Unit 1 network management
Network management involves configuration management, fault management, performance management, security management, and accounting management. Configuration management deals with documenting the initial setup and any changes to network entities and their relationships over time. Fault management detects, isolates, corrects, and documents issues through both reactive and proactive approaches. Performance management monitors metrics like capacity, traffic, throughput, and response time to ensure efficient network operations. Security management controls access based on policies while accounting management tracks network resource usage for billing or budgeting purposes.
Fault management presentation
The document discusses fault management and proactive maintenance in telecommunications networks. It covers topics like fault diagnosis, alarm correlation, health checks, and backup plans. The key aspects are:
1) Fault management involves detecting, isolating, and correcting faults to ensure normal network functioning. It analyzes information and abnormalities during operations.
2) Proactive maintenance aims to reduce errors and prepare for situations where faults cannot be easily fixed. This includes health checks to verify system status and software levels, as well as backup plans for major faults.
3) Other sections provide definitions of terms like faults, alarms, and explain concepts such as fault diagnosis, alarm correlation, health checks and their components, and backup verification.
Manageral aspects of software maintance
The document defines software maintenance and categorizes it. Software maintenance involves changes to software away from the previous implementation, rather than just restoring it to its original state. There are three main types of maintenance: corrective, adaptive, and perfective. Software maintenance can also be abstracted into two broad categories: corrective and enhancement. Corrective maintenance leaves functional specifications unchanged, while enhancement maintenance changes original specifications but leaves primary functions intact. The document notes that correcting bugs is a small part of actual maintenance effort, and that successful maintenance depends on gaining an understanding of the software system through reviewing code, documentation, and user requests.

Cp7101 design and management of computer networks-requirements analysis
The document discusses requirements analysis for computer networks. It defines requirements analysis as gathering and deriving requirements to understand system and network behaviors. This includes identifying, gathering, and understanding system requirements and their characteristics. Requirements can be core/fundamental requirements necessary for network success or features that are desired but not necessary. Requirements analysis results in a requirements specification and map to guide network architecture and design. The document outlines different types of requirements including user, application, device, network, and other requirements.
ANALYSIS OF NETWORK PERFORMANCE MANAGEMENT DASHBOARD
Analysis of performance availability is very important to help improve network
performance. This is due to developing services to be used by customers. In performance
availability it is known that there are many problems that occur in each event in the
field. In achieving the optimal level in carrying out the implementation and support
processes of the performance management dashboard, an analysis is needed to develop
management and control in the networking division with the aim of generating
utilization in the implementation and support processes to align with the business needs
of PT ABC. The existing reference model is a reference model that refers to the
functional area of FCAPS. The FCAPS model consists of five functional areas,
including fault management, configuration management, accounting management,
performance management, and security management. In general, companies have
implemented FCAPS on failure issues and configurations (fault and configuration).
Security / security has relied on other tools that are not integrated in the FCAPS model
as a whole. The basic principle is, even though there are five elements from FCAPS,
one element can influence the success of other elements.

In this paper, we utilize the public key based homomorphism authenticator and uniquely integrate it with random mask technique to achieve a privacy-preserving public auditing system for cloud data storage security while keeping all above requirements in mind. To support efficient handling of multiple auditing tasks, we further explore the technique of bilinear aggregate signature to extend our main result into a multi-user setting, where TPA can perform multiple auditing tasks simultaneously. Extensive security and performance analysis shows the proposed schemes are provably secure and highly efficient. We also show how to extent our main scheme to support batch auditing for TPA upon delegations from multi-users.
My Problem Dr. Shriniwas Kashalikar
The document discusses "my problem", which is a struggle within individuals between what is and what should be. This restlessness stems from sensory input not matching feelings of wants and deficiencies. "My problem" is a global issue, as it is difficult to voluntarily blossom into generous, loving, and benevolent qualities. Punishment and force cannot transform individuals, only creating a holistic environment through globally beneficial policies and practices can help with blossoming. However, even this is not possible without considering everyone through tolerance, as "my problem" is also "your problem" - it is universal. The only way to address this is through the universal practice of Namasmaran.

Freedom Dr. Shriniwas Kashalikar
The document discusses whether an individual or organization that does not participate in a political freedom movement led by another group can be considered antinational. It provides several examples of individuals who may not have participated in political freedom struggles, including artists, scientists, government workers, and those focused on other social reforms. It argues that after 62 years of independence, it is important to move past judgments of others' viewpoints and actions during the freedom struggle, and instead focus on a shared vision of prosperity and equality for all.
Unconditoned Happiness Dr. Shriniwas K Ashalikar
The document discusses the state of unconditioned happiness exemplified by saints. This state is one of equanimity amid disturbing situations, as praised in the Bhagavad Gita. It is not a state of depression, surrender, or indifference, but rather a "videhi awasthaa" state of consciousness beyond one's physical, physiological, and psychological perceptions. In this state, one appears unaffected by situations but can still interact and manifest wisdom in various subtle forms, including through scriptures or actions. The unconditioned happiness of this evolved state of consciousness is infinite and subtle, not a result of indolence or ignorance.
Dr. Kashalikar Shriniwas
Dr. Shriniwas Kashalikar was born in 1951 in Maharashtra, India. He received his medical education from BJ Medical College in Pune. After graduating, he and his brothers established a hospital in the remote village of Adeli, where he worked for three years. He then moved to Mumbai to further his studies in philosophy and science, joining GS Medical College. While there, he worked with slum dwellers, mill workers, and the visually impaired. He has written over 40 books and 500 articles on varied subjects, sacrificing royalties to make them freely available online. Currently, he focuses on interdisciplinary study, writing, research, and practicing total stress management.
Accidents Holistic Solutons Dr. Shriniwas Kashalikar
1) Accidents and other problems are caused by policies that prioritize production of private vehicles like cars and motorcycles over public transportation like buses and trains.
2) This leads to issues like increased fuel consumption, road wear and maintenance costs, pollution, traffic jams, accidents, overcrowding of public transportation and stress/tension for travelers.
3) The root cause is policies driven by private interests rather than public health; changing policies to prioritize and improve bus services would help reduce accidents and other issues in a holistic manner.
Raid+controllers
RAID controllers use multiple physical disks that appear as a single logical drive. RAID levels 0, 1, 5 are commonly used. RAID 0 stripes data across disks for speed but has no redundancy. RAID 1 mirrors data onto two disks for redundancy but is expensive. RAID 5 stripes data across disks and uses parity for redundancy, avoiding bottlenecks of RAID 4. Larger RAID groups can implement dual distributed parity for fault tolerance from two drive failures. Nesting RAID levels can boost performance by combining redundancy with RAID 0 striping. Rebuilding failed drives uses parity calculation with XOR to reconstruct lost data.
Data+security+sp10
The document discusses data security and provides an overview of key concepts including security measures, policies, principles, and technologies and threats related to data security. It covers topics such as the definition of security and data, how computers are used to store important data, sensitive information, and the threats to security including natural disasters, human errors, hackers, and more. Security services like secrecy, integrity, availability, and access control are explained. The presentation also discusses security policies and models.

Cryptography intro
Cryptography involves encrypting plaintext data into ciphertext using encryption algorithms and keys. Conventional cryptography uses a single secret key for both encryption and decryption, while public key cryptography uses separate public and private keys. The combination of these methods in hybrid cryptosystems like PGP provides both the speed of conventional encryption and the key distribution benefits of public key cryptography.
Rsa
Public Key Cryptography uses two keys - a public key that can encrypt messages and verify signatures, and a private key that can decrypt messages and create signatures. The RSA algorithm, the most widely used public key algorithm, is based on the mathematical difficulty of factoring large prime numbers. It works by having users generate a public/private key pair using two large prime numbers and performing modular exponentiation. The security of RSA relies on the fact that it is computationally infeasible to derive the private key from the public key and modulus.

- 42. CONCEPT
- 44. Concept
- 49. Components of network management on the Internet
- 50. SNMP defines the format of packets exchanged between a manager and an agent. It reads and changes the status (values) of objects (variables) in SNMP packets. Role of SNMP
- 51. SMI defines the general rules for naming objects, defining object types (including range and length), and showing how to encode objects and values. Role of SMI
- 52. SMI defines neither the number of objects an entity should manage, nor names the objects to be managed nor defines the association between the objects and their values. Role of SMI
- 53. MIB creates a collection of named objects, their types, and their relationships to each other in an entity to be managed. Role of MIB
- 54. We can compare the task of network management to the task of writing a program. 1. Both tasks need rules. In network management this is handled by SMI. 2. Both tasks need variable declarations. In network management this is handled by MIB. 3. Both tasks have actions performed by statements. In network management this is handled by SNMP. An Analogy
- 69. All objects managed by SNMP are given an object identifier. The object identifier always starts with 1.3.6.1.2.1 . Name
- 70. Internet Subnodes Any object in the internet MIB will start with the prefix 1.3.6.1. There four objects under internet object
- 72. SNMP ASN.1 Data Type

- 91. udp group
- 93. udp variables and tables
- 101. 21.5 SNMP SNMP is an application program that allows 1) a manager to retrieve the value of an object defined in an agent; 2) a manager to store a value in an object defined in an agent; and 3) an agent to send an alarm message about an abnormal situation to the manager The topics discussed in this section include: PDUs Format SNMP
