Should be put in the compilation in both the Makefile and CMakeLists.txt

Depends on the behaviour of the simulation process, but a signal for simulation done is likely to be needed.

Remove a Node from the GUI and handle it in the BGP protocol (fault router)

• If you try to build the docs locally, it is not guaranteed that the user has sphinx-build installed.
  Error:

/bin/sh: line 1: sphinx-build: command not found
make: *** [Makefile:20: docs] Error 127

(I cannot understand why the Makefile is using the /bin/sh shell instead of the shell in my environment

• If you try to build the docs on Docker neither the command docs nor build are found. Only the command clean is present (take a look at the Makefile)
  Error:

Here we have to discuss how to simulate the packet transmission.
E.g.:

1. GUI -> Send "transmit the first packet"
2. Backend computes the behaviour
3. Backend returns the path of the first packet
4. GUI -> shows the behaviour

OR

1. Backend computes all the paths for the packets (including various events)
2. GUI -> Show all the packets' behaviour without interruptions

Since you are already parsing the configuration file, it would be nice to have a bool variable that I can test and which is saying if a device is a router or endpoint (it can be also a Char indicating the type)

Set a new link from the GUI and handle it in the BGP protocol

For example the cmake version in the Dockerfile

• Device
  Abstact type: can be Router or Client

  • ID (internal, just needed for the simulation)

• Router

  • ID → see Device
  • AS number
  • networks_details[] (derived from Network_details)
  • links[] (derived from Link)
  • announced prefixes[]
  • localPreference[]
    • AS, preferenceValue
  • trust[]
    • AS, trustValue

• Client

  • ID → see Device
  • network_details (derived from Network_details)
  • link (derived from Link)

• Network_details

  • interface
  • IP
  • netmask
  • default_gateway

• Link

  • device_ids(x, y)
  • device_source_interfaces(x, y)
  • connectionStatus (failed/active)

Find out a proper library to create and handle TCP/IP packets.
Requirements:

• packet manipulation at a bit level
• the router must check the header of the packet to forward it
• fragmentation optional
• IPv6 optional

The link status is stated with an enum, but the correspondent bool is probably wrong.
Behaviour:

active -> 0
failed -> 1

The other way around could be more intuitive returning true when the link is active

Trying to build the docs with docker, gives the following error:

docker: Error response from daemon: create ./docs: "./docs" includes invalid characters for a local volume name, only "[a-zA-Z0-9][a-zA-Z0-9_.-]" are allowed. If you intended to pass a host directory, use absolute path.

Delete a link from the GUI simulation and handle it in the BGP Protocol
