Hi Lichun, Section 9 "Overlay Optimize Example" is an example of optimizing data flow trafic if the overlay is constructed and running by carriers. As carriers know the the network infrastructure topology( the backbone networks infrastructure), they can construct the overlay by domains, and the data flow in one domain will not across over backbone networks, that can limit the data flow across over backbone networks. Normally, the domains are constructed by region.
For the detail usage of content storing by domain based overlay, there are many methods. For instance, the content provider can distribute the content to each domain of the overlay, the resource ID is generated by domain ID(Can be identified by carriers or May hash by domain name) plus generic ID( e.g. hashed by resource name). Here, the domain ID is the identity of one domain, and all the node IDs and resource IDs in one domain are generated by domain ID plus IDs constituted by the specific rule and hash algorithm . When one CSC(Content Sharing Client) wants to fetch resource, it generates the resource ID by same rule such as domain ID plus ID(e.g. hashed by resource name) and gets the resource from the peer in same domain. Thanks.

Can you give more details about the multi-domain overlay architecture? For example, which content is stored in which domain?
