Detection of load balanced links in internet protocol networks
First Claim
1. A method for detecting load balancing in a distributed processing network, comprising:
- providing a baseline topology;
selecting, from the baseline topology, first and second addresses associated with first and second routers, respectively, wherein the first router has an associated first hop count relative to a selected node and the second router an associated second hop count relative to the selected node and wherein the first hop count is less than the second hop count;
transmitting at least one test packet, the at least one test packet having a time to live equal to or greater than the second hop count;
receiving at least one response associated with the test packets; and
determining, based on the at least one response, whether load balancing is in effect at the first router.

Abstract
A system for detecting load balancing in a distributed processing network is provided that includes:
(a) a memory 204 comprising a baseline topology 216; and
(b) a processor 208 operable to:
(i) select, from the baseline topology 216, first and second addresses associated with first and second routers 224 and 228, respectively, wherein the first router 224 has an associated first hop count relative to a selected node 200 and the second router 228 an associated second hop count relative to the selected node 200 and wherein the first hop count is less than the second hop count;
(ii) transmit at least one test packet, the at least one test packet having a time to live equal to or greater than the second hop count;
(iii) receive at least one response associated with the test packets; and
(iv) determine, based on the at least one response, whether load balancing is in effect at the first router 224.

12. A method for identifying per-packet load balancing, comprising:
-
providing a baseline topology;
selecting, from the baseline topology, first and second addresses associated with first and second routers, respectively, wherein the first router has an associated first hop count relative to a selected node and the second router an associated second hop count relative to the selected node and wherein the first hop count is less than the second hop count;
transmitting a plurality of test packets from a common source address to a common selected destination address, each of the test packets having a time to live equal to or greater than the second hop count;
receiving a plurality of responses associated with the test packets; and
determining, based on the responses, whether per-packet load balancing is in effect at the first router. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method for identifying per-packet load balancing, comprising:
-
providing a baseline topology;
selecting, from the baseline topology, first and second addresses associated with first and second routers, respectively, wherein the first router has an associated first hop count relative to a selected node and the second router an associated second hop count relative to the selected node and wherein the first hop count is less than the second hop count;
transmitting a plurality of test packets from a common source address to a plurality of differing destination addresses, each of the test packets having a time to live equal to or greater than the second hop count;
receiving a plurality of responses associated with the test packets; and
determining, based on the at least one response, whether one of per-destination and per-source/destination packet load balancing is in effect at the first router. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32)
