Question One

In your own words, differentiate between modern Telecommunication Network (based on Telephone Infrastructure) and Data Communication Network. Your answer should contain at least 6 to 8 lines.

Question Two

Consider an example of a department in a University with six instructors (3 males and 3 females). The instructors are ranked from 1 to 3 where 1 being the lowest rank and 3 being the highest rank, respectively. Write an ASN.1 description for record values with appropriate data types for the provided cases.

Question Three

Provide the Object Identifier for the internet, mgmt., private, mib-2, interfaces, icmp, udp and snmp nodes according to the Internet MIB-II group.

Paper For Above Instructions

The differentiation between modern telecommunications networks and data communication networks is essential to understanding the evolution of communication technology. Modern telecommunications networks, primarily based on telephone infrastructure, have traditionally focused on voice communication. These networks use circuit-switching technology, where dedicated communication paths are established for phone calls. In contrast, data communication networks, which emerged later, are designed for data transfer and leverage packet-switching technology. This allows for more efficient use of bandwidth, as multiple data packets can be transmitted simultaneously over the same medium, leading to enhanced speed and capacity. Additionally, while telecommunication networks often require specialized hardware and protocols, data communication networks are generally more flexible, accommodating various forms of data traffic including video and file transfers. The integration of both types of networks has led to the convergence of services, enabling voice over IP (VoIP) and multimedia communication, thus blurring the lines between the two distinct categories.

In considering the university department of six instructors (three males: George (rank 1), Lee (rank 3), and Ali (rank 2); three females: Olivia (rank 3), Rosy (rank 1), and Benny (rank 2)), we create an ASN.1 description for the InstructorData type. Here is a sample ASN.1 specification:

InstructorData ::= SEQUENCE {


name            UTF8String,


rank            INTEGER (1..3)


}


MaleInstructors ::=


SEQUENCE OF InstructorData


FemaleInstructors ::=


SEQUENCE OF InstructorData


CaseA ::= SEQUENCE {


alphabeticalList     SEQUENCE OF InstructorData


}


CaseB ::= SEQUENCE {


sortedRanking SEQUENCE OF InstructorData


}


CaseC ::= SEQUENCE {


groups SEQUENCE OF SEQUENCE (2) OF InstructorData


}

In this specification, we outline the data types for male and female instructors, and different approaches to organizing that data alphabetically and by rank. Each instructor's record consists of a name and rank.

Now, regarding the Object Identifiers (OIDs) for the given nodes of the Internet MIB-II group, we will present the identifiers as follows:

  • Internet: 1.3.6.1
  • mgmt: 1.3.6.1.2
  • private: 1.3.6.1.4
  • mib-2: 1.3.6.1.2.1
  • interfaces: 1.3.6.1.2.1.2
  • icmp: 1.3.6.1.2.1.5
  • udp: 1.3.6.1.2.1.7
  • snmp: 1.3.6.1.2.1.11

This structure provides a clear definition of the management and operational parameters defined in the MIB-II group, which is crucial for effective network management.
