    Abstract: Techniques are provided for enabling tag networking. In one example, a network device (e.g., switch, router, etc.) is configured to receive a packet of a traffic flow and to analyze the traffic flow to determine the packet belongs to a particular type of traffic. The network device can then add and/or change a tag in a data field of the packet. The tag, among other things, serves as an identifier for the particular type of traffic flow. The tag is identifiable by a downstream node that is preconfigured to recognize the tag and to carry out logic in response to recognizing the tag. Advantageously, the tag functionality of the present approach provides a generalized way of adding information to packets; the information and the associated functionalities are customizable during a runtime of the network.

    Abstract: Techniques are provided for automating a common framework for network devices. In one example, a network device (e.g., switch, router, etc.) is configured to resolve the handling unknown packets automatically. The network device can detect whether or not a protocol is unknown to the network device, perform a lookup, determine if a matching protocol is available for the network device, and dynamically load an appropriate protocol handler into a memory of the network device. Advantageously, the present technology provides a mechanism for flexible on-demand push of protocol information. If a new protocol is noted on the network, the network device can look up the type of packet and can use a single platform kit to dynamically load drivers and control logic for that protocol onto the network device. Likewise, other network devices in the packet's path or in the network generally can load the drivers and control logic, as needed.

    Abstract translation: 提供了用于自动化网络设备的通用框架的技术。 在一个示例中，网络设备（例如，交换机，路由器等）被配置为自动解决处理未知分组。 网络设备可以检测网络设备的协议是否未知，执行查找，确定匹配协议是否可用于网络设备，以及将适当的协议处理程序动态加载到网络设备的存储器中。 有利地，本技术提供了一种灵活的按需推送协议信息的机制。 如果在网络上注明新的协议，则网络设备可以查找分组的类型，并且可以使用单个平台工具来动态地将该协议的驱动程序和控制逻辑加载到网络设备上。 同样，数据包路径或网络中的其他网络设备通常可以根据需要加载驱动程序和控制逻辑。

    Abstract: Techniques are disclosed for using arbitrary criteria to define events occurring within a network infrastructure, as well and techniques for detecting and responding to the occurrence of such custom events. Doing so allows a collection of networking elements (switches, routers, etc.) to perform a variety of distributed functions from within the network itself to respond to custom events. Further, because custom events are published across the network, multiple network elements can communicate and respond to the same event. Thus, unlike currently available event management systems, custom events (and responding applications) can be used to create and coordinate software defined networking within a common network infrastructure.

    Abstract: Techniques are disclosed to extend routing rules from external services. A request is received to modify a specified rule in a network element of a network. The specified rule governs disposition of a network flow specific to an application. The request is received via a communications channel configured to expose an application programming interface (API) to the application. The request is interpreted at a network abstraction layer of the network element. The request is converted into a command at a service implementation layer of the network element. The command is executed to modify the specified rule in the network element, responsive to the request.
