This service means the combination of two and more remote offices into a unified protected and fully connected network for data exchange on the basis of TCP/IP protocol following the parameters and the rules of heterogeneous traffic transfer — Classes of Service (CoS).
This service is provided on the basis of RFC 2547 (BGP/MPLS VPNs) and RFC 2764 (A Framework for IP Based Virtual Private Networks). Geographically, the service can be rendered for a city IP VPN, inter-city IP VPN and international IP VPN
The equipment set in a client's office or collocation room is connected to a service access port at the «Golden Telecom» collocation room via dedicated line with guaranteed speed. The differential model (DiffServ Model) of QoS support based on Classes of Service is implemented in the «Golden Telecom» network.

To transfer data of various client's applications, «Golden Telecom» supports 3 classes of traffic data service:
- standard (STD) — transfer of traffic data not critical to timely delays. Traffic is transferred on the «best efforts» principle, i.e. if the network resources are free (e.g. web resources, e-mail etc.)
- premium (PRE) — transfer of traffic data critical to bandwidth. Traffic is transferred within the limits of the guaranteed bandwidth (guaranteed data delivery). For example, video and multimedia applications transfer, online access to remote corporate databases etc.
- real time (REA) — transfer of traffic data critical to bandwidth and timely delays. Minimum timely delay within the limits of the guaranteed bandwidth is assured (minimum network delay and minimum network delay variation — jitter). For example, voice transfer via VoIP technology.

Advantages of IP VPN from «Golden Telecom»
- this service is provided on the basis of the modern high-speed national IP/MPLS network and city-level MAN networks in the big cities of Ukraine
- «Golden Telecom» IP/MPL network is constructed on the basis of our own high-speed long-distance communication channels using Cisco Systems and Alcatel equipment
- provision of various service levels (Classes of Service) allows to integrate voice traffic with client's local network data and provide high-quality video transfer within your corporate network
- inexpensive routing equipment required for channel reception, since Ethernet — the most widespread protocol in local networks — is offered as the main connection interface
- our network provides fully connected corporate network structure, which will be protected against break-downs in the best possible way and will continue functioning even in case of failure on any network node
- no redundancy of the information transferred between offices
- you will only need the staff to deal with the service functions of the network and not with the provision of connectivity of the offices.

Technological characteristics
- this service is available in Ethernet (main), V.35/X.21 and G.703 interfaces
- channel speeds are divisible by nx64 Kbps in the ranges of 2048 Kbps, 4 Mbps, 10 Mbps, 100 Mbps.
- «Golden Telecom» network provides the basic level of security of the corporate network (isolation and integrity) on the level of Frame Relay or ATM networks.
