Release 3.3.0¶
Major release highlights:
VxLAN support
test VM can now have idle interfaces
test VM can be launched with multiqueue enabled
upgrade to TRex v2.56
Release 2.0¶
NFVbench will now follow its own project release numbering (x.y.z) which is independent of the OPNFV release numbering (opnfv-x.y.z)
Major release highlights:
Dedicated edge networks for each chain
Enhanced chain analysis
Code refactoring and enhanced unit testing
Miscellaneous enhancement
Dedicated edge networks for each chain¶
NFVbench 1.x only supported shared edge networks for all chains. For example, 20xPVP would create only 2 edge networks (left and right) shared by all chains. With NFVbench 2.0, chain networks are dedicated (unshared) by default with an option in the nfvbench configuration to share them. A 20xPVP run will create 2x20 networks instead.
Enhanced chain analysis¶
The new chain analysis improves at multiple levels:
there is now one table for each direction (forward and reverse) that both read from left to right
per-chain packet counters and latency
all-chain aggregate packet counters and latency
supports both shared and dedicated chain networks
Code refactoring and enhanced unit testing¶
The overall code structure is now better partitioned in the following functions:
staging and resource discovery
traffic generator
stats collection
The staging algorithm was rewritten to be:
a lot more robust to errors and to handle better resource reuse use cases. For example when a network with a matching name is discovered the new code will verify that the network is associated to the right VM instance
a lot more strict when it comes to the inventory of MAC addresses. For example the association from each VM MAC to a chain index for each Trex port is handled in a much more strict manner.
Although not all code is unit tested, the most critical parts are unit tested with the use of the mock library. The resulting unit test code can run in isolation without needing a real system under test.
OPNFV Fraser Release¶
Over 30 Jira tickets have been addressed in this release (Jira NFVBENCH-55 to NFVBENCH-78)
The Fraser release adds the following new features:
support for benchmarking non-OpenStack environments (with external setup and no OpenStack openrc file)
PVVP packet path with SRIOV at the edge and vswitch between VMs
support logging events and results through fluentd
Enhancements and main bug fixes:
end to end connectivity for larger chain count is now much more accurate for large chain count - avoiding excessive drops
use newer version of TRex (2.32)
use newer version of testpmd DPDK
NDR/PDR uses actual TX rate to calculate drops - resulting in more accurate results
add pylint to unit testing
add self sufficient and standalone unit testing (without actual testbed)
OPNFV Euphrates Release¶
This is the introductory release for NFVbench. In this release, NFVbench provides the following features/capabilities:
standalone installation with a single Docker container integrating the open source TRex traffic generator
can measure data plane performance for any NFVi full stack
- can setup automatically service chains with the following packet paths:
PVP (physical-VM-physical)
PVVP (physical-VM-VM-physical) intra-node and inter-node
- can setup multiple service chains
N * PVP
N * PVVP
supports any external service chain (pre-set externally) that can do basic IPv4 routing
- can measure
drop rate and latency for any given fixed rate
NDR (No Drop Rate) and PDR (Partial Drop Rate) with configurable drop rates
- traffic specification
any fixed frame size or IMIX
uni or bidirectional traffic
any number of flows
vlan tagging can be enabled or disabled
- user interface:
CLI
REST+socketIO
fully configurable runs with yaml-JSON configuration
detailed results in JSON format
summary tabular results
can send logs and results to one or more fluentd aggregators (per configuration)
