This example demonstrates how to create a minimal two-node client-server P2P network. The network consists of a Computer
and a Server on the same subnet with a single Link connecting the two.

The yaml file contains two nodes in the ``simulation.network.nodes`` array, one with the `pc_1` reference and another
with the `server_1` reference. both nodes are given a node type, `pc_1` being a `computer` and `server_1` being a
`server`. Both nodes are then given an ip address and subnet mask.
The link between the two nodes is configured in the ``simulation.network.links`` array, with the hostname and network
interface for each being configured under ``endpoint_<a or b>_hostname`` and ``endpoint_<a or b>_port`` respectively.

Node Configuration
^^^^^^^^^^^^^^^^^^
Each node in the network is defined with several attributes, crucial for determining its role and functionality within
the Network:
- **Hostname**: The hostname assigned to the node on the Network.
- **Type**: Specifies the role of the node (e.g., computer, server, etc.).
- **IP Address and Subnet Mask**: These settings define the network interface's IP configuration which is essential for
network communication.
Link Configuration
^^^^^^^^^^^^^^^^^^
The links section of the YAML configuration file specifies the physical connections between different network nodes
through their respective ports. This section is crucial for setting up the topology of the network, ensuring each node
is properly interconnected to facilitate communication and data transfer within the network. Each link in the network
is described with several attributes that define the connection between two endpoints:
- **endpoint_a_hostname**: The hostname of the first node in the connection.
- **endpoint_a_port**: The port number on the first node where the link is connected.
- **endpoint_b_hostname**: The hostname of the second node in the connection.
- **endpoint_b_port**: The port number on the second node where the link is connected.
Building the Config File
^^^^^^^^^^^^^^^^^^^^^^^^
**Defining the Network Scope and Scale**
1. **Identify the Participants**: The first step is to determine how many nodes are required and their roles. In this case,
we've chosen a simple two-node P2P architecture with one client (`pc_1`) and one server (`server_1`). This setup is
chosen to facilitate direct communication between a user (client) and a resource or service (server).
2. **Assign IP Addresses**: Choosing IP addresses that are within the same subnet (`192.168.1.x` with a subnet mask of
`255.255.255.0`) ensures that the two nodes can communicate without routing.
**Configuring Individual Components**
3. **Node Configuration Simplicity**: With only two participants, the network design is straightforward, focusing on direct
connectivity. Each node is configured with the minimal required settings: hostname, type, IP address, and subnet mask.
The simplicity ensures that the configuration is easy to understand and manage.
4. **Logical Assignment of Roles**: The computer is designated as the client and the server as the service provider. This
reflects typical real-world scenarios where a user's machine connects to a server that hosts resources or services.
**Configuring Connectivity**
5. **Direct Link Setup**: A direct link is planned between the two nodes. This is logical in a minimal setup where the
primary goal is to ensure efficient, high-speed communication between the client and the server. This direct
connection is configured through specified ports on each node, ensuring that these are the only two devices on this
segment of the network.
6. **Port Selection**: Choosing port 1 for both nodes for the connection might be based on convention or simplicity, as
typically, port numbering starts at 1. This makes it straightforward to follow and document.

#2. Basic Switched Network
--------------------------
Finally, once the network is configured as expected, a connectivity test should be carried out. This can be done by
"pinging" one node from another node. The below code block demonstrates how `pc_1` pings `server_1`.
In this example we'll create a basic switched network. The network will consist of two Computers, a Server, and a
Switch, all on the same subnet.

#2. Basic LAN
-------------
This example demonstrates setting up a basic Local Area Network (LAN) consisting of two Computers, a Server, a Switch,
and a Router, all configured on the same subnet. This type of network is commonly used in small office or home office
settings, providing shared access to resources like files and printers, while also offering a connection to the
internet through a router. This network provides a deeper dive into the new concepts introduced, including default
gateways, router configurations with ACLs, and port settings.

Node Configuration
^^^^^^^^^^^^^^^^^^
- **Type**: We now introduce two new node types, switch and router.
**Computers & Servers**
- **Default Gateway**: The IP address of the router that provides connectivity beyond the local network, essential for
accessing external networks.
**Routers & Switches**
- **Number of Ports**: Indicates how many physical connections the switch supports, which determines how many devices
can be connected.
**Routers**
- **Ports Configuration**: Each port on the router can be independently configured with an IP address and subnet mask,
important for managing different network interfaces.
- **Access Control Lists** (ACLs): Specifies rules that control the flow of traffic into and out of the router,
enhancing security by permitting or denying traffic based on source/destination IP addresses, and/or source/destination
ports, and/or protocol.
Building the Config File
^^^^^^^^^^^^^^^^^^^^^^^^
**Defining the Network Scope and Scale**
1. **Identify the Participants**: For the basic LAN, we have identified the need for two computers (pc_1 and pc_2), a
server (server_1), and networking devices including a switch (switch_1) and a router (router_1). This configuration
supports a typical small office environment where multiple users require access to shared resources and external
network connectivity (not configured in this network).
2. **Role Assignment**:
- **Computers** (`pc_1` and `pc_2`): Act as client systems for users to perform daily tasks and access shared
resources on the server.
- **Server** (`server_1`): Hosts resources such as files and applications needed by client systems.
- **Switch** (`switch_1`): Serves as the central hub connecting all nodes within the LAN to facilitate internal
network communications.
- **Router** (`router_1`): Would provide a gateway to external networks, routing traffic between the LAN and the
internet or other external networks.
**Configuring Connectivity**
3. **Switch Configuration**: The switch is configured with four ports to accommodate the two computers, the server, and
a connection to the router. This setup ensures all nodes are interconnected for seamless communication within the LAN.
4. **Router Setup as default Gateway**: The router is set up as the default gateway. It has one port that connects to
the switch.
5. **Security Settings with ACLs**:
- The ACL on the router (acl: 10) is configured to permit traffic from the specified internal IP range
(`192.168.0.0/24`) to access the router’s IP address (`192.168.1.1`). Essentially, this ACL allows the nodes in
the LAN to communicate with their default gateway (but no further at this stage).
6. **Physical Layout Planning**: Each node is strategically connected to the switch to minimise links and optimise
network performance. The computers (`pc_1` and `pc_2`) and the server (`server_1`) are each connected to individual
ports on the switch, maintaining an organised and efficient network topology.

Finally, once the network is configured as expected, a connectivity test should be carried out. This can be done by
"pinging" the default gateway of the server and computers (port 1 on `router_1`). Not only will this test the physical
connections, but the ACL that allows the nodes in the LAN to communicate with their default gateway.
.. code-block:: python
from primaite.simulator.network.networks import basic_lan_network_example
network = basic_lan_network_example()
pc_1 = network.get_node_by_hostname("pc_1")

To verify that the ACL on `router_1` worked, we can call `.acl.show()`. This not only shows the ACL rules, but the
number of times each rule has been hit. the code block below is an extension of the above code block that accesses the
`basic_lan_network_example`.

#3. Multi-LAN with Internet
---------------------------
This example presents an advanced network configuration that simulates a real-world scenario involving a home or office
network, an Internet Service Provider (ISP), and a comprehensive corporate network for a fictional company named
SomeTech. This extended network includes detailed sub-networks with specialised services, multiple routers featuring
complex routing capabilities, and robust security protocols implemented through Access Control Lists (ACLs). Designed
to mimic the intricacies of actual network environments, this network provides a detailed look at how various network
components interact and function together to support both internal corporate activities and external communications.

Node Configuration
^^^^^^^^^^^^^^^^^^
**Computers and Servers**
- **DNS Server**: Specifies the server that resolves domain names, which is crucial for accessing network services by
hostname instead of IP addresses. In this scenario, DNS servers play a vital role in connecting with external
internet services and internal applications.
**Routers & Firewalls**
- **Routes**: Routers also manage specific routes that direct traffic between subnets within the larger network. These routes are defined in the routing table and include:
- **IP Address**: The IP address of the destination node/subnet.
- **Subnet Mask**: Defines the size of the destination subnet and differentiates between network address and host identifier.
- **Next Hop IP Address**: The address of the next hop router or gateway that packets should be sent to when trying
to reach the destination subnet. This setting is essential for routing decisions in multi-network environments.
- **Default Route**: This is a crucial setting in complex network environments where multiple routers are used. It
directs outbound traffic to a specified gateway, typically used for accessing the Internet or connecting to upstream
networks.
**Firewalls**
- **Ports Configuration**: Similar to routers but with named ports to differentiate between external (internet-facing),
internal, and demilitarized zone (DMZ) connections.
