Abstract
In general, techniques are described for facilitating interchassis redundancy (ICR) among heterogenous mobile gateway member chassis that provide high-availability services as an group to one or more mobile subscribers. In one example, a member chassis of the mobile gateway comprises a control plane having a plurality of distributed subscriber management service units that serve as anchors for subscriber sessions. A redundancy group defines a backup association between one of the subscriber management service units and a subscriber management service unit of another member chassis of the mobile gateway. A routing unit of the member chassis comprises a resource manager that negotiates parameters for a communication channel for the redundancy group. A session management daemon establishes subscriber sessions anchored by the subscriber management service unit in the association and sends, via the communication channel, subscriber session data for the subscriber sessions anchored by the subscriber management service unit.
