A method of dynamically adding a communication service function to a communication session comprises receiving a communication during a communication session on an active connection, detecting a communication service trigger in the communication, determining a second communication service function based on the communication service trigger, sending a message to a network function virtualization (NFV) catalog, receiving a response from the NFV catalog, providing the routing information to a software defined network (SDN) controller, routing the communication from the first communication service function to the second communication service function, processing the communication with the second communication service function, and routing the communication to an output. The message to the NFV server can include an identity of the second communication service function. The SDN controller can set the session routing protocol to include the second communication service function in a communication flow for the communication session.

MPLS segment routing is disclosed. In one embodiment, a first core router generates a first data structure that maps first portcodes to respective identities of first neighbor routers or respective first links, wherein the first portcodes identify respective first ports of the first core router, and wherein the first ports are coupled to the first neighbor routers, respectively, via the first links, respectively. The first core router generates and transmits a first link-state packet, wherein the first link-state packet comprises an identity of the first core router and the first data structure.

Methods, systems and computer readable media for mobile endpoint network interface selection using merged policies.

In general, this disclosure describes a high-level forwarding path description language (FPDL) for describing internal forwarding paths within a network device. The FPDL enables developers to create a template that describes a section of an internal forwarding path within the forwarding plane of a network device. The FPDL provides syntactical elements for specifying the allocation of forwarding path structures as well as enabling the run-time construction of internal forwarding paths to interconnect the forwarding path structures in a manner specific to packet, packet flow, and/or interface properties, for example. In conjunction with late binding techniques, whereby the control plane of the network device provides arguments to template parameters that drive allocation by the packet forwarding engines of forwarding path structures specified by the FPDL, the techniques provide control plane processes a unified interface with which to manage the operation of the packet forwarding engines.

Methods, systems, and computer programs are presented for a switching server. One switching server includes a server, a switch module coupled to the server, and a switch controller coupled to the server and to the switch module. The server includes a processor executing an operating system that includes a network driver, and the network driver includes a first network device operating system (ndOS) program. Further, the switch module includes a switch fabric and input/output ports. The switch controller includes a processor and non-volatile storage, where the processor is configured to execute a second ndOS program. The first and second ndOS programs implement a global networking policy for a plurality of devices executing ndOS programs, the global networking policy including a definition for switching incoming packets through the plurality of devices executing the ndOS programs.

The invention provides, in some aspects, a digital commerce system that includes a first digital data device, a second digital data device and a third digital data device, each of which is connected to a network that provides at least intermittent communications coupling between the second digital data device and each of the first and second digital data devices. Redirection logic executing on at least the second digital data device effects storage on the third digital data device of a digital media object downloaded from the first digital data device to the second digital data device. The redirection logic accomplishes that in such a manner that storage of the digital media object on the third digital data device is effected before storage of that digital media object on the second digital data device—if the digital media object is stored to the second digital data device at all. In related aspects of the invention, redirection logic executing on at least the second digital data device circumvents storage of the downloaded digital media object at least until that object has been stored on the third digital data device.

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.

A data processing system with routing tables comprising an operating system for supporting processes, such that the process are associated with one or more resources and the operating system being arranged to police the accessing by processes of resources so as to inhibit a process from accessing resources with which it is not associated. Part of this system is an interface for interfacing between each process and the operating system and a memory for storing state information for at least one process. The interface may be arranged to analyze instructions from the processes to the operating system, and upon detecting an instruction to re-initialize a process cause state information corresponding to that pre-existing state information to be stored in the memory as state information for the re-initialized process and to be associated with the resource.

A method for programming route hardware in network devices. The method includes: receiving, by a network device, route updates, selecting from the route updates, a set of selected routes to be used for routing, assigning multiple timestamps to the set of selected routes, programming the set of selected routes into a software-implemented forwarding information base (FIB), segmenting the set of selected routes in the software-implemented FIB into at least a first batch of routes and a second batch of routes, programming the first batch of routes into a hardware-implemented FIB, after the programming, determining a last timestamp, where the last time stamp is the oldest timestamp of the timestamps where all routes associated with the last timestamp have been successfully programmed into the hardware-implemented FIB, and advertising all routes of the first batch that are associated with a timestamp that is no older than the last timestamp.

Methods, systems, and storage mediums that can allow for automatic re-routing of network traffic in software-defined networks. In some examples, instructions can be provided to network switches in a software-defined network to initially route network traffic along a first flow route. The instructions can further instruct the network switches to automatically re-route the network traffic along a second flow route at a later time.
