as one of the biggest challenges facing the Internet today.
Point solutions for individual problems further increase system
complexity while not addressing the underlying causes.
In this paper, we argue that many network-management
problems stem from the same root cause—the need to maintain
consistency between the physical and logical configuration
of the routers. Hence, we propose VROOM (Virtual
ROuters On the Move), a new network-management primitive
that avoids unnecessary changes to the logical topology
by allowing (virtual) routers to freely move from one physical
node to another. In addition to simplifying existing
network-management tasks like planned maintenance and
service deployment, VROOM can also help tackle emerging
challenges such as reducing energy consumption. We present
the design, implementation, and evaluation of novel migration
techniques for virtual routers with either hardware or
software data planes. Our evaluation shows that VROOM
is transparent to routing protocols and results in no performance
impact on the data traffic when a hardware-based
data plane is used. | type: | misc |
