Field Descriptions
Packet Size Size of packet generated by Smartbits traffic simulator.
Router Input BPS Bits per second received by test interface (excludes layer 1/2 overhead)
Router Output BPS Bits per second transmitted by test interface (excludes layer 1/2 overhead)
Router Input PPS IP Packets per second received by test interface
Router Input PPS IP Packets per second transmitted by test interface
Input PPP Ohead Encapsulation overhead received for PPP line protocol (6 bytes per packet)
Output PPP Ohead Encapsulation overhead transmitted for PPP line protocol (6 bytes per packet)
Input HDLC Ohead Framing overhead received for sequencing line protocol (1 byte per packet)
Output HDLC Ohead Framing overhead transmitted for sequencing line protocol (1 byte per packet)
Input DS3 Ohead Input overhead for DS3 line framing
Output DS3 Ohead Output overhead for DS3 line framing
Input BPS Total Aggregate BPS of IP packet + PPP overhead + HDLC overhead + DS3 overhead
Output BPS Total Aggregate BPS of IP packet + PPP overhead + HDLC overhead + DS3 overhead
Input percent Line Rate "Input BPS Total" / clock rate of wire (44736000) = Input percent Line Rate
Output percent Line Rate "Output BPS Total" / clock rate of wire (44736000) = Output percent Line Rate
