Tessares’ MPTCP Hybrid Access Gateway (HAG) software is a highly efficient TCP to MPTCP proxy developed by the creators of the MPTCP protocol, enabling short or long-lived multi-path aggregation.
Tessares has followed the industry standards from the Broadband Forum (BBF) namely TR-348 Hybrid Access Broadband Network Architecture and its L4 Multipath Architecture using Multipath TCP. The HAG follows the TR-378 Nodal Requirements for Hybrid Access Broadband Networks and its implicit mode, using the HAG as a transparent proxy.
Tessares actively contributes to the IETF draft 0-RTT TCP Convert Protocol in relation to BBF explicit mode and the 3GPP release 16 (ATSSS).
The HAG provides a set of alarms, and exposes metrics and counters through northbound interfaces:
The HAG can give priority to one of the two access networks, usually the fixed one, enabling the least cost network first, and then overflowing to the second network if more capacity is needed by a subscriber.
The HAG can limit the aggregated bandwidth of the two networks, enabling the same speed package for many subscribers whatever their fixed line profile. Find out more in our ABL example.
The HAG is available as a virtual machine (VM) image to be deployed on bare metal or a cloud environment. The VM having the advantage of being easy to update / upgrade, or duplicate if more instances are required.
Blacklisting servers or services is possible based on the 5-tuple.
Blacklisting is useful if some traffic does not need to be proxied to MPTCP, or if the speed of some services does not need to be boosted.
