Abstract:
In order to reduce unwanted traffic and make efficient use of limited
access link capacity or other network resources, it is advantageous
to filter traffic upstream of the end-networks that the packets are
destined to. This document describes filtering within access
Internet Service Provider (ISP) networks. The ISP's end-network
customers are given control over ISP filtering of traffic destined to
their own prefixes, since each customer's definition of desirable
versus undesirable traffic may change over time (e.g. as new network
services and protocols are introduced). In this document, we
describe an SDN-based means for customers to express flow definitions
to their ISPs in order to distinguish between desirable and
undesirable inbound traffic. These rules can be dynamically and
securely updated within the running ISP network, with full automation
One use case for this capability is in mitigating denial of service
attacks. Even if such filtering is only implemented in an ISP's
access network, it preserves capacity on the customer access links
for desirable traffic. If implemented at the ISP's edge connections
to other providers, or prior to ingress to their core, it can also
preserve the ISP's own network capacity and other resources that may
be threatened by attacks.
