GB/T 26244-2010Information technology -- Group management protocol (English PDF)

Foreword

This standard is based on GB/T 20000.2-2001 identical with ISO/IEC 16513:2005 "Information technology - Group Management Protocol." this standard by the National Information Technology Standardization Technical Committee and centralized.

This standard was drafted. China Electronics Standardization Institute, Beijing Sound Xun Electronics Co., Ltd.

Introduction

Traditional multicast transport protocol does not include the Group Management (in accordance with the recipient's join and leave) and dynamic mechanism to modify membership information.

GMP multicast session management (SM) mechanism and Membership Management (MM) provides a framework that supports multicast session and Members of the management requirements. This protocol can be used as solutions reliability of multicast communication.

GMP will operate on the traditional transport protocol and/or ECTP, as shown in FIG.

IT Group Management Protocol

1 Scope

This standard specifies the Specification Group Management Protocol (GMP), the agreement is to create a group session, and should be involved in the management of the group members Application layer control protocol.

GMP by the session management (SM), Membership Management (MM) and information exchange function between the composition of the SM and MM. SM Responsible for session creation and deletion. MM-based membership management retrieved from the SM to the session information list.

In accordance with ITU-T Recommendation .X.601 "Multi-peer communications framework" multi-peer communications services in seven different stages. registration, Registration, activation, data transmission, deactivation, cancellation of registration and deregistration. Since one of these operations --- --- allows data transfer ECTP or TCP to perform, and therefore the remaining SM can perform. Create, notification, registration,, activation, including session pass Advertisement. In addition, members of the MM management activities registered or groups within groups.

SM can provide convenient user interface, because it can be implemented on the Web. MM operation of the transport protocol user it is transparent.
