What are corporate computer networks? It may well be a university information environment that combines administrative buildings, academic buildings, and also a 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 should have high
- speed
Internet access, access to automated
information resources, digital internal VoIP-telephony along with stream integration into long-distance and city networks. Corporate information networks should produce educational and news TV content, process data in a distributed manner and have the ability to mobile audio support important events. The backbone network for ensuring the interaction of networks of various departments is a multiservice integrated data transmission system (MTSPD). If we continue to consider the corporate network of the university, it is on the basis of MTESD that the internal modern digital telephone exchange with a capacity of 10 thousand numbers operates with the possibility of stream integration into long-distance and city networks.
Principle of operation
Workstations are connected to servers, which are subsequently combined through connecting equipment.
Corporate networks are expanding through the inclusion of new network segments through routers, communication channels of various types, repeaters. Internet connection is possible through specialized devices and software to protect and protect the internal network from outside access (“hacking”). Administration of file servers and databases, conducting special organizational and technical measures is the main
way to protect information by access levels. Corporate networks are divided into virtual zones using virtual network technology (IEEE 802.1Q) to provide the desired level of security.
Digital telephony
This is an extremely important element of the communication infrastructure of the corporate network. Telephone conversations 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 ensure access of mobile device users to the resources of the internal and global networks.
Corporate networks include a wireless network controller, access points, and a server with management software.
IP telephony
The modern IP-telephony system in corporate networks includes a call management server, firewalls, IP-telephones. Connection of IP telephones is carried out via the existing LAN directly to the distribution-aggregation or access switches. This solution allows you to quickly deploy very convenient mobile conference rooms directly in the venues.
