PMUX There are multiple Packet Multiplexers (PMUXs) in VMX-Capture.
SmartNIC hardware, firmware, and software capture, buffer, filter, and route packets into packet streams. PMUXs then read packets from the streams. Usually there is one PMUX for each packet stream; however multiple PMUXs can share a packet stream for scalability. The packets received at a SmartNIC capture port can contain traffic from a tap, Mirror Port, or Packet Broker, and may contain a blend of packets from multiple applications and servers at multiple points in the network. Typically, VLAN tags are used to provide a means of representing multiple physical parts of a network infrastructure.
A PMUX then feeds probes, which process selected packets, either by capturing to disk, or by decoding and then performing further analysis.
