1. A method, comprising:
- sending, by a computer, a first plurality of data packets into a network, each of the first plurality of sent data packets having a same indicated destination, a same first time-to-live (TTL) indication, and a different differentiated services code point (DSCP) marking;
sending, by the computer, a second plurality of data packets into the network, each of the second plurality of sent data packets having the same indicated destination, a same second TTL indication different from the first TTL indication, and a different DSCP marking;
for each of the first and second pluralities of sent data packets, the computer receiving a reply data packet that identifies the sent data packet, that identifies the computer as a destination of the reply data packet, and that further identifies a DSCP marking;
for each of the reply data packets, the computer determining the DSCP marking identified by the reply data packet; and
causing a display device to display, for each of the first and second TTL indications, an indication of the determined DSCP markings of the reply data packets that correspond to the sent data packets having that TTL indication.

Abstract
The embodiments described herein include a system and method for monitoring a packet adapted to traverse a network having a plurality of devices. The system and method enable an operator to efficiently determine the marking of a packet at each intermediate hop and the destination within a network by executing an algorithm through the use of an operating system.

4. An apparatus, comprising:
a computer configured to; send a first plurality of data packets into a network, each of the first plurality of sent data packets having a same indicated destination, a same first time-to-live (TTL) indication, and a different differentiated services code point (DSCP) marking; send a second plurality of data packets into the network, each of the second plurality of sent data packets having the same indicated destination, a same second TTL indication different from the first TTL indication, and a different DSCP marking; for each of a plurality of received reply data packets that each identifies one of the first or second pluralities of sent data packets, that each identifies the computer as a destination of the reply data packet, and that each identifies a DSCP marking, determine the DSCP marking identified by the reply data packet; and cause a display device to display, for each of the first and second TTL indications, an indication of the determined DSCP markings of the reply data packets that correspond to the sent data packets having that TTL indication. - View Dependent Claims (5, 6)

7. A method, comprising:
-
sending, by a computer, a first plurality of data packets into a network, each of the first plurality of sent data packets having a same indicated destination, a same first time-to-live (TTL) indication, and a different differentiated services code point (DSCP) marking; sending, by the computer, a second plurality of data packets into the network, each of the second plurality of sent data packets having a same second TTL indication different from the first TTL indication, and a different differentiated services code point (DSCP) marking; for each of the first and second pluralities of sent data packets, the computer receiving a reply message that identifies the sent data packet, that identifies the computer as a destination of the reply message, and that further identifies a differentiated services code point (DSCP) marking; for each of the reply messages, the computer determining the differentiated services code point (DSCP) marking identified by the reply message; and causing a display device to display, for each of the first and second TTL indications, an indication of the determined differentiated services code point (DSCP) markings of the reply messages that correspond to the sent data packets having that TTL indication. - View Dependent Claims (8, 9, 10)
