About Me

Hi! I am Yunkun Liao (廖云坤), a 5th year Ph.D Student at ICT, CAS, advised by Prof. Guihai Yan. Currently, I am doing research in the intersection between computer network and computer architecture (computing-network convergence, “算网融合” in Chinese). I am expected to graduate in 2026/01.

Google scholar I hope to continuously improve the quality of my research.

For research, try to think big, aim high, act bold and make positive changes.

For people around me, try to make Good Thoughts, Good Words, Good Deeds.

For the life journey, I believe He who has a why to live can bear almost any how. (Friedrich Nietzsche).

算网融合

网中有算

数据中心Scale-Out, Disaggregation是未来算力增长的关键路径，网络基础设施应足够强、以释放大规模算力。 （对网络基础设施“强”的定性：释放大规模算力需要网络基础设施具备“远程访问本地化”、“硬件资源虚拟化”、“安全防护内联化”，“运行维护集约化”。）

算中有网

一种新的计算编排方式，打破传统算力设备和网络设备的边界，在网络设备中融合计算和传输以提升计算效率，实现在网计算。

生命，一次又一次轻薄过 轻狂不知疲倦 　　 ——题记

我听见回声，来自山谷和心间 以寂寞的镰刀收割空旷的灵魂 不断地重复决绝，又重复幸福 终有绿洲摇曳在沙漠 我相信自己 生来如同璀璨的夏日之花 不凋不败，妖冶如火 承受心跳的负荷和呼吸的累赘 乐此不疲 　　

我听见音乐，来自月光和胴体 辅极端的诱饵捕获飘渺的唯美 一生充盈着激烈，又充盈着纯然 总有回忆贯穿于世间 　　 我相信自己 死时如同静美的秋日落叶 不盛不乱，姿态如烟 即便枯萎也保留丰肌清骨的傲然 玄之又玄

我听见爱情，我相信爱情 爱情是一潭挣扎的蓝藻 如同一阵凄微的风 穿过我失血的静脉 驻守岁月的信念

我相信一切能够听见 甚至预见离散，遇见另一个自己 而有些瞬间无法把握 任凭东走西顾，逝去的必然不返 　　 请看我头置簪花，一路走来一路盛开 频频遗漏一些，又深陷风霜雨雪的感动

般若波罗蜜，一声一声 生如夏花，死如秋叶 还在乎拥有什么
