FULL LINE-RATE PACKET CAPTURE
 
Napatech accelerators are highly optimized to capture network traffic at full line-rate, with almost no CPU load on the host server, for all frame sizes. Zero-loss packet capture is critical for applications that need to analyze all the network traffic. If anything needs to be discarded, it is a matter of choice by the application, not a limitation of the accelerator.
 
Standard network interface cards (NICs) are not designed for analysis applications where all traffic on a connection or link needs to be analyzed. NICs are designed for communication where data that is not addressed to the sender or receiver is simply discarded. This means that NICs are not designed to have the capacity to handle the amount of data that is regularly transmitted in bursts on Ethernet connections. In these burst situations, all of the bandwidth of a connection is used, requiring the capacity to analyze all Ethernet frames. Napatech accelerators are designed specifically for this task and provide the maximum theoretical packet capture capacity.
OPTIMIZED PACKET BUFFERS
 
Napatech accelerators use a buffering strategy that allocates a number of large memory buffers where as many packets as possible are placed back-to-back in each buffer.  Using this implementation, only the first access to a packet in the buffer is affected by the access time to external memory. Thanks to cache pre-fetch, the subsequent packets are already in the level 1 cache before the CPU needs them. As hundreds or even thousands of packets can be placed in a buffer, a very high CPU cache performance can be achieved leading to application acceleration.
 
Buffer configuration can have a dramatic effect on the performance of analysis applications. Different applications have different requirements when it comes to latency or processing. It is therefore extremely important that the number and size of buffers can be optimized for the given application. Napatech accelerators make this possible. 
 
The flexible server buffer structure supported by Napatech accelerators can be optimized for different application requirements. For example, applications needing short latency can have frames delivered in small chunks, optionally with a fixed maximum latency. Applications without latency requirements can have data delivered in large chunks, providing more effective server CPU processing of the data. Applications that have intensive, time-consuming processing requirements can configure larger server buffers (up to 128 GB).
 
Up to 128 buffers can be configured and combined with Napatech multi-CPU distribution (see “Multi-CPU distribution”).
 
ON-BOARD PACKET BUFFERING
 
Napatech accelerators provide on-board memory for buffering of Ethernet frames. Buffering assures guaranteed delivery of data, even when there is congestion. 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 accelerator to the application. For some accelerators, this can limit the amount of data that can be transferred from the network to the application. For example, an 8-lane PCIe Gen3 interface can transfer up to 50 Gbps of data to the application. If the network speed is 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 transferable rate that can be transferred over the PCIe Gen3 interface. In this case, the onboard packet buffering on the Napatech accelerator 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 accelerator.
 
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.
MULTI-PORT PACKET MERGE
 
Napatech accelerators 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 accelerators can 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 accelerators 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 merge the analysis data from multiple accelerators 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.
 
HARDWARE TIME STAMP
 
The ability to establish the precise time when frames have been captured is critical to many applications. 
 
To achieve this, all Napatech accelerators are capable of providing a high-precision time stamp, sampled with 4 nanosecond resolution, for every frame captured and transmitted.
 
At 10 Gbps, an Ethernet frame can be received and transmitted every 67 nanoseconds. At 100 Gbps, this time is reduced to 6.7 nanoseconds. This makes nanosecond-precision time-stamping essential for uniquely identifying when a frame is received. This incredible precision also enables you to merge frames from multiple ports on multiple accelerators into a single, time-ordered analysis stream.
 
In order to work smoothly in the different operating systems supported, Napatech accelerators support a range of industry standard time stamp formats, and also offer a choice of resolution to suit different types of applications.
 
64-bit time stamp formats:
  • 2 Windows formats with 10-ns or 100-ns resolution
  • Native UNIX format with 10-ns resolution
  • 2 PCAP formats with 1-ns or 1000-ns resolution
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 close knowledge of server architecture, as well as real life experience from our manufacturing customers. 
 
Napatech accelerators 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 by orders of magnitude. Not only that, but the performance can also be scaled by using faster processors or more processing cores. 
 
Napatech accelerators support different distribution schemes that are fully configurable: 
 
  • Distribution per Port: All frames captured on a physical port are transferred to the same CPU core for processing
  • Distribution per Traffic Type: Frames of the same protocol type are transferred to the same CPU core for processing
  • Distribution by Flows: Frames with the same hash value are sent to the same CPU core for processing
  • Combinations of the Above
