Abstract: In general, techniques are described for steering data traffic for a subscriber session from a network interface of a wireless access gateway to an anchoring one of a plurality of forwarding units of the wireless access gateway using a layer 2 (L2) address of the data traffic. For example, a wireless access gateway for a wireless local area network (WLAN) access network is described as having a decentralized data plane that includes multiple forwarding units for implementing subscriber sessions. Each forwarding unit may present a network interface for sending and receiving network packets and includes packet processing capabilities to enable subscriber data packet processing to perform the functionality of the wireless access gateway. The techniques enable steering data traffic for a given subscriber session to a particular one of the forwarding units of the wireless access gateway using an L2 address of the data traffic.

Abstract: In general, techniques are described for using virtual local area networks (VLANs) to facilitate packet forwarding between wireless endpoint devices attached to a wireless local area network (WLAN) access network and one or more mobile gateways providing access to packet data network services. For example, a wireless access gateway includes an upstream interface for a mobility tunnel to a mobile gateway of a mobile service provider network and a downstream interface for a WLAN access network. The wireless access gateway receives a packet from the mobile gateway by the upstream interface. The wireless access gateway determines, based at least on the mobility tunnel, a VLAN of the WLAN access network that is uniquely associated in the wireless access gateway with a combination of the APN associated with the mobility tunnel and the mobile gateway. The wireless access gateway then forwards, to a wireless endpoint device, the packet on the VLAN.

Abstract: In general, techniques are described for aggregating, within a network device, internal forwarding routes for multiple control protocols and allocating next hops for the routes among individual service units of a decentralized control plane for the network device. The techniques may also include aggregating internal forwarding routes for data protocols and allocating next hops for the routes among individual forwarding units of a decentralized data plane for the network device. In one example, a mobile gateway includes a plurality of subscriber management service units that present a uniform interface to nodes within a mobile service provider network. An allocation manager apportions a control protocol session identifier namespace into a plurality of contiguous, non-overlapping protocol session identifier ranges and allocates the ranges among the service units. The service units execute the control protocol by utilizing respective allocated ranges, which the aggregate internal forwarding routes use to identify the associated service units.
