Yardstick Test Case Description TC073

Throughput per NFVI node test
test case id	OPNFV_YARDSTICK_TC073_Network latency and throughput between nodes
metric	Network latency and throughput
test purpose	To evaluate the IaaS network performance with regards to flows and throughput, such as if and how different amounts of packet sizes and flows matter for the throughput between nodes in one pod.
configuration	file: opnfv_yardstick_tc073.yaml Packet size: default 1024 bytes. Test length: default 20 seconds. The client and server are distributed on different nodes. For SLA max_mean_latency is set to 100.
test tool	netperf Netperf is a software application that provides network bandwidth testing between two hosts on a network. It supports Unix domain sockets, TCP, SCTP, DLPI and UDP via BSD Sockets. Netperf provides a number of predefined tests e.g. to measure bulk (unidirectional) data transfer or request response performance. (netperf is not always part of a Linux distribution, hence it needs to be installed.)
references	netperf Man pages ETSI-NFV-TST001
applicability	Test can be configured with different packet sizes and test duration. Default values exist. SLA (optional): max_mean_latency
pre-test conditions	The POD can be reached by external ip and logged on via ssh
test sequence	description and expected result
step 1	Install netperf tool on each specified node, one is as the server, and the other as the client.
step 2	Log on to the client node and use the netperf command to execute the network performance test
step 3	The throughput results stored.
test verdict	Fails only if SLA is not passed, or if there is a test case execution problem.
