tcpipstack

This project is based on the following courses:

• Part A - Networking Projects - Implement TCP/IP Stack in C
• Course Github: tcpip_stack

Despite of is based on the course above, you will be able different implementation because I decided to make some different logic to achieve the same goal. I put the course github if anyone wants to compare the implementation.

Test

In order to run all tests, you can run the following command:

$ make test

Print topology

In order to print topologies, you need to do the following steps:

1. Edit the main functon from the topologies.c file with the topology that you want:

// ...
int main() {
    // FirstTopology function is just an example. You can create new ones using the FirstTopology function as an example.
    graph_t *topology = FirstTopology();
    if (topology == NULL) {
        fprintf(stderr, "empty topology");
        return 1;
    }
    graph_GraphDump(topology);
    return 0;
}

2. Execute the following command:

$ make print-topology

Build Objects

If you want to build .o objects of the project, you can run the following command:

$ make build-objects

If you want to delete all .o objects execute the following command:

$ make clean
