Overview. - - Tor directory authorities hourly vote and agree on a consensus document - which lists all the routers on the network together with some of their - basic properties, like if a router is an exit node, whether it is - stable or whether it is a version 2 directory mirror. - - One of the properties given with each router is the 'Running' flag. - Clients do not use routers that are not listed as running. - - This proposal suggests that routers without the Running flag are not - listed at all. - -2. Current status - - At a typical bootstrap a client downloads a 140KB consensus, about - 10KB of certificates to verify that consensus, and about 1.6MB of - server descriptors, about 1/4 of which it requires before it will - start building circuits. - - Another proposal deals with how to get that huge 1.6MB fraction to - effectively zero (by downloading only individual descriptors, on - demand). Should that get successfully implemented that will leave the - 140KB compressed consensus as a large fraction of what a client needs - to get in order to work. - - About one third of the routers listed in a consensus are not running - and will therefore never be used by clients who use this consensus. - Not listing those routers will save about 30% to 40% in size. - -3. Proposed change - - Authority directory servers produce vote documents that include all - the servers they know about, running or not, like they currently - do. In addition these vote documents also state that the authority - supports a new consensus forming method (method number 4). - - If more than two thirds of votes that an authority has received claim - they support method 4 then this new method will be used: The - consensus document is formed like before but a new last step removes - all routers from the listing that are not marked as Running. - |
