China Telecom is gradually promoting the deployment of OpenStack in cloud data centers. While network is the key link of the entire cloud solution, the current use of commercial overlay sdn products has greatly limited the open compatibility due to vendor lock-in. With the continuous evolution of Software Defined Network (SDN), the enormous challenge of heterogeneous mixing has been placed in front of China Telecom’s cloud operation.
The SDN collaboration platform (SDN HUB) developed by China Telecom together with 99Cloud, Huawei, ZTE and other companies is dedicated for the above problem. It enhances OpenStack Neutron with the ability of operating multiple sdn networks in a single panel, provides interconnectivity & interoperability abilities among multiple vendor sdn solutions. In general, SDN Hub is a network orchestrator for openstack & other cloud service with cross-domain, cross-vendor & cross-sdn controller ability.
