In this chapter, you will learn about network services and their explanation including examples, uses, and benefits. You will get a comprehensive knowledge of network services after studying this lesson. The network is applicable in many areas whether these areas are known to you or not. Modern society likes technology-based applications of networking which play a significant role in daily life. For example, a wide range of networking is used in phone calls and messaging and it allows us to get several benefits within different areas.

You can apply network services in different levels of work to get more benefits than basic functions. It is an effective way to contribute a high level of services by using the least amount of dependability, performance and specific security.

A network explains a system that interconnects devices to build communication for exchanging resources and services by utilizing some common standards. For example, the network plays an important role in achieving professional success. The internet is a great application of networks to build communication within the world. The network is one of the easiest ways to spread your network to create or maintain relationships with your family, relatives, friends, colleagues and desired persons.

WAN (wide area network) optimization: Sometimes, the company’s WANs face performance issues due to constraints of bandwidth and latency. WAN optimization services involve different techniques to prevent them by including protocol optimization, reduplication, local coaching, compression, and traffic shaping. Generally, WAN services help to connect computers placed at a large distance and even miles apart. WAN service can be owned by multiple owners and can be administered to the public globally.

WAN can include the connections involving the company’s headquarters, cloud services, branch offices, benefits of colocation and other benefits. WANs are not limited to the same geographical position. The company WANs support users for sharing services, access to applications and other types of resources that are centrally located. WAN connections can include wireless and wired technologies. Wireless technology of WAN connection can involve cellular data networks such as Fi, 4G LTE or satellite network services. The expanded security is essential and it depends on where the end-users are working. The end-users of WAN should use antivirus software and firewalls to resist unauthorized compromises or access to their devices.

Interconnection: If you want to exchange data, resources or digital information directly, privately and securely within your business, interconnection strategy is the perfect option for you. When companies need to make a connection with customers, clients, and employees for collaboration or exchanging data globally to create value within their business, they choose many-to-many connectivity which exists within interconnection services. It helps them to make a connection with different resources and devices simultaneously and instantly. It results in a smooth and fast transaction according to their business needs.

Interconnection involves one-to-one or one-to-many connection, direct and personal connections to deliver the most secure and the best performance. By creating digital ecosystem density, an interconnection provides many-to-many connectivity when the parties are located within proximity. Interconnection is essential at exchange points of distribution of company, networks service providers and so on as they want to collect and create personal and low-latency connections by using their clouds, digital ecosystem, users, data repositories, employee’s and whatever their essential to run their business.

SD-WAN (Software-Defined Wide Area Network) : It is a virtual WAN technology. It helps to distribute network service across WAN by using SDN (software-defined networking) which helps to find out automatically the most advantageous method to route traffic within the data center sites and branch offices. Companies choose SD-WAN services to hold any combinations of transferring services such as LTE, MPLS and broadband internet connection between users and applications. By using a centralized control function, SD-WAN services direct data and resources with security and intelligence. It develops application performance, by increasing business productivity, user experience and reducing IT cost.

MPLS (Multiprotocol Label Switching): It helps to speed up and shape network traffic flows. The companies can forward data buckets t layer 2 the switching level rather than passing to layer 3 router level when they choose MPLS services. In late 1990, MPLS was made as a more effective option than traditional IP (Internet Protocol) routing. When the companies and service providers want to define LSPs for the implementation of QoS (Quality of Service), they apply MPLS.

MPLS can fulfill specific service level agreements related to downtime, traffic latency, and jitter packet loss. MPLS also assists in classifying traffic and also to make VPN (Virtual Private Network), virtual leased lines and virtual private LAN (Local Area Network). Moreover, it is not tied to any specific transport medium or protocol. It assists in transferring services over Ethernet, IP, ATM (Asynchronous Transfer Mode) and frame relay or any of these agreements to make an LSP (Local Strategic Partnership). GMPLS (Generalized Multiprotocol Label Switching) develops the MPLS services to handle lambda switching, TDM (Time-Division Multiplexing) and other kinds of switching technologies.

Ethernet Private Line Network : You can choose EPL (Ethernet Private Line) network services as high efficiency and cost-effective solution if you have businesses within two or more different locations. It helps to replace traditional TDM (Time Division Multiplexing) by connecting CPE (Customer Premises Equipment) with UNI (User-to-Network Interface) which is cost-effective. It doesn’t traverse the public internet. EPL service is a close date transferring service maintaining security inherently involving no encryption needed. You can use it within a bandwidth speed ranging from 10 Mbps to 10 Gbps.

EPL gives a unique QoS (Quality of Service) without sharing services and always following the direct network path. It is used within the business by providing reliability and security for different applications such as file sharing, video conferencing, credit card processing, Ethernet VOIP and data back-up. It can be structured to carry video, internet, voice and data services collectively over the same connection of EPL services. EPL service also termed as Metro Ethernet, Point-to-point Ethernet or Carrier Ethernet Service.
