This lightweight example shows the fundamental differences between TCP and UDP, including the trade-offs between reliability and performance in real-time applications. 🎯 Features Server Features (EG_UDP_Server_Chat.au3) 📡 Connectionless Communication - No persistent connections required 👥 User Registration - Track active users via keep-alive mechanism 📢 Broadcast Messages - Relay messages to all registered users ⏱️ Automatic Timeout - Remove inactive users (60 seconds) 💓 Keep-Alive System - PING/PONG protocol for user tracking 📊 User List Management - Dynamic user list with timestamps 🔍 IP Tracking - Monitor user IP addresses and ports ⚡ High Performance - Minimal overhead, fast message delivery 📝 Activity Logging - Track registrations, messages, and timeouts Client Features (EG_UDP_Client_Chat.au3) 🖥️ Simple GUI - Lightweight chat interface 📝 User Registration - Register with username and display name 👀 Active User List - View currently registered users 💬 Public Chat - Send messages to all registered users 💓 Automatic Keep-Alive - Send PING every 30 seconds 🔄 No Connection Required - Start chatting immediately after registration ⚡ Low Latency - Instant message delivery 🎨 Minimal UI - Focus on functionality 🗂️ File Structure EG_UDP_Server_Chat.au3 - UDP chat server application EG_UDP_Client_Chat.au3 - UDP chat client application 🔌 Protocol Documentation Message Format All UDP messages use pipe-delimited format: COMMAND|param1|param2|... Client → Server Messages Command Format Description REGISTER REGISTER|username|display_name Register client with server MSG MSG|username|message Send broadcast message PING PING Keep-alive heartbeat Server → Client Messages Message Format Description WELCOME WELCOME|client_count Registration successful REJECTED REJECTED|reason Registration rejected (duplicate name) USERLIST USERLIST|count|user1|user2|... List of registered users MSG MSG|from_user|message Broadcast message from user PONG PONG Keep-alive response 🆚 TCP vs UDP Comparison UDP Characteristics Feature UDP TCP Connection Connectionless Connection-oriented Reliability No guarantee Guaranteed delivery Ordering No guarantee Ordered delivery Speed Faster Slower Overhead Lower Higher Use Case Real-time data Reliable data transfer When to Use UDP ✅ Good for: Real-time gaming Voice/video streaming Live sports scores Sensor data transmission Quick status updates Broadcast notifications ❌ Not suitable for: File transfers Financial transactions Email/messages requiring delivery Database operations Critical data synchronization 🚀 Getting Started Starting the Server Run the server: ; Open EG_UDP_Server_Chat.au3 and run it Configure settings (in source): Global Const $SERVER_PORT = 9999 ; Change port if needed Global Const $USER_TIMEOUT = 60000 ; User timeout (60 seconds) Server binds to: Default port: 9999 IP: 0.0.0.0 (all interfaces) Starting the Client Run the client: ; Open EG_UDP_Client_Chat.au3 and run it Configure connection (in source): Global Const $SERVER_IP = "127.0.0.1" ; Server IP Global Const $SERVER_PORT = 9999 ; Server port Global Const $PING_INTERVAL = 30000 ; Ping interval (30 sec) Register with server: Enter username (must be unique) Enter display name Click "Connect" Server responds with WELCOME or REJECTED 📝 Usage Examples Basic Chat Flow 1. Server Startup: ; Server starts and binds to UDP port [SERVER] UDP Event Server v1.0.0 started [SERVER] Listening on port 9999 2. Client Registration: ; Client sends REGISTER message Client → Server: REGISTER|john|John Doe ; Server responds Server → Client: WELCOME|1 [SYSTEM] Registered successfully! 1 user(s) online. 3. Sending Messages: ; Client sends message Client → Server: MSG|john|Hello everyone! ; Server broadcasts to all registered users Server → All Clients: MSG|John Doe|Hello everyone! [John Doe] Hello everyone! 4. Keep-Alive: ; Client automatically sends PING every 30 seconds Client → Server: PING ; Server responds Server → Client: PONG 5. User Timeout: ; If client doesn't send PING for 60 seconds [SERVER] User 'john' timed out (no activity for 60s) ; Server removes user from active list 🔧 Configuration Options Server Configuration ; Network Settings Global Const $SERVER_PORT = 9999 ; Timeout Settings Global Const $USER_TIMEOUT = 60000 ; 60 seconds of inactivity Global Const $CLEANUP_INTERVAL = 10000 ; Check every 10 seconds ; User Limits Global Const $MAX_USERS = 100 ; Maximum registered users ; Performance Global $g_bDebugMode = False ; Enable for troubleshooting Client Configuration ; Connection Global Const $SERVER_IP = "127.0.0.1" ; Server address Global Const $SERVER_PORT = 9999 ; Server port ; Keep-Alive Global Const $PING_INTERVAL = 30000 ; 30 seconds ; Debug Global $g_bDebugMode = False ; Troubleshooting mode 📊 Key Functions Used Server Functions _UDP_Startup() - Initialize UDP system _UDP_Bind($sIP, $iPort) - Bind to UDP port _UDP_RecvFrom($hSocket, $iMaxLen) - Receive UDP packet Returns: [data, source_ip, source_port] _UDP_SendTo($sIP, $iPort, $sData, $hSocket) - Send UDP packet _UDP_CloseSocket($hSocket) - Close UDP socket _UDP_Shutdown() - Cleanup UDP system Client Functions _UDP_Startup() - Initialize UDP system _UDP_Bind("0.0.0.0", 0) - Bind to any available port _UDP_SendTo($SERVER_IP, $SERVER_PORT, $sData, $hSocket) - Send to server _UDP_RecvFrom($hSocket, $iMaxLen) - Receive from server _UDP_CloseSocket($hSocket) - Close socket 🔄 Keep-Alive Mechanism The UDP chat uses a keep-alive system to track active users: Client Server | | |--- REGISTER|user|name ------>| | | |<-------- WELCOME|count ------| | | | | +-- Every 30 seconds --------->| | PING | | | |<-------- PONG ---------------| | | | | +-- Server checks every 10s -->+ | Remove users inactive | | for more than 60s | Why Keep-Alive is Necessary: UDP is connectionless, so the server has no way to know if a client is still active unless the client periodically sends messages. The keep-alive system: Client sends PING every 30 seconds - Proves it's still active Server timestamps each message - Tracks last activity Server checks every 10 seconds - Removes users with >60s inactivity Automatic cleanup - Maintains accurate user list 🐛 Troubleshooting Common Issues Messages not delivered: Expected behavior - UDP doesn't guarantee delivery Solution - Use TCP for critical messages Mitigation - Implement application-level acknowledgments Messages arrive out of order: Expected behavior - UDP doesn't guarantee ordering Solution - Use TCP for ordered communication Mitigation - Add sequence numbers to messages User list not updating: Check PING interval vs server timeout Ensure PING messages are being sent Verify network connectivity Check firewall settings Can't register with server: Verify server is running Check IP and port settings Ensure username is unique Look for REJECTED message High packet loss: Check network quality Reduce message frequency Use TCP for important data Consider smaller packet sizes Debug Mode Enable detailed logging: Global $g_bDebugMode = True This outputs all UDP packets sent and received for troubleshooting. 🎯 Performance Characteristics Benchmarks Latency: < 1ms on local network Throughput: 10,000+ messages/second possible Packet Size: Up to 65,507 bytes per datagram Typical Usage: 100-500 bytes per chat message Memory: ~5-10 MB for client/server CPU: Minimal (<1% under normal load) Scalability Max Users: Limited by network bandwidth Recommended: 50-100 simultaneous users Message Rate: 10-100 messages/second per server Network Load: ~1-2 KB/s per active user ⚠️ Limitations & Considerations UDP Limitations No Delivery Guarantee Messages may be lost No automatic retransmission Application must handle loss No Ordering Messages may arrive out of order Application must handle reordering if needed No Connection State Server doesn't know if client exists Must implement keep-alive mechanism Firewall Issues Some firewalls block UDP NAT traversal can be problematic Security Considerations No Built-in Encryption - UDP packets are plaintext Spoofing Risk - Source IP can be forged No Authentication - Only username-based identification Broadcast Nature - All users see all messages Recommendations for Production: Add message encryption Implement authentication tokens Use digital signatures Consider hybrid TCP/UDP approach 🔬 Advanced Topics Implementing Reliability Add application-level acknowledgments: ; Client sends with sequence number _UDP_SendTo($SERVER_IP, $SERVER_PORT, "MSG|" & $iSeqNum & "|" & $sMessage, $hSocket) ; Wait for ACK Local $hTimer = TimerInit() While TimerDiff($hTimer) < 1000 ; 1 second timeout $aRecv = _UDP_RecvFrom($hSocket, 4096) If Not @error And StringLeft($aRecv[0], 3) = "ACK" Then ; Message acknowledged ExitLoop EndIf Sleep(10) WEnd Message Ordering Add sequence numbers: ; Server side - add sequence number to broadcasts Global $g_iMessageSeq = 0 _UDP_SendTo($sIP, $iPort, "MSG|" & $g_iMessageSeq & "|" & $sFrom & "|" & $sMsg, $hSocket) $g_iMessageSeq += 1 ; Client side - sort by sequence number ; Store messages and display in order NAT Traversal For internet deployment: Use STUN servers to discover public IP Implement hole punching for peer-to-peer Use relay server when direct connection fails Consider WebRTC for browser compatibility 📚 Related Examples See TCP Chat Example for reliable, ordered communication See Lab Manager Example for TCP-based remote administration 🎓 Learning Objectives This example demonstrates: UDP fundamentals - Connectionless communication Datagram handling - Sending and receiving discrete packets Keep-alive systems - Tracking active clients without connections Trade-offs - Speed vs reliability decisions Real-time communication - Low-latency messaging State management - Maintaining state without connection 🤝 Contributing Potential improvements: Add reliability layer - Implement ACK/NACK system Message encryption - Add AES encryption Voice chat - Integrate audio streaming File transfer - Chunked file transmission Private rooms - Multiple chat rooms User status - Typing indicators, online status Note: This example is designed for educational purposes and low-stakes real-time communication. For mission-critical applications requiring guaranteed delivery, use the TCP Chat Example instead. UDP is excellent for scenarios where speed is more important than perfect reliability.

WildByDesign Posted 2 hours ago Posted 2 hours ago 2 minutes ago, water said: Do you run the "AutoIt (Dark)" theme? The dark mode caused the unreadable text. Yes, you're right it is the theme that I've chosen in the forum. But I think that using a custom text color in a forum post is probably not a good choice though. I don't want to have to change the forum theme just to read certain posts. And this is actually a first that I've ever seen this happen.

argumentum Posted 2 hours ago Posted 2 hours ago .... ok @WildByDesign, good luck ? If you're gonna go "hard core dark mode" you're gonna have to "fix" those on your own. Follow the link to my code contribution ( and other things too ). FAQ - Please Read Before Posting.
argumentum Posted 2 hours ago Posted 2 hours ago That is how I see it. Hence my previous posts. I use Dark Reader extension. WildByDesign 1 Follow the link to my code contribution ( and other things too ). FAQ - Please Read Before Posting.
WildByDesign Posted 2 hours ago Posted 2 hours ago 2 minutes ago, argumentum said: If you're gonna go "hard core dark mode" you're gonna have to "fix" those on your own. I understand what you mean. And of course, I did end up selecting all of the text to read it on the day that it was originally posted. It's great content and great contribution with this UDF. But it was difficult to read when highlighted like that. I wouldn't really say it's "hard core dark mode" though because it isn't anything that was manually modified on the OS or browser level. It was just one of several themes that come with the forum software itself. These are all defaults that should just work. Also, it is the only thread/post on here that I have ever seen that is done this way. I assume that the problem is it's using some sort of copy/pasted HTML colors or custom text color of some sort. Things should really just follow what the OS/browser/forum software is set to. I just wanted to apologize though because I do not want to take away from @Trong's post and contributions which I am very thankful for. From my perspective, it is just a suggestion the ensure that things are readable by default. I will check out the Dark Reader extension as well. But it's still jumping through extra hoops to read something that should be readable initially.

If this forum had better themes and more formatting options I would agree but unfortunately none of that is there and a user is somewhat limited. On the other hand this post was formatted by AI and he just pasted it. Maybe pasting without formatting would do what you ask but would loose much of it's nice looking presentation. P.S.: It suck to come from the future @WildByDesign and having to wait for the past to catch up Edited 2 hours ago by argumentum WildByDesign 1 Follow the link to my code contribution ( and other things too ).

argumentum Posted 1 hour ago Posted 1 hour ago Forum in dark theme: vs. Dark Reader extension: So yeah, I use the default forum theme with the DarkReader extension that does what @Trong say the forum should have done for it's dark theme. 🤷♂️ Follow the link to my code contribution ( and other things too ).
