Data transmission in virtual private networks (VPN)

RCNTEC is the connection provider on all territory of the Russian Federation and provides its customers the service of DATA TRANSMISSION IN VIRTUAL PRIVATE NETWORKS (VPN), both the second (Ethernet) and the third (IP) levels, providing connection ports to the points of presence of the customer. On top of the data service our company is also ready to provide cryptographic protection of traffic, as well as the services of constructiong the own customer's network or its separate parts, connecting them to VPN ports.

Service Description

1. This service means that the Operator provides the technical ability to share data between geographically separated Customer's objects. For this purpose the network connection port is given at the location of each plug of the Customer's facility. The type of connection port and its location for each object are subject are coordinated by the Operator and the Customer. The minimal number of connected objects of the Customer (minimal quantity of the ordered ports) – 2. Maximal number of connected objects is not limited. The port, selected by the Operator, for connecting to the service, is used by the client for connecting his own network equipment, which supports the relevant port type, in order to exchange data with other connected objects.

2. The data exchange in the Operator's network between the ports of the connection according to an agreement with the Customer is organized according to one of the model circuits: IPVN or L2VPN (VPLS/VPWS) on "each with each" circuit (i.e. each connection port of the Customer is available through the Operator's network with any other Customer's connection port to the service).

3. The "IPVN" scheme provides for an interaction between the Customer equipment and the Operator's network via standard network Protocol of the third level IPv4, in which a network Operator delivers IPv4 packets between the connection ports of the Customer based on the address information IPv4 (IP address), which is contained there. The IPv4 addressing used by this process, is the subject of mutual agreement between the Operator and the Customer. Routing on the joints between the network Operator and the connected Customer's equipment can be arranged by mutual agreement on the basis of static or dynamic (BGPv4) routing protocols. In the case of using dynamic routing Protocol (BGPv4) the Customer uses the Autonomous system number assigned by a regional Internet registry (RIR), or, by agreement, the Operator selects the Autonomous system number from the range reserved for private use according to RFC1930. The maximal allowed number of IPv4 routes pointing to one port connection of the Customer — 10 (for static routes) and 500 (for dynamic routes), unless the Contract provides otherwise.

4. The "L2VPN" scheme in the form of "VPLS" provides for an interaction between the Customer equipment and the Operator's network via standard network Protocol of the second level of Ethernet, in which a network Operator delivers Ethernet frames between the connection ports of the Customer, based on the address information of Ethernet (MAC-address), they contain. VLAN ID/range VLAN ID that is entitled to be transmitted over the network between the ports connecting the Customer shall be determined by mutual agreement. The maximum number of MAC addresses involved in the network communication through the network Operator for each connection port – 100 (unless the Contract provides otherwise). Transfer of service Ethernet protocol frames (STP, VTP, etc.) through the Operator's network is not performed.

5. The "VPWS" scheme is a variant of the "VPLS" scheme, used for the two connection ports of the Customer. The difference of this scheme is the absence of limitations on the amount of MAC addresses of the Customer, involved in the exchange and the transfer of proprietary protocols between the Ethernet connection ports ofthe Customer (in accordance with clause 1.4).

Specifications

In order to provide the service, the following must be defined at the stage of its connection:

1. The number and location of connection ports

2. The type of each connection port. One of the following: 10BaseT/100BaseTX/1000BaseSX/1000BaseLX or other type as agreed upon by the Operator and the Customer

3. The bandwidth of each connection port (in kbps or Mbps) for the incoming traffic to the port and outbound traffic from this port

4. The service type is IPVPN or L2VPN

5. For IPVPN service, for each connection port:

   • the routing type (static/dynamic)

   • a list of static routes (static routing) and/or number of Autonomous systems used (for dynamic routing).

   • IPv4 equipment addressing of Customer and Operator

6. For L2VPN service:

   • Magnitude/range of VLAN ID transmitted via the Operator's network between the Customer ports

   • the maximal frame size (MTU) that can be transmitted over the Operator's network between the Customer ports

7. The maximal allowable percentage ( % ) of lost packets/frame, the maximum permissible transmission delay of the packets/frames by the network Operator between the ports of the Customer

Technical specifications can be changed through the conclusion of an according agreements related to the Contract for the service rendering.
