1. A method comprising:

  • receiving, from a sensor of a plurality of sensors in a network, information of a first packet sent by a component of the network, the plurality of sensors configured to sense information of data packets moving through the network;

    analyzing the information of the first packet to determine an expected acknowledgement (ACK) sequence number associated with the first packet;

    receiving information of a following packet received by the component;

    analyzing the information of the following packet to determine an ACK sequence number of the following packet;

    determining that the ACK sequence number of the following packet matches the expected ACK sequence number;

    determining a round trip time (RTT) of the first packet based upon the information of the first packet and the information of the following packet;

    receiving, from the plurality of sensors, information of transmission control protocol (TCP) hand-shakes of the network within a specific time period; and

    determining a number of re-transmission packets and new packets during the specific time period based upon the information of TCP hand-shakes.
