1TP-Assist SolutionAbout This Chapter

Transport packet assist (TP-Assist) allows a packet network to be efficiently planned, quickly

deployed, and easily maintained like an SDH network.

1.1 Background

With the explosive growth of data traffic, services carried on MANs and mobile bearer networks

have changedfrom traditional voice services to data services (mainly, video, Internet, and VoIP

services). MANs and mobile bearer networks, themselves, have also evolved from mainly SDH

networks to mainly packet networks. However, compared with SDH technologies, packet

transport technologies have many disadvantages in performance monitoring and fault diagnosis,bringing huge O&M challenges to packet networks (especially large-scaled packet networks).

1.2 TP-AssistO&M System and Functions

In compliance with the network-centered, service-centered, and intelligent packet network O&M

trend, Huawei promotes a brand new O&M system based on the TP-Assist solution. The O&M

system covers the entire O&M process from network planning to fault diagnosis.

1.1 Background

With the explosive growth of data traffic, services carried on MANs and mobile bearer networks

have changed from traditional voice services to data services (mainly, video, Internet, and VoIP

services). MANs and mobile bearer networks, themselves, have also evolved from mainly SDH

networks to mainly packet networks. However, compared with SDH technologies, packet

transport technologies have many disadvantages in performance monitoring and fault diagnosis,

bringing huge O&M challenges to packet networks (especially large-scaled packet networks).

The O&M challenges include:

l How to quickly plan and deploy large-scale packet services

Packet services are much more complex than SDH services. Especially, packet networks

have various networking modes, with each using different transport technologies and

different packet forwarding modes. This requires that O&M personnel be highly skilledand exercise caution during configuration. In addition, it is more complex to verify packet

services than to verify SDH services, which makes it more difficult to deploy and

commission packet services.

l How to monitor packet service performance

Unlike SDH services wherein containers at each level have dedicated overhead bytes for

performance monitoring, packet services have no corresponding overheads. How to

implement delicacy monitoring over each service and each service level is a huge challenge.

l How to quickly locate a fault

Packet networks and services on the packet networks are more complex than SDH networks

and services on the SDH networks. In addition, fault isolation performance on packet

networks is poorer than on SDH networks. For example, once a broadcast storm occurs on

a packet network, the entire broadcast domain will be affected. Therefore, O&M personnel

must be capable of quickly locating and rectify the fault.

To handle these difficulties and challenges, the packet network O&M measures must evolve in

a network-centered, service-centered, and intelligent manner.

Table 1-1Packet network O&M trend

O&M Trend Main Requirements

Network-centered Conduct service configuration, monitoring,

and fault diagnosis at the network level,

instead of on a per-NE basis.

Service-centered Quickly deploy and commission services.

Clearly display service paths and views.

Conduct monitoring by service, allowing the

impacts that each feature has on services to

be displayed in a real-time manner.
