EDA 1200 System Overview

2.1.2 Access Network

The EDA 1200 access network provides the means to provide the services to

the End-users. The EDA 1200 access network is composed of specialized

nodes (telecom grade), with built in mechanisms to ensure network and

End-user security, and Quality of Service (QoS). The main principle of the EDA

1200 access network is illustrated in Figure 5 on page 8.

Figure 5 EDA 1200 Access Example

The access network is based on Ethernet and IP. The End-users are connected

to an Access Node providing different drop technologies. The Access Node

controls the services given to the End-users, and traffic to and from the

End-users. An example with four services: one Voice and two data services

provided from outside the network, and one video service provided from within

(not through a router) is depicted in Figure 5 on page 8.

The Access Node has security mechanisms that protect the network from

malicious attacks, and other mechanisms that protect the End-users.

In order to provide QoS, the Access Node has mechanisms to ensure

prioritizing and minimize delay of traffic. In both cases (security and QoS), the

Access Node controls the downlink traffic to the End-user, and the uplink traffic

to the network. Downlink traffic from the gateways and service servers to the

Access Nodes is controlled by the gateways and servers.

EDA 1200 access network using different drop technologies and different

network elements is depicted in Figure 6 on page 9 .
