8 daysFixing eal parameter issue when more than 64 bytesHEADmasterLuc Provoost1-2/+2
Using prox_strncpy to copy eal parameters, so PROX will abort in case the parameter exceeds the maximum string length. Also increased the string length from 64 to 256 bytes. Change-Id: Id7cee03f6b625e165342129e9c2c71216d1144e6 Signed-off-by: Luc Provoost <>

2021-05-12Fix latency buckets with multiple lat coresLuc Provoost3-66/+98
The bucket data of the last latency core was taken into account when collecting the latency stats. We are now adding the bucket data for all cores. Also changed the error reporting when PROX instance is breaking the pipe connection (e.g. when the dataplane network is overloaded).

2021-05-10Reinstate installation of igb_uioLuc Provoost2-1/+9
For good performance on some platforms, we need the igb_uio driver. With this change, the driver is compiled and insmod done during boot time. When running the rapid scripts, the script is sent to the instances (after replacing the string "MACADDRESS"). Make sure you uncomment the proper line to chose which driver you want to use.

2021-05-05New test case: gen versus swap via gatewayLuc Provoost4-10/+134
A new test was added: tests/basicrapid_gw.test. Traffic generated will now go to the reflector (swap instance) via the Gateway. The swap instance will also send the traffic back via the gateway. This use case is created to support GCP testing where the interfaces are defined with a /32 netmask, and hence all traffic is routed via the gateway.

2021-04-30Do not run by defaultLuc Provoost1-10/+12
In the definition of the stack in openstack-rapid.yaml, we define a CloudConfig resource. is called automatically by a service (check-prox-system-setup.service), after each boot. In this file, defined in the CloudConfig resource, you can put instructions needed for succesful operation and to fix certain issues in your environment. By default, this file should NOT be executed, hence we should not have this in the CloudConfig. Change the name back to if you need to execute this code.

2021-04-28Default use of rapid_rsa_keyLuc Provoost6-23/+35
A secret and public key pair is available in the rapid directory: rapid_rsa_key and is now modified to upload this key into OpenStack if the keypair does not already exist in OpenStack. Which keypair to use is now only defined in params_rapid.yaml. You can still define a key pair with a different name in params_rapid.yaml. If the secret and public key files are not available, a new keypair will be created and the secret key file will be saved. The name of the secret key file is the name as the OpenStack keypair name. The name of the public file is the same, with the pub extension. Change-Id: Ib8b5e4bf3a3d3138216698dc588a6908248220c0 Signed-off-by: Luc Provoost <>

2021-04-08cgnat test case addedLuc Provoost6-20/+346
A cgnat test can now be executed. This test needs 3 PROX instances. The first one, the generator needs to have an interface on the private dataplane network. The second instance, the cgnat needs to have it's first dataplane interface on the private network, while the second data plane needs to be on the public network. The third instance will be playing the role of internet server that the generator is connecting to. It will have one dataplane interface on the public network. This third instance will increase the packet size of the received packets by padding it with zeros and it will send the packets back to the cgnat mutliple times. How many times is defined by a multiplier in the cgnat.cfg file. In that cgnat file, we also define a range of IP addresses that will be used for the dynamic source IP NAT-ing. Make sure that the ports are allowed to accept other IP addresses than their own (e.g. allowed address pairs) and that the range of IP addresses is not overlapping with other machines in the public network.

2021-04-07Log ssh & scp related issues also on screenLuc Provoost1-10/+3
When scripts are doing an ssh or scp to the PROX instances, errors were sometimes hidden. E.g. when we try to upload a config file to the PROX instance that is already existing but owned by another user, we would not see the error on the screen. Note this will only happen if you build your own image. In case you use the pre-canned PROX images, this should not cause issues.

2021-03-25Do not request IPV6 routing infoLuc Provoost1-5/+5
PROX is not yet dealing with IPV6 routing info (only IPV4). Hence we got a segmentation fault when receiving such information. In a previous commit, we are checking for IPV4 routing info and we do not continue processing of any other routing information. With this fix, we ask the Linux OS NOT to provide IPV6 routing info. The checks when receiving routing information have changed so that we only treat IPV4 and nothing else. Change-Id: I428a036c31014377c8de08da17e51740be0e1de5 Signed-off-by: Luc Provoost <>

Changed PROX and the python scripts so that the "lat all stats" command also returns the mis_ordered, extent and duplicate statistics. In order to make this work properly, we need now to also stop and restart the latency cores, every time we stop and start the generator cores, since the sequence numbers are reinitialised every time we start the generator core.

2021-02-10Expand mirror functionalityLuc Provoost3-24/+67
In order to deal with non-symmetrical load, the mirror function can now change the packet size of each packet it receives. It can also send the incoming packet multiple times on each of the tx ports. To support this feature, 2 new parameters in the cfg file have been added for the mirror mode: - multiplier: specifies how many times a packet needs to be sent on each tx port. Default is 1. - mirror_size: the size of the packets that need to be sent. This will just change (increase) the packet size of each incoming packet. If not specified or invalid value (e.g. <64), the size will not be changed. The packet size will only be changed for IPv4 UDP and IPv4 TCP. Note that these parameters have no effect on the mirror copy submode. Change-Id: Ic46b52abdd80ed51cffee667bd04ade9ec23ff6d Signed-off-by: Luc Provoost <>

2021-01-27creation of tests and configs subdirectoriesLuc Provoost40-58/+136
All test files are now in the tests directory. All PROX config files moved to the configs directory. When specifying a test on the command line, you should now also mention the directory: e.g. --test tests/basicrapid.test In these test files, you need now to also include the configs subdirectory when specifying the prox configuration that needs to be used. The --map parameter has also changed. It can still take the file name of the map file, that specifies which PROX instance to use during a test. On top of that, you can now also specify a list of indices of the machines to be used during a test: e.g. --map [1,3].

Sending now a 'quit' command to PROX, so that the thread running PROX in an ssh session is now cleaned up correctly. Also fixed a problem with the logging when running the code more than once. We only create handlers now, when they do not yet exist. Updated the rapid version. Also added some more tests in the testcases.yaml for xtesting. At the end of a run, the PROX.log files are copied in the results directory. The success criterium for a test 'pass_threshold' has been removed from the test files and is to be controlled by the xtesting testcases.yaml file.

2020-11-13Fix for latency reporting and log file handlerLuc Provoost3-5/+5
The latency histogram dat did not contain samples collected during the first measurement of each step. The maximum latency did take the first step into account. As a result, you might see a test run with a maximum latency not showing up in the latency histogram data. This has been fixed by also including the data from the first measurement in the histogram data. In some cases, we also reported the wrong speed from the last unsuccessful step. This is now fixed and we do report the speed from the last successful step. In, a fix was added to execute the rollover on the file handler of the log file in all cases. In some cases, the file handler with index 0 was not the file handler of the log file. Change-Id: I6c2b16c21dd0ee17d1d14e46c4c544e185324256 Signed-off-by: Luc Provoost <>

2020-10-19Support dataplane subnet mask & latency histogramLuc Provoost16-36/+76
There is a new parameter in the config_file: dataplane_subnet_mask. This parameter is added to the dataplane IP addresses and is needed by the Linux stack to deal with some protocols (e.g. ARP). If not present, the default value of 24 will be used. In the end, this will make sure that IP addresses in the rapid.env file will have this mask, e.g. /24 If you use other tools than to create the rapid.env file, make sure to add the mask. This commit also introduces a change when exiting: we only copy the prox.log files from the different prox instances in case we expect a new prox.log file to be created in these instances. When using a valid format.yaml file, the tool will now also send the latency distribution data (histogram) to the URL. The tool is now also checking the value of bucket_size_exp: it needs to be 11 or more. Change-Id: I633cdc64ef687fdb6625be1e7482a5a371f83e93 Signed-off-by: Luc Provoost <>
2020-10-16Report failure when tap port is not mapped to real dpdk port.Xavier Simonart4-6/+20
When using "vdev=" in port section, a tap device and an additional dpdk port are created. In most cases, we still want to use a real DPDK device (i.e. bound to an interface such as virtio or a PF or a VF). PROX will now report by default an error when the used [port] is not a DPDK bound device. An additional parameter "virtual=yes" can be added in the port section in case one want to disable this error checking (e.g. specify additional parameter for the vdev device). This patch also fixes a potential endianess issue when configuring IP addresses. Change-Id: Iffdd9552308be3b77cfe2067630647acac2c01fe Signed-off-by: Xavier Simonart <>
2020-09-29New PROX version, background traffic reportingLuc Provoost18-86/+89 is now installing a recent PROX version. When using background traffic, the tool is also reporting the total traffic that was handled by the NFVi stack, including foreground & background traffic. The use of the prox_socket and prox_launch_exit was also broken in a previous release and is now fixed. When setting prox_socket to false for a PROX instance, we will not create a socket connection to control that PROX instance. Setting this option to false is not meaningful for the generator PROX instances since we would not be able to control the behavior of the PROX generator during the test. You could use the generator against another non-PROX instance and then set prox_socket to false for that non-PROX instance. Default is true. prox_launch_exit is used to start and stop the PROX program inside the instance. Default is true. This is useful in case you want to start PROX manually to be able to inspect the PROX UI, but at the same time, let the rapid scripts control the testing.

2020-09-21Added support for reporting packet (mis)order.Xavier Simonart18-48/+227
The "Latency" screen has been updated with 3 columns: - mis-ordered Count the number of mis-ordered packets. - extent: Gives an indication of how mis-ordered the packets are. Receiving packet "x - 5" after receiving packet "x" will cause an extent of 5. - duplicate: Count number of duplicate packets. Following commands have been added for the impair mode: - proba no drop: replaces the former "probability" command. Percentage of forwarded packets. So 99.5 means 0.5% of packet drop. - proba delay Percentage of delayed packets for the impair mode. - proba duplicate Percentage of duplicate packets. Similar parameters are supported within the config files: - proba no drop - proba delay - proba duplicate Note: it is recommanded to use the signature when measuring packet misorder, as otherwise unexpected packet would cause miscounts.
