Global Geolink

  • Enables geographic balancing and redundancy of traffic for environments requiring multiple sites
  • Ensures traffic goes to available sites when links or servers are unavailable
  • Manages WAN traffic saturation for optimal operations


Elfiq Networks’ Global Geolink feature brings enterprise-class multisite geographic traffic balancing for business continuity and disaster recovery optimization. With Global Geolink, organizations can design and implement infrastructures which will be resilient and will be able to process data even if sites go dark, as long as one is operating. Up to 6 physically separate sites can be made geographically resilient with this technology. This technology can be viewed as an alternative to the BGP protocol and global server load balancing (GSLB).

Should a site’s links become unavailable, key corporate services can be geographically balanced to another site to prevent any downtime and this adjustment can be done in seconds unlike BGP which can take up to an hour do the same.

A secure Geolink is created between each sites which will be used for the exchange of metrics between sites so each balancer is aware of the next one’s status, including link saturation, link availability, iDNS resources and their related metrics, ISV resources and metrics.

The Geolink must be established on private WAN links such as MPLS or over IPSec VPN tunnels.

To move the clients and application traffic between sites, Elfiq Networks’ research team developed the NATTP protocol. NATTP stands for “Network address translation transfer protocol” which runs its own protocol number on IP networks. It was created as a very efficient way to encapsulate valid traffic and modify its original path. NATTP is preferable to NAT because it removes any security risks associated with passing public traffic on private links by encapsulating the traffic so that only another Link LB unit can retrieve the data.
