TRADITIONAL NETWORK INFRASTRUCTURE

COMPONENTS

Switching Network Switching nodes is the intermediate points on the telecommunications

network, which made a temporary connection between the input (the

subscription server) and the output (subscriber) as required. The network

provides mobile phone services and the non-fixed-switching nodes are

used including: the switching node region (the satellite operator), theswitching node local, local (Host) and the national relay switching node

(Tandem).



38/61

SWITCHING NETWORK

Type of the Switches: Circuit-switched network: Switching process is divided into 3 phases, set

up, communication and liberation (release). To set the connection controls,

and Liberation, the network switches to channel using signaling

techniques for implementation (common channel signaling R2 signaling,

the private channel CC7). Packet switching: Divide the data traffic into packets and transmitted on a

network share, the period set, transmitter and frees are made at the same

time over a period of time and are often determined by the packet header.

Advanced Switching IP/ATM.

The transmission network is the largest information

transmission network of the telecommunications network.

Transmission network connection function, transmission of

information between the nodes in the switching region, the

regions, the national relay switching node, the total of

international radio stations, and between nationaltelecommunications networks with international networks. The

transmission network is split into two levels: the backbone

transmission Network (the province) and local transmission

network (in the Cabinet).

TRANSMISSION NETWORK



42/61

Backbone transmission Network functions to connect localswitching node (Host) with national switching node (Tandem),

international switching nodes (Gateway) and the international

network. The network was previously mainly used

transmission using optical cable and Microwave link. Today,

due to the development of technology should primarily use

high-speed optical cable.

as follows: Transmission and access

layer (Access + Transport)

Media layer;

Control Layer

Management Layer

NGN structure



53/61

Transmission Parts Physical layer: optical transmission with optical wavelength

Multiplexing technique of DWDM is used.

layer 2 and layer 3:

Transmission across the network core (core network) based on technical

packages for all these services with quality of service QoS optionsrequired for each type of service.

ATM or IP/MPLS may be used as the background for transmission

across the network core to ensure QoS.

The core may belong to MAN or backbone

The routers used in the core network as large flow, on the contrary, whenlow traffic, switch-router can assume the function of this router always.

TRANSMISSION PARTS



54/61

The access layer: Physical layer:

Cable line: coaxial cable, xDSL currently in use. However in DWDM

optical transmission future, PON (Passive Optical Network) will

gradually dominate and market xDSL, cable modem is gradually

shrinking. Mobile communication: GSM or CDMA technology, fixed wireless

access, satellite.

Layer 2 and Layer 3: IP technology will make the background for

network access.

THE ACCESS LAYER



55/61

As part of the: The device in the media layer is thecommunications port (MG-Media Gateway) includes:

The portal access: AG (Access Gateway) connections between the core

network with network access, RG (Residential gateways) core network

connections with the network of subscribers at home.

Communication ports: TG (Trunking Gateway) to connect with the coreadvice based PSTN/ISDN, WG (Wireless Gateway) connected to the

core network to the mobile network.

COMMUNICATIONS LAYER
