPU cores, the throughput performance of the analysis application can be increased linearly with the number of cores, up to 128. Not only that, but the performance can also be scaled by faster processing cores. This highly flexible mechanism enables many different ways of designing a solution and provides the ability to optimize for cost and/or performance.
Napatech FPGA SmartNICs support different distribution schemes that are fully configurable:
- Distribution per port: all frames captured on a physical port are transferred to the same CPU or a range of CPU cores for processing
- Distribution per traffic type: frames of the same protocol type are transferred to the same CPU or a range of CPU cores for processing
- Distribution by flows: frames with the same hash value are sent to the same CPU or a range of CPU cores for processing
- Combinations of the above

Optimum Cache Utilization
On-Board Packet Buffering
Napatech FPGA SmartNICs provide on-board memory for buffering of Ethernet frames. Buffering assures guaranteed delivery of data, even when there is congestion in the delivery of data to the application. There are three potential sources of congestion: the PCI interface, the server platform, and the analysis application.
PCI interfaces provide a fixed bandwidth for transfer of data from the SmartNIC to the application. This limits the amount of data that can be continuously transferred from the network to the application. For example, a 16-lane PCIe Gen3 interface can transfer up to 115 Gbps of data to the application. If the network speed is 2×100 Gbps, a burst of data cannot be transferred over the PCIe Gen3 interface in real time, since the data rate is twice the maximum PCIe bandwidth. In this case, the onboard packet buffering on the Napatech SmartNIC can absorb the burst and ensure that none of the data is lost, allowing the frames to be transferred once the burst has passed.
Servers and applications can be configured in such a way that congestion can occur in the server infrastructure or in the application itself. The CPU cores can be busy processing or retrieving data from remote caches and memory locations, which means that new Ethernet frames cannot be transferred from the SmartNIC.
In addition, the application can be configured with only one or a few processing threads, which can result in the application being overloaded, meaning that new Ethernet frames cannot be transferred. With onboard packet buffering, the Ethernet frames can be delayed until the server or the application is ready to accept them. This ensures that no Ethernet frames are lost and that all the data is made available for analysis when needed.
IP fragment handling
IP fragmentation occurs when larger Ethernet frames need to be broken into several fragments in order to be transmitted across the network. This can be due to limitations in certain parts of the network, typically when GTP tunneling protocols are used. Fragmented frames are a challenge for analysis applications, as all fragments must be identified and potentially reassembled before analysis can be performed. Napatech FPGA SmartNICs can identify fragments of the same frame and ensure that these are associated and sent to the same CPU core for processing. This significantly reduces the processing burden for analysis applications.
In-line application support
The Napatech SmartNIC family supports 40 Gbps in-line applications enabling customers to create powerful, yet flexible in-line solutions on standard servers. The more CPU-demanding the application is, and the higher the speeds of links, the higher the value of this solution. Features include:
- Full throughput bidirectional Rx/Tx up to 40G link speed for any packet size
- Multi-core processing support with up to 128 Rx/Tx streams per accelerator
- Customizable hash-based load distribution
- Efficient zero copy roundtrip from Rx to Tx
- Single bit flip selection to discard or forward each individual packet
- Typical 50 us roundtrip latency from Rx to Tx fiber
For network security purposes, different traffic scenarios need to be recreated and simulated to toughen the infrastructure. The packets also need to be replayed to understand delays and disruptions caused by traffic bursts/peaks to improve Quality of Service (QoS). With Napatech FPGA SmartNICs, it is easy to setup and specify the test scenario to replay the same PCAP files from real network events at 40G and 100G link speeds.
Access control and authentication solutions can now implement full line rate solutions, that can cope with small packets, with a SmartNIC that does robust packet delivery at high network loads. Session control propels traffic in and out of the SmartNIC, at low latency (<5us), while simultaneously copying a subset to the host CPU for analysis. With the session control feature, inline use cases can benefit from low latency at speeds 1-100G.
Get highest precision timestamping for traffic that needs to be redistributed to multiple network devices. Napatech FPGA SmartNICs systems can forward and/or split traffic captured on a single tapping point to a cluster of servers for processing, without using additional equipment. This is achieved by the Napatech FPGA SmartNICs acting as both Smart Taps and packet capture devices and is apt for multi-box solutions with single tapping points. This feature eliminates the need to implement expensive SmartTaps, time stamping switches, packet brokers and other time sync components.
