Open Compute Carrier-grade Edge Reference Architecture (OCCERA)
Cloud computing calls for a transformation of ICT equipment
With the recent technical advancements of the mobile Internet, data centers and big data processing, cloud computing is becoming the mainstream service delivery model of the future, causing the traditional Information and Communication Technologies (ICT) market to experience a huge transformation. The construction of traditional ICT equipment was usually based on old design methodology which packaged the computing, storage and IO resources into a single physical entity according to the initial maximum demands. This often necessitated a redesign of existing equipment to adapt to the requirements of a new application appliance, sometimes with only a small hardware change. A fundamental requirement of cloud computing is "resources on demand", meaning that computing, storage and IO resources can be combined flexibly to meet an application's requirements. This requires the computing, storage and IO to be decoupled into different functional modules in the early design phase. Then, based on the requirements of a concrete application, these independent functional modules are chosen in the necessary proportions, and then combined into a specific hardware entity. The OCCERA from ADLINK Technology was created to realize this concept.
Enabling the transformation of ICT computing infrastructure and a smooth evolution to OCP
At its core, the OCCERA has assimilated the latest technologies from Internet data centers, particularly the latest advancements in NFV and SDN. At the same time, OCCERA has also integrated the aspects of traditional industrial computing equipment, such as modular architectures, hardware-assisted acceleration and carrier-grade design standards.
In the first column of the following table lists the key requirements of industrial ICT equipment, particularly those for video and network security processing. It is readily apparent that these requirements reflect the latest advancements of Internet data centers, while also having a strong relationship with traditional industrial computing requirements. OCCERA makes it possible to apply the latest NFV and SDN technologies to industrial computing while preserving the key features of traditional industrial computing, allowing video, network security and telecom equipment providers to make the step into the cloud era with ease and efficiency.
