Optimizer

Optimizer

Optimizer is a pluggable transport that uses one of several possible “Strategies” to choose between the transports you provide to create a connection. It is not a standalone transport, but is rather a mechanism for choosing between various transports in order to find the one best suited for the user’s needs. For more information about pluggable transports, please refer to pluggabletransports.info.

Here is a list of the currently available Optimizer strategies:

Rotate Strategy: This strategy simply rotates through the list of provided transports and tries the next one in the list each time a connection is needed.

Choose Random Strategy: A transport is selected at random from the list for each connection request.

Track Strategy: A strategy that attempts to connect with each of the provided transports. It keeps track of which transports are connecting successfully and favors using those.

Minimize Dial Strategy: The transport is chosen based on which has been shown to connect the fastest.

Using Optimizer

Go Version:

Optimizer is one of the transports available in the Shapeshifter-Transports library.

1. First you will need to initialize the transports you would like Optimizer to use: dialer := proxy.Direct obfs4Transport := obfs4.Transport{ CertString: "InsertCertStringHere", IatMode: 0 or 1, Address: "InsertAddressHere", Dialer: dialer, } shadowTransport := shadow.Transport{"InsertPasswordHere", "InsertCipherNameHere", "InsertAddressHere"}

2. Create an array with these transports: transports := []Transport{obfs4Transport, shadowTransport}

3. Initialize the strategy of your choice using the array of transports you created: strategy := NewMinimizeDialDuration(transports)

4. Create an instance of OptimizerConnectionFactory using your new Strategy instance: optimizerTransport := NewOptimizerClient(transports, strategy)

5. Call Dial on optimizerTransport: _, err := optimizerTransport.Dial()
