congestion: Move code to test module

2025-01-16T14:16:01Z

congestion: Some comments and mod syntax tweaking

2025-01-16T14:16:01Z

Don't put in the comments, let the top-level module comments do that job. Signed-off-by: David Goulet

congestion: Make a test_utils.rs

2025-01-16T14:16:01Z

Instead of having the congestion.rs test module public, make a test_utils.rs file that contains code for other unit tests within the congestion module. Signed-off-by: David Goulet

proto: Add Vegas congestion control algorithm

2025-01-16T14:16:01Z

The big one! This is the Vegas algorithm implementation that is hooked to the CongestionControl object by implementing the algorithm trait. Still, at this commit, nothing is being used by the circuit reactor yet. Related #534 Signed-off-by: David Goulet

proto: New CongestionControl object and fixed window algorithm

2025-01-16T14:16:01Z

Add the top level CongestionControl object that will allow the circuit reactor to use it in order to decide if a cell can be sent or not. In order to be used, it is configured with an algorithm that implements the CongestionControlAlgorithm trait. The Fixed Window algorithm is also added which essentially implements the SENDME logic as arti knows it today with a fixed window size. The SENDME code has been refactor in two different logical steps in order to accomodate the future Vegas algorithm for which the congestion window logic and SENDME validity is seperated. There is now a SENDME validator that takes care of tracking the tags (authenticated SENDMEs) and validating them upon reception. Then, if valid, the window management is passed down the congestion control algorithm, at this commit, FixedWindow object. Related #534 Signed-off-by: David Goulet

proto: Add generic objects for congestion control

2025-01-16T14:16:01Z

This commit adds the congestion window object, a round trip estimator (RTT) and a state enum. These 3 entities are used by congestion control in a generic way that is they are passed and used by any algorithm. At this commit, they are not used hence the allow deadcode attribute for now in order to minimize the build warnings. We also introduce the params.rs file containing the parameters, taken from consensus, used to configure these objects. They will be exposed to the tor-cirmgr crate to build the CircParameters. More will come. This also introduces the congestion/ directory that will contain more code in future commits. Related #534 Signed-off-by: David Goulet
