Research Statement
As the Internet infrastructure continues to expand, no doubt it will have physical reach to
every remote corner of the
world and possess impressive raw communication capacity. However, for the Internet to truly
fulfill its social and economic
promises in the long run, the Internet's enormous and growing complexity must be made
tractable. For example, the Internet's
network structure, traffic processing behavior, and failure modes are all highly complex.
Consequently, applications often
perform sub-optimally, network operators often make grave mistakes, and failures are often
hard to diagnose. Addressing
the fundamental complexity challenges in the Internet will require the development of new
models that provide simple yet
accurate abstractions, new algorithms that take advantage of the simplifying models, and new
systems that bridge the gap
between theory and practice. In the following, I will describe my work on network coordinate,
network operating system, and
network self-verification that aims to address the structural, behavioral, and failure-mode
complexity challenges.
Since the vast Internet structure is beyond anyone's knowledge, application developers have
relied on heavy-weight, all pair
network measurements to determine network performance. However, through large-scale
studies of the end-to-end delay
properties of the Internet, I discovered the surprising result that the Internet delay metric
space has a low inherent dimensionality
and can be closely approximated by a low dimensional Euclidean model. Applying this insight,
I have developed
a network coordinate system called Global Network Positioning (GNP) to provide light-weight
and scalable network performance
prediction. In GNP, each Internet host independently performs delay measurements against
tens of other Internet hosts
and uses these measurements to compute numerical coordinates to describe its position in the
Internet delay space. These
coordinates provide a highly scalable means for predicting the end-to-end delay between any
pair of hosts. I have developed
novel distributed algorithms that enable Internet hosts to compute stable and secure
coordinates in a scalable manner with no
central coordination. I have developed a peer-to-peer video streaming system that
demonstrates GNP's benefits for performance
optimization. Many other researchers have also adopted GNP and independently demonstrated
its benefits. Currently,
I am working on new challenges in exploiting network coordinates and delay space properties:
e.g., to construct scalable
Internet simulation models, to detect inefficient Internet routing problems, and to infer the
network locations of mis-behaving
hosts.
The traffic processing behavior of the Internet is rapidly increasing in complexity as new
functions (e.g. detecting and
blocking unwanted traffic, balancing network and server load, enabling virtual private
networking, etc.) are shoehorned
into the network. Worse, each function is often naively managed in isolation even though the
various functions inevitably
interact in the underlying network. Accidental interactions among functions can cause
misbehaviors that have catastrophic
consequences (e.g. security breach, global routing instability, SLA violation, etc.). To address
this behavioral complexity, I
have developed the Directed Acyclic Graph (DAG) model for expressing the communication,
scheduling, and concurrency
requirements among network functions. Furthermore, I have developed a network operating
system called Maestro that
directly controls the behavior of the routers in an autonomous network and orchestrates
network functions based on the
DAG model. Maestro provides abstract views of the underlying network state and allows
network functions to be realized
as simple application programs that process and modify the abstract views. Actual router state
updates are performed by
Maestro via a robust and secure communication protocol called MMS. An operator can use the
DAG model to precisely
compose elementary applications to realize sophisticated functions. Maestro enforces the
communication, scheduling, and
concurrency requirements among applications. Critical network operational invariants (e.g.
network load, loop freedom,
etc.) are also enforced by Maestro. Moreover, by statically analyzing the system
configurations, harmful control feedback
loops can be proactively identified. Currently, I am extending Maestro to take advantage of
the robust autonomous properties
provided by distributed protocols (e.g. routing protocols like OSPF & BGP), and to allow
Maestro to be distributed over
multiple servers. I believe Maestro transcends today's ad hoc network control systems, and its
approach can potentially lead
to a new market for a variety of 3rd-party network control applications.
Routers packet processing software and hardware are highly complex and often have bugs
that lead to complex failure
modes that are hard to discover or diagnose. To address this problem, I am developing an
approach called network self verification
to pin-point packet processing misbehaviors at a target router. This approach has two aspects.
First, the network
control software (e.g., routing protocols) is extended to allow a verifier to obtain the
necessary information to independently
compute the control state (e.g., forwarding table) of the target router; I have found that this
is easy to achieve for both OSPF
and BGP. Second, the physical neighbor routers of the target are extended to monitor the
packet input-output behavior of
the target; I have designed coordinated packet sampling algorithms suitable for this purpose.
The verifier then checks the
observed input-output behavior against its own control state to pin-point router misbehaviors.
The simplicity of the verifier
allows it to be highly reliable: it only implements a small subset of the features of a router, it
can employ straight-forward
algorithms since it need not run at line speed, it only implements the algorithms for
computing control state (e.g. Dijkstra's
shortest-path algorithm) and does not need to implement full control protocols (e.g. OSPF).
The challenge of this approach
lies in scalably verifying a network of routers. I am developing a verifier that can verify a
cloud of routers as a unit and
algorithms that pin-point a mis-behaving router inside a router cloud.
My work is already having impact on the industry. Google has recently implemented GNP in
their content distribution
network, and a widely used BitTorrent client has incorporated its own variant of network
coordinates. The direct network
control approach is beginning to be adopted by network equipment vendors. I believe my
work will continue to address
fundamental problems and lead to important contributions in the future.
