1, Opendaylight was established earlier than ONOS, and there are more developers than ONOS, so ODL is more mature than ONOS.
ODL is mainly an open source platform composed of various vendors, and supports various protocols including Openflow in the south. In the lithium version released at the end of June, ODL added six southbound protocols. At present, there are many operators using ODL, at & amp； T Domain 2.0 mainly uses ODL's SDN controller, and other operators such as comcast, cablelabs, telephonica and Orange are all using ODL. At present, there are more than 20 companies developing in ODL, and it is expected that the number will reach 40-50 next year.
2. The origin of 2.ONOS lies in. The laboratory led by Stanford University. At the end of last year, some codes were made public, mainly from the use cases of operators, and then some enhancements were made in distribution, clustering and high reliability. Because their current code base is not large, it is easier to do some optimization. In terms of functions, it supports southbound protocols. , not as good as ODL.
In addition, ONOS is not model-driven at present, and its MD-SAL and support for YANG model are not available in ONOS.
3.ONOS is still in its infancy, and there is almost no support in the data center. ODL and ONOS have their own advantages in the field of operators. In fact, at present, the complementarity between the two even exceeds the conflict.
