S6: Elastic Scaling of Stateful Network Functions

Contains

• S6 runtime library (/core) and souce-to-source compiler (/gen_source)
• A sample NF controller (/s6ctl)
• Sample applications (/sample)

Running environment

• We have tested S6 in Ubuntu Server 16.04 LTS
• An NF instance can run as a process or a container
• We used Amazon EC2 for elastic scaling experiments (c4.xlarge)

Compiling S6 library

Prerequisites: basic utilities

• gcc, g++, make
• python 2.7
• python-clang-3.6 (s2s compiler)
• libclang-3.6-dev (s2s compiler)
• linux-headers (DPDK)
• unzip (Rapidjson)
• libssl-dev (sample applications)
• libpcre3-dev (DPI)
• libpcap-dev (PRAD)

Prerequisites: 3rd-party libraries

• C++ BOOST
• Rapidjson
• DPDK
• BESS (for the sample NF controller)
