Workshop on NEtwork Accelerated FunctIOns

The IEEE International Workshop on NEtwork Accelerated FunctIOns (NEAF-IO '17) will be held on July 3, 2017 in Bologna, Italy along with the 3rd IEEE International Conference on Network Softwarization (NetSoft 2017). It will be the first track of the Workshop on Hot topics in softwarized networks.

Virtual software network functions (VNFs) enable easy scaling and on-demand provisioning. However, meeting the performance requirements of modern networks is hard when using (virtualized) software only. New VNFs could leverage the network itself to scale their designs to the required performance and reliability levels. For instance, load balancers could offload forwarding decisions to SDN devices based on OpenFlow. Novel technologies based on reconfigurable hardware, such as P4-based switches, can implement stateful forwarding algorithms, delegating to the switch functions that could not be programmed on legacy devices. Furthermore, a new generation of smart network interface cards (NICs) promise to introduce programmability also at the NIC level. Given the above considerations, this workshop has the aim of openly discussing novel design methods and future trends that blur the demarcation line between the functions provided by the network and those provided by VNFs.

Submissions guidelines

Authors are invited to submit only original papers (written in English) not published or submitted for publication elsewhere. Papers can be up to 4 pages. Papers should be in IEEE 2-column US-Letter style using IEEE Conference templates and submitted in PDF format via the JEMS submission site. Papers exceeding these limits, multiple submissions, and self-plagiarized papers will be rejected without further review. All submitted papers will be subject to a peer-review process. The accepted papers will be published in the NEAF-IO Workshop 2017 Proceedings and appear in IEEE Xplore®.

Special workshop format
The goal of this workshop is to allow an active discussion on the topic. To achieve this, the authors of accepted papers are expected to present their work in a 20min talk which is then followed by a 25min discussion phase.
