Instead, NFF-Go uses pointers from the DPDK = initialization of the device mbuf structures. It permits copying of packet = data between Go's safe and DPDK/C unsafe memory.

Also, auto-scaling is automatically provided by the built-in scheduler u= sing cores as needed, and freeing them after use. NFF-Go provides an altern= ative development environment for creating network functions using a smalle= r number of lines of code compared to DPDK/C without sacrificing performanc= e. These capabilities make it possible to implement run-till-completion pac= ket processing model. The library includes a component called boundary nod= e, which allows consuming packet data from all types of sources: Ethernet, = file, memory buffer, remote procedure call and then applying the packets to= the processing graph which will be transparently deployed through any clou= d orchestration engine. >>> *Benefit* NFF-Go is based on the DPDK and lowers the entry barrier for = bringing packet processing to less experienced developers and push towards = cloud-native usages.
