Abstract: Disclosed is a method for continuous in-line monitoring of data-centric traffic to guarantee application performance. The method includes, in each switch of a plurality of switches in a network fabric, grouping all packets entering each respective switch of the plurality of switches based on either 5-tuple applications or EPG based applications, collecting performance statistics at every hop in the network fabric across all flows in-line in a flow table maintained in each respective switch and periodically exporting the performance statistics to analysis module.

Abstract: Embodiments described herein achieve proxy FHRP for anycast routing services through the coordination of L2MP edge switches to allow load balancing for the use of routing services. Such embodiments may avoid duplicity and coordinate control planes between the edge switches to present a proxy interface to the rest of the network for the routing services. As such, multipathing and load-balancing for efficient use of crucial services may be provided for client nodes inside the network.

Abstract translation: 本文描述的实施例通过协调L2MP边缘交换机来实现用于任播路由服务的代理FHRP，以允许对路由服务的使用的负载平衡。 这样的实施例可以避免边缘交换机之间的重复和协调控制平面，以向路由服务的网络的其余部分呈现代理接口。 因此，可以为网络内的客户机节点提供用于有效使用关键业务的多路径和负载平衡。

Abstract: Disclosed are systems, methods, and computer-readable storage media for minimizing the number of entries in network access control lists (ACLs). In some embodiments of the present technology a networking device can receive, from a first computing device, a first data transmission intended for a second computing device, the first data transmission including first transmission data. The networking device can normalize at least a subset of the first transmission data based on a predetermined normalization algorithm, yielding a first normalized data set for the first data transmission. Subsequently, the networking device can identify a first access control list entry from a set of access control list entries based on the first normalized data set, the first access control list entry identifying a first action, and implement the first action in relation to the first data transmission.

Abstract: Aspects of the embodiments include receiving a packet at a network element of a packet-switched network; identifying a presence of a shared service destination address in a header of the packet; identifying a shared service destination address for the packet based, at least in part, on a destination internet protocol (IP) address stored in a forward information base; and forwarding the packet to the shared service destination address.
