    Description of Working Group:

    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.
