2009, July 21 - New Centos 5 packages based on the new LiSA kernel module versioning system. The download page has been updated.
2009, July 15 - New versioning system on kernel module, to ensure strict compatibility between kernel and userspace packages. The download page has been updated accordingly and the Fedora 8 packages have been rebuilt.
2009, July 4 - All major functionality is ported to the new CLI (and kernel module) version, including Xen integration. The package building system has been improved and we have pre-built Centos 5 packages.
2009, February 21 - Completely gave up older CLI, since it is no longer compatible with kernel-side code. Our goal now is to port all commands that worked on the old CLI.
2009, February 9 - The new CLI framework is complete. Major layer 2 functionality has been ported from older CLI.
2008, October 29 - We have started to redesign the CLI. The main goals are: more flexibility, better organization of command trees and a simpler API
2008, July 12 - Radu Rendec of the LiSA team is proud to announce the first LiSA gigabit deployment. The "layer 3 switch" is a Duron / 1000 MHz / 512 MB ram machine with four rtl8169 pci nics. It serves as home network core switch/router and is (physically) linked to two Zyxel ES-2008 switches and two gigabit-enabled workstations. Effective throughput between the two gigabit-enabled workstations (measured with FTP traffic) is about 43 MB / s (approx 360 mbit / s).
2008, July 9 - The LiSA kernel module was successfully ported to 2.6.25. The port from 2.6.21 to 2.6.25 was not trivial, because of major network api changes and namespaces implementation in the mainstream kernel.
2008, February 24 - The git repositories can now be browsed online, using cgit (a fast git web interface). To access the repositories, go here.
2008, February 19 - LiSA and Xen integration RPM packages for Fedora 8 are now available for download. Fedora 8 users can get a fully functional LiSA or Xen+LiSA setup by just installing a few RPM packages. The download page is reorganized to include a brief description of all files and versions.
2008, February 18 - Significant site update - the last couple of weeks' work is now published, including a page about the git repositories, and an overview of major LiSA components in the subprojects page.
2008, February 11 - A new release. Includes a merge of the latest development branch. Beside port to linux 2.6.21, it features Xen integration, a complete redesign of userspace components IPC, and a new framework for passing packets from kernel to userspace and vice-versa (cdp daemon also ported).
2007, December 18 - A Bugzilla bug tracking system for LiSA is available here.
2007, December 4 - Xen integration is complete. We need more testing and proper packaging for easy deployment on servers. For further details, please refer to the Xen integration subproject page.
2007, October 14 - Radu Rendec of the LiSA team has started working on a shared memory allocator. Although it's rather generally usable than LiSA specific, its declared purpose is to implement dynamic data structures sharing across isolated processes. For further details, please refer to the MM subproject page.
2007, September 30 - We decided to migrate the version control system to git. All public areas of the old svn repository have been imported into git. Therefore, the old svn repository is no longer available. For further details, please refer to the git repositories page.
2007, September - Inspired by a LiSA user's excellent idea, we have started looking at integrating LiSA with Xen. Because of LiSA's kernel module architecture, switching is expected to work right away. However, virtual domU interfaces in dom0 are renamed at each domU restart, so care must be taken to ensure propper configuration persistance. For further details, please refer to the Xen integration subproject page.
2007, January 5 - A new release. It includes a port to the 2.6.19 kernel.
2006, August 7 - A new release. It includes a port to the 2.6.17 kernel, some bug fixes in the kernel and userspace code, and Cisco Discovery Protocol support.
2006, August 4 - Two mailing lists are now available: LiSA-Users and LiSA-Developers. The LiSA-Users list is intended for general discussion about LiSA features, usage and configuration. The LiSA-Devel list is intended for discussion between developers regarding LiSA structure, various protocol implementation, algorithms, etc.
2006, June 21 - Public read-only access to our project repository is now available.
2006, June 2 - Our project coordinator, Octavian Purdila, presents LiSA at RoEduNet International Conference 2006. The slides are available in OpenOffice format. The paper is available in pdf format.
2006, March 24 - Our own in-depth article on LiSA was published in the online HTML articles section of o3 magazine. The article follows up on John Buswell's article that introduced the project. The same day Greg Jordan of o3 magazine announced the article on News Forge.
2006, March 2 - We'd like to introduce two new team members: Adina Iliescu and Marius Chiriac. As a bachelor degree project, they chose to extend LiSA's functionality. Welcome to the team!
2005, November 29 - Very enthusiastic after reading John Buswell's article, we quickly ported the code to Linux 2.6.14 and made a new release.
2005, November - John Buswell writes about LiSA in the first "issue" of o3 magazine. Although he initially planned to focus his article on LiSA only, the lack of documentation and project activity during the past months discouraged him. However, he managed to compile and test our project with no help from our side. We'd like to thank him for all his effort and for letting more people know about LiSA. See the first "issue" of o3 magazine for further details.
2005, June 15 - A lot of work has been done and now the basic functionality is complete. We've gone through a bug fixing and testing period and now LiSA seems to be pretty stable. The first release is out there to be downloaded. We are very busy with the bachelor degree papers and presentations.
2005, March 23 - We've got working vlan and forwarding databases, and a few ioctl's.
2005, March 12 - We made the first changes in the kernel code and wrote the first lines of code that actually do something (besides the dummy "Hello world" :P).
2005, February 27 - Looks like this is LiSA's birth date :) We made the first entry in the version control system. We only have a few documentation and link files.
