Corporate networks - the main mechanism of informatization

What is corporate computer networks? This could well be a university information environment that unites the administrative, academic, and student campus into a basic convergent transport MPLS infrastructure. In networks of this kind there are elements of "next-generation networks", so they have good scalability in the case of using optical communication channels, Wi-Fi. So, let's take a closer look at corporate networks.

Composition

These networks must have high-speed accessin the Internet, access to automated information resources, digital internal VoIP-telephony along with streaming integration into long-distance and city networks. Corporate information networks should produce educational and news TV content, process data in a distributed manner and be able to carry out mobile audio of important events. A backbone network for ensuring the interaction of networks of different divisions is the multiservice transport system for the transfer of integrated data (MTSPD). If we continue to consider the corporate network of the university, then it is on the basis of the MTSPD that the internal modern digital telephone exchange with a capacity of 10 thousand numbers functions with the possibility of streaming integration into long-distance and city networks.

Principle of operation

Workstations are connected to servers, which are subsequently combined by means of connecting equipment.

Corporate networks are being expanded throughincluding new network segments through routers, communication channels of various types, repeaters. In the Internet, the connection is possible through specialized devices and software to protect and defend the internal network from access from the outside ("hacking"). Administration of file servers and databases, special organizational and technical measures - the main way to protect information on access levels. Corporate networks are divided into virtual zones using virtual network technology (IEEE 802.1Q) to provide the required level of security.

Digital telephony

This is an extremely important element of communicationinfrastructure of the corporate network. Conversations over the phone are conducted inside the enterprise, bypassing intercity and city networks. The digital telephony system supports three types of internal users:

• analog phones;
• digital;
• IP-telephony.

Wireless connection

Such a network is necessary to provide access for users of mobile devices to the resources of the internal and global network.

Corporate networks include a wireless network controller, access points, and a server with management software.

IP Telephony

Modern system of IP-telephony in corporatenetworks includes a call management server, firewalls, IP telephones. The connection of IP telephones is performed over existing LANs directly to the distribution-aggregation or access switches. This solution allows you to quickly deploy very convenient mobile conference rooms directly in the venues.
