Internet-Draft       The VLAN Model for Applications          March 2009


Abstract

   This document describes the model for application and network
   interaction in reaction to Application Area Architecture Workshop
   held on February 11 and 12, 2008.  There is not completed mechanism
   for collaboration between application and network yet even though a
   solution is required.  The model proposed in this document is
   designed without a layer violation.  This document propose the VLAN
   model for the application users.

1.  Introduction

   This document describes the model for application and network
   interaction in reaction to Application Area Architecture Workshop
   held on February 11 and 12, 2008.  There is not completed mechanism
   for collaboration between application and network yet even though a
   solution is required.  The model proposed in this document is
   designed without a layer violation.  This document propose the VLAn
   model for the application users.

1.1.  Requirements notation

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].

2.  VLAN Model

   The VLAN is one of technologies to implement the L2 layer closed
   network.  Since VLAN configuration is proprietary parameter and
   interface, it is useful to provide common model and schema for the
   application users.

   This model is the primitive data model involved by usage scenario
   corresponding to requirements.  This kind of primitive data model is
   required to standardized because it should be common for application
   and user.  Application and user don't need to CLI level configuration
   using this model.

   We designed the common VLAN model as below.

2.1.  VLAN Schema

   This section describes the VLAN Schema.  This schema can describe
   both tagged vlan and untagged vlan.  Tagged vlan id is managed to
   keep uniq and not exceed to 4096.
