every client is also a serverEvery client maintains networkSearches traverse the network to a defined depthCSE333CSE333 DDS.6Step 1:Step 1: Pick a subset of existing DDSs Pick a subset of existing DDSsBitTorrent was chosen because it is exotic.BitTorrent was chosen because it is exotic.It does not behave like any other peer-to-peer file sharing system.Very large files are broken into small pieces which are “held together” by .torrent files, which contain information about the files.A new solution to the problem of transferring large files over the InternetDirect Connect was chosen because it represents a simple Direct Connect was chosen because it represents a simple peer-to-peer system that utilizes it's own non-standard peer-to-peer system that utilizes it's own non-standard protocol.protocol.Clients connect to a hub, where they search for other client's files and then directly connect.Maintains security, restricting certain functions on the hub from non-“Op” users.CSE333CSE333 DDS.7ProcessProcessStep 1:Step 1: Pick a subset of existing DDSs Pick a subset of existing DDSsStep 2:Step 2: Determine main common components Determine main common componentsStep 3:Step 3: Break up the components within each DDS Break up the components within each DDS into disjoint entities.into disjoint entities.Step 4:Step 4: Combine the breakdowns of the different Combine the breakdowns of the different DDSs together within each componentDDSs together within each componentStep 5:Step 5: Determine a set of attributes, and tag Determine a set of attributes, and tag inheritance lines with theminheritance lines with themStep 6:Step 6: Create an architecture based on a set of Create an architecture based on a set of given attributes in which to customizegiven attributes in which to customizeStep 7:Step 7: Analysis, Conclusions, Problem summary, Analysis, Conclusions, Problem summary, and moreand moreCSE333CSE333 DDS.8Step 2: Determine main common componentsFTPLimewireDirectConnectBitTorrent1.
