[Dev] vSRO Filter Architecture & Packet Handling

[MeDoSam]

Hello epvp community,

I've been studying Silkroad Online server architecture—specifically vSRO—and I am currently diving deep into the mechanics of custom security filters (similar in concept to early stFilter, bFilter, or modern proxy solutions).

Rather than looking for ready-made source code or leaked binaries, my primary goal is **educational and architectural understanding**. I want to properly learn how high-performance filters handle the pipeline between the client and `SR_ShardManager` / `SR_Client`.

### Core Topics I'm Focusing On:
1. **Network Layer & Proxy Architecture:**
- Best practices for socket handling (IOCP in C++ vs. modern .NET async pipelines).
- Minimizing latency during real-time packet inspection.
2. **Security & Protocol Handling:**
- Silkroad packet structure, handshakes, and Blowfish/Security token handling.
- Mitigating common exploit packets, packet spam, and malformed opcode injections.
3. **Client-Side Verification:**
- Establishing reliable heartbeats and basic integrity checks between the launcher/client hook and the proxy filter.

### What I Bring & What I'm Looking For:
I am actively coding and analyzing open implementations (such as SilkroadDoc/SilkroadSecurity libraries), but I’d love to connect with veterans who have built or maintained production filters.

If anyone is open to discussing architectural trade-offs, pointing out common design pitfalls, or sharing recommended reading/repos for network filtering in vSRO, I’d greatly appreciate your insights.

Feel free to share your thoughts here or reach out via PM / Discord if you're open to technical discussions.

Thanks for your time and respect for the dev scene!

How much progress have you made on your project? It would be great if you could show a few visuals of your work. I’m just curious. I’ve been developing my own project for years, too.
