Q. (a A Chord distributed hash table (DHT) with 26 address space is used in a peer-to-peer file sharing network. In this network, there are five active nodes with address (node ID) N5, N6, N10, N11 and N30. Node N30 shares files a.jpeg and b.jpeg with key k10 and k50, respectively. Descri node ID and key are derived Describe bricily how node ID and key are derived (2 marks) ii. Describe briefly how these sharing files are stored in this network if the indirect method is used. (3 marks) i What are the finger table of the nodes? (6 marks) iv Suppose that N11 needs to download the file b.jpeg. Describe how N11 finds the file. (6 marks) (b) HTTP supports two methods for clients to retrieve objects if the objects are located on the same server. Suppose that an HTTP client needs to access a file that contains one link to an image. The text file and image file are located on the same server. Describe how these files are retrieved using these two methods (8 marks) Q. (a A Chord distributed hash table (DHT) with 26 address space is used in a peer-to-peer file sharing network.
