Peering Strategic Game Models for Interdependent ISPs in Content Centric Internet

Figure 1

Interdependent ISPs 𝐴₁, 𝐴₂, and 𝐴₃ build peering relationships between each other through cache-to-cache content sharing. Request queues for content 𝐶 within the three ISPs indicate intradomain popularity of content 𝐶. Both 𝐴₂ and 𝐴₃ cache the content 𝐶. 𝐴₁ does not cache 𝐶 but can receive it from 𝐴₂ or 𝐴₃.
