开发日程（7.1-7.9）

1、本周进展

  • 阅读GT项目源码，主要关注了client/client.go和server/sever.go的启动流程和函数依赖关系；
  • 阅读论文《WiseTrans: Adaptive Transport Protocol Selection for Mobile Web Service》，关注QUIC和TCP在不同网络条件下的性能差异。

2、下周计划

  • 阅读并测试源码，找出并分析与“GT server 与 GT client 之间建立TCP连接”的相关函数；
  • 学习BBR拥塞控制算法。

Development schedule (7.1-7.9)

  1. This week's progress
  • Read the source code of the GT project, mainly focusing on the startup process and functional dependencies of client/client.go and server/sever.go;
  • Read the paper "WiseTrans: Adaptive Transport Protocol Selection for Mobile Web Service", pay attention to the performance difference between QUIC and TCP under different network conditions.
  1. Next week plan
  • Read and test the source code, find out and analyze the functions related to "establishing a TCP connection between GT server and GT client";
  • Learn BBR congestion control algorithm.

开发日程（7.10-7.16）

1、本周进展

  • 梳理GT项目中与Client-Server之间构建连接池的代码，找出关键函数并分析逻辑。主要关注Client端的c.connectLoop()->connect()->initConn()->dialFn函数链，关注Server端的listen()->acceptLoop()->handle()->handleTunnel()函数链，以及MagicNumber在区分流量中的作用；
  • 学习BBR拥塞控制算法，阅读了提出BBR算法的论文“BBR：Congestion-Based Congestion Control”。使用iperf3在Linux中测试了不同条件下Cubic和BBR的吞吐量，BBR在长肥网络（带宽时延积大、丢包率高）具有显著效果。

2、下周计划

  • 调研各种QUIC协议的开源实现，对比并挑选最合适的QUIC项目；
  • 测试相关函数的作用，尝试将QUIC协议嵌入GT项目。

Development schedule (7.10-7.16)

  1. This week's progress
  • Comb through the code of GT project with Client-Server to build connection pool, find out the key functions and analyse the logic. Mainly focus on the c.connectLoop()->connect()->initConn()->dialFn function chain of the Client side, on the listen()->acceptLoop()->handle()->handleTunnel() function chain of the Server side, and the MagicNumber's role in differentiating traffic;
  • Learn about the BBR congestion control algorithm and reading the paper "BBR: Congestion-Based Congestion Control" that proposed the BBR algorithm. Test the throughput of Cubic and BBR under different conditions in Linux using iperf3. Find that BBR has a significant effect in long fat networks (large bandwidth delay product and high packet loss).
  1. Next week plan
  • Research various open-source implementations of the QUIC protocol, compare and select the most suitable QUIC project;
  • Test the role of related functions and try to embed the QUIC protocol into the GT project.

开发日程（7.17-7.23）

1、本周进展

  • 调研各种QUIC的开源实现，主要关注quic-go（https://github.com/quic-go/quic-go ），msquic（https://github.com/microsoft/msquic ）和quiche（https://github.com/google/quiche ），因为这三个quic项目一直保持高频率维护。quic-go仅支持cubic拥塞控制算法（issue里面提到似乎不准备添加bbr算法），msquic和quiche均支持bbr；
  • 尝试寻找关键函数，因为比较熟悉quic-go而且函数接口对应，所以目前尝试先使用quic-go让gt支持quic，后续视情况选择使用cgo替换为quiche/msquic，又或者自行为quic-go增加bbr支持。

2、下周计划

  • 尝试基于quic-go实现gt对quic的支持。

Development schedule (7.17-7.23)

  1. This week's progress
  • Investigate various open source implementations of QUIC, focusing on quic-go (https://github.com/quic-go/quic-go), msquic (https://github.com/microsoft/msquic) and quiche (https://github.com/google/quiche), because these three quic projects have maintained high-frequency maintenance. quic-go only supports the cubic congestion control algorithm (it seems that the bbr algorithm is not planned to be added in the issue), and both msquic and quiche support bbr;
  • Try to find the key functions, because I am familiar with quic-go and the function interface corresponds, so try to use quic-go first to make gt support quic, and then choose to use cgo to replace quiche/msquic according to the situation, or add bbr support for quic-go myself.
  1. Next week plan
  • Try to implement gt's support for quic based on quic-go.

开发日程（9.4-9.10）

1、本周进展

  • 尝试将QUIC嵌入gt。但是QUIC的IO读写接口全部实现在stream结构中，而TCP的IO接口是现在connection结构中，因此需要对GT中connection层进行大量修改，于9.5开会进行讨论。
  • 在clinet.go以及client/conn.go中为QUIC撰写对应的处理函数，在server.go以及server/conn.go中为QUIC撰写对应的处理函数。

2、下周计划

  • 扩展conn/conn.go中的Connection结构，对齐QUIC的接口。
  • 基于quic-go实现gt对QUIC的支持。

Development schedule (9.4-9.10)

  1. Progress this week
  • Try embedding QUIC into gt. However, QUIC's IO read and write interfaces are all implemented in the stream structure, while TCP's IO interface is now in the connection structure, so a lot of modifications to the connection layer in GT need to be made, and a meeting will be held on 9.5 for discussion.
  • Write corresponding processing functions for QUIC in clinet.go and client/conn.go, and write corresponding processing functions for QUIC in server.go and server/conn.go.
  1. Plan for next week
  • Extend the Connection structure in conn/conn.go and align it with the QUIC interface.
  • Based on quic-go, gt supports QUIC.
