Infohashes are 160-bit and peers participating in Khashmir have a nodeID in the same 160-bit space. We discuss the Khashmir supplied with BitTorrent. The Khashmir supplied with BitTorrent has been adapted in order to be used as decentralized tracker and therefore differs from the original Khashmir. The standard BitTorrent also implements a DHT, called Khashmir, for swarm discovery. Note that a single DHT can be used for many torrents. When a peer starts downloading a torrent it adds its contact information in DHT and it does a lookup in the DHT to discover other peers in the swarm. torrent files can be used as the key and the list of peers that are downloading the torrents are used as value. Tracker can be replaced by using a distributed hash table (DHT) the infohashes of. The usual approach for swarm discovery is by using a central tracker. Do not forward request for very popular requests, but start replying.Scalable announce mechanism with intermediate peer tracking.Partial tracker for 6 golden peers and open TCP/IP connections.Use tracker and get_peers from PEX for golden peer discovery.No shared Max_Connections variable for swarm downloading and DHT connections.Create No_Max_Connections_Limiter for silent discarding peers.Dual cache lookup strategy for minimizing latency.Measure optimal bias which balances key distance and latency.Policy to bias Clean_Cache_Extension peers in some cases.recognize the Clean_Cache_Extension flag.Mechanism to implement enhancement flags in least significant bits.Include 8 closest matching peers in outgoing DHT messages.Peer Hit-probability based bucket size in Clean_Cache routing table.Routing table be 600 peers with roughly 10min average peer alive time.fixed maintenance rate of 1 packet per second, then Max.Exponential keep-alive period (1x1 minute,2x2,4x4,8x8,16x16,infinite x32) 5.8 hours increase time.Lazy routing table maintenance algorithm.Quarantine routing table for incoming candidates.IP spoofing and hijack prevention mechanism.Status: operational, but insufficient performance
