Research of Services of Communication Operators for Creation of Corporate Data Transmission Networks

Abstract

The article discusses various ways to connect and build corporate data networks, explores their features and capabilities. In particular, the typical range of services of telecom operators, their features, and the possibilities of their use in a corporate data network are examined. Methods of connecting to data networks include: dial-up access, physical leased line, digital leased line in the telecom operator's network. All these communication channels have positive and negative sides, both in the speed and quality of communication, and in the cost and recovery methods. This article discusses the most universal and accessible type of communication - L3 Multiprotocol Label Switching multiprotocol label switching (MPLS) / Virtual Private Network - virtual private network (VPN) solutions for combining networks at the IP level or L2 MPLS \VPN solutions for combining networks at the IP level link level. If it is necessary to encrypt Ethernet traffic, special solution requires the installation of additional high-performance network equipment.
