TIA TSB-87-2016

Description / Abstract: Introduction

The Multicast Perspectives is a high level view of the processes involved in rendering CDPD and IP Multicast services. The CDPD Multicast service features include the following:

a. Multiple M-ESs get a copy of the message, regardless of the number of M-ESs or their location

b. More efficient use of the network; therefore, it should be less work for applications

c. Unacknowledged; no confirmation of reception by intended receivers

d. Data is not encrypted by the network

e. Multicast registrations are authenticated on a per-Multicast group member basis; each Multicast group member has its own authentication credentials for a Multicast NEI

f. Application must use UDP-style transport service: TCP-style transport service is not valid for Multicast.
