```
Note that with version 3.40 of ns-3, the “neighbor-cache” test fails without any connection or consequence to our library. However, the “mobility-trace,” “attributes,” “data-rate,” and “time” tests fail because of our library. Indeed, in order to simulate communications at over 1Gb/s, the “ethernet-test-suite.cc” test sets the time resolution to picoseconds instead of nanoseconds, thus causing side effects in other tests. Line 996 (i.e. “Time::SetResolution(Time::PS);”) can be commented out to resolve this issue.
To run an example (e.g. "ethernet-point2point.cc") :

* Two flows go from ESsource to ESdest. Only the VLAN 100 and 101 flow use FRER mechanisms.

/**
* \file
*
* Example with 3ES connected 4SW in a 1Gb/s full duplex link to demonstrate
* the difference between two FRER sub-mechanisms : the match recovery algorithm
* and the vector recovery algorithm. To be more specific this example use the
* SW1 to do the replication using mulitcast and SW4 to do the elimination for
* the flow with VlanId = 100. The stream identification is done by the null
* stream identification function. The match recovery function, latent error
* detection function are also used in this example. The Vlan 100 flow go from
* ESsource to ESdest and Vlan 101 flow go from ESPerturbation1 to ESdest.
*
* ESPerturbation1
* ||
* / ==== SW2 ==== \
* ESsource ==== SW1 SW4 ==== ESdest
* \ ==== SW3 ==== /
*
* When using match recovery algorithm, we can note that some packet are received
* multiple times (pkt #2, #3, #4, #5, ..., #9) because Vlan 100 flow is bursty
* and disrupt by the Vlan 101 flow. This behavior is not observed with vector
* recovery algorithm because it store multiple FRER sequence number to do
* the elimination.
*
*
* This example script can be run using one of this two following commands
* according to the algorithm needed :
* ./ns3 run <path to the script> -- --match
* ./ns3 run <path to the script> -- --vector

/**

*
* Example with 2ES connected 2SW in a 1Gb/s full duplex link to demonstrate
* FRER usage when replication and elimation are done on the ES. To be more
* specific this example use the ESsource to do the replication using mulitcast
* and ESdest to do the elimination. The stream identification is
* done by the null stream identification function. The match recovery function,
* latent error detection function are also used in this example.
* Two flows go from ESsource to ESdest. Only the VLAN 100 flow use FRER mechanisms.
*
* / ==== SW1 ==== \
* ESsource ESdest
* \ ==== SW2 ==== /
*
* Although mutliple ways of implementing elimination and replication on ES are
* describe in the standard (IEEE802.1CB-2017 - Annex C), here we implement the
* one describe in "IEEE802.1CB-2017 - Annex C - C.6 Example 6: Chained two-port
* end systems". This ways is based on the use of a 3-port switch integrated
* into the ES to interface between the ES and the network as described below
*
