Summary: | Network Protocols (ICNP), 2017 IEEE 25th International Conference
on, 1-2 The current Internet routing ecosystem is neither sustainable nor economical.
More than 711K IPv4 routes and more than 41K IPv6 routes exist in current
global Forwarding Information Base (FIBs) with growth rates increasing. This
rapid growth has serious consequences, such as creating the need for costly FIB
memory upgrades and increased potential for Internet service outages. And while
FIB memories are power-hungry and prohibitively expensive, more than 70\% of
the routes in FIBs carry no traffic for long time periods, a wasteful use of
these expensive resources. Taking advantage of the emerging concept of
programmable data plane, we design a programmable FIB caching architecture to
address the existing concerns. Our preliminary evaluation results show that the
architecture can significantly mitigate the global routing scalability and poor
FIB utilization issues. |
