What is a disadvantage of networking?

Disadvantages. Purchasing the network cabling and file servers can be expensive. There is a danger of hacking , particularly with wide area networks. Security procedures are needed to prevent such abuse, eg a firewall .

What is NGN network concept?

A Next Generation Network (NGN) is a packet-based network able to provide services including Telecommunication Services and able to make use of multiple broadband, QoS-enabled transport technologies and in which service-related functions are independent from underlying transport-related technologies.

What are the components of next generation networks?

The NGN is characterized by the following fundamental aspects:

• Packet-based transfer.
• Separation of control functions among bearer capabilities, call/session, and application/ service.
• Decoupling of service provision from network, and provision of open interfaces.

Why do we need NGN?

The NGN aims to provide high-quality broadband communications by controlling the quality of service (QoS) on an end-to-end basis. The idea is to provide multiple QoS classes having different features and to enable the appropriate QoS class to be selected when an application is provided.

What is the advantages and disadvantages of networking?

Computer Network Advantages and Disadvantages Comparison Table

The basis of comparison	Advantages of computer networks	Disadvantages of computer networks
Price	Inexpensive	Expensive
Operating cost efficiency	Efficient	Inefficient

What is the concept of next generation?

Meaning of next-generation in English used to describe a product that has been developed using the latest technology and will probably replace an existing product: More powerful, next-generation systems are coming onto the market all the time.

Why next generation network is important?

NGN enables unfettered access for users to networks and to competing service providers and services of their choice. It supports generalised mobility which will allow consistent and ubiquitous provision of services to users [ITU-T Recommendation Y.
