    YANG Model for Transmission Control Protocol (TCP) Configuration
                     draft-scharf-tcpm-yang-tcp-04

Abstract

   This document specifies a YANG model for TCP on devices that are
   configured by network management protocols.  The YANG model defines a
   container for all TCP connections and groupings of fundamental
   parameters that can be imported and used in many TCP implementations.
   The model includes definitions from YANG Groupings for TCP Client and
   TCP Servers (I-D.ietf-netconf-tcp-client-server).  The model is NMDA
   (RFC 8342) compliant.

1.  Introduction

   The Transmission Control Protocol (TCP) [RFC0793] is used by many
   applications in the Internet, including control and management
   protocols.  Therefore, TCP is implemented on network elements that
   can be configured via network management protocols such as NETCONF
   [RFC6241] or RESTCONF [RFC8040].  This document specifies a YANG
   [RFC7950] 1.1 model for configuring TCP on network elements that
   support YANG data models, and is Network Management Datastore
   Architecture (NMDA) [RFC8342] compliant.  This module defines a
   container for TCP connection, and includes definitions from YANG
   Groupings for TCP Clients and TCP Servers
   [I-D.ietf-netconf-tcp-client-server].  The model focuses on
   fundamental and standard TCP functions that are widely implemented.
   The model can be augmented to address more advanced or
   implementation-specific TCP features.

   Many protocol stacks on Internet hosts use other methods to configure
   TCP, such as operating system configuration or policies.  Many TCP/IP
   stacks cannot be configured by network management protocols such as
