摘要:
A distribution and scheduling system for advertisements that targets ads to users and maximizes service-provider revenue without having full knowledge of user-profile information. Each user device stores a user profile and is pre-loaded with a set of ads that could possibly be shown during a timeslot. Each user device selects and displays an ad based on the user profile but does not identify the selected ad to the service provider. Instead, the user devices provide perturbed user-profile information in the form of Boolean vectors, which the service provider uses in conjunction with a guaranteed-approximation online algorithm to estimate the number of users that saw a particular ad. Thus, the service provider can charge advertisers for the number of times their ads are viewed, without knowing the users' profiles or which ads were viewed by individual users, and users can view the targeted ads while maintaining privacy from the service provider.

Various embodiments provide a method and apparatus of providing a distributed network file system in a cloud network that provides performance guarantees in cloud storage that are independent of the accessed files and the access locations. A client's file system is provisioned using a file placement strategy that is based on client's access locations and determined maximum access bandwidths and does not require knowledge of file access patterns.

In one embodiment, a scheme for the display of targeted and personalized advertisements in a packet-based media-delivery system, such as an Internet Protocol Television (IPTV) service. An Internet keyword-based advertisement-bidding model is used to place the most-appropriate IPTV advertisements for viewers depending on their interests as determined through the users' Internet activities, while maximizing advertising revenue for the IPTV service provider. One method for scheduling an advertisement for rendering in one or more time slots in packet-based media programming comprises: (a) obtaining at least one keyword from one or more Internet sessions corresponding to at least one user; (b) receiving a plurality of bid amounts corresponding to a plurality of available advertisements for the one or more time slots; and (c) scheduling, based on the at least one keyword and at least one of the bid amounts, the advertisement to be rendered to the at least one user in the one or more time slots.

A method and system for scheduling tasks is provided. A plurality of lower bound completion times is determined, using one or more computer processors and memory, for each of a plurality of jobs, each of the plurality of jobs including a respective subset plurality of tasks. A task schedule is determined for each of the plurality of processors based on the lower bound completion times.

Example methods include monitoring Internet traffic for a user, analyzing content of the Internet traffic, correlating the analyzed content with a simplified classifier set, ranking each correlated simplified classifier in the simplified classifier set, and storing the ranked simplified classifiers in a user interest profile for the user. Customer premise equipment may include a residential gateway, such as a wireless router, and user equipment such as a personal computer. Example systems may be configured from customer premise equipment or Internet service providers to generate user interest profiles in accordance with example methods.

The present disclosure generally discloses packet processing offload support capabilities for supporting packet processing offload. The packet processing offload support capabilities may be configured to support general and flexible packet processing offload at an end host by leveraging a processing device (e.g., a smart network interface card (sNIC) or other suitable processing device) added to the end host to support offloading of various packet processing functions from the hypervisor of the end host to the processing device added to the end host. The packet processing offload support capabilities may be configured to support packet processing offload by including, within the end host, a virtualization switch and a packet processing offload agent which may be configured to cooperate to transparently offload at least a portion of the packet processing functions of the end host from the hypervisor of the end host to an sNIC of the end host while keeping the existing management plane and control plane interfaces of the datacenter unmodified.
摘要:
A capability is provided for providing transparent cloud computing with a virtualized network infrastructure. A method for enabling use of a resource of a data center as an extension of a customer network includes receiving, at a forwarding element (FE), a packet intended for a virtual machine hosted at an edge domain of the data center, determining a VLAN ID of the VLAN for the customer network in the edge domain, updating the packet to include the VLAN ID of the VLAN for the customer network in the edge domain, and propagating the updated packet from the FE toward virtual machine. The edge domain supports a plurality of VLANs for a respective plurality of customer networks. The packet includes an identifier of the customer network and a MAC address of the virtual machine. The VLAN ID of the VLAN for the customer network in the edge domain is determined using the identifier of the customer network and the MAC address of the virtual machine. The FE may be associated with the edge domain at which the virtual machine is hosted, an edge domain of the data center that is different than the edge domain at which the virtual machine is hosted, or the customer network. Depending on the location of the FE at which the packet is received, additional processing may be provided as needed.

A capability is provided for allocating cloud and network resources in a distributed cloud system including a plurality of data centers. A request for resources is received. The request for resources includes a request for cloud resources and an indication of an amount of cloud resources requested. The request for resources also may include a request for network resources or one or more constraints. A set of feasible resource mappings is determined based on the request for resources and information associated with the distributed cloud system. A resource mapping to use for the request for resources is selected from the set of feasible resource mappings. The selected resource mapping includes a mapping of the requested cloud resources to cloud resources of one or more of the data centers and an identification of network resources configured to support communications for the cloud resources of the one or more data centers.

The present disclosure generally discloses a data plane services support mechanism. The data plane services support mechanism may be configured to provide a data plane service for an application. The data plane services support mechanism may be configured to instantiate a virtual resource for the data plane service to be provided for the application, configure the data plane service on the virtual resource, and configure flow connectivity for the data plane service to support delivery of application traffic of the application to the data plane service. The data plane services support mechanism may be configured to support automatic scalability. The data plane services support mechanism may be configured to support improved communication of application traffic associated with providing the data plane service for the application. The improved communication of application traffic may be provided based on configuration of a virtual switch to support a network interface card (NIC) offloading capability.
