Discussion Chapter#9 Services of Data-Link
The Islamic University of Gaza ECOM 4314: Data Communication Faculty of Engineering Instructor: Dr. Aiman Abu Samra Department of Computer Engineering T.A.: Eng. Alaa O. Shama Discussion Chapter#9 The data-link layer of a node (host or router) is responsible for delivering a datagram to the next node in the path. The data-link layer is located between the physical and the network layers. The datalink layer provides services to the network layer; it receives services from the physical layer. data-link layer of the source host needs only to encapsulate the datagram received from the network in a frame, the data-link layer of the destination host needs to decapsulate the datagram from the frame, but each intermediate node needs to both encapsulate and decapsulate, because each link may be using a different protocol with a different frame format. Even if one link and the next are using the same protocol, encapsulation and decapsulation are needed because the link-layer addresses are normally different. Services of Data-Link: 1. Framing The data-link layer at each node needs to encapsulate the datagram (packet received from the network layer) in a frame before sending it to the next node. The node also needs to decapsulate the datagram from the frame received on the logical channel. 2. Flow control If the rate of produced frames is higher than the rate of consumed frames, frames at the receiving end need to be buffered while waiting to be consumed (processed). Definitely, we cannot have an unlimited buffer size at the receiving side. -

Catalyst Switches for Microsoft Network Load Balancing Configuration Example
Catalyst Switches for Microsoft Network Load Balancing Configuration Example Document ID: 107995 Contributed by Shashank Singh, Cisco TAC Engineer. Dec 19, 2013 Contents Introduction Prerequisites Requirements Components Used Background Information Unicast Mode Multicast Mode Configure Network Diagram Configurations Verify Troubleshoot Related Information Introduction This document describes how to configure Cisco Catalyst switches to interact with Microsoft Network Load Balancing (NLB). Prerequisites Requirements There are no specific requirements for this document. Components Used The information in this document is based on these software and hardware versions: • Catalyst 6500 switch which runs Cisco IOS® Software • Catalyst 4500 switch which runs Cisco IOS Software • Catalyst 3550 switch which runs Cisco IOS Software • Catalyst 3560 switch which runs Cisco IOS Software • Catalyst 3750 switch which runs Cisco IOS Software • Microsoft Windows 2000/2003 Servers The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command. Background Information NLB technology can be used to distribute client requests across a set of servers. In order to make sure clients always experience acceptable performance levels, Windows NLB is often used to ensure that you can add additional servers to scale out stateless applications, such as IIS−based web servers, as client load increases. In addition, it reduces downtime caused by servers that malfunction. End users will never know that a particular member server in the Windows NLB is or has been down. Network Load Balancing is a clustering technology offered by Microsoft as part of all Windows 2000 Server and Windows Server 2003 family operating systems. -

Write the address range and broadcast address for the following subnet: Subnet: 192.168.1.128 / 255.255.255.224 Address Range? Subnet Broadcast Address? 2. Check your answer with those provided by the instructor. If it is different, review the method of how you derived the answer with your group and correct your understanding. LESSON 3.2 98-366 Networking Fundamentals IPv4 A connectionless protocol for use on packet-switched Link Layer networks like the Ethernet At the core of standards-based internetworking methods of the Internet Network addressing architecture redesign is underway via classful network design, Classless Inter-Domain Routing, and network address translation (NAT) . Microsoft Windows uses TCP/IP for IP version 4 (a networking protocol suite) to communicate over the Internet with other computers. It interacts with Windows naming services like WINS and security technologies. IPsec helps facilitate the successful and secure transfer of IP packets between computers. An IPv4 address shortage has been developing. LESSON 3.2 98-366 Networking Fundamentals Network Classes Provide a method for interacting with the network All networks have different sizes so IP address space is divided in different classes to meet different requirements. Each class fixes a boundary between the network prefix and the host within the 32-bit address. -

Traffic Control for Multi-homed End-hosts via Software Defined Networking Anees Mohsin Hadi Al-Najjar B.Sc. (Computer Science), M.Sc. (Computer Science) A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2019 School of Information Technology & Electrical Engineering Abstract Software Defined Networking (SDN) is an emerging technology that allows computer networks to be more efficiently managed and controlled by providing a high level of abstraction and network programmability. Having powerful abstractions and pro- grammability via a centralised network controller provides new potential improve- ments to computer networks, such as easier network management, faster innovation and reduced cost. SDN has been successfully applied in wide area and data centre networks, and has achieved a significant improvement in network performance and efficiency. However, using SDN to control network traffic in end-host devices has not been investigated thoroughly. The research presented in this thesis aims to address this gap and inves- tigates the potential benefits of SDN for end-hosts. This thesis explores the feasibility of applying the SDN methodology to control network traffic on multi-homed end de- vices. The objective was to create a control mechanism by changing the network stack on the client in a way that is transparent to the application layer, the network infras- tructure, and other hosts on the network. In contrast to other solutions such as MPTCP, which require a protocol stack upgrade on all the participating nodes, the approach presented in this thesis allows quick and easy client-side-only deployment. This thesis presents an architecture for embedding SDN components, i.e.
