Features for Developers
|
|
=======================
|
|
|
|
This section describes a little about the VPP environment and some of the features
|
|
that can be used by developers.
|
|
|
|
* Extensive runtime counters; throughput, `intructions per cycle <https://en.wikipedia.org/wiki/Instructions_per_cycle>`_, errors, events etc.
|
|
* Integrated pipeline tracing facilities
|
|
* Multi-language API bindings
|
|
* Integrated command line for debugging
|
|
* Fault-tolerant and upgradable
|
|
|
|
* Runs as a standard user-space process for fault tolerance, software crashes seldom require more than a process restart.
|
|
* Improved fault-tolerance and upgradability when compared to running similar packet processing in the kernel, software updates never require system reboots.
|
|
* Development experience is easier compared to similar kernel code
|
|
* Hardware isolation and protection (`iommu <https://en.wikipedia.org/wiki/Input%E2%80%93output_memory_management_unit>`_)
|
|
|
|
* Built for security
|
|
|
|
* Extensive white-box testing
|
|
* Image segment base address randomization
|
|
* Shared-memory segment base address randomization
|
|
* Stack bounds checking
|
|
* Static analysis with `Coverity <https://en.wikipedia.org/wiki/Coverity>`_
