weil wir beim letzten Meeting kurz das Thema remote traffic blocking zwecks
DDOS-Mitigation angesprochen haben: Es ist eine IETF-WG zu dem Thema
vorgeschlagen worden:

> The aim of DDoS Open Threat Signaling (DOTS) is to develop a standards
> based approach for the realtime signaling of DDoS related telemetry and
> threat handling requests and data between elements concerned with DDoS
> attack detection, classification, traceback, and mitigation.
> The elements may be described as:
> * On-premise DDoS mitigation platforms
> * Service provider DDoS mitigation platforms
> * Other network elements and services with the ability to analyze and/or
> influence network traffic
> Elements may participate in DDoS detection, classification, traceback
> and mitigation individually or within the context of a larger
> collaborative system.
> These elements may be communicating inter-domain or intra-domain over
> links that may be congested by attack traffic resulting in potentially
> hostile conditions for any type of upstream signaling, in particular
> transport protocols that yield to congestion, and more generalized
> signaling and  telemetry solutions.  Robustness under these conditions
> is paramount  while ensuring appropriate regard for authentication,
> authorization,  privacy and data integrity.  Elements may be deployed as
> part of a wider strategy incorporating multiple points of DDoS
> detection, classification, traceback and mitigation, both on premise or
> service provider based.  Should changing conditions necessitate altering
> the specifics of mitigation actions and/or the topological scope of
> mitigation coverage, timely and  effective signaling of telemetry and
> current threat status to all elements involved in the mitigation is
> essential.  Feedback between participating elements is required for
> increased awareness supporting effective decision making.
> The WG will, where appropriate, reuse or extend existing standard
> protocols and mechanisms (for example, IPFIX and its associated
> templating and extension mechanisms).  Any modification of or extension
> to existing protocols must be in close coordination with the working
> groups responsible for the protocol being modified, and may be done in
> this working group after agreement with all the relevant WGs and
> responsible Area Directors.  The WG may coordinate on a situationally
> appropriate basis with other working groups and initiatives which
> compliment the DOTS effort e.g. M3AAWG, SACM, MILE, SUPA, I2NSF et. al.
> The WG will document requirements for the transport protocol to be used
> for the signaling of DOTS and consult with the Transport Area about the
> requirements and, if applicable, any new development of a encapsulation
> scheme for DOTS.
> The charter of the working group is to produce one or more standards
> track specifications to provide for this open signaling in the DDoS
> problem space.  While the resulting standards should be designed so they
> apply to network security applications beyond the DDoS problem space,
> this working group will focus on signaling and coordination mechanisms
> directly related to DDoS attack detection, classification, traceback and
> mitigation, incorporating the general principles articulated in RFC5218
> https://tools.ietf.org/html/rfc5218.  Focusing the WG efforts on DDoS
> is intended to meet the community's desire for a deployable solution in
> the near term.  The specification(s) produced by the WG will include a
> standard mechanism for authentication and authorization, data integrity,
> and providing for privacy in operation, with privacy-friendly choices
> being the default in all cases.
> The WG will produce the following deliverables and milestones:
> * Document or Documents describing the problem space, use cases,
> protocol requirements and other qualifying information as the WG sees
> fit.
> * Document or Documents specifying protocols and associated data models
> to address the stated goals of the WG.
> Milestones:
>  Feb 2016 - Requirements/use case information document to IESG
>  May 2016 - Transport document as proposed standard to IESG
>  Jun 2016 - Data model document as proposed standard to IESG
