Introduction to PNMSj

System Overview

The NEC PNMS is a sophisticated supervisory tool for transmission equipment and allows operator to perform remote system monitor alarms, control NE configuration parameters and display event logging and performance data in either UNIX or Microsoft Windows platform. Fig. above shows a typical PNMS application. The system consists of a central computer (PNMS PC) and a number of remote data processing nodes called as PM cards. It supervises and controls the Pasolink transmission equipments.

System ComponentsPNMS : The central site computer is the central operator interface and database from which system operators manage the Pasolink network. It receives the data via PM card, stores it and displays it to the operator in a variety of formats. It accepts command request from the operators and sends them to the onsite equipment for execution. Two types of PNMS can be proposed in accordance with customers network size viz : PNMS on Windows NT/2000/XP and the other is PNMS on UNIX OS.

Pasolink Management (PM) Card : PM cards are located at each site in the monitored network to collect alarm and status information from Pasolink and to control that equipment in response to commands from the central site operator. The PMC primary tasks are to control and acquire data from Pasolink at remote location and transfer this data back to the central site. The PM card is designed as plug-in modules.

PM card is functioned as SNMP agent, which detects alarm and status changes in monitored equipment and sends change of notifications to PNMS. PM card retains the MIB data and transmits a response to SNMP GET commands from PNMS and PNMT.

PMC Operation ModesDepending on the size, a network can normally be divided into a number of sub-networks. To distribute the traffic load we normally define one of the PMC as master and the rest as slaves through discrete design. We also call a master as Central PMC (CPM), a sub-master as SubCentral PMC (SCPM) and a slave as Remote PMC (RPM). Even though there is no difference in the hardware design, the PMC will be playing different roles according to the installed software in a NMS as follows : Master mode (CPM) :

To get information from the remote sites and to generate reports to the PNMS. The CPM may act as a terminal unit; which processes and then transfers all the physical information of equipment, which is directly connected to the CPM.The CPM is connected to PNMS via a dedicated serial communications link, and passes messages received from RPMCs to the PNMS for display.

Sub Master mode (SCPM) : Master and gateway function which performs the same activity as a CPM acting as a gateway between CPM and RPM and routing the messages from CPM to RPM and back. It also performs a terminal unit function that acts as a stand-alone data acquisition and control unit which processes and then transfers all the physical information of equipment which is directly connected to the SCPM. This function is same as that of RPM.

Slave mode (RPM) : It is a stand-alone data acquisition and control unit. It monitors and controls equipments at some remote location. The prime task of RPM is to monitor, control and transfer data back to the central site.

IP AddressFor the TCP/IP communication, each node connected in the network needs to be given an IP address. By interpreting the given IP address, all the nodes can communicate each other.The form of the IP address is : - Length : 32 bits - It consists of two parts Network Part (Also called Network Address) Field to identify the logical network

Host Part (also called Host Address)-Notation Dividing 32 bits into four 8-bits sections, changing each of them into decimal numbers, and arraying them in a line with dots separating those numbers (called dot notation)Example : 1100

Classifying IP address (Class A B and C)

IP Address

IP address are classified according to the values of their most significant 1 to 4 bits.There are five classes; A, B, C, D and E. The classes D and E are however, used for special purposes only and are not dealt with. Class A, B and C are explained here. These three classes are allocated to nodes and devices according to the number of networks and host computers in a network. Class A (from 0.x.x.x to 127.x.x.x)Number of networks : 128 (= 2^7)00 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 3 1

Global IP address and Private IP address

IP Address

The Global Address refers to the IP address uniquely assigned to a device connected to the Internet and is essential for communicating through the Internet. The Global Address is centrally administered by IANA, under whose jurisdiction the NICs (Network Information Centers) of each country allocates addresses to such organizations as service providers. The Private Address can be freely allocated within an organization without applying for the allocation to NIC. The address space which never be accessed in the Internet is defined by RFC (Request For Comment) -1918.Privet IP Address Space

Class A Class B Class C

From 10.0.0.0 to 10.255.255.255.255 From 172.16.0.0 to 172.31.255..255 From 192.168.0.0 to 192.168.255.255Address Translation at * NAT/NAPT

Subnet

IP Address

Since recent trend has accelerated the introduction of LAN, the number of segments (logical networks) in many corporations has significantly increased. However, allocating class-B or class-C addresses will swiftly exhaust the address space. To cope with this situation was created Subnet Address that allows to further subdivide a network address.A subnet address is a means to expand the number of identifiable networks by using several bits in the host part of the IP address for each class. In the subnet environment, the network address is handled as the network part plus subnet part, thus expanding the network part by partial use of the host part. When viewed from outside of the subnet, it looks like a network of the same class. Without Subnet (IP address of class A, B or C
