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.
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
With hardware time stamps, individual frames can be time-stamped with high precision. However, to assure that the time stamps in frames from different accelerators in the same, or even different, appliances are comparable, the clocks driving the time stamp engines must be synchronized. Napatech has advanced HW time synchronization between accelerators.
There are various mechanisms to provide time synchronization, including synchronization with the operating system clock, known as OS time synchronization. However, for the best accuracy, a hardware-based time synchronization solution based on an industry standard time synchronization protocol should be used. For many applications that rely on accurate time stamps to understand when an event occurred or accurately measure delay across high-speed networks, nanosecond accuracy is essential.
Napatech accelerators provide flexible support for a range of standard time synchronization mechanisms. Dedicated time synchronization connectors enable direct time signal input from an external time source and retransmission of time synchronization signals to other accelerators. In this way, multiple accelerators in the same host or in different hosts will operate in lockstep in a large synchronous installation.
Napatech accelerators are designed to accommodate the time synchronization mechanisms available during deployment. With dedicated ports that can accommodate multiple time synchronization protocols, Napatech provides a flexible solution that does not need to sacrifice ports which are normally used for capture and transmission.
The following list contains some of the time synchronization mechanisms supported:
- IEEE 1588-2008 /PTPv2 Time Synchronization
- PPS Time Synchronization
- GPS and CDMA Time Synchronization over PPS and Server Serial Port
- OS Time Synchronization
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.
