2019-01-29NSB sync: clean-up draft IPC implementation (part 1)Mytnyk, Volodymyr1-4/+5
The existing implementation of IPC is not finished and isn't used by any of the VNFs/TG implementation. It is used in the code but does nothing from functionality perspective. New syncronization mechanism is going to be implemented by using different approach than it was designed before. Thus, the current IPC mechanism is not going to be re-used. So, removing it. The IPC consumer/producer implementation is left as it may be required for other purposes. - Remove SampleVNF MQ consumer class - Remove IterationIPC MQ producer for VNF control messages - Remove MQ producer from SampleVNFTrafficGen class - Remove TrafficGeneratorProducer class - Remove IterationIPC runner - Remove unused task_id form VNF Generic initialization as it is not required for synchronization of VNFs/TGs anymore. - Fix UT JIRA: YARDSTICK-1592 Change-Id: I65fe51bcbd1bfeea0c43eb79ca6fb2aab5b65ae7 Signed-off-by: Mytnyk, Volodymyr <volodymyrx.mytnyk@intel.com>

Improve TRex RFC2544 throughput calculation by using the in/out packets instead of using the throughput samples. JIRA: YARDSTICK-1387 Change-Id: I877e901c3226d31c6435a877a2924bb95deb1cf0 Signed-off-by: Rodolfo Alonso Hernandez <rodolfo.alonso.hernandez@intel.com>
2018-07-13Create a SampleVNF MQ consumer classRodolfo Alonso Hernandez1-5/+4
This new class is designed to be used in a ``GenericVNF`` object (VNF or traffic generator) in a builder pattern. This consumer class will be instantiated when initializing the ``GenericVNF`` derived object. The ``GenericVNFConsumer`` endpoint is the ``GenericVNF``derived object itself. ``GenericVNFEndpoint`` is an interface class to be inherited in a ``GenericVNF`` child object; the VNF object will implement the endpoints methods.

2018-06-18Refactor RFC2455 TRex traffic profile injectionRodolfo Alonso Hernandez1-1/+25
The TRex RFC2455 traffic profile configures the duration of the traffic injection. Once the traffic is started, the traffic profile should poll the traffic injector client for the injection status. When the injection is finished, the traffic execution should end. Instead of this, the traffic profile waits a fixed time (using time.sleep method) and then stops the traffic. This approach is not accurate and may cause shorter injection periods.

2018-01-03Make GenericVNF an abstract classRodolfo Alonso Hernandez1-3/+5
GenericVNF class is now an abstract class. Only optional methods are implemented. Mandatory methods: - instantiate - wait_for_instantiate - terminate - scale - collect_kpi.

2017-11-17Make GenericTrafficGen class abstractRodolfo Alonso Hernandez1-5/+3
GenericTrafficGen class is now an abstract class. Only optional methods are implemented. - 'run_traffic' and 'terminate' are mandatory. - 'listen_traffic', 'verify_traffic' and 'wait_for_instance' are optional. By default these methods doesn't execute any action.

2017-11-14NSB TRex: convert DPDK port number to logical TRex port numberRoss Brattain1-5/+27
when we create TRex config we sort based on PCI bus address and create a logical port ordering. We need to save this port ordering and re-use it everywhere. redirect vnfd_helper.port_num() to resource_helper.port_num() to use the logical mapping Change-Id: Ibff628556d5e11e686e15716a66a3210758c4ff0 Signed-off-by: Ross Brattain <ross.b.brattain@intel.com>
2017-10-18NSB: fix trex config to use dpdk port numberRoss Brattain1-11/+14
From some reason Heat/Neutron is now creating interfaces such that xe0 and xe1 are swapped. xe0 fa:16:3e:38:c7:66 0000:00:05.0 xe1 fa:16:3e:2f:f3:e2 0000:00:03.0 this causes the DPDK port numbering to be swapped. xe0 is DPDK port 1 because it has higher PCI address xe1 is DPDK port 0 because it has lower PCI address. The VNF is configured correctly because it uses DPDK port numbers, whereas TRex was using interface list ordering. Modify trex_cfg.yaml to use DPDK port ordering. This also requires running generate_cfg() after setup() in instantiate() +------------------------------------+-------------------+------------------------------+--------+ | Name | MAC Address | Fixed IP Addresses | Status | +------------------------------------+-------------------+------------------------------+--------+ | vnf_0.yardstick-af5ccb47-xe0-port | fa:16:3e:66:a5:e4 | ip_address='10.1.0.7', | ACTIVE | | vnf_0.yardstick-af5ccb47-mgmt-port | fa:16:3e:fa:98:fe | ip_address='10.0.1.10', | ACTIVE | | tg_0.yardstick-af5ccb47-xe1-port | fa:16:3e:2f:f3:e2 | ip_address='10.1.1.9', | ACTIVE | | vnf_0.yardstick-af5ccb47-xe1-port | fa:16:3e:f3:1d:f5 | ip_address='10.1.1.4', | ACTIVE | | | fa:16:3e:e3:8c:65 | ip_address='10.0.1.1', | ACTIVE | | | fa:16:3e:ff:d1:b7 | ip_address='11.191.14.110', | N/A | | tg_0.yardstick-af5ccb47-xe0-port | fa:16:3e:38:c7:66 | ip_address='10.1.0.8', | ACTIVE | | | fa:16:3e:ff:53:5f | ip_address='11.191.14.101', | DOWN | | | fa:16:3e:23:5d:2c | ip_address='10.0.1.2', | ACTIVE | | tg_0.yardstick-af5ccb47-mgmt-port | fa:16:3e:7a:df:4e | ip_address='10.0.1.5', | ACTIVE | | | fa:16:3e:22:65:36 | ip_address='11.191.14.109', | N/A | +------------------------------------+-------------------+------------------------------+--------+ /sys/devices/pci0000:00/0000:00:03.0/virtio0/net/ens3/address:fa:16:3e:2f:f3:e2 /sys/devices/pci0000:00/0000:00:05.0/virtio2/net/ens5/address:fa:16:3e:38:c7:66 Change-Id: Iaef2c7d9a5af7f45bd805a8ad6ee545ce0495cb1 Signed-off-by: Ross Brattain <ross.b.brattain@intel.com>

set TRex -c option for threads per port based on hardware number of queues. We can't auto-detect number of queues and we can't use more than one thread per core on systems with single-queue interfaces, so move the option to the config file options: tg_0: queues_per_port: 2 also enable trex debug by removing >/dev/null redirection options: tg_0: trex_server_debug: true Change-Id: I46da187849282bf28f4ef5b333e1ae890e202768 Signed-off-by: Deepak S <deepak.s@linux.intel.com> Signed-off-by: Ross Brattain <ross.b.brattain@intel.com>
2017-09-05Add fixes for heat deployed UDP_Replay and TRexMartin Banszel1-4/+15
- Added a PROTOCOL_MAP to map the protocol names to codes -- the scapy requires the code, it fails if the proto is set e.g. to 'udp' - ip addresses must be str, not unicode -- explicit conversion to str added - removed unittest for setup_vnf_environment in test_tg_trex.py as it is the same function as already tested in test_sample_vnf.py - traffic_profile refactored -- code repetition decreased, unittest adapted Known issues: - there is a an attempt to stop already stopped trex. It fires an exception that stop command is issued on the disconnected client. Change-Id: I87e9029630f48b30e8f5b4f9d88ab3b25fd65f03 Signed-off-by: Martin Banszel <martinx.banszel@intel.com>

Refactored main NSB VNF classes accroding to class diagram https://wiki.opnfv.org/display/yardstick/NSB+class+diagram All the SampleVNFs have been separated and placed under the SampleVNF class. Added AutoConnectSSH to automatically create SSH conneciton on demand. Added VnfdHelper class to wrap the VNFD dictionary in prepartion for class-based modeling. Extracted DpdkVnfSetupEnvHelper for DPDK based VNF setup. Extracted Stats and other client config to ResourceHelper Had to replace dict_key_flatten with deepgetitem due to Python 2.7 Jinja2 infinite recursion.

2017-04-11standardize ssh authRoss Brattain1-10/+5
we need to be following defautl paramiko rules, first use pkey, then key_filenames (autodetecting ~/.ssh/ keys), then password We have too much boilerplate redudant code everywhere, we need to standardize on a factory function that takes a node dict. Using Python3 ChainMap we can layer overrides and defaults. VNF descriptors have to default key_filename, password to Python None. The only way to do this is to omit key values if the variable is not defined, this way the dict will not have the value and it will default to Python None Add python2 chainmap backport Updated unittest mocking to use ssh.SSH.from_node Change-Id: I80b0cb606e593b33e317c9e5e8ed0b74da591514 Signed-off-by: Ross Brattain <ross.b.brattain@intel.com>
