What are the main arguments for adopting a super node approach in Skype?
What will be an ideal response?
The main reason for having super nodes is to implement efficient and reliable search, a key enabling function in Skype. Through this approach, search is supported only by nodes that have the required capabilities in terms of bandwidth, reachability and availability. The alternative is to adopt a pure peer-to-peer approach where all nodes cooperate to provide this function. The downside of this pure approach is that certain nodes involved in the implementation of search may be disconnected, or have weak connectivity in terms of bandwidth, leading to a more erratic service. The trade-off is that super nodes will encounter more traffic due to search, but they are selected on the basis they can absorb this.
