This mail is not an official mail of presentation of our work is just I commented you what we are working, I hope not to get ahead imprudently in the presentation of our work, and make false illusions if so my sincere apologies The official mail will be send soon.
First than all my presentation. My name is Luis Zárate, I work for Solvo ( solvosoft.com) and in Solvo we are working in a Universidad de Costa Rica (UCR) project based in VCL. In the UCR we detect that VCL needs a better network approach, because service like DNS, DHCP,NAT, VPN,Firewall are not include as part of reservation (you can set DHCP but not reserve a new dhcp server with specific configurations), so same as machine reservation, we want an network service reservation on demand and scheduled. So we looked how to make this possible and see in SDN approach how to do that. In the past 8 months we studied VCL code and have some observations (this for other mail), We made some diagrams and worked in the new design of VCL network we also started and SDN lab for test. In our SDN Lab we made a overlay network based on GRE tunnels (we have hardware limitations), OpenvSwitch and Ryu with good results, we also being worked in how to automate the service creation and saw it that is possible to incorporated VCL (some code in https://github.com/luisza/sdn_control/, is in python, but I think can be translated to Perl when I feel good with the language). Although our lab is with overlay network I see possible to use other SDN model and controller without several code changes. I also started studying Perl and dojo, I know php and javascript, C/C++ and Python but not Perl and dojo so is part of what I am doing. Attached are an visual idea of how I see the new VCL network system, we are working on mockups right know. We also do an VCL apps approach in django only for understand the database, but it's good to see who we sort the models.
