BGP Flowspec Interoperability Lab

This presentation will summarize the results and findings of a joint research project (next layer and T-Mobile) on BGP flow specification interoperability in inter AS deployments carried out last summer.

BGP flow specification (RFC 5575) defines a protocol to rapidly deploy access control lists and forwarding policies (flow-specification filters and actions) amongst all participating routers via a newly defined BGP address family. This technology is increasingly deployed within provider networks for DDoS mitigation.

Since BGP is used to exchange the flow specification filters, this technology also allows to exchange filters with adjacent networks (external BGP). However, inter AS deployments are very rare. To encourage the ISP community to extend their BGP flow specification deployment to their peers and customers, we built a router lab with equipment of four different manufacturers (Alcatel/Nokia, Cisco, Huawei, Juniper) to demonstrate how such a multi vendor inter AS deployment could look like. We share our complete lab setup and findings with the ISP community.

CEE Peering Days is an international conference of experts directed at network engineers, peering coordinators, internet providers, cloud administrators and data centre operators in the Central and Eastern European Region.

Since 2013 the conference regularly attracts around 200 participants and has been continuously supported by sponsors from the Telecommunication and IT community from across Europe.

The programme combines technical workshops with professional presentations and offers plenty of time and space for social networking and bilateral talks.

The conference in 2017 is planned as a two-day event at the Austria Trend Hotel Ljubljana and will include a social evening in the centre of Ljubljana on 22nd March.

The conference will be hosted by NIX.CZ, NIX.SK, and
