Onion Services + +Onion service requires us to advertise the protocol version and congestion +control parameters in a different way since the end points do not know each +other like a client knows all the relays and what they support. + +To address this, this is done in two parts. First, the service needs to +advertise to the world that it supports congestion control. This is done +through a new line in the descriptor, see section 9.1 below. + +Second, the client needs to inform the service that it wants to use congestion +control on the rendezvous circuit and with wich parameters.

Descriptor + +We propose to add a new line to advertise the flow control protocol version: + + "flow-control" SP version-number NL + + The "version-number" value is the same as the protocol version FlowCtrl + that relay advertises which is defined earlier in this proposal. Current + value can only be "2". + +Clients that are able to parse this line and know the protocol version can then +send in the INTRODUCE1 cell congestion control parameters that they would like +to use which is detailed in the next section. + +9.2 INTRODUCE cell extension + +We propose a new extension to the INTRODUCE cell which can be used to send +congestion control parameters down to the service. It is important to mention +that this is an extension to be used in the encrypted setion of the cell and +not its readable section by the introduction point. + +If used, it needs to be encoded within the N_EXTENSIONS field of the ENCRYPTED +section of the INTRODUCE1 cell defined in rend-spec-v3.txt section 3.3. The +content is defined as follow: + + EXT_FIELD_TYPE: + + [01] -- Congestion Control Parameters. + + If this flag is set, the extension should be used by the service to learn + what are the congestion control parameters to use on the rendezvous + circuit. + + EXT_FIELD content format is: + + N_PARAMS [1 byte] + N_PARAMS times: + PARAM_TYPE [1 byte] + PARAM_VALUE [8 byte] + + The PARAM_TYPE possible values are: + + [01] -- Newest protocol version supported + The newest protocol version that the client supports. + + [02] -- SENDME increment + The initial SENDME increment that should be used by both end points + when using congestion control. + + The PARAM_VALUE size is 8 bytes in order to accomodate 64bit values. It + MUST match the specified limits for the following PARAM_TYPE: + + [01] -- Min: 2, Max: 255 + [02] -- Min: 1, Max: 5000 (same as "cc_sendme_inc") + +9.3 Protocol Flow + +First, the client reads the "flow-control" line in the descriptor and gets the +maximum value from what it supports and the service supports. As an example, if +the client supports 2-3-4 and the service supports 2-3, then 3 is chosen. + +It then sends that value along its desired cc_sendme_inc value in the +INTRODUCE1 cell in the extension. + +The service will then validate that is does support version 3 and that the +parameter cc_sendme_inc is within range of the protocol. Congestion control is +then applied to the rendezvous circuit. + +9.4 Circuit Behavior + +If the extension is not found in the cell, the service MUST not use congestion +control on the rendezvous circuit. + +Any invalid values received in the extension should result in closing the +introduction circuit and thus not continuing the rendezvous process. An invalid +value is either if the value is not supported or out of the defined range. + +9.5 Security Considerations + +Advertising a new line in a descriptor does leak that a service is running at +least a certain tor version. We believe that this is an acceptable risk in +order to be able for service to take advantage of congestion control. Once a +new tor stable is released, we hope that most service upgrades and thus +everyone looks the same again. + +The new extension is located in the encrypted part of the INTRODUCE1 cell and +thus the introduction point can't learn its content. + +10.
