QoS of five types defined in the WiMAX protocol:

UGS, ertPS, rtPS, nrtPS, BE

User access control

When the user enters

the network, the system

bandwidth resource is

checked to ensure thecommitted rate.

Otherwise, the access

request is rejected (the

BE service is not

controlled).

CAR

Speed-

limited

processing

based onflow levels

Traffic shaping

Smoothening

the burst traffic

to avoid the

transient trafficimpact

Priority guarantee

Ensuring that the

service with high priority

can use the resource of

service with low priority.For example, configure

the service of UGS,

ertPS, and rtPS can use

the resource of nrtPS,

BE

Bandwidth threshold alarm

When the occupied

bandwidth resource

of the whole system

reaches thethreshold, the alarm

is available.

Hardware Platform of the WASN9770 Subrack

The hardware platform of the WASN9770 is

based on that of the Huaweis core router-

Universal Switching Router (USR) of the 5th

generation.

The signaling plane and data plane are

separately structured. In other words, the

signaling plane consist of multiple CPUs of high

performance, and the data plane consists of

multiple network processors (NPs) of high

performance and high forwarding capability.

The key boards support the hot swappable

and hot backup to ensure the reliability.

Two -48V DC power modules supply the

power in load-sharing mode.

WASN9770 Subrack

Based on the NE40-8 subrack, the width is 19 inches and the height

is 18 U. The fan frame in 5+1 backup mode, cabling trough, air

intake vent are available.

Up to 10 slots are available. The boards are as follows:

1SRU (Switching and Routing Unit ): It is used to collect the route

information and generate the route list. In addition, it is the

operation and maintenance agent and the data packet switching

center.2SPU ( Service Processing Unit): It is used to process the service

related to the WiMAX protocol.

3LPU (Line interface Processing unit): It is used to provide the

physical interfaces to external networks and data forwarding

function.

All boards are configured in 1+1 backup mode.

Two SRUs are fixed in slots 9 and 10. Other slots are used for the SPU and LPU.

Generally, two LPUs are configured. Slots 1 and 2 are reserved for the LPU to facilitate cabling.

Two/four/six SPUs are configured according to the requirements. The neighboring two boards are one

pair and can be configured in slots 3/4, slots 5/6 and slots 7/8.

The RS-232 signal level and RJ-45 are used to

connect the LMT.

AUX interface

The RS-232 signal level and RJ-45 are used to

monitor the power distribution frame.

SPU: Introduction

SPU: It is used to complete

all the service processing

functions of the WASN9770.

The functions are as follows:

Protocol processing at theR6/R4/R3 interface

Accounting flow statistic

Encapsulation and

forwarding of the service

packet

LPU: Introduction

LPU: It provides the physical

interfaces to the external

networks. The types of

interfaces are FE, GE, and

POS. The LPU searches for

the route table and forwards

the datagram. The LPU can

works in active and standby

mode or load-sharing hotbackup mode.

flow

Service data flow: After

receiving the UL or DL data, the

LPU directly processes and

forwards it if the data is common

route packet. The LPU forwards

the data to the SPU if the data

must be processed by the SPU.

After being processed by the SPU,

the data is forwarded through the

LPU.

Signaling flow: The LPU

receives the UDP signaling or

DHCP signaling from the R6

interface. If the destination

address is the IP address of the

R6 interface on the SPU, the LPUforwards the signaling to the

related SPU. After processing the

signaling, the SPU forwards the

corresponding signaling to the

LPU through the SRU.
