摘要： A line card for use in a router or packet switch is disclosed. A problem with conventional routers or packet switches is that they can take over a second to fully react to a network state update from another router or packet switch. Such network state packets are used in dynamic routing protocols intended to route packets around a failed or overloaded router. In operating in according with dynamic routing protocols, conventional routers or packet switches react to such network state packets by updating the routing tables used by the line cards to send packets, or data extracted from packets, to the egress port (often on a different line card in the router or network switch) appropriate for the destination address found in the packet. Any packets which arrive between the network state packet's arrival and the completion of the ensuing routing table update on the line cards, can be misrouted—which can cause them to be delayed or dropped by the network. The described embodiments address this problem by operating the line card to react to a network state update packet by miming a restricted routing algorithm to provide interim routes whilst a conventional comprehensive routing algorithm runs in parallel to provide a comprehensive set of routes. In this way, a faster, if less thorough, reaction to the arrival of a network state update packet is provided, which reduces the risk of packets being misrouted whilst the network converges. The technique has application to any packet networks, but is especially useful in Internet Protocol packet networks or Multi-Protocol Label Switching networks.

摘要： Some embodiments provide a queue management system that efficiently and dynamically manages multiple queues that process traffic to and from multiple virtual machines (VMs) executing on a host. This system manages the queues by (1) breaking up the queues into different priority pools with the higher priority pools reserved for particular types of traffic or VM (e.g., traffic for VMs that need low latency), (2) dynamically adjusting the number of queues in each pool (i.e., dynamically adjusting the size of the pools), (3) dynamically reassigning a VM to a new queue based on one or more optimization criteria (e.g., criteria relating to the underutilization or overutilization of the queue).

摘要： Base modules are provided over a backplane network for high availability control of industrial processes or machines. The base modules may include, for example, an I/O base module, which may control the industrial processes or machines and which may releasably receive an I/O function card, an adapter base module, which may communicate with an industrial controller over a separate control network, and a bus expansion base module, which may provide coupling to another bank of base modules. The base modules may be arranged side-by-side via electrical and mechanical connections. Logic of the I/O base module may detect the presence or absence of the I/O function card to allow coupling or bypassing of the I/O function card with respect to the backplane network.

摘要： A packet processing method includes receiving a forwarding decision made for an input packet; and creating a packet processing list of the input packet according to the forwarding decision. When the forwarding decision indicates that the input packet is required to undergo first packet processing operations, each including a common processing operation and an individual processing operation, to generate first output packets forwarded via first egress ports, respectively, first information indicative of the first egress ports is recorded in an egress port field of a first session of the packet processing list; second information indicative of the common processing operation shared by all of the first packet processing operations is recorded in a common processing field of the first session; and third information indicative of individual processing operations of the first packet processing operations is recorded in an individual processing field of the first session.

摘要： Described herein are techniques for preventing MAC address spoofs in a virtualization cluster. When a virtual switch first sees a new MAC address on a port designated as being a secure port, the packet is redirected to a virtual supervisor agent used to manage the distributed virtual switch. Assuming the MAC may be bound to the secure port, the supervisor agent broadcasts a message to both the virtual switch that redirected the packet and to virtual switches on other virtualization servers within the cluster.

摘要： Embodiments described herein use APIs on network devices in a SDN enabled network to monitor the network traffic flowing through the network devices and determine an identity of the client initiating the network traffic. Specifically, the APIs provide a user application with user credentials, IP addresses, MAC addresses, and other identifying information mined from the network flows. Once the identity is found, the application may identify the client's current geographic location. The network devices may continue to monitor the network devices to identify any movement events associated with the client. In response to a movement event, the application may reallocate resources proximate to the new geographic location of the client.
摘要翻译：本文描述的实施例使用在启用SDN的网络中的网络设备上的API来监视流经网络设备的网络流量并确定启动网络流量的客户端的身份。具体来说，API为用户应用提供从网络流中挖掘的用户凭证，IP地址，MAC地址以及其他识别信息。一旦找到该身份，应用程序可能会识别客户当前的地理位置。网络设备可以继续监视网络设备以识别与客户端相关联的任何移动事件。响应于移动事件，应用可以重新分配靠近客户端的新地理位置的资源。
