摘要： In general, techniques are described for decentralizing handling of subscriber sessions within a gateway device of a mobile network. A mobile network gateway comprises a data plane having a plurality of forwarding components to receive session requests from a mobile service provider network in which the mobile network gateway resides. A control plane comprises a plurality of distributed subscriber management service units coupled by a switch fabric to the data plane. Each of the subscriber management service units serve as anchors for communication sessions for mobile devices that are accessing one or more packet data network by the mobile service provider network. A request delegation module within each of the forwarding components directs the session requests to the subscriber management service units unit to provide management services for the sessions requested by the mobile device.

摘要： A device includes one or more network interfaces to receive layer two (L2) communications from an L2 network having a plurality of L2 devices; and a control unit to forward the L2 communications in accordance with forwarding information defining a plurality of flooding next hops. Each of the flooding next hops stored by the control unit specifies a set of the L2 devices within the L2 network to which to forward L2 communications in accordance with a plurality of trees, where each of the trees has a different one of the plurality of L2 devices as a root node. The control unit of the device computes a corresponding one of flooding next hops for each of the trees using only a subset of the trees without computing all of the trees having all of the different L2 network devices as root nodes.

摘要： 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.

摘要： In general, techniques are described for selectively applying and reusing filters stored in a router. In one example, a method includes receiving a network access request from a first user. The method also includes selecting a candidate rule group associated with the packet flow, wherein the candidate rule group comprises one or more currently deployed rules of an existing rule group on the computing device that are currently installed within a forwarding plane and are being applied by the forwarding plane to network traffic associated with a second user. The method also includes installing a new rule group comprising the one or more currently deployed rules of the existing rule group and one or more new rules associated with the first user and not currently installed within a forwarding plane. The method also includes applying each rule of the new rule group to network traffic associated with the first user.

摘要： Methods, apparatus, and products for routing frames in a shortest path computer network for a multi-homed legacy bridge, wherein the network includes a plurality of bridges. At least two of the plurality of bridges operate as edge bridges through which the frames ingress and egress the network. A first edge bridge identifies a legacy bridge nickname for a legacy bridge connected to the network through the first edge bridge and a second edge bridge using active-active link aggregation. The first bridge receives a frame from the legacy bridge and determines, in dependence upon the frame's destination node address, an egress bridge nickname for a third bridge through which a destination node connects to the network. The first bridge then adds the legacy bridge nickname and the egress bridge nickname to the frame and routes the frame to the third bridge in dependence upon the egress bridge nickname.

摘要： In general, this disclosure describes techniques for applying, with a network device, subscriber-specific packet processing using an internal processing path that includes service objects that are commonly applied to multiple packet flows associated with multiple subscribers. In one example, a network device control plane creates subscriber records that include, for respective subscribers, one or more variable values that specify service objects as well as an identifier for a packet processing template. A forwarding plane of the network device receives and maps subscriber packets to an associated subscriber record and then processes the packet by executing the packet processing template specified by the subscriber record. When the forwarding plane reaches a variable while executing the specified packet processing template, the forwarding plane reads the associated variable value from the subscriber record to identify and then apply the subscriber-specific service object specified by the variable.

摘要： Techniques are described for performing inline NAT functions in a forwarding element of a mobile gateway router or other device in which subscriber sessions of a mobile access network are distributed across a plurality of session management cards. The session management cards pre-allocate a public network address and port range for subscribers at the time a network connection is established in response to connection request prior to receiving any data traffic associated with the subscriber. NAT profiles are programmed into hardware forwarding elements of the mobile gateway router for inline NAT when routing subscriber traffic for the mobile access network.
