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.

The Global Router allows you to connect the infrastructure in Servercore with a private network at the L3 level. The Global Router cannot be used to connect to infrastructure outside of 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 only work with the global router in the control panel.

User types and roles are supported in the service.

Principle of operation

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 global router networks. 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 operability of the entire network does not depend on the operability of a single segment. For example, if communication with one of the pools fails, the rest of the network will continue to operate.

Throughput

The global router bandwidth 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 MTU of the global router is 8,500 B.

The bandwidth between regions can be increased — create a ticket. 5 Gbit/s increase between regions is available, other options are negotiated individually.

Intra-region bandwidth can also be increased — create a ticket. All variants of increase within a region are agreed individually.

Limits and restrictions

All networks connected to the same router must not have overlapping subnets (the available IP addresses of each subnet must not overlap with the IP addresses of other subnets).

The account has limits on the number of global router objects:

  • up to 5 global routers (5 independent private routed networks);
  • Up to 50 networks in each global router;
  • Up to 50 private subnets on a single network;
  • up to 50 static routes for one global router.

To change the limits, create a ticket.

Cost

Servercore Global Router is free of charge if the bandwidth used in a region does not exceed 25 Gbps, 1 Gbps between regions.

The cost of 5 Gbit/s bandwidth increase between regions can be viewed at servercore.com. The cost of other bandwidth increase options is negotiated individually via ticket.
