A Novel Fog Computing Based Architecture to Improve the Performance in Content Delivery Networks

Table 1

Comparison of information-centric and host-centric networking.

	Information-centric networking	Host-centric networking
Naming	Content name is persistent and unique.	Host name can easily break and is not aware of the existence of replica content.
Security Model	Secures the content itself, which allows for stronger, more flexible, and customizable content protection.	Secures the host-to-host communication channels.
Mobility of Nodes	Does not affect connection management.	Makes the connection hard to manage.
Failure Tolerance	High.	Low.
Scalability of Content Distribution	High (no need to modify any domain or architecture).	Limited (depends on overlay dedicated systems).
