Network function virtualization (NFV) introduces great flexibility in designing software-based network appliances to reduce cost and accelerate service deployment for network operators. However, with the fast development of high speed network of 100 GbE and beyond, how to efficiently design virtual network functions (VNF) on commodity servers has become a challenging problem. Although the advances...
The programmability of the network data plane has become one of the most desirable features within the context of software defined networks, with P4 serving as a domain-specific language for defining data plane processing. In this work, we are motivated to address the challenges of mapping a P4 defined data plane to a heterogeneous programmable hardware architecture consisting of both a CPU and a...
Emerging new network applications challenge the existing Internet infrastructure and call for flexible and open network facilities that can provide virtual networks for conducting experiments or deploying new services. In this paper, we propose to use hybrid multi-core processors including general purpose ones and network processors as the main processing elements of a programmable edge node (PEN),...
