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, 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)

• 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
