Get an Original Essay IntroductionWe are currently able to send and receive data including email, audio, or video with just the click of a button. The Internet is the fastest developing infrastructure in recent times. Numerous innovative technological inventions are changing the way we do things. However, due to these growing technological innovations, we tend to be unable to adequately safeguard our data. Lately, many transactions take place through the Internet, so an extraordinary quality computer network is mandatory for operational and secure transactions. As a result, network security has emerged as a modern problem. The field of networking is not only controlled by information safeguarding but also by numerous different fields. New technologies such as mobile technology, financial technology, cloud storage and e-commerce also require high telecommunication networks. Since these solutions store people's secret data, securing their network has become mandatory. The development of next-generation networks and the protection of critical data are necessary for the security and economic well-being of every republic. Ensuring efficient next-generation telecommunications networks is essential to the regime's tasks and strategies. Background The communications sector is an important driver of economic and social activity in Australia. Telecommunications are central to everyone's lives, while communications have always been necessary in business, the rapid adoption of telecommunications technologies is transforming business models and increasing business innovation in Australia. Telecommunications broadly includes the following activities: Telecommunications services, along with the infrastructure needed to implement those services, including free TV and cable TV. Additionally, the production and distribution of Australian content such as film, TV and print. Although the direct contribution of telecommunications to the Australian economy and employment is rather negligible, telecommunications exert a large influence on other socio-economic sectors as facilitatorssocioeconomic. growth. Many industries depend on the telecommunications sector because without it their operations would continue to be compromised. For example, the common use of e-commerce and social media; most of its impact occurs through the information, media and telecommunications industries. The deployment of a next generation telecommunications network in Australia is needed to ensure the growth of the economy and other socio-economic sectors. Below are the objectives of the Telecommunications Network (NGN) Project: Implementation of an accessible and faster telecommunications network. Ensure user acceptability. Integration of the telecommunications network with existing networks. Design Overview NGN captures a range of network designs, services, and properties in a layered architecture. Netflow /IPFIX flow records provide an integrated way to access data transmission from the next generation network. This transmission data is collected from the network using dedicated flow-enabled network tools. The transmission data is retrieved by a transmission analysis system for billing, congestion detection and network security. The transmission data is retrieved at the provider level and sent to the intrusion detection system. The Provider-edge is a router connected to the network. The particular intrusion detection system evaluates the transmission information transmitted through the provider-edge and sends an alert if an unauthorized or malicious transmission is detected. Network Layers Service Delivery Layer Technologies used in the Service Delivery Layer: VOIPVODMMSIPTV. The service layer is an abstract layer in a network architecture. Its purpose is to provide middleware that supports advanced third-party services and systems at the advanced application level. The service level offers competent servers owned by a telecom network service provider. These are retrieved via open and secured Application Programming Interfaces (APIs) via application layer servers belonging to the third-party telecommunications network service provider. The service layer also allows an interface to key networks at a lower resource level. Control Plane Layer Technologies used in the Control Plane Layer: Router The control plane is the portion of the network that transmits signals and is responsible for transmitting signals. Control packets are initiated on the router or sent to a router. The purposes of the control plane are system management and configuration. The control plane, management plane and data plane are the three simple components of a telecommunications project. The management plane and control plane help the data plane. The data plane that contains the signals carried in the existing network. The management plan contains administrative signs and is considered a subdivision of the control plan. In standard telecommunications networks, the three mentioned planes are executed in the firmware of switches and routers.SDN (software defined networking) separates the control plane and the data.It extracts the control plane from the telecommunications network hardware and integrates it into the its software. This allows programmatic access to the telecommunications network. As such, it allows for simpler and more efficient network management. Transport layer Technologies used in the control panel layer: Switch The transport layer is the layer in the Open System Interconnection (OSI) model responsible for end-to-end communication across the telecommunications network. This offers consistent communication between application procedures running onvarious hosts in a layered design of additional protocols and network equipment. The transport layer is equally responsible for providing quality and reliability to the end user. Furthermore, it is reliable for handling error correction. The transport layer allows the host to transmit and accept error-corrected information, messages, and packets across the network connection. It is the network module that facilitates multiplexing.Access PanelThe access panel, which is the lowest layer of the Cisco three-tier network representation, ensures the transmission of packets to the end-user computing devices. The access panel layer is sometimes referred to as the desktop layer, as it emphasizes joining client nodes to the telecommunications network. Access panel devices include multi-station access units, switches, and hubs. Core Network Design Core, Aggregation, and Access Layers are layers of the data center architecture. These layers are referred to broadly throughout this document and are concisely defined as follows: The Core layer: This layer provides the packet-switched backplane for all transmissions in the data center. The center layer offers connection to a series of combined elements and provides a direct three-layer strong material with no failure points. This core layer facilitates internal routing protocols, such as EIGRP or OSPF, and load balances traffic between the aggregation and site core layers using Cisco Express Forwarding hashing algorithms. •Aggregation layer modules: This layer performs vital tasks, such as embedding service modules, spanning tree dispensation, default gateway repetition, and layer 2 domain definitions. Server-to-server multi-layer traffic is transmitted on the aggregation layer. It is able to use services, such as firewall and server load balancing, to improve and protect systems. Access Layer: In this layer, servers are physically connected to the telecommunications network. These server appliances contain blade servers with core switches, 1RU servers, blade servers with pass-through cabling, mainframes with OSA adapters, and clustered servers. The access layer telecommunications network configuration includes sectional switches, integral blade server switches, and 2RU switches. The switches offer both Layer 3 and Layer 2 facilities, satisfying different server broadcast domains and administrative needs. Network Requirements To provide our buyers with additional opportunities to obtain our services, we tend to want to provide e-commerce services. to try to do this we would like a very secure network given the security level of our product. This technique can also facilitate the collection in America of different staff and prices that we are able to break down into different budgets or bonuses and even raises for our staff. We will implement our security protocols at safe levels. Our servers will be internal for any security measures. Digital certificates, SSL enhancement and therefore vulnerability scanning must be taken into consideration when adapted to this network. First we will check the DNS servers or name system servers. This interprets domain names into IP addresses. There are many to choose from, however we will have our own internal native DNS server for our secure network. We will use the Century link for our ISP and use their DNS for our unclassified network. We will have DHCP servers running on an Internet App Server. We will run the network protocols through a combination of OSPF and BGP and static routes. (Bishop) We will make non-public IP addresses for thehost machines that go through a NAT once they leave the network. We will have an area CA authority and it doesn't matter what services are required for the customer. All active hosts can have native CA authority. These certificates need to be updated often. Users will also use 2-issue authentication. This can be handled by the cyber team. Technical and commercial groups will be brought together for customer support. They will also monitor the system and prevent any problems from occurring, always as an update and will send those updates. For security reasons, we will have all internal support. Once the budget is approved, we can begin selecting and building these elements. As for planning, we will have internal servers for security measures. They would like an external firewall and a demilitarized zone, or zone, and active and passive IDS, or intrusion detection system, such as the Cisco 7030. A firewall that contains an ACL, or access management list, must also be installed as part of statement, expresses deny traffic to deny secure traffic on ports. The department can use Splunk as its computer code. It will actively monitor traffic and automate alerts for U.S. government personnel. It will jointly monitor for cyber attacks. They will also be placed in HBSS (Host Based Security System) which can cover all antiviruses and firewalls. The Network may have had the opportunity to connect with the network. The network must be filtered by the web, it must also be American state, or Data Assurance, compliant and verifiable for legal and security reasons. All traffic through the system should be DISA, or Defense Data System Agency, category compliant and therefore compliant with the ownership of the telecommunications network. OSPF and BGP are used together for many dynamic routings. The advantage of OSPF as a routing protocol is that it is open and universal across all devices. It also mechanically detects Next Hop devices. The downside to OSPF is that once their network list starts getting huge, you start to get bogged down because it's trying to keep it up to date. (OSPF)BGP is primarily used as a trunk between giant networks, however it can also be used on the server backplane on numerous servers. Its main advantage is that you will have as large a list of networks as you want. OSPF which you can use in a very native network and BGP which you would use for broader WAN routing to connect nodes, so you may want to use these 2 together. Static routing indicates virtually every single start and destination purpose. You tell it wherever you would like it to travel. The good thing is that you just have consistency. The downside is that it creates a terribly loud growl because you continually have to be forced to make changes to stay awake. It's awfully easy to manage a couple of devices, but after having many it becomes difficult to use. It will produce a bottleneck and it will not be possible to perform quality of service checks. OSPF can work mechanically jointly in OSPF if you have a tool down it will be on the next network path, in Static once down it is down. We will be victimized by Cisco routers for our scientific routing. We'll be victimization all of Cisco's tools to keep things consistent and ensure everything is compatible. Routers use routing tables to see the next hop address to which the packet should be forwarded. Routers maintain a routing table and store it in RAM. this is often used to confirm a route to a destination network. (CCNA)Microsoft allows you to issue and revoke digital certificates. These are often used to modify theSSL sessions and to prove the identity of the computer network, extranet or online website. Certificate Services runs on a certificate server of your choice. These servers are often mutually organized into 4 styles of certificate authorities. The enterprise root CA is the server at the bottom of the hierarchy for a Windows domain. Internet Infrastructure The Internet can be an international network of computing devices with distinct network addresses; scientific direction. PC devices in the telecommunications network connect to the web through an online service provider. A PC is assigned a short-lived network protocol once it connects to the web directly through an online service provider. However, PC devices have a persistent network protocol connected to the web via a spatial network. The TCP/IP stack includes: Application Protocol Layer: Allows computers to access the worldwide network, email, and therefore file transfer protocols. TCP layer: The transmission management protocol forwards frames to the destination media access management address (MAC address) using the specific port type of the PC device. IP Layer: Addresses packets to a particular PC device using its scientific address. Hardware Layer: During this layer, frames are reborn from binary type into network signals. They include local network cables, modems and Wi-Fi routers. Access Network Design Technology Telecommunication network needs the next infrastructure to connect to the dedicated Internet line: Backup Server: The network needs a backup server, so users will access the shared data only in case of any period of net time. This backup server should be strategically attached to the switch so that it is accessible to all or some licensed computers within the network. Firewall: The web association software system should have the firewall enabled to protect connected devices from malicious intrusions through the web. Additionally, you should install antivirus, antispyware, and antimalware to confirm that web access is safe. Operating system: Portable devices require operating systems for remote access sessions. Furthermore, browser software system such as Net Soul is needed as an interface for users to access the network. Ethernet: Computers must be forced to be connected to the router and backup server via a spatial network. This association is created via LAN cables. Switch: A switch is a controller, optional network devices to communicate efficiently. Through data sharing and resource allocation, switches save companies money and increase worker productivity. Justification of the technology The proposed telecommunications network is a Wide Area Network. Therefore, to function efficiently, both wireless and wired computer networking is required. Some of the major resources used to implement this telecommunications network so that it can comprehensively and efficiently serve the target demographics include: Cloud Computing: Cloud computing ensures that a large number of users can back up their information in cloud storage . Additionally, these users can share resources while on the go. It allows for faster access to information and sharing of information across target demographics. Firewalls: Firewalls use various methods to protect against intrusions. For proxy servers, firewalls mask the IP address and inhibit intrusions. External computer systems communicate with firewalls before communicating with the intended computer on a network. Therefore, i.
