Abstract: A network device includes an internal policy engine that makes local policy decisions for packet flows and controls policies applied by service modules and forwarding components of the network device. The policy engine interacts with an external policy server to receive policies using software defined networking (SDN) protocol as if the data plane of the network device were directly exposed to the external policy server by the SDN protocol.

Abstract: Techniques are described for providing session-aware, stateful network services to subscriber packet flows. Devices within a service provider network direct subscriber packets along service chains. Each tunnel is established to direct traffic according a particular ordered set of network services for the corresponding service chain. An ingress device for the tunnels encapsulate the subscriber packets and embed opaque session cookies that each uniquely identifies a collection of packet flows of a subscriber session amongst other packet flows transported by a given service tunnel. Each service node need only identify the tunnel on which a tunnel packet was received and the session cookie embedded within the tunnel packet to uniquely associate the encapsulated subscriber packet with a subscriber session, without needing to further inspect the encapsulated subscriber packet, and to index or otherwise retrieve state and statistics required to enforce the network service the service nod is programmed to deliver.

Abstract: In general, the invention is directed to techniques for offloading mobile data traffic from a mobile core network to a broadband network. For example, as described herein, a breakout gateway forwards a service request from a mobile device and addressed to a service node. The service node designates an access point name (APN) for offload such that data traffic associated with service requests specifying the designated APN is to be offloaded to an offload network. The service node receives the service requests from the breakout gateway and, if the service request specifies the designated APN, the service node sends a request to the breakout gateway. The breakout gateway receives the request and assigns a routable PDP address to the mobile device. An offload module on the breakout gateway redirects mobile data traffic to the offload network when the source PDP address of the traffic is the previously assigned PDP address.
Abstract translation: 通常，本发明涉及将移动数据业务从移动核心网卸载到宽带网络的技术。 例如，如本文所述，分组网关从移动设备转发服务请求并寻址到服务节点。 服务节点指定用于卸载的接入点名称（APN），使得与指定指定APN的服务请求相关联的数据流量将被卸载到卸载网络。 服务节点接收来自分组网关的服务请求，如果服务请求指定了指定的APN，则服务节点向中断网关发送请求。 分组网关接收请求，并向移动设备分配可路由的PDP地址。 当流量的源PDP地址是先前分配的PDP地址时，分支网关上的卸载模块将移动数据流量重定向到卸载网络。

Abstract: Network devices, such as a router and a downstream multicast distribution device, may use multiple control channels when setting up a multicast stream for a multicast request. For example, first messages may be transmitted using a first protocol to an upstream device over a first channel, the first messages indicating when a first multicast media stream is being requested by at least one of a number of client devices. Second messages may be transmitted using a second protocol over a second channel, the second messages being transmitted on a per-client basis and each identifying a one of the client devices as requesting the first multicast media stream. By using two control channels to convey the multicast channel requests, the router may obtain visibility into the action of the subscriber and can consequently perform per-subscriber operations such as access-control, bandwidth based admission control, statistics, and QoS adjustment for multicast IPTV streams received by the subscriber.
Abstract translation: 诸如路由器和下游组播分发设备之类的网络设备在为组播请求建立组播流时可以使用多个控制信道。 例如，可以使用第一协议将第一消息通过第一信道发送到上游设备，第一消息指示何时由多个客户端设备中的至少一个请求第一多播媒体流。 可以使用第二协议在第二信道上发送第二消息，第二消息是在每个客户端的基础上发送的，并且每个将客户端设备中的一个识别为请求第一多播媒体流。 通过使用两个控制信道来传送组播信道请求，路由器可以获得对用户动作的可见性，并且因此可以执行诸如接入控制，基于带宽的接纳控制，统计和用于组播IPTV的QoS调整之类的每用户操作 用户接收的流。
