@@ -55,6 +55,19 @@ SessionManager.
- FTP Services: `FTPClient` and `FTPServer`
- HTTP Services: `WebBrowser` to simulate a web client and `WebServer`
- Fixed an issue where the services were still able to run even though the node the service is installed on is turned off
- NTP Services: `NTPClient` and `NTPServer`
- **RouterNIC Class**: Introduced a new class `RouterNIC`, extending the standard `NIC` functionality. This class is specifically designed for router operations, optimizing the processing and routing of network traffic.
- **Custom Layer-3 Processing**: The `RouterNIC` class includes custom handling for network frames, bypassing standard Node NIC's Layer 3 broadcast/unicast checks. This allows for more efficient routing behavior in network scenarios where router-specific frame processing is required.
- **Enhanced Frame Reception**: The `receive_frame` method in `RouterNIC` is tailored to handle frames based on Layer 2 (Ethernet) checks, focusing on MAC address-based routing and broadcast frame acceptance.
- **Subnet-Wide Broadcasting for Services and Applications**: Implemented the ability for services and applications to conduct broadcasts across an entire IPv4 subnet within the network simulation framework.
### Changed
- Integrated the RouteTable into the Routers frame processing.
- Frames are now dropped when their TTL reaches 0
- **NIC Functionality Update**: Updated the Network Interface Card (`NIC`) functionality to support Layer 3 (L3) broadcasts.
- **Layer 3 Broadcast Handling**: Enhanced the existing `NIC` classes to correctly process and handle Layer 3 broadcasts. This update allows devices using standard NICs to effectively participate in network activities that involve L3 broadcasting.
- **Improved Frame Reception Logic**: The `receive_frame` method of the `NIC` class has been updated to include additional checks and handling for L3 broadcasts, ensuring proper frame processing in a wider range of network scenarios.
### Removed
- Removed legacy simulation modules: `acl`, `common`, `environment`, `links`, `nodes`, `pol`
