By: packetlight Traditionally, telecommunication providers offered its subscribers voice services through copper based networks. However, these voice networks have evolved into complex networks capable of providing subscribers integrated triple play access to transport voice, video and large capacities of data at incredible speeds. These networks are comprised of variety of network elements and variety of technologies, the management of which would be near impossible without a centralized management system. Element Management Systems (EMS) have proven to be a necessary tool in managing this infrastructure, providing a central platform for configuring and controlling multiple network elements. EMS's manages one or more specific types of network elements in a telecommunications network and provides crucial tools to the service providers for satisfying customer needs for the fast deployment of services as well as meeting high Quality of Service standards (QoS). Generally, one EMS is implemented and used for managing a group of elements and providing high level of controllability for the network managers. This White paper explains how PacketLight’ What is RADView RADview-EMS solution is proprietary software developed by RAD Data Communications to support all RAD integrated network elements. It is a PC-based, modular, client-server, scalable management system, capable of support at least 200 network elements and several client operation at the same time. It provides secure configuration and fault management capabilities in a access based database. RADview-EMS has southbound SNMP interface to the network elements. RADview-EMS enables the distribution of client and server functions to separate computers. Management functions provided by RADview-EMS are divided into four different categories, which comply with the FCAPS model (excluding the Accounting element): Fault – alarm and trap handling, polling service Configuration (provisioning) Performance – provided by the intuitive PL Web application Security – controls NE access, enables NE functions and accesses logs The fault history is gathered through incoming traps from the SNMP agent and is logged into a commercial Informix® or Oracle® databases. The information in the databases are accessible by clients through Event Browser tool which allows filtering of alarms, alarm correlations, exporting of trap files, and other functionality. The access to the database is based upon user authentication, and the definition of user profiles is supported by the EMS Admin Console. Furthermore, the EMS Network Manager application allows administrators to view a map of the network elements and see the dynamic status of the nodes. Also, the complete inventory of the network can be viewed via the Net Inventory application. It further provides tools for simple maintenance of the network elements via software and configuration upload and download support through RAD TFTP application. How does PacketLight integrate? PacketLight products integrate into the RADView EMS system to allow administrator viewing of the fault history, inventory, configuration, performance data, Software download and configuration upload and download to the network elements. Faults: The fault trap information of the PacketLight boxes is captured through SNMP traps by the EMS and displayed in the Event Browser. From here, the data can be sorted according to the specific product, Faults, and all other criteria available in the viewer. Additionally, each alarm can be isolated and managed individually as demonstrated in Figure 1.0. Configuration: Through PL web application (Figure 2.0), administrators can configure each system with proper name and customer name as well as setup each optical port separately for appropriate services. Additionally, protection can be established on the ports and OSC channels can be configured. Here also can be setup SNMP traps for all supported SNMP versions. Performance: Security: PacketLight Products are fully integrated with RADView EMS security features. EMS provides full controls of NE (Network Elelment) access, enables NE functions and is capable of viewing access logs. Therefore, EMS eliminates the need of multiple security role setups on multiple network elements. Inventory: Administrators are able to receive a full picture of all network elements through inventory management application. Here, information such as: NE components, version of hardware, software and of firmware, and a serial number of NE is presented in a hierarchical mode. This information can further be filtered and manipulated for reporting purposes according to the needs of the administrator. Figure 3.0 shows a short extract of the Inventory Table. Conclusion The RADView-EMS plays a crucial role in the total network management solution. It is exposed to all telecommunication network elements and serves as a central control post for all NE’s of a specific type. It is a sole mediator of all incoming information of performance and faults data, and is the storage point of all such history. Since, the EMS is closely matched with a specific network element type, it is very important that each of these elements are EMS ready. PacketLight Networks integrates with RADView-EMS to allow administrators seamless integration of PacketLight products within their telecommunication networks, enabling them to utilize fully the functionality, control and maintenance of the NE’s via a centralized EMS system. The integration of PacketLight under RADView-EMS also enables any customer using RAD data communication’ About PacketLight WDM products PacketLight Networks has been manufacturing high-end data transport equipment for over seven years and has vast experience in dealing with customers that require secure, reliable and protected solutions to transport data over CWDM, DWDM and Dark fiber.
