Let us understand what an ultra-dense network is.Ultra-Dense NetworkThe dense networks deliver the best of the user experience to the users. This type of network allows the users to get the best result by the use of the densification. The density here can be the absolute or relative density in the networks.The user density networks increase the density too potentially beyond its range to fulfill the customer demand. In the user defined network, the capacity grows as the capacity of the base station also increases. This type of network provides users with the best of experience with the densification approach.In ... Read More

BGP stands for Border gateway protocol. It is used to exchange the routing information between the networks. It makes the internet work. It always selects the local path preference. Because of the below reasons it is choosing the path than the best path.- Firstly RIP (Routing Information Protocol) selects the path with lowest hop count.- OSPF (Open Shortest Path First) selects the path with the lowest cost. This is more important.- The best path in internet depends on how we are forwarding the traffic and to which autonomous system instead of the shortest path.- Higher local preference path is preferred.-Shortest ...

The basic building blocks of the IPsec vpn tunnelling are as follows −Authentication header − it is used to verify the identity of the sender of the data and to check whether it is altered or not. It ties data in every data packet to a verifiable signature. It is used for the purpose of authentication.Encapsulating security payload − the data in the data packet is scrambled by using the encryption technique to prevent the sniffing attacks. It ensures the confidentiality of the data as the data is encrypted and not being able to be understood by anyone except the ... Read More

The network troubleshooting tools are classified into two types −Hardware toolsThe hardware tools included in the network troubleshooting are explained below −Cable testerIt is also known as a media tester. It is used to test whether the cable works properly or not. The cable testers will confirm whether a cable works correctly and if there is a problem with the cable. Tools which are used for testing of the cable can be classified as a cable tester.Protocol analyserThis tool is used to analyse the network protocols like UDP, TCP, and FTP etc. This acts as a software as well as ...

Let us begin by learning about Virtual LAN (VLAN).Virtual LAN (VLAN)VLANs are logical grouping of devices which are in the same broadcast domain. Computers, servers, network devices are connected logically and their physical location don't matter. We use VLANs to manage traffic, to make the security improved.A VLAN is used when multiple LAN devices are connected to each other, where each can sneak into the data transmitted by two devices, can be seen by a third device and security can be breached.A VLAN will make sure that the data is kept only between two devices. It can be used to ... Read More

In simple language, big data is a collection of data that is larger, more complex than traditional data, and yet growing exponentially with time. It is so huge that no traditional data management software or tool can manage, store, or can process it efficiently. So, it needs to be processed step by step via different methodologies.The Applications of Big Data areBanking and SecuritiesCommunications, Media and EntertainmentHealthcare ProvidersEducationManufacturing and Natural ResourcesGovernmentInsuranceRetail and Wholesale tradeTransportationEnergy and UtilitiesThe Uses of Big Data areLocation TrackingPrecision MedicineFraud Detection & HandlingAdvertisingEntertainment & MediaReal World Big Data ExamplesDiscovering consumer shopping habits.Personalized marketing.Fuel optimization tools for the transportation ...

Network Address Translation (NAT) is a mechanism, through which one or more local IP addresses are translated into one or more global IP addresses. To access the local host also, the global IP addresses are converted to the local IP address.Network Address Translation (NAT) TypesThere are three ways to construct NAT. These are as follows −Static NATDynamic NATPort Address Translation (PAT)Functions of NATThe functions of NAT are explained below −Address translation for data transferThe border router is configured for NAT. The border router has two partsLocal interfaceGlobal interface.When the packets are transmitted from local host to another host in another ... Read More

Quality of service (QoS) in the case of networking implies the ability of a network to provide reliable service to the traffic over various technologies including Ethernet, wireless, IP, Asynchronous Mode etc.QOS in case of network congestion must keep in record various elements causing this congestion. It may be due to the reason of low bandwidth or high traffic on a single route. So, routing protocol being used heavily impacts the Quality of service of networking. It depends on how efficient a routing algorithm is to detect the traffic on a particular route and to choose a route accordingly to ... Read More
