Building up IP/ MultiProtocol Label Switching (MPLS) networks for mobile communication operator Kyivstar

Project purposes

To build up IP network, using the up-to-date MPLS technology in order to solve two principal problems:

  • to get the Kyivstar network ready for introducing the third generation (3G) services;
  • to create a platform for the new independent service segment to be the basis for developing multifunctional corporate customer networks.

Solution

Through a tender, the Kyivstar Company has selected the world’s most advanced solutions. MPLS-based network has become a logical continuation of Kyivstar’s own primary network for transmitting various traffics, the packet network traffic inclusive.

Kyivstar ІР/MPLS-network has been built up through its superimposing on the existing Kyivstar high-speed network. On sites in Kyiv Cisco devices have been installed as P and P/PE routers. All the routers are simultaneously the core and periphery of MPLS-network.

When implementing the project, we have set up within Kyivstar’s MPLS-network separate Virtual Private Networks (VPN) SIGTRAN for transmitting signal traffic.

Transmission of SIGTRAN signal traffic through MPLS\VPN has been carried out with regard for reservation, i.e. via two independent routes. Each SIGTRAN unit has two physical interfaces, therefore connection to the network is multi-homed. The VPN SIGTRAN set up takes into account reservation. Each SIGTRAN unit has an output to two РЕ-routers, which ensure failure-proof mode of operation. SIGTRAN unit chooses itself which route is a basic and which is a reserve one.

Result

The newly built network has linked seven cities of Ukraine: Kyiv, Kharkiv, Dnipropetrovsk, Donetsk, Simferopol, Odesa and Lviv.

It was for the first time that Ukraine did implement Cisco IP Solutions Center 4.0, designed for managing the network and its services. The first traffic to be transmitted via the network is the Internet traffic intended for connecting corporate users.

The infrastructure has been created that enables the Kyivstar customers to enjoy the 3G services: high speed data transmission, VoIP, various multimedia services.

Specific feature of the project is that PrioCоm team has not only designed the network itself, adjusted all its elements to fit the existing SDH-network but also designed and developed MPLS-network services.

The network reliability level equals to “five nines” or 99,999% of its accessibility. This has been achieved due to the equipment used and architectural solution offered by PrioCom specialists that guarantee the operator class reliability.
