-# Potential avalanche from local lag
+# What to be concerned for internet syncing
+1. Server received too late (solution: force confirmation)
+2. Client received too late (solution: prediction and frame chasing, big impact on user experience because the graphics will be inconsistent if mismatches occur too often)
+
+# Potential avalanche from `ACTIVE SLOW TICKER`
 Under the current "input delay" algorithm, the lag of a single player would cause all the other players to receive outdated commands, e.g. when at a certain moment   
-- player#1: renderFrameId = 100, significantly lagged due to local CPU overheated
+- player#1: renderFrameId = 100, **still active in battle but significantly lagged** due to local CPU overheated
 - player#2: renderFrameId = 240
 - player#3: renderFrameId = 239
 - player#4: renderFrameId = 242
 
 players #2, #3 #4 would receive "outdated(in their subjective feelings) but all-confirmed commands" from then on, thus forced to rollback and chase many frames - the lag due to "large range of frame-chasing" would then further deteriorate the situation - like an avalanche.   
 
-In a "no-server & p2p" setup, I couldn't think of a proper way to cope with such edge case. Solely on the frontend we could only mitigate the impact to players #2, #3, #4, e.g. a potential lag due to "large range of frame-chasing" is proactively avoided in `<proj-root>/frontend/assets/scripts/Map.js, function update(dt)`.
+**BE CAUTIOUS, THIS `ACTIVE SLOW TICKER` SITUATION HAPPENS QUITE OFTEN FOR REAL DEVICES** where different operating systems and temporary CPU overheat cause different lags for different player in a same battle! If not properly handled, slow tickers would be `inputing in the "history" of other players`, resulting in too frequent prediction mismatch and thus inconsistent graphics for other players!
 
-However in a "server as authority" setup, the server could force confirming an inputFrame without player#1's upsync, and notify player#1 to apply a "roomDownsyncFrame" as well as drop all its outdated local inputFrames.

+# Would using UDP instead of TCP yield better synchronization performance?
+Yes, but with non-trivial efforts.
+
+## Neat advantage using UDP 
+Let's check an actual use case. As soon as an inputFrame becomes all-confirmed, the server should downsync it to all active players -- and upon reception loss of the packet containing this "all-confirmed downsync inputFrame" to a certain player, the server MUST retransmit another packet containing the same inputFrame to that player. 
+
+To apply UDP on this use case, additional `ack & retransmission mechanism` would be required, which is a moderately difficult task -- don't just pick a 3rd party lib using TCP flow-control alike `sliding window mechanism`, e.g. [RUDP](https://www.geeksforgeeks.org/reliable-user-datagram-protocol-rudp/)! Here's why. 
+
+Assume that the server is downsyncing `sequence of packets[#1, #2, #3, #4, #5, #6, #7, #8, #9, #10]`, when using TCP we get the advantage that each active player is guaranteed to receive that same sequence in the same order -- however in a bad, lossy network when `packet#2` got lost several times for a certain player whose reception window size is just 5, it has to wait for the arrival of `packet#2` at `[_, #3, #4, #5, #6]`, thus unable to process `[#7, #8, #9, #10]` which could contain `unpredictable inputFrame` while `#2` being `correct prediction` for that player.   
+
+That's so neat but still an advantage for using UDP! Yet if the TCP flow-control alike `sliding window mechanism` is employed on UDP, such advantage'd be compromised. 
+
+To summarize, if UDP is used we need 
+- an `ack & retransmission mechanism` built on top of it to guarantee reception of critical packets for active players, and 
+- reception order is not necessary to be reserved (mimic [markConfirmationIfApplicable](https://github.com/genxium/DelayNoMore/blob/v0.9.14/battle_srv/models/room.go#L1085) to maintain `lastAllConfirmedInputFrameId`), but 
+- TCP flow-control alike `sliding window mechanism` should be avoided to gain advantage over TCP. 
+
+## Additional hassles to care about using UDP
+When using UDP, it's also necessary to verify authorization of each incoming packet, e.g. by simple time limited symmetric key, due to being connectionless.
+
+## Why not hybrid?
+Instead of replacing all use of TCP by UDP, it's more reasonable to keep using TCP for login and the "all-confirmed downsync inputFrames" from server to players (and possibly "upsync inputFrames" from player to server, but tradeoff on that remains to be discussed), while using a `UDP secondary session` for broadcasting inputFrames of each individual player asap (either using p2p or not) just for **better prediction performance**!
+
+## How do you actually implement the `UDP secondary session`?
+It's not a global consensus, but in practice many UDP communications are platform specific due to their paired asynchronous I/O choices, e.g. epoll in Linux and kqueue in BSD-ish. Of course there're many 3rd party higher level encapsulated tools for cross-platform use but that introduces extra debugging when things go wrong.
+
+Therefore, the following plan doesn't assume use of any specific 3rd party encapsulation of UDP communication.

-![screenshot-1](./screenshot-1.png)
+This project is a demo for a websocket-based rollback netcode inspired by [GGPO](https://github.com/pond3r/ggpo/blob/master/doc/README.md). 
 
-Please checkout [this demo video](https://pan.baidu.com/s/1aM6e8IWaJszFCYAsRjt19g?pwd=z02c) to see whether the source codes are doing what you expect for synchronization.
+[Demo recorded over INTERNET (Phone-Wifi v.s. PC-Wifi UDP holepunched) using an input delay of 6 frames](https://pan.baidu.com/s/1UArwqDShLoPjYppjjqsTqQ?pwd=10wc), and it feels SMOOTH when playing!
 
-The video mainly shows the following feature (yet I'm not surprised if they're not obvious): when a player didn't have its input arrived at the backend in time (e.g. due to local lag, network delay or reconnection), backend forces confirmation of a prediction of its own and sends the confirmed input together w/ a reference render frame to that player.
+![Merged_cut_annotated_spedup](./charts/Merged_cut_annotated_spedup.gif)
+
+As lots of feedbacks ask for a discussion on using UDP instead, I tried to summarize my personal opinion about it in [ConcerningEdgeCases](./ConcerningEdgeCases.md) -- **since v0.9.25, the project is actually equipped with UDP capabilities as follows**.
+- When using the so called `native apps` on `Android` and `Windows` (I'm working casually hard to support `iOS` next), the frontends will try to use UDP hole-punching w/ the help of backend as a registry. If UDP hole-punching is working, the rollback is often less than `turn-around frames to recover` and thus not noticeable, being much better than using websocket alone. This video shows how the UDP holepunched p2p performs for [Phone-Wifi v.s. PC-Wifi (viewed by PC side)](https://pan.baidu.com/s/1K6704bJKlrSBTVqGcXhajA?pwd=l7ok).
+- If UDP hole-punching is not working, e.g. for Symmetric NAT like in 4G/5G cellular network, the frontends will use backend as a UDP tunnel (or relay, whatever you like to call it). This video shows how the UDP tunnel performs for [Phone-4G v.s. PC-Wifi (viewed by PC side)](https://pan.baidu.com/s/1IZVa5wVgAdeH6D-xsZYFUw?pwd=dgkj). 
+- Browser vs `native app` is possible but in that case only websocket is used.
+
+
+# Notable Features
+- Backend dynamics toggle via [Room.BackendDynamicsEnabled](https://github.com/genxium/DelayNoMore/blob/v0.9.14/battle_srv/models/room.go#L786)
+- Recovery upon reconnection (only if backend dynamics is ON)
+- Automatically correction for "slow ticker", especially "active slow ticker" which is well-known to be a headache for input synchronization
+- Frame data logging toggle for both frontend & backend, useful for debugging out of sync entities when developing new features

+The `-vsync vfr` tells ffmpeg to disrespect the original delays set within the GIF file, otherwise many duplicate frame will be extracted by the default 60FPS.
+
+More complicated transparent padding example (used when alignment in image source is much more preferred than aligning in codes) 
+```
+ffmpeg -vsync vfr -i LayDown1.gif -vf "scale=iw:188:force_original_aspect_ratio=decrease,pad=iw:188:0:(oh-ih):color=#00000000,format=rgba" pngs/LayDown1_%d.png
