New 5G Data Center Models: CORD, M-CORD, Mobile Edge Computing
With the promise of greater bandwidth and lower latency, 5G networks will require data center services that are closer to both the users and the mobile edge. Two key innovations to watch here are CORD/M-CORD and Mobile Edge Computing (Multi-access Edge Computing).
CORD (Central Office Re-architected as a Datacenter) is a project within the Linux Foundation that has been driven primarily by AT&T and ON.Lab (an open networking organization). It sets out the vision of having a mini data center located at a central office that is able to run key network services – primarily for wireline access. With M-CORD, the team, along with Verizon, has demonstrated a mobile version of CORD.
Similar ideas have emerged from the Mobile Edge Computing (MEC) network architecture concept, the main idea of which is to place computing services at the edge of the network. This will be important for 5G services as it provides computing services close to the users to ensure low-latency and high-bandwidth capabilities. Examples of services at the edge include video caching and media processing for augmented and virtual reality.
What to Expect in 5G in 2017 and 2018
In terms of 5G predictions, much is still unknown because of the still fluid nature of the 5G standardization process, the difficulty in defining use cases, and the sheer complexity of bringing together all the elements that are expected to enable this next generation of mobile networks.
