A Novel Fog Computing Based Architecture to Improve the Performance in Content Delivery Networks
Table 1
Comparison of information-centric and host-centric networking.
| ā | 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). |
