A library for reliable data transfer service on top of the UDP protocol that supports loadbalancing and reverse proxy features which loadbalances client requests on the servers and also caches the files at the proxy to decrease response time to the clients and reduces the load on the backend servers. The loadbalancer also works with the reliable data transfer service on top of the UDP. The library simulates packet loss and packet corruption and handles these issues for reliability.



Installation

You can use go get to install to your $GOPATH, assuming that you have a github.com parent folder already created under src:

  1. $ go get -t github.com/mohamedmahmoud97/Zuper-UDP

Usage

  1. $ go run examples/loadbalancer/loadbalancer.go sr
  3.  _ _ _                          _    _ ___   _ __
  4. |_ _  | _   _ _ __   ___  _ __ | |  | |._ \ | ._ \

Test it

You can test the server-client library with running any of the bash files: gbn.sh for testing GoBackN algorithm, sr.sh for SelectiveRepeat, and sw.sh for Stop-and-Wait. You can also change the parameters for the client, the server, and the loadbalancer in device_info/client.in and device_info/server.in, and device_info/loadbalancer.in. If you want to neglect the simulation probability packet loss just change last attribute in server.in to 0.

You can also test the loadbalancer by running go run examples/loadbalancer/loadbalancer.go and run some servers by running go run examples/server/server.go sr and run client to request files by running go run examples/client/client.go sr, but don’t fforget to change the server address attribute for all clients is the address of the loadbalancer.

For Client

  1. 127.0.0.1            IP address of server
  2. 10066                Well-known port number of server.
  3. 127.0.0.1            IP address of client.
  4. 10044                Port number of client.
  5. test.pdf             Filename to be transferred.
  6. 5                    Initial receiving sliding-window size (in datagram units).

For Server

  1. 127.0.0.1            The IP address of server
  2. 10066                Well-known port number for server.
  3. 5                    Maximum sending sliding-window size (in datagram units).
  4. 5                    Random generator seedvalue.
  5. 0.3                  Probability p of datagram loss (real number in the range [ 0.0 , 1.0 ]).

For Loadbalancer

  1. 127.0.0.1:10000                The IP address of loadbalancer
  2. 127.0.0.1:10001                The IP address of first server
  3. 127.0.0.1:10101                The IP address of second server
  4. 127.0.0.1:10201                The IP address of third server
  5. 127.0.0.1:10301                The IP address of fourth server
  6. 127.0.0.1:10401                The IP address of fifth server
