Everyone is invited to attend his talk. The talk title and abstract follow below:
Network Management Architecture for Delivering Cloud Services
Efficient and reliable networks are critical to good end-to-end performance
of cloud services. In both the datacenters of cloud providers and the ISPs
connecting clients, many network management applications were built to
improve efficiency and reliability.
However, the traditional way of building management applications is not
sustainable, relying on heavy human involvement. Software-defined
networking (SDN) promises to simplify programming management applications.
Yet SDN's current scope is limited to routing control on network devices
within a single domain.
My research works explore expanding the concept of SDN for better
end-to-end performance of cloud services. In the exploration, I take a
research approach of achieving and balancing three objectives: 1) design
simple and expressive programming abstraction, 2) build efficient and
scalable system for execution, and 3) deploy and run in real world.
Using this research approach, I have explored three directions.
The first direction is deep into network devices to make infrastructure
easy to program. The network operating system I built, called Statesman,
introduces a three-view-of-network-state abstraction for programming a wide
range of management applications. Besides the abstraction, Statesman
enables automatic and safe operation of multiple applications in parallel.
Published in SIGCOMM'14, Statesman has been deployed and operational
worldwide in Microsoft Azure for over one year.
The second direction is expanding into servers in datacenters to leverage
the fine-grained knowledge of cloud services in the server OS. The system,
called HONE, offers a three-stage programming framework to simplify traffic
management. HONE's runtime executes the programs across servers and network
devices in an efficient and scalable fashion. HONE has been integrated into
products for Verizon Business Cloud, and appeared in JNSM July'14.
The final direction is reaching out to ISPs for better delivery of cloud
services. This work-in-progress aims at a direct, fine-grained, and
self-contained solution to inbound traffic engineering (TE) for
enterprises. The solution employs three tiers of abstractions to simplify
the inbound-TE policies, and it scales up with a distributed enforcement
system to control the inbound ISPs for traffic flows. This ongoing work is
in collaboration with OIT on our campus network.
