WAN-Wide Area Network

A WAN (Wide Area Network) is a computer network that covers a broad geographical area (eg.

Internet) that is used to connect LAN and other types of network systems. There are the items

within the WAN section:

WAN Interface

and

WAN Service

.

WAN Interface

ATM

Layer2 Interface:

2 transfer mode, ATM or PTM.

The following is the interface listing table.

Click

Add

to add WAN interface.

VCI/VPI:

enter the VCI/VPI from your ISP.

Link Type:

select the link type (protocol), EOA, PPPoA, IPoA.

Connection Mode:

L

Default Mode:

this mode only allows single service over one connection.

L

VLAN MUX Mode:

this mode allows multiple services over one PVC.

The two modes can be different in WAN service configuration. And PPPoA and IPoA do not use

Ethernet frames for data transfer so they cannot work with VLAN Mux feature. Thus,

Connection

45

Mode

Parameter will be hided if you select PPPoA or IPoA in Link Type.

Encapsulation Mode:

select the encapsulation mode from the drop-down menu according to the

link Type.

Service Category:

select the service category from the drop-down menu to determine your service

category.

L

UBR without PCR: UBR(Unspecified Bit Rate), PCR(Peak cell Rate)

UBR is a kind of QoS, which doesn’t provide assurance about the cell latency, the bit loss rate etc,

it is a best-effort service.

IP QoS Schedule Algorithm:

select the Schedule Algorithm, SP(Strict Priority), always sends the

packets with the highest priority, WFQ(Weighted Fair Queuing), an automatically bandwidth

adjusting method, sharing the available bandwidth when congestion happens, the bandwidth is

assigned according to the priority and the weight value. Turn to the

Quality of Service

>

Queue

Config

section for more information.

Precedence of the default queue:

default 8(lowest)

Weight Value of default queue:

enter the value, 1-63, the highest is 63.

MPAAL Group Precedence:

select the precedence identification, 1-8, the highest is 1.

L

UBR with PCR/ CBR(Constant Bit Rate)

UBR is a kind of service providing constant rate service, is idea for timely and fixed bandwidth

needed service.

Peak Cell Rate:

enter Peak Cell Rate.

46

L

None Realtime VBR/ Realtime VBR(Variable Bit Rate)

VBR is a kind of service providing some assurance about latency and bit loss rate and is often

associated with video and time sensitive service. NR-VBR allows more time delay to R-VBR.

Enter Peak Cell Rate, Sustainable Cell Rate and Maximum Burst Rate.

Click

Apply

to apply the WAN interface.

Check the remove checkbox, then press

Remove

to delete it only if this interface are not used by a

WAN Service, if it is used by a WAN service, first remove the WAN service, then turn back to remove

the interface.

Don’t feel confused, it will remind you by the following prompt window.

47

PTM

PTM Setting is similar to ATM.

PTM Priority:

Select the PTM priority, Normal or High.

Click

Apply

to save your settings. The interface will be added to the PTM Interface listing table.
