TK242

• Lossless, protocol-agnostic, simultaneous ingest of two 100 GbE 100GBASE-CR4 sources
• Nanosecond resolution packet head timestamping on both ingress ports
• Online, in-flight fusing of both ports into a single time-monotonic ordered stream
• Runtime programmable 200 Gbps RSS filter, 6-tuple, 64K entry flow-table, queue routing
• Online, in-flight generation in hardware of multiple, parallel PCAP format byte streams
• PCie Gen4x16 sustained throughput over 200 Gbps from Ethernet to user space host memory
• Exceptionally low host CPU utilization - all formatting, including PCAP generation, in hardware

• Two 100 GbE RX ports, 64K RSS flow direction, in-flight PCAP file generation, Gen4x16 PCIe
• A turnkey, off-the-shelf, targeted, board-level bitstream application: No FPGA design required
• Host Example Design showing TK242 capabilities with an open-source, 3-clause BSD license

• QSFP-DD provides two 100 GbE CAUI-4 RX
• Each of the two parallel input channels has:
  • 100 GbE PHY/PCS/MAC with RX head timestamps
  • Atomic Rules MTAU Layer-2 Pre Filter
  • Rich per-port RX statistics
  • TimeServo System Timer
  • Nanosecond resolution time
  • Time Ordered Packet Merge of both streams
  • Single 200 Gbps / 300 Mpps output stream

• Line rate 200 Gbps / 300 Mpps RSS 6-tuple hashing
  • Software programmable polynomial
  • Default Microsoft Toeplitz weights
• 64K Entry Flow Redirection Table
  • Each entry identifies a unique PCAP flow direction
  • or it can identify a flow to be discarded
  • Use cases include:
    • Send everything allowed to a single PCAP flow
    • RSS Spread allowed incoming packets among the multiple PCAP flows
    • Forward only specific matches to host for lawful intercept
• Multiple Parallel H/W PCAP generators (P2PCAP)
  • Nanosecond per-packet headers added
  • Each supports the full 200 Gbps / 300 Mpps flow
• Atomic Rules Arkville® Data Mover (ADM)
  • PCIe Gen4 endpoint supporting over 200 Gbps

There are many ways TK242 may be leveraged for your own
solution. Here are a few of them..

• As-Is, Out-Of-The-Box, Plug-and-Go Packet Capture
  • Add board, host, plug in and capture packets using Atomic Rules
    supplied example design. Limited to what is demonstrated
• Point your host application code at the in-memory hugepages
  filled with PCAP formatted byte streams
  • The example design is your starting point. Add other capabilitiesbefore, during, and after packet capture. Most features are programmed through the DPDK.org standard API
• Modify the example design to provide other functionality
  • For example, each P2PCAP flow could become its own libpcap stream, feeding its own host core
