We heard rumors that the Open Network Operating System (ONOS) and the OpenDaylight Project (ODL) were considering merging. Our sources were correct. However, Huawei — which participates in both groups — says it’s not going to happen.
There is a general desire within the software-defined networking (SDN) and network functions virtualization (NFV) communities to consolidate open source coding work. Many have complained that there are too many open source projects. And from the standpoint of vendors and service providers, it’s a hassle and an expense to dedicate people to multiple groups.
“We’re not claiming any winners or losers,” says Sharma. “ONOS’s core architecture is more suited to service providers, and ODL was from the data center principally and is for enterprises. The architectures are central and distributed. Those are too difficult to converge into one. ONOS is working in the central office and ODL for the smart city.”
ONOS just this year joined with the Linux Foundation. At that time, some suggested ONOS and ODL were too similar to remain separate projects. But Sharma says another reason not to merge is that the two groups have fundamentally different communities. The ONOS community is deep; it’s focused on particular service provider use cases. ODL is more broad with lots of contributions from a lot of partners.
