An exponential growth of the Internet and decreasing of telecoms’ average revenue per user (ARPU) demand a change in the access and core telecommunication network architecture.
Telecoms are now more than ever compelled to reduce their capital an operational expenses (CAPEX and OPEX), whilst at the same time provide higher level of scalability and agility of the networks.
Among telecoms there is no uniform opinion about modern, next-generation network architecture. There are many technologies and solutions which address challenges that telecoms are facing with today, but not all of them are applicable to every telecom.
Even though there are different views on the same problem that plagues telecoms, all these solutions have something in common, they go into direction of network function virtualization and software defined networks.
The objective of this master thesis is defining network services and architectural solutions of the modern access and core telecommunication networks. The architecture of the modern access and core telecommunication networks should be modular and scalable, whilst the network operational and capital expenses should be kept to the reasonable level that still provides profit to the telecoms as well as their future growth.
