Data migration technique is used in organizations when the systems are upgraded or a makeover is done. Data compression technique reduces the time taken for transferring the data the storage. This technique is used for transferring the data between two end systems bade on specified format. In this paper we will look into the migration types and various compression techniques followed for transferring the data.

Brief on data migration and data compression techniques:

We use certain simulation codes for transfer of the data and various parallel compression algorithms are used for sending the data in a specified format at particular bandwidths. . In application migration we use this technique where is the platform is changed and the data migrated supports each model in the new transformation. In data migration the transfer of data is checked in a parallel mechanism whether the data has reached correctly in the specified format in the end system.

We use ROMIO implementation which employs two phase input output method for transferring the data which is the best parallel mechanism technique used. The data compression we find lossless and lossy compression methods. In data compression technique snapshot is stored which is used for simulation of data of the image and to make future visualizations and analysis. If any crash occurs we can restore from the point where the crash occurred using a checkpoint. Based on the requirement we follow client side compression method or server side compression method for transferring the data between the end systems.

Applications and Advantages:

As the data is transferred in a parallel mechanism there are very less chances for errors to occur and it verifies whether the data has reached in a specified format or not. By using compression technique we can transfer huge data by compressing which saves the storage space and the increase the transfer rate. These are used when there is change of servers or transformation of applications and these are used in internet for processing data.

Introduction to Enhancing Data Migration Performance via Parallel Data Compression Seminar:

Data migration is the process of transferring data between two computer systems in a specified format. Data migration technique is used in organizations when the systems are upgraded or a makeover is done. Data compression technique reduces the time taken for transferring the data the storage. In this paper we will see how data migration technique works and the use of data compression technique for transferring the data.

Brief on data migration and data compression techniques:

Data migration technique is employed based on the migration purpose, in database migration when the server is updated there is need for transformation of data and this does not affect the behavior of the application. In application migration we use this technique where is the platform is changed and the data migrated supports each model in the new transformation. In data migration the transfer of data is checked in a parallel mechanism whether the data has reached correctly in the specified format in the end system.

We apply data compression techniques so that the data gets compressed and it can be transferred easily and requires less storage space. The data compression we find lossless and lossy compression methods. In data compression technique snapshot is stored which is used for simulation of data of the image and to make future visualizations and analysis. If any crash occurs we can restore from the point where the crash occurred using a checkpoint.

Applications and Advantages:

By using this technique we can transform huge data without any errors and it does not vary the behavior of the new application. By using compression technique we can transfer huge data by compressing which saves the storage space and the increase the transfer rate. These are used when there is change of servers or transformation of applications and these are used in internet for processing data.

Introduction to Technical Seminar Topic on Data Everywhere Dealing Data from Sensors Network:

The paper is about dealing with the data and also in detail about sensor network. This includes the introduction, background, network aggregation, network storage the architecture of the sensor networks and much more.

We can define the sensor network as, continuous collection and also communication of the data string to the database. In real life the applications can be seen in tracking the phenomenon such as climate, which also includes finding the concentration of the contaminants, also the building structure including the response to the earthquakes.

The sensor network will operate as the black-boxes which are capable of recording the diagnostic data, also capable of the performing data, includes history of object which can be used in different vehicles, mobile phones and also computers.

The work done by the sensor network includes the gathering techniques of the data with the use of the various network primitives, also involves the data cleaning techniques and the methods followed are cleaning, also the querying of the noisy data, handles the incomplete data and also the sensors with errors.

The limitations include the usage of the battery with the limited life, also can create problem in case of the wide storage and when using the data handling algorithms with the high processing capacities. The limitations can also depend on the availability of the resources and packet loss in case of the data transmission.

The two phases involved in the data aggregation includes the distribution and collection phase. In the distribution phase, the query is distributed at each and every node in the network. In the collection phase, the parent is capable of collecting data at each and every child in specific intervals of time.

In this paper we have made a survey on the storage and also in gathering of the sensor data, various techniques in cleaning of the data, also the architecture of the sensor streams.

Introduction to Routing And Remote Access Services For Windows NT Server Presentation:

The operating system Windows NT Server 4.0 provides the two important services named the Remote Access Service and also the Multi-Protocols. These services are capable of creating a number of new opportunities for many vendors of independent software and also the hardware, also involves system integrator  and also network managers are responsible for providing the networking solutions for the branch office executives and also the network deployments. 

With the usage of both RRAS and also the Windows NT server the hardware vendors can provide network access solutions. The Windows NT server is considered as the network operating system and the hardware vendors will provide the networking products. This can be considered as an important application of the PC industry model for the networking business.

We can consider the Windows NT server as a networking and also the platform of the communication. When we consider RRAS it is capable of providing the elements to the above platform. So of the elements include the DHCP Relay Agent for IP, RIP and SAP for IPX, Static routing, API, Compatibility with LAN and WAN Cards.

Introduction to Technical Seminar Presentation on IP Telephony:

The paper is about the implementation of the IP Telephony. This paper gives the brief description about the IP Telephony, the advantages with the implementation of the telephony, also the challenges which are faced with its implementation and also includes about the users, its business aspects, the issues related to the security and its applications are discussed.

The modern requirements in the telecommunications are increasing extremely, so that the uses of telecommunication networks are experiencing a noticeable change. Currently the usage of telephonic lines is being used, more for the data transfer than for the ordinary voice related calls.  

There is a lot of burden on the networks and also the operators which are providing the services. In order for providing the services i.e. to meet the customer requirement the networks are shifted from their services of circuit switching to that of the packet switching networks. This can be implemented in the communication network also the data communication network using IP Telephony.

The concept of the IP Telephony is that the voice and also the fax calls will be transmitted over the IP network i.e. via the internet instead of transmitting over the traditional PSTN. The main difference that exists between the internet and PSTN is their implementation of their switching architectures. The internet works on dynamic routing and PSTN works on static switching methods. The advantage of implementation of IP Telephony is its cost effectiveness, the minimum access charges, its support to the new services, its effective backbones.

The implementation of VOIP, in various forms will give a many complex questions that the consumers will be able to use their communication of the telephone calls in a cost effective way or not. The IP technology plays an important role in multiple businesses in world of the peer-peer communications. We can conclude that the IP Telephony plays a vital role in modern communication.

Introduction to Technical Seminar Presentation on Broadband ISDN:

The paper is about ISDN. The paper includes the various broadband services and their history, various concepts of ISDN, ATM, its configuration and services, the benefits and limitations and also other technologies are discussed.

In general the quality of the service will depend on several factors including the cost, integrity of the data, the capacity of the utilization, providing security, also includes privacy of data along with the feature of the integration.

In order for overcoming many issues of providing the inefficiency in the network, the inefficiency can be in providing services related to data transmission to larger distances which is a complex situation. The break down in the services can also create problem, we have come up with broadband services.

The ISDN is considered as a technology which is capable of providing the network services which are cost-effective with the usage of the public telephonic network. In the network application ISDN is considered as the important phase so that the increasing demand can handle data communications in the computers.

The term ISDN is defined as the integrated digital network which makes use of the digital switches and the paths, for providing different services ex: includes the telephonic and data. ISDN it permits various sources including the voice, data, text and also the other source material transmission which can be on telephonic wires which are existing.

We can conclude that when we use the ISDN, there are many advantages for improving the sound quality and also provides features including call hold, caller id, call waiting more efficiently. And it enables both voice and also the data transmission to occur at the same time, It is also capable of sharing the multiple devices with in a single line. The disadvantage of ISDN includes the cost implementation for wiring, more service charges, and also includes limited availability.

Introduction to Technical Seminar Presentation on Composite Call:

The paper is about the composite call. When we consider the operating systems calling a system service involves the heavy-weight operation because of the protection domain crossing. In case of the distributed systems the remote services invoking is more costly when compared to that of invoking the local systems; this can be due to the network latency and also the processing overhead.

The composite call pattern is capable of executing the repeated sequences of the service calls and also the simple control structures in a safer way.  The pattern is called as BATCHING.

In simple words a composite call is defined as the program which is sent by the client to be executed in the server domain. It is capable of composing several separate calls to a single call in a server.

It is proved experimentally that though the implementations of the composite call mechanism, gives the high performance analysis should be done carefully.

Cases the problem that arises can be more than that of the performance gain we get. The experiments are still being conducted on the distributed services for providing the greater speedups.

Introduction to Technical Seminar on Echo Cancellation:

The paper is about Echo Cancellation. The types of echo include the Acoustic echo and the Hybrid echo. Echo cancelers are used as the transmission equipment in case of complex networks.  The new digital network has reflected an efficient change in the operation of the echo cancelers  The network operators which were implementing echo cancellation across the networks are capable of improving the call quality so that the network performance can be increased and also results in reducing the subscriber churn.

The types of echo include Acoustic Echo: which is generated using Analog as well as the digital handsets, the degree of the echo depends on the type and also the quality of the equipment which is being used. Hybrid Echo: it is generated electrically, which are created as the voice signals and are transmitted over the network via the hybrid connection so that the electric energy is reflected back to the speaker from the circuit.

When the Analog and digital phones are being operated on hands-free mode then apart from the acoustic echo even the background noise is also generated by the network. These additional sounds are captured by the microphone either directly or indirectly and multi-path audio is created and then the audio is transmitted to the talker back once again. The digital processing delays and the technique which is based on speech compression are responsible for the echo generation and the quality of voice can be affected in case of the wireless networks.

We can conclude that the Echo cancelers are used as the transmission equipment in case of complex networks.  The new digital network has reflected an efficient change in the operation of the echo cancelers.

Introduction to Technical Seminar on Mesh Algorithms in Parallel Processing:

The paper is about parallel processing. Parallel processing is defined as processing of the tasks with several processing units or with number of processors. Generally the powerful computer for sharing the jobs contains more processing units.

Operations which are done simultaneously take less time for computation so that more tasks can be done. Generally a task is divided into subtasks. And the operations of subtasks are done at the same time on different processors. These subtasks are then joined to form a task i.e. a solution to the original problem. Thus we can conclude that parallel processing is used for increasing speed.

The speedup equation is given by speedup = ws/wp where ws denotes the worst case running time of fastest sequential algorithm and wp denotes the worst case running time of the parallel algorithm for the same problem.

A mesh algorithm is defined as, a x b grid which has processor at each grid point. And each processor of mesh is defined as a tuple (i, j),where 1 £ i £ a and 1 £ j £ b. Also each processor will be having a RAM with local memory. At the same time each processor is capable of making calculations related to manipulation like addition, in one unit of time.

The packet routing is defined as the communication with in a process in a fixed connection network. Where the processor has information regarding the other processor it has to be delivered to.

We can conclude that, parallel processing is used in research and development areas. The mesh algorithms discussed in the paper increases the performance of the parallel algorithms.
