The method further includes, receiving a particular packet in the particular one of the packet flows, determining whether one or more of the conditions for routing the particular packet to the particular one of the applications are met, and routing or not routing the particular packet to the particular one of the applications based on the determination. | 01-03-2013 |
20130055091 | Graph-Based Virtual Data Center Requests - Graph-based virtual data center requests are described. In some implementations, a method includes displaying a graph having graphical elements representing network resources. A user can select one of the graphical elements and provide input specifying requirements for a network resource corresponding to the selected graphical element. A virtual data center request can be generated based on the graph and the specified requirements. The virtual data center request can be transmitted to a data center device for processing. In some implementations, the virtual data center request can be an extensible markup language (XML) representation of the graph that includes the specified service requirements. In some implementations, a data center server can receive a graph-based virtual data center request and allocate data center resources based on the virtual data center request. | 02-28-2013 |
20130074181 | Auto Migration of Services Within a Virtual Data Center - Techniques are provided herein for detecting that virtual data center services provided to one of at least two customers are being subjected to an attack, wherein the virtual data center services are provided to the least two customers using a same first set of physical servers via a first network element such as a physical access switch, and responsive to detecting that virtual data center services provided to the one of the at least two customers are being subjected to an attack (e.g., a virus or denial of service attack), the technique causes the virtual data center services provided to the one of the at least two customers to be migrated to, e.g., instantiated on, a second set of physical servers that is not accessible via the first network element. | 03-21-2013 |
20150085665 | SYSTEM AND METHOD FOR IMPROVING TCP PERFORMANCE IN VIRTUALIZED ENVIRONMENTS - Example embodiments described herein provide systems and methods for transmitting data packets between a protocol sender and a protocol receiver in a cloud environment, having either the protocol sender or the protocol receiver residing within a virtualized host. A protocol acceleration module may observe the data packets transmitted along the data path between the protocol sender and the protocol receiver using protocol stack configuration information of the protocol sender. The protocol acceleration module may override the protocol stack configuration information with policy-based protocol stack configuration information such that data packets transmitted from the protocol acceleration module to the protocol receiver use the policy-based protocol stack configuration information. For various embodiments, the protocol stack configuration information of the protocol sender is not modified. | 03-26-2015 |
