Adax FastPlane – GTP and GRE Tunneling

Data Plane Acceleration for High Capacity and Performance in 3G, 4G, 5G, IoT and M2M Networks

Adax FastPlane is a high performance data plane solution supporting GTP-U and GRE tunneling that allows users to quickly implement complex data plane solutions for 3G, 4G and 5G mobile networks supporting automatic relaying between GTP tunnels, between GRE tunnels, and between GTP and GRE tunnels.

As network capacity increases so does the need for performance, security and reliability. Adax FastPlane software, and its sister product, SCTP/T, are designed to meet the exploding capacity demands of cellular networks, especially from IoT and M2M. This particularly impacts GTP-U and the encapsulation and de-encapsulation of packets, PDP context requests and responses, and packet header insertion and enhancement.

Accelerating GTP and GRE tunnels and offloading GTP data traffic is a critical requirement in the performance of cellular networks, especially for traffic management, policing and load balancing in the core network. Removing bottlenecks in the network increases performance and traffic policing improves Quality of Service.

Adax FastPlane Protocol Software Features

  • Can be deployed as a virtual network element on a variety of different commercial cloud computing providers, eg. Amazon AWS, VMware, OpenStack, MS Azure
  • Support for Multiple APNs and for Overlapping Addresses for MS devices
  • Interworking between IP and GTP-U (GTP Tunnel termination)
  • Termination and Relay per PDP context for Mobile Data Offload (GTP Bypass)
  • Interworking between two separate GTP tunnels (GTP Relay)
  • GTP-U Echo Requests/Responses can be terminated to the host, relayed to another GTP tunnel, processed automatically, or discarded
  • Can be used to implement Keyed or unkeyed GRE tunnels
  • GRE tunnels can also be configured to rely packets decapsulated from the tunnel to other GRE tunnel(s) or GTP PDP context(s)
  • Remote API Library provides loosely coupled application interface enabling user applications and GTP-C stacks to be implemented on the same machine or on different virtual machines in the cloud
  • Traffic Policing support for ingress and egress packets. Including DSCP copying and/or remarking and six different Token Bucket Traffic Policing algorithms.
  • Support for millions of PDP contexts subject to system configuration
  • Support for PDP context statistics indications
  • Support for PDP context lifetime indications
  • IPsec to GTP interworking
  • Supports GTPv1-U (GPRS Tunneling Protocol User Plane Version 1) as specified in 3GPP TS 29.060 and TS 29.281 and GRE (Generic Routing Encapsulation) as specified in RFC 2890 and RFC 2784
