General information about Servercore Global Router service

For your information

With a global router, you cannot configure network connectivity between products in different countries.You can only configure connectivity between products in regions and between regions in the same country.

A global router allows you to connect the infrastructure in Servercore with a private network at the L3 level.With a global router you cannot organize connectivity to infrastructure outside Servercore, for this purpose set up a connection via the Internet.

Through a global router, you can merge:

For smooth operation, all equipment used for the service is booked on an N+1 basis.

You can work with the global router in the control panel, via API and Terraform.

User types and roles are supported in the service.

Records of global router operations are stored in audit logs.

Working principle

A global router routes traffic between private subnets connected to it, providing L3-level network connectivity between different services and different pools.

The role of the global router is performed by a separate routing table located on multiple physical routers.For this purpose, a separate physical router is allocated and reserved in each pool that serves only the networks of the global router.These physical routers are aggregated into a single IP/MPLS routing domain.

Network fault tolerance is provided through equipment redundancy, dynamic routing protocols, and routing redundancy in the network.The performance of the entire network does not depend on the performance of an individual segment. For example, if communication with one of the pools is disrupted, the rest of the network will continue to operate.

Throughput

The base bandwidth of the global router is 25 Gbps within a region and 1 Gbps between regions.The actual bandwidth may be less and depends on the bandwidth of your server port. The maximum supported MTU of the global router is 8,500 B.

The bandwidth between regions can be increased. The maximum bandwidth size depends on the message regions:

  • between Moscow and St. Petersburg - 10 Gbit/s;
  • between Novosibirsk and Moscow - 5 Gbit/s;
  • between Novosibirsk and St. Petersburg - 5 Gbit/s.

If you need more bandwidth than the specified values, the increase is agreed individually.

The bandwidth within a region can also be increased. All intra-region increase options are negotiated individually.

To get a cost estimate and negotiate an increase, create a ticket.

Limits and restrictions

Subnets connected to the same global router must not overlap - they must not have the same IP addresses. Having the same IP addresses on subnets of the same router can cause routing problems.

Set limits on the number of global router objects:

  • You can create a maximum of 5 global routers (5 independent private routed networks) in one account;

  • for each global router you can:

    • connect no more than 50 networks to the router;
    • connect no more than 50 subnets to the router;
    • create no more than 50 static routes on the router.

To change the limits, create a ticket.

Cost

Servercore's Global Router is free of charge if basic bandwidth is used - no more than 25 Gbps within a region and no more than 1 Gbps between regions.

It pays to increase bandwidth.

You can see the prices for bandwidth increase between regions at servercore.com. The prices for 1Gbps and 5Gbps bandwidth increase between a specific pair of regions for one global router are given.The increase within the maximum bandwidth is calculated based on these prices.

:::infoFor example, you want to increase bandwidth by 7 Gbps. The price of the increase will be calculated using the formula: price for 1 Gbps × 2 + price for 5 Gbps.

:::

If an increase in bandwidth between regions beyond the maximum bandwidth is required, the possibility and cost of the increase is negotiated individually.

If an increase in bandwidth within the region is required, the possibility and cost of the increase is negotiated individually.
