Description

Technical Field [0001] The present invention relates to a network system and a data transmission method for efficient data transmission,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a network system, and more particularly, to a system structure and a data transmission method for efficient data transmission in a next generation network such as a 5G, IoT, and a smart grid.

Next-generation services are evolving into a ubiquitous environment for providing high-quality, high-quality services that are user-oriented. In the next generation network, various wired and wireless access technologies and Trillion nodes are required to be accommodated. In particular, such requirements and QoS guarantees are required.

In existing networks such as LTE (Long Term Evolution) and the Internet, there are various methods for data transmission and depend on wireless connection technology.

The existing 4G standard of 3GPP, a mobile communication network standard organization, has an evolved packet core (EPC) core network. EPC includes P-GW and S-GW for providing mobility of the terminal, billing, interworking with the PDN (Packet Data Network), and is connected to the eNodeB of the access network.

EPC uses a tunneling protocol called GTP (GPRS Tunneling Protocol) between eNodeB and S-GW and between S-GW and P-GW to provide mobility of the terminal. However, the use of GTP causes an increase in overhead due to a new IP address mapping for tunneling and encapsulation and decapsulation operations, There is a problem.

Mobile IP is a technology for providing data transmission and mobility of terminals in the Internet. Mobile IP provides terminal mobility through IP address management and control mechanisms in IP-based Internet networks. Mobile IP, however, has a problem of overhead due to the triangular problem, high latency, encapsulation, and encapsulation & decapsulation process from the operation mechanism, There is a problem that the load increases.

While the importance of inter-network routing is growing as the Internet spreads around the world, current routing architectures have many problems because they can not accommodate various requirements in terms of service quality and users. In order to handle a large amount of traffic in a 4G network, a change in the current Internet routing architecture is essential.

One of the problems of the existing Internet routing architecture is the scalability of the network. Network scalability includes system capacity, packet switching capacity, and topology of the entire network. Since the volume of the traffic volume of the network is explosively increasing, much overhead is generated in routing information between routers.

Currently, the Internet routing architecture is overloaded. Currently, the routing protocol is switched to MPLS (Multi Protocol Label Switching) and VPN signaling protocol. In order to operate as a signaling protocol, the router maintains additional state information , It is necessary to always know whether or not the corresponding mechanism of the entire router is supported. Therefore, there is a lot of overhead in terms of performance and complexity, which is a burden on the routers constituting the network.

There are many problems in determining the routing architecture. Most of the policies are determined temporarily within each autonomous system (AS), so the consistency of the policies between the routers is not completely managed and the policies are executed in a consistent manner. There is also a problem that a network model that can be used does not exist at present.

In a conventional router, MPLS (Multi Protocol Label Switching) operating in the 2.5 layer of the OSI-7 layer has a process of swapping labels for data transmission for each router. It is possible to solve the problem of an unnecessary process occurring in a process of swapping between routers.

In order to solve the problems of the existing routing architecture in the present invention, the routing architecture should be considered by accommodating the quality of service for various requirements and user's various demands.

The architecture for determining the routing architecture in the present invention must first be independent of the network topology, and the routing architecture must be able to maintain the policy independently for the policy for the routing information and the traffic control.

In addition, although the existing routing architecture does not consider the mobility of the network, the present invention needs to consider the network-level mobility of the routing architecture, Provide a mechanism to control and manage the flow. That is, it should be able to detect and remove congestion points in the network, and be able to receive or reject traffic based on the traffic classification policy.

In addition, since the data delivery method according to the present invention delivers packets to a predetermined optimal path, the order of the packets transmitted from the receiving end is not changed, and the performance of the reassembly tasks can be reduced.

Since the Internet will be a time when multiprotocol will exist in the next few years, the routing architecture in the present invention should be able to operate flexibly irrespective of the protocols used without imposing restrictions on any one protocol.

While the present invention has been described with reference to several preferred embodiments, these embodiments are illustrative and not restrictive. It will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit of the invention and the scope of the appended claims.
