15) The Metrics Project aims at measuring various aspects of the Tor network,
16) including both contributed resources and network usage. These information
17) are important, e.g., for deciding what parts of the network require more
18) support to better meet user needs.

27) <li><b>Relays:</b> There are already statistics covering the data that
28) relays report about themselves and which are confirmed in parts by the
29) directory authorities. The <a
30) href="http://torstatus.kgprog.com/">TorStatus</a> project evaluates the
31) hourly published directories containing lists of all running relays and
32) keeps track of their uptimes and advertised bandwidths. However, an
33) aggregate view of the development of relays over an extended period of time
34) is still missing. In addition to that, all information about provided
35) bandwidth capacity as reported by the relays is not necessarily
36) trustworthy. There has not been a comprehensive measurement of relay

38) <li><b>Bridges:</b> A special type of relays is running as bridges. Bridges
39) are relaying traffic, too, but are not listed in the public directory. The
40) purpose of bridges is to allow censored clients to connect to the Tor
41) network without their censor being able to prohibit access easily. The
42) number and capacity of bridges is therefore not publicly known and has not

44) <li><b>Clients:</b> Little is known about usage of the Tor network. In
45) particular, the number and location of clients are largely unknown. A rough
46) estimation is that there are a few hundreds of thousands of clients in the
47) network; a number which is very hard to verify. There are no recent studies
48) on the number of Tor users which would help obtaining a better picture on
49) usage of the Tor network. Clearly, all investigations of clients need to be

56) to August 2011 (see section 5.7 of the <a
