Greetings OVS Team, We have been working on adding OVS support for the IEEE/IETF Auto-Attach SPBm draft standard. This standard describes a compact method of using IEEE 802.1AB Link Layer Discovery Protocol (LLDP) together with a IEEE 802.1aq Shortest Path Bridging (SPBm) network to automatically attach network devices to individual services in a SPBm network. The intent here is to allow network applications and devices using OVS to be able to easily take advantage of features offered by industry standard SPBm networks. Details of the Auto-Attach standard can be found here.
http://tools.ietf.org/html/draft-unbehagen-lldp-spb-00 In addition to this standards work we have proposed Auto-Attach to the IEEE 802.1Q technical committee for inclusion into that standard. This IEEE standards work is ongoing and the initial reaction from the standards committee has been very positive. Specifically we have modified the OVS source code to integrate basic LLDP protocol support as required to implement the Auto-Attach (AA) standard. We modeled our LLDP code changes after other protocols currently supported by OVS (BFD, CFM, etc.). We have chosen to base this OVS LLDP work on the open source LLDPD project headed by Vincent Bernat. Details of the LLDPD project can be found here. http://vincentbernat.github.io/lldpd Although the LLDPD project provides a full LLDP implementation as per the IEEE 802.1AB standard, our initial offering focuses on the core pieces of LLDP required to provide AA support. We have plans in place to extend this work to include full LLDP support within OVS. We have reached a point in our development where we would like to engage the OVS development community regarding how best to contribute our work upstream. We have integrated core LLDP support into OVS and have augmented that to support Auto-Attach. We have extended OVSDB and unixctl adding new commands to support the configuration, status display, and statistics display of Auto-Attach. We have added the associated man pages for these new commands. We have extensively tested the Auto-Attach feature within both the standalone WindRiver Linux and the VmWare vSphere environments. We recently demonstrated this technology at VMworld 2014. We have also confirmed that all OVS unit tests pass with our code changes in place. While there is more Auto-Attach work to be done we feel we are at a point where it makes sense to start presenting this new Auto-Attach feature upstream for your consideration. This is our first engagement with the OVS team. We have familiarized ourselves with the upstream procedures as defined within the file .../CONTRIBUTING and are working to ensure conformance to OVS coding standards. We have viewed various videos and tutorials describing the OVS development processes and best practices. We are not sanctioned OVS source code committers. We welcome any additional suggestions/guidance you might have before we proceed.
