摘要： Techniques for performing flow-specific failure detection in SDN networks are provided. In one embodiment, a computer system (e.g., an SDN controller) can determine a flow to be monitored in a network. The computer system can then transmit first and second messages to first and second network devices in the network respectively, where the first network device is an upstream device in the flow, where the second network device is a downstream device in the flow, and where the first and second messages instruct the first and second network devices to collect local data rate information for the flow.

摘要： A GTP correlation cluster (GCC) (120) can automatically program a network element to forward copies of packets originating from a mobile device and having a shared attribute to the same analytic server, regardless of the regions into which the mobile device moves. The GCC can monitor attributes of copies of control packets that the network element (118) receives. In response to detecting a changed attribute within a control packet originating from a mobile device, the GCC can update a session map specific to that mobile device in order to cause packets having that changed attribute to be forwarded to the same port to which packets having the former attribute were being forwarded prior to the change. As a result, the network element can ensure that packets belonging to a particular session still are forwarded to the same analytic server (130A, 130B, 130N) even if the mobile device has moved to a different region.
摘要翻译：无论移动设备移动的区域如何，GTP关联群集（GCC）（120）都可以自动编程网络元件，将来自移动设备的分组的副本转发给相同的分析服务器。 GCC可以监视网元（118）接收的控制分组的副本的属性。响应于检测到来自移动设备的控制分组中的改变的属性，GCC可以更新该移动设备特有的会话映射，以便使具有该改变的属性的分组被转发到具有以前的属性在更改之前被转发。结果，即使移动设备已经移动到不同的区域，网络元件可以确保属于特定会话的分组仍然被转发到相同的分析服务器（130A，130B，130N）。

摘要： One embodiment of the present invention provides a switch (600). The switch includes an inter-switch multicast module (630) and an edge multicast module (640). The inter-switch multicast module identifies for a first replication of a multicast packet an egress inter-switch port in a multicast tree rooted at the switch. The multicast tree is identified by an identifier of the switch. The edge multicast module identifies an egress edge port for a second replication of the multicast packet based on a multicast group identifier. The multicast group identifier is local within the switch.

摘要： A network device may execute a process (e.g., a software keepalive process (SKAP)) that schedules the transmission of keepalive messages or packets. The network device maintains a database of keepalive network sessions storing information that is used for scheduling the transmission of the keepalive messages or packets for the keepalive network sessions. The database may be read and a next transmission time and session frequency for one or more keepalive sessions may be determined. The one or more keepalive sessions may then be placed in appropriate banks within a timer queue based on the determined next transmission time and session frequency. Each bank is associated with a time period from the current time. The keepalive sessions having sooner next transmission times are placed in higher priority banks. The scheduler may allow for real-time scheduling of the one or more keepalive sessions.

摘要： A network device may execute a process (e.g., a software keepalive process (SKAP)) that enables the network device to continue to send keepalive messages or packets without interruption even during events such as a network operating system failover/switchover for the purpose of high availability or an in-place system upgrade. The network device maintains a database of keepalive network sessions storing information that is used to schedule and send keepalive messages or packets for the keepalive network sessions. The database may be shared between network operating subsystems and programs executed by the network device. The database may be updated by a network operating subsystem and the information may then be used by the SKAP to schedule and send out keepalive messages or packets for the keepalive network sessions. For example, a virtual machine may store information for a keepalive network session in the database, which is used by SKAP to schedule transmission of keepalive packets for that keepalive network session.

摘要： One embodiment of the present invention provides a switching system. The switching system includes a plurality of line cards, each of which includes one or more ports, a processor, one or more switch fabric cards for facilitating switching among the line cards, and a memory storing instructions for facilitating efficient hot-swapping. During operation, the switching system identifies a hot-swapping event of a first switch fabric card based on a data structure indicating the one or more switch fabric cards. The hot-swapping event indicates insertion or removal of the first switch fabric card while the switching system remains in an operational state. The switching system then determines an event type associated with the hot-swapping event and manages the first switch fabric card based on the determined event type.
