Abstract: The present invention addresses the need for improved virtualized cloud infrastructure policy implementation and management in order allow real-time monitoring and optimization of virtualized resources. It provides systems and methods for real-time cloud infrastructure policy implementation and management that include a plurality of host devices, a plurality of real-time probe agents associated with the plurality of host devices operating on each of the plurality of host devices, and a policy engine communicatively coupled to the plurality of host devices and containing a policy associated with an application program deployed in at least one of the plurality of host devices. The policy engine is programmed to monitor in real time changes in deployment of the application program across the plurality of host devices and to push the policy to the real-time probe agent operating on each host device on which the application program is deployed.

Abstract: An assessment environment is provided to generate real-time or nearly real-time events and/or alarms based at least on operational state of a host device. An agent module executing in the host device can monitor some or all of the performance metrics that are available in the host device and can analyze the monitored information in order to generate operational information and/or intelligence associated with an operational state of the host device and/or a computing component (e.g., an application, a virtual machine, or a container) associated therewith. The monitoring and analysis can be performed locally at the host device in real-time or nearly real-time. Analysis of the monitored information can be utilized to update first control information indicative of occurrence of an event and/or second control information indicative of presence or absence of an alarm condition. The control information can be sent to a remote device.

Abstract: In various example embodiments, a system and method are presented for a bandwidth (BW) management system. The BW management system includes a BW manager module to manage bandwidth of a collection of flows by traffic classes using bandwidth limits assigned to the traffic classes arranged in a hierarchical bandwidth tree (HBT). The BW management system includes a quality of service (QOS) manager module to manage bandwidth for leaf traffic subclasses in the HBT based on application priority classifications. The bandwidth management system including a window manager (WM) module to manage bandwidth for individual flows in the collection of flows using a sliding window protocol to control the rate at which the first host transmits data packets to the second host. The QOS manager module is in communication with the WM module and the BW manager module while the bandwidth management system is actively managing the bandwidth of the collection of flows.

Abstract: In various example embodiments, a system and method are presented for a bandwidth (BW) management system. The BW management system accepts, on behalf of a receiving host, data packets for a first individual flow at a flow rate sent by a sending host. The bandwidth management system manages bandwidth by traffic classes representing collections of flows associated with nodes in a hierarchical bandwidth tree (HBT). The first individual flow is included within the collection of individual flows associated with one or more of the traffic classes. The BW management system controls the rate at which the sending host is transmitting the data packets for the first individual flow using a sliding window protocol by managing the bandwidth utilization of the nodes to conform to bandwidth limits assigned to the nodes. The BW management system receives the data packets for the first individual flow at an adjusted flow rate based on the sliding window protocol.
