But a new technology called Multiprotocol Label Switching (MPLS) is changing all that. With MPLS, you can support all the above applications on an IP network without having to run large subsets of the network with completely different transport mechanisms, routing protocols, and addressing plans. Although the standard is a work in progress, many vendors and service providers are announcing MPLS products and services. As such, now seems like a good time to learn how the technology works, how it can be deployed, and what issues still need to be addressed. MPLS operates at an OSI Model layer that is generally considered to lie between traditional definitions of Layer 2 (data link layer) and Layer 3 (network layer), and thus is often referred to as a "Layer 2.5" protocol.
How use Direct Connect behind a firewall/router in Active Mode instead of Passive 1. Determine your WAN IP address and your LAN IP address; this can be done either by using winipcfg.exe or ipconfig.exe in my case looking on the status page of my Linksys router configuration. 2. Now set up DC by going to settings connection and marking the block use Direct Connect in Active Mode, In the force DC to accept connections on this port: I have 412 (I’m not sure if this matters but it has worked for me) you may want to play around with it a bit but I believe it has to be a port between 375-425 because these are the ports Direct Connect has to have open to function in Active Mode. 3.
Wireless LANs provide all the functionality of wired LANs, without the physical constraints or the wired connection itself. Wireless LAN configurations range from simple peer-to-peer topologies to complex networks offering distribution data connectivity and roaming. Besides offering end-user mobility within a networked environment, wireless LANs enable portable networks, allowing LANs to move with the knowledge workers that use them. One of the aims of the project is to illustrate suitability of a wireless LAN for the in use today. This will allow us to gain a more fundamental insight in the possibilities and restrictions of wireless LAN.
You will learn what happens when a device on one network does not know the MAC address of a device on another network. You will learn that Reverse Address Resolution Protocol (RARP) is the protocol a device uses when it does not know its own IP address. Lastly, you will learn the difference between routing and routed protocols and how routers track distance between locations. You will also learn about distance-vector, link-state, and hybrid routing approaches and how each resolves common routing problems. In networking, there are two addressing schemes: one uses the MAC address, a data link (Layer 2) address; the other uses an address located at the network layer (Layer 3) of the OSI model.
Table of Content Conclusions 3 Mesh, Bus, Ring and Star Topologies 4 Ethernet, Token Ring, FDDI and Wireless Technology 7 Conclusions 10 Reference List 11 Introduction The four topology’s for networks are Mesh, Bus, Ring and Star. The different network topologies determine how data will be moved throughout the network. This paper will explain how each of these topologies is different and what advantages each one has over the other. This paper will also explain how the different topologies have disadvantages when implementing them. It is important that each topology be understood so that the best network configuration can be chosen by an IT professional.
Wireless Networking The term wireless networking is a technology that enables two or more computers to communicate using standard network protocols without network cabling. The industry standard mainly used for wireless networking is IEEE (Institute of Electrical and Electronic Engineers) 802.11. What this standard is could be described as a wireless network with hardware that requires the use of technology, which deals with radio frequencies as well as data transmission. There are two kinds of wireless networks, Ad-Hoc (Peer to Peer), or access point (base station). Ad-Hoc (Peer to Peer) consists of a number of computers each equipped with a wireless networking interface card.
To do this the machines have to be connected in some way that allows communication, and have an agreed upon a language to talk when they do communicate. Components of a network might include individual hosts, some form of communications hardware, a network protocol and a collection of network services. B) Individual hosts A network is a collection of individual machines sometimes referred to as hosts. Each host (computer) must have some unique identifier that allows other hosts to talk to it. 1.2 COMPONENTS OF A NETWORK A) Network Protocol In order to communicate the parties must speak the same language.
Through this case study I am going to be investigating the different wireless communications that are available, and also how they could benefit Staffordshire Health Authority. I will look at previous and current wireless standards, their differences and the speeds they can provide. I will also consider the best standards to use when working with a network to support VoIP (Voice over Internet Protocol). Throughout the case study I will talk about the technologies that could work within our network environment, and others that would not be suitable or effective. Finally I will look at VoIP and how it will impact on Staffordshire Health Authority.
1.0 INTRODUCTION For mini project of this subject, I choose to analyze performance management of different Wi-Fi based on context Wi-Fi service provided in my house area which is SriPuteri WifiNet. To analyze the performance management, I have to identify the problem statement, scope and method to use. In Local Area Network (LAN), although multiple device such as PC, laptop, mobile phone and many more can connected to Wi-Fi but as the increasing of device used, the network can become slower because of data traffic congestion. To overcome the problem, it is essential to have a good Network Management plans. In Network Management, there are three main aspects that must considered which is Security, Performance and Reliability.
Handover Management in NGN Abstract— The demands of network users for better, faster and secure services are ever increasing. The field of mobile networks is most dynamic in the world of networking. The Handoff Management in Next Generation Network has been a topic of interest for many researchers in the modern era. Handoff plays a vital role in NGN by providing connectivity without losing connection from one network to another. Different algorithms and techniques are used to for the Seamless handoff and to optimize handoff delay and data loss.
