What is are the design issues with session layer?
What is are the design issues with session layer?
Design Issues with Session Layer To allow machines to establish sessions between them in a seamless fashion. Provide enhanced services to the user. To manage dialog control. To provide services such as Token management and Synchronization.
What are the protocols used in Session layer?
Protocols
- ADSP, AppleTalk Data Stream Protocol.
- ASP, AppleTalk Session Protocol.
- H.245, Call Control Protocol for Multimedia Communication.
- ISO-SP, OSI session-layer protocol (X.225, ISO 8327)
- iSNS, Internet Storage Name Service.
- L2F, Layer 2 Forwarding Protocol.
- L2TP, Layer 2 Tunneling Protocol.
What is Session Layer responsible for?
The Session Layer is the 5th layer in the Open System Interconnection (OSI) model. This layer allows users on different machines to establish active communications sessions between them. It is responsible for establishing, maintaining, synchronizing, terminating sessions between end-user applications.
What are the key design issues in case of layers?
Design Issues for the Layers of Computer Networks
- Reliability. Network channels and components may be unreliable, resulting in loss of bits while data transfer.
- Scalability. Networks are continuously evolving.
- Addressing.
- Error Control.
- Flow Control.
- Resource Allocation.
- Statistical Multiplexing.
- Routing.
What are the design issues of transport layer?
Design Issues with Transport Layer
- Accepting data from Session layer, split it into segments and send to the network layer.
- Ensure correct delivery of data with efficiency.
- Isolate upper layers from the technological changes.
- Error control and flow control.
What are the responsibilities of session layer and presentation layer?
The presentation layer is responsible for formatting and converting data and ensuring that the data is presentable for one application through the network to another application. The session layer is responsible for coordinating communication interactions between applications.
Which of the following is an example of session layer vulnerability?
Explanation: Weak or non-existent mechanisms for authentication is an example of session layer vulnerability. Other examples are spoofing and the hijacking of data based on failed-authentication attempts & passing of session-credentials allowing intercept and unauthorized use.
What are design issues in distributed system structure?
A distributed system is defined as a collection of autonomous computers linked by a network with software designed to produce an integratedcomputing facility….
| Q. | What are design issues in distributed system structure? |
|---|---|
| A. | scalability |
| B. | fault-tolerance |
| C. | clustering |
| D. | all of the mentioned |
What are the important design issues for the information exchange among computers?
It can be constructed from heterogeneous hardware and software. Scalability: Scalability of the system should remain efficient even with a significant increase in the number of users and resources connected. Security : Security of information system has three components Confidentially, integrity and availability.
What are the issues in designing a routing and transport layer protocol for ad hoc networks explain by taking examples?
The performance of a transport layer protocol is significantly affected by these constraints. Misinterpretation of congestion: Traditional mechanisms of detecting congestion in networks, such as packet loss and retransmission timeout, are not suitable for detecting the network congestion in ad hoc wireless networks.
What are the challenges and issues in transport layer protocol?
Induced Traffic:
What is the role of the session layer?
The session layer responds to the service requests from the presentation layer and then issue service requests to the Transport layer. This layer is mainly responsible for synchronization and dialog control. This layer provides the following services:
What are the service definition and protocol specifications in ISO 8327?
The service definition and protocol specifications are defined in ISO 8326 and ISO 8327. The session layer is the thinnest layer with the most negligible numbers of protocols in the OSI model. The session layer objective is to create, maintain and synchronize dialogs between transmitting upper layers.
What is ADSP (session layer)?
Session Layer uses some protocols which are required for safe, secure and accurate communication which exists between two-ender user applications. ADSP is that type of protocol which was developed by Apple Inc. and it includes a number of features that allow local area networks to be connected with no prior setup.
What is presentation layer in web application?
Presentation Layer uses session layer protocols and transport services. The session layer service’s actual user is the application layer through which the presentation layer lies between them. It has relatively few features as compared to lower layers. It controls structures and the interaction between the application programme.
