Accolade has introduced the third-generation dual-port 100G network ANIC-200Ku PCIe lossless packet acquisition adapter based on Xilinx UltraScale FPGA, which can analyze each packet in real time from 32 million network data streams. Power consumption is only about 50W, and each network packet can be time stamped with an accuracy of 4 nanoseconds. ANIC-200Ku integrates two CFP4 network cable adapter interfaces (Optical Cage), we can directly connect two ANIC-200Ku to achieve a 200Gbps lossless high-aggregation data stream network.
Figure 1: Accolade's third-generation dual-port 100GE network adapter ANIC-200Ku
NIC-200Ku is suitable for many fields, such as:
Passive and inline network monitoring
Network security and forensics
Inline network deep packet inspection
Network testing and measurement
Network video stream monitoring
High Frequency Trading (HFT, High Frequency Trading)
Application performance monitoring
High Performance Computing (HPC, High Performance Computing)
The ANIC-200Ku implements an advanced Packet Processor system in the integrated Xilinx UltraScale FPGA for real-time processing of network packet flows. The third-generation ANIC-200Ku has added a packet-flow-shunting module on the basis of the previous one. Through different configurations, we can classify different network packets, so as to avoid processing and storing useless network packets. This feature reduces server-side processing pressure and storage requirements, effectively reducing data center design and maintenance costs.
Figure 2: ANIC-200Ku network adapter implementation structure (note the red part)
The advanced packet processor implemented in the ANIC-200Ku board performs a series of packet processing functions (including the red part of the above figure). Each data stream entry contains standard packet header information (source IP address/destination IP address, protocol, etc.), raw data (including total packet count, number of bytes, and previous packet information). The packet classification module can check whether each network packet judges whether it is from a new data stream or an already stored data stream, thereby updating a corresponding storage lookup table (LUT, Look Up Table), and the tracking information also includes the data flow direction to maintain the two-way. Communication content, this feature is equivalent to a network level, effectively reducing the amount of data that needs to be analyzed or processed, thereby freeing up the server CPU resources to perform more urgent tasks.
