Charter charter-ietf-grow-03

The Border Gateway Protocol (BGP) is fundamental to the operation
  of the Internet. In recent years, occurrences of BGP related
  operational issues have increased, and while overall
  understanding of the default-free routing system has improved,
  there is still a long and growing list of concerns. Among these
  are routing table growth rates, interaction of interior and
  exterior routing protocols, dynamic properties of the routing
  system, and the effects of routing policy on both the size and
  dynamic nature of the routing table. In addition, new and
  innovative uses of BGP, such as the use of BGP as a signaling
  protocol for some types of Virtual Private Networks, have created
  new and unexpected operational issues.
  
  The purpose of the GROW is to consider the operational problems
  associated with the IPv4 and IPv6 global routing systems,
  including but not limited to routing table growth, the effects of
  the interactions between interior and exterior routing protocols,
  and the effect of address allocation policies and practices on
  the global routing system. Finally, where appropriate, the GROW
  documents the operational aspects of measurement, policy,
  security, and VPN infrastructures.
  
  GROW will also advise various working groups, including the IDR
  and RPSEC working groups, with respect to whether it is
  addressing the relevant operational needs, and where appropriate,
  suggest course corrections. Finally, operational requirements
  developed in GROW can also be used by any new working group
  charged with standardizing a next generation inter-domain routing
  protocol.
  
  GOALS:
  -----
  
  (i). Evaluate and develop various methodologies of controlling
                  policy information in order to reduce the effect of
                  prefix sub-aggregates beyond the necessary diameter, so
                  as to reduce the Network Layer Reachability Information
                  (or NLRI; see e.g.,draft-ietf-idr-bgp4-23.txt) load on
                  network infrastructure.
  
  (ii). Document and suggest operational solutions to problematic
                  aspects of the currently deployed routing
                  system. Examples include instability caused by
                  oscillation of MULTI_EXIT_DISC (or MED; see RFC 3345)
                  values.
  
  (iii). Analyze aspects of supporting new applications, including
                  extending existing routing protocols and creating new
                  ones. This includes risk, interference and application
                  fit.
  
  (iv). Determine the effect of IGP extensions on the stability of
                  the Internet routing system.
  
  (v). Document the operational aspects of securing the Internet
                  routing system, and provide recommendations to 
  other     
                  WGs.
