4.1.3 Typical OCS Networking
Networking for Multi-Granularity Service Grooming, Service Convergence and
Bandwidth Switching
The OptiX OSN 8800 can provide the networking application of the multi-granularity service
grooming and service convergence functions.
Figure 4-7 shows the networking application of the multi-granularity service grooming and
service convergence functions of the OptiX OSN 8800. The OptiX OSN 8800 implement the
large-capacity grooming of STM-64, STM-16, STM-4, STM-1 services. The OptiX OSN
OptiX OSN 8800 can form a hybrid network with different equipment such as DWDM and
MSTP.

Networking Application of Ethernet Services
The networking application of Ethernet services includes point-to-point networking for the
GE/10GE service, Layer 2 switching networking for the GE/10GE service, and transparent
transmission networking for the GE service.
67
Point-to-Point Networking for the GE/10GE Service
A large and flexible bandwidth is required by Internet service provider (ISP) and application
service provider (ASP) for efficient service connection. The OptiX OSN 8800 provides a
direct GE service interface. Therefore, the point-to-point transmission of the Ethernet services
over a long distance can be realized over the SDH networks.
Figure 4-8 shows the flexible networking modes of the OptiX OSN 8800. The network can be
a chain, a ring, a mesh network or a combination of these three modes.

Layer 2 Switching Networking for the GE/10GE Service
The OptiX OSN 8800 equipment provides the Layer 2 switching boards to achieve the Layer
2 switching from a GE/10GE service to a GE/10GE service.

Networking with SDH Equipment to Be the Metropolitan Backbone Node
The OptiX OSN 8800 node features powerful service grooming capability and stronger
survivability. The abundant service interfaces of the OptiX OSN 8800 meet the demand for
grooming services in the metropolitan backbone network. It can simplify the networking
topology and can be deployed in a hybrid network together with the other OptiX OSN product.
Working with the end-to-end trail management function of the U2000, the OptiX OSN 8800
can be operated and maintained in simpler and more convenient manner.

About the ASON
About This Chapter
The ASON, the automatically switched optical network, is a new generation of the optical
transmission network, all called ASON optical network. This section describes some basic
concepts of the ASON and application of the ASON software.
5.1 Overview
The ASON software provided by Huawei can be applied to the OptiX OSN series products to
support the evolution from traditional network to ASON network. It complies with the ITU
and IETF ASON/GMPLS-related standards.
5.1 Overview
The ASON software provided by Huawei can be applied to the OptiX OSN series products to
support the evolution from traditional network to ASON network. It complies with the ITU
and IETF ASON/GMPLS-related standards.
5.1.1 Background and Advantages
Compared with the WDM network, the transmission network that applies the new ASON
technology shows advantages in service configuration, bandwidth utilization and protection
schemes.
In the traditional transmission network, the WDM transmission equipment functions as fibers.
Currently, the WDM transmission equipment also carries services. As a result, more
requirements are for the operability of the WDM equipment. The traditional network has the
following problems:
The service configuration is complex and capacity expansion or service provision takes a
long period.
The bandwidth utilization is of a low rate and low efficiency. In a ring network, half of
the bandwidth should be reserved.
Just a few protection schemes are available and the performance of self-healing
protection is poor.
The ASON has been developed to solve these problems. This technology involves signaling
switching and a control plane to enhance its network connection management and recovery
72
capability. It supports end-to-end service configuration and the service level agreement
(SLA).
Service Configuration
Traditional WDM networks are generally chains and rings. The trails and timeslots of their
services are manually configured ring by ring and point by point, which consumes a lot of
time and effort. As networks become increasingly large and complicated, this service
configuration mode cannot meet the rapidly increasing user demands.
The ASON successfully solves this problem by end-to-end service configuration. To configure
a service, you only need to specify its source node, sink node, bandwidth requirement and
protection type; the network automatically performs the required operations.
Bandwidth Utilization
Traditional WDM optical transmission networks have a large amount of resources reserved
and lack advanced service protection, and the restore and routing functions. In contrast, with
the routing function the ASON can provide protection by reserving fewer resources, thus
increasing network resource utilization.
Protection and Restoration
Chain and ring are the main topologies used in a traditional WDM network. Optical line
protection or board-level protection are the main protection schemes for the services. In
ASON, mesh is the main topology. Besides protections, the dynamic restoring function is
available to restore the services dynamically. In addition, when there are multiple failures in a
network, the services can be restored as many as possible.
According to the difference in the service restoration time, multiple service types are defined
in ASON networks to meet different customer requirements.
5.1.2 Features of the ASON
As a new technology on the transmission network, the ASON has its own features.
Compared with the traditional network, the ASON has the following features:
Supports the route calculation strategy that is based on optics parameters and eliminates
the route that does not comply with optics parameters automatically.
Supports the automatic adjustment of wavelengths during rerouting or optimization,
which solves the wavelength conflict problem. (For OTN network)
Wavelengths can be automatically allocated for newly created services.
Configures end-to-end services automatically.
Discovers the topology automatically.
Provides mesh networking that enhances the survivability of the network.
Supports different services which are provided with different levels of protection.
Provides traffic engineering and dynamically adjusts the network logic topology in real
time to optimize the configuration of network resources.
