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 Components

PNMS : 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 on-site equipment for execution. Two types of PNMS can be proposed in accordance with customer’s 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 Sub-Central 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.

For 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 0011 0000 0000 0001 0010 0011 0100

195 . 0 . 12 . 34

Classifying IP address (Class A B and C)

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)

Number of Host per Network : 16,777,214 (=2^24-2)

All “0” is used to indicate the network

itself and all ‘1” is used for IP broadcast address.

Number of Networks:16,384 (=2^14)

Number of Host per Network : 65,65,534 (=2^16-2)

Number of Networks:

2,097,152 (=2^21)

Number of Host per Network : 254 (=2^8-2)

Global IP address and Private 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.

IP AddressSubnet

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.

IP AddressSubnet Mask

The Subnet Mask is used to identify the boundary of the network part and the host part in the network that divided in to subnets.

The notation of the subnet mask is similar to the IP address. The 32-bit array is divided in to four 8-bit parts, each of which then converted into decimal numbers. These numbers are arrayed in a line with dots placed between them for separation. The part where the bit stream shows continuous “1”s in the subnet mask means the network part. The subnet mask utilized for a node to check if other corresponding computers belong to the same subnet (segment).

Example : The subnet mask of an IP address whose network part consists of first 26 bits.

11111111 11111111 11111111 11000000

( 255 . 255 . 255 . 192 )

Calculation of Network Address from an IP Address and Subnet Mask : Comparison of IP address and subnet mask of the node leads to the network address. The comparison is to be done in the following steps.

IP address (Decimal) : 195 . 125 . 100 . 8

: 255 . 255 . 255 . 192

IP address (Binary) : 11000011 01000101 01100100 00001000 Apply logical AND

Subnet mask (Binary) : 11111111 11111111 11111111 11000000

Network address (Binary) : 11000011 01111101 01100100 00000000

Network address (Decimal) : 195 . 125 . 100 . 0

CIDR (classless inter-domain routing :195. 125. 100. 8/26** Indicates first 26 bits is network address (including subnet)
