From f1b7de05ac886a58a994676a4a5b6591eed5fc91 Mon Sep 17 00:00:00 2001 From: Luc Provoost Date: Mon, 12 Feb 2018 11:32:35 +0100 Subject: Zero packet loss testing has been added. Using l2 testing, where no ARP messages are being used, you can now run a zero packet loss test. The binary search will continue to find the speed where absolutely no packets have been lost during the test. On top of that, the output has been reformatted to also show the absolute and relative packet loss. The *.test files have now 2 new parameters: drop_rate_treshold and accuracy. When drop_rate_treshold is set to 0, this test will conclude successfull when no packet has been lost whatsoever. If this is set to any other number, the test will be successfull when the relative packet loss is lower than drop_rate_treshold. The new accuray parameter defines when the binary search will stop: when the relative difference between the min and max of the search window is lower than accuracy. The irq testing is slightly modified to print the total number of interrupts in a certain time bucket, not only as the number per second, but when there is no interrupt whatsowever, we print '0' in stead of '0.0' Change-Id: I8fafded0a225cbe1ba7ac61cd28e94d72099e4a0 Signed-off-by: Luc Provoost --- .../helper-scripts/openstackrapid/3VMrapid.yaml | 6 +- .../openstackrapid/3VMsriovrapid.yaml | 6 +- .../helper-scripts/openstackrapid/basicrapid.test | 2 + .../helper-scripts/openstackrapid/impair.test | 3 + .../helper-scripts/openstackrapid/irq.test | 7 +- .../helper-scripts/openstackrapid/l2gen.cfg | 61 ++++++++ .../helper-scripts/openstackrapid/l2swap.cfg | 44 ++++++ .../helper-scripts/openstackrapid/l2zeroloss.test | 51 +++++++ .../helper-scripts/openstackrapid/rapid.yaml | 6 +- .../helper-scripts/openstackrapid/runrapid.py | 154 ++++++++++++--------- .../helper-scripts/openstackrapid/secgw.test | 3 +- .../helper-scripts/openstackrapid/sriovrapid.yaml | 6 +- 12 files changed, 277 insertions(+), 72 deletions(-) create mode 100644 VNFs/DPPD-PROX/helper-scripts/openstackrapid/l2gen.cfg create mode 100644 VNFs/DPPD-PROX/helper-scripts/openstackrapid/l2swap.cfg create mode 100644 VNFs/DPPD-PROX/helper-scripts/openstackrapid/l2zeroloss.test (limited to 'VNFs/DPPD-PROX') diff --git a/VNFs/DPPD-PROX/helper-scripts/openstackrapid/3VMrapid.yaml b/VNFs/DPPD-PROX/helper-scripts/openstackrapid/3VMrapid.yaml index 99bbd20a..44099d9d 100644 --- a/VNFs/DPPD-PROX/helper-scripts/openstackrapid/3VMrapid.yaml +++ b/VNFs/DPPD-PROX/helper-scripts/openstackrapid/3VMrapid.yaml @@ -51,6 +51,10 @@ parameters: type: string description: The Availability Zone to launch the instance. default: nova + vm1_availability_zone: + type: string + description: The Availability Zone to launch the instance. + default: nova resources: vm1_admin_port: @@ -73,7 +77,7 @@ resources: vm1: type: OS::Nova::Server properties: - availability_zone: { get_param: availability_zone } + availability_zone: { get_param: vm1_availability_zone } user_data: get_file: prox_user_data.sh key_name: { get_param: key } diff --git a/VNFs/DPPD-PROX/helper-scripts/openstackrapid/3VMsriovrapid.yaml b/VNFs/DPPD-PROX/helper-scripts/openstackrapid/3VMsriovrapid.yaml index 07a039ff..0ad39b8a 100644 --- a/VNFs/DPPD-PROX/helper-scripts/openstackrapid/3VMsriovrapid.yaml +++ b/VNFs/DPPD-PROX/helper-scripts/openstackrapid/3VMsriovrapid.yaml @@ -51,6 +51,10 @@ parameters: type: string description: The Availability Zone to launch the instance. default: nova + vm1_availability_zone: + type: string + description: The Availability Zone to launch the instance. + default: nova vm1_sriov_port: type: string description: The sriov port to be used by VM1 @@ -79,7 +83,7 @@ resources: vm1: type: OS::Nova::Server properties: - availability_zone: { get_param: availability_zone } + availability_zone: { get_param: vm1_availability_zone } user_data: get_file: prox_user_data.sh key_name: { get_param: key } diff --git a/VNFs/DPPD-PROX/helper-scripts/openstackrapid/basicrapid.test b/VNFs/DPPD-PROX/helper-scripts/openstackrapid/basicrapid.test index fde148f6..4a94c35f 100644 --- a/VNFs/DPPD-PROX/helper-scripts/openstackrapid/basicrapid.test +++ b/VNFs/DPPD-PROX/helper-scripts/openstackrapid/basicrapid.test @@ -25,6 +25,8 @@ script_control = false group1cores = not_used group2cores = not_used group3cores = not_used +drop_rate_treshold = 1 +accuracy = 0.01 [VM1] diff --git a/VNFs/DPPD-PROX/helper-scripts/openstackrapid/impair.test b/VNFs/DPPD-PROX/helper-scripts/openstackrapid/impair.test index 9c9fba26..71ae3e12 100644 --- a/VNFs/DPPD-PROX/helper-scripts/openstackrapid/impair.test +++ b/VNFs/DPPD-PROX/helper-scripts/openstackrapid/impair.test @@ -25,6 +25,9 @@ script_control = false group1cores = not_used group2cores = not_used group3cores = not_used +drop_rate_treshold = 1 +accuracy = 0.01 + [VM1] name = Generator diff --git a/VNFs/DPPD-PROX/helper-scripts/openstackrapid/irq.test b/VNFs/DPPD-PROX/helper-scripts/openstackrapid/irq.test index c53a31b9..a732dc8e 100644 --- a/VNFs/DPPD-PROX/helper-scripts/openstackrapid/irq.test +++ b/VNFs/DPPD-PROX/helper-scripts/openstackrapid/irq.test @@ -16,8 +16,8 @@ [DEFAULT] name = BasicSwapTesting -number_of_tests = 1 -total_number_of_vms = 1 +number_of_tests = 2 +total_number_of_vms = 2 init_code= not_used dest_vm = not_used gw_vm = not_used @@ -25,7 +25,8 @@ script_control = false group1cores = not_used group2cores = not_used group3cores = not_used - +drop_rate_treshold = 1 +accuracy = 0.01 [VM1] name = InterruptTesting diff --git a/VNFs/DPPD-PROX/helper-scripts/openstackrapid/l2gen.cfg b/VNFs/DPPD-PROX/helper-scripts/openstackrapid/l2gen.cfg new file mode 100644 index 00000000..bf8b6ded --- /dev/null +++ b/VNFs/DPPD-PROX/helper-scripts/openstackrapid/l2gen.cfg @@ -0,0 +1,61 @@ +;;
