End-2-End Zero Trust Network Security Framework
Abstract: Latest trends of global 5G launch, microservices adoptions and exponential growth of remote work-force due to Covid-19 are moving computation powers out of enterprise data centers on to multiple clouds and edges. Consequently, the surface prone to attack is growing astronomically in the years ahead. Traditional network access control implementations are usually fragmented, lacking single source of truth for ongoing verification, hard to automate and very costly to maintain. Cisco has developed an end-to-end zero trust network security framework, based on programmable infrastructure and machine learning techniques, to enforce and to continually assure security policies are in place from work-force, via work-place to ultimately work-loads.
Speaker Bio: Philip Wong is the Principal Solution Architect of Cisco Greater China, leading Multi-Cloud & Zero Trust Security solution development endeavors in the region. Since joined Cisco in 2006, Philip has been an active practitioner and thought leader in SDN, IoT and network security. Before joining Cisco, Philip had 15 years+ experience in delivering innovative banking solutions during his tenture with Microsoft and IBM HK. Philip is a vintage computers collector and was interviewed by CNN, Phoenix and other newspapers on his collections.

Accelerating Distributed DNN Training with BytePS
Abstract: Deep Neural Networks (DNN) have made breakthroughs in many fields including Speech, Computer Vision, Natural Language Understanding, and Content Recommendation. The DNN models behind those breakthroughs can have tens to hundreds of layers, with hundreds of millions or even more parameters. Training those deep models costs a huge amount of computational power, and the training process lasts days to weeks. In this talk, I will introduce BytePS for distributed DNN training acceleration. BytePS provides a unified and optimal communication framework which includes Parameter Server and all-reduce as two special cases. To achieve the proved optimality in practice, BytePS further uses several key technologies including RoCEv2 acceleration and gradient partitioning and scheduling. BytePS supports major training frameworks including TensorFlow, PyTorch, and MXNet. BytePS has been widely adopted in Bytedance and other companies, for DNN training up to several hundreds of GPU cards.
Speaker Bio: Chuanxiong Guo is a director of Bytedance AI Lab. Before that he was a Principal Researcher at Microsoft Research. He is currently working on data center networking and machine learning systems. Several of his envisions including DCN virtualization, DCN monitoring, and ServerSwitch generated both academic and industrial impacts. Several of the systems that he designed and implemented, including Pingmesh and RDMA/RoCEv2 were widely adopted by the industry. He is interested in building, running, and understanding computer systems with high availability at scale.

Scalable and Elastic Routing Service for Tencent Cloud
Abstract: With more and more enterprise services are deployed on cloud, we found that the dominant solution for the cloud access scenarios, which leverages traditional commodity routers, is hard to scale and evolve to meet the new challenges at low cost including high volume traffic, massive scale routing table/ACL and fine-grained traffic engineering. To address these challenges , we split cloud router functionalities into several components including commodity-switch for underlay network inter-connection, server-based packet processing clusters for data plane, server-based routing cluster for routing protocol, hierarchical and efficient message distribution system for control plane, and programmable switches for hardware acceleration. With this new design, each component can be scaled, maintained, upgraded, bug fixed independently as needed. We managed to provide Tencent cloud a highly scalable, elastic and cost-efficienct cloud routing service.
Speaker Bio: Allen Lv is the Chief Architect of Tencent Cloud. He is working on cloud networking and data center networking.

Talk Title:
Reliability and Performance in Azure Data Center Networks
Abstract: Azure public cloud is one of the largest in the world, and networking is its backbone. This talk will focus on two areas of critical importance for us: reliability and performance. I will first describe cutting-edge network verification technology we use to ensure that Azure Network continues to perform reliably in the face of constant churn. I will then discuss deployment of Remote Direct Memory Access (RDMA) technology in Azure. Azure now has one of the largest deployments of RDMA in the world. I will discuss how it improves performance for our customers, and lowers costs for us. I will also touch upon various lessons learnt as we deployed RDMA on a scale never before attempted.
Speaker Bio: Jitendra Padhye is a Partner Development Lead at Microsoft Azure networking. He is interested in all aspects of computer networking and networked systems. His recent work has focused on data center networks and mobile computing. He has published numerous research papers in top conferences, and holds over 25 US patents. He is the recipient of the ACM SIGCOMM’s Test of Time award. He received his PhD in Computer Science from University of Massachusetts Amherst in 2000.
