In a method of providing granular quality of service in a hybrid content distribution network of classical distribution in a network via client-server plus very distributed mechanisms operating peer to peer inside the network, content is replicated in a large number of endpoint nodes, some of which are CPEs of broadband subscribers, and backed by a few storage servers to ensure content availability. Traffic is delivered by a mixture of P4P for choice of seeds and selection of good neighborhoods for quick content download. The ISP uses the unsold physical capacity of the link for CDN service and other underutilized resources, and enforces seeding at many nodes including broadband subscriber CPEs. By having a large farm of nano-datacenters distributed across the network, including the premises of broadband customers, the ISP can maintain and run a CDN. A tracker determines where to seed the content, depending on the number of broadband subscribers requesting the content, the geographical distribution of requested content, and the Service Level Agreement between content providers and the ISP. The tracker can seed a sufficient number of nodes to ensure redundancy.

In a method for managing servers in a data center, an peripheral BMC list of each candidate BMC is updated, when any candidate BMC receives a data packet from an peripheral BMC. A master BMC is determined from all of the candidate BMCs, and the master BMC sends starting instructions to each peripheral BMC at a specified time interval, according to a preset start sequence. Power supply devices corresponding to the master BMC and all the candidate BMCs are powered on after all of the power supply devices corresponding to the peripheral BMCs have been powered on, and all of the servers in the data center are started in this manner

Systems and methods provide personal channels from a network-capable user terminal. A first user terminal may receive a request from a second user terminal for access to a personal channel created by a user and stored on the first user terminal in association with media content. In response to the request, the first user terminal may access the media content associated with the requested personal channel and provide the media content to the first user terminal over the network. A data center accessible by both the first and second user terminals may facilitate the access to the personal channel by storing information associated with the personal channel, including terminal identifiers and metadata, and providing a searchable catalog interface to identify personal channels to view.

Some embodiments establish for an entity a virtual network over several public clouds of several public cloud providers and/or in several regions. In some embodiments, the virtual network is an overlay network that spans across several public clouds to interconnect one or more private networks (e.g., networks within branches, divisions, departments of the entity or their associated datacenters), mobile users, and SaaS (Software as a Service) provider machines, and other web applications of the entity. The virtual network in some embodiments can be configured to optimize the routing of the entity's data messages to their destinations for best end-to-end performance, reliability and security, while trying to minimize the routing of this traffic through the Internet. Also, the virtual network in some embodiments can be configured to optimize the layer 4 processing of the data message flows passing through the network.

An identity management tool provides identity management across multiple domains, providing a single access point not only for information for runtime, network, and service layer information, but also for systems such as business support systems (BSS), operational support systems (OSS), and third party systems. The identity management tool creates a unified user profile that maps customer identities across the various domains, and presents the information in a virtual directory wherein the information appears to come from a single source, creating a central data hub for the various systems. This aggregation provides for the same experience and service across various access networks and using various channels. Such an architecture allows billing and service information to be shared with subscription and customer information, even though the data is substantially unrelated data from disparate data sources, without the need to combine schemas or aggregate the data into a single data store.

The system and method described herein may include a configuration management database that describes every known service endpoint in a network datacenter to represent a steady state for the datacenter. One or more listeners may then observe traffic in the datacenter in real-time to detect network conversations initiating new activity in the datacenter, which may be correlated, in real-time, with the information in the configuration management database representing the steady state for the datacenter. Thus, in response to the new activity failing to correlate with the known service endpoints, a real-time security alert may be generated to indicate that any network conversations initiating such activity fall out-of-scope from the steady state for the information technology datacenter.

The data center flow control method and the data center flow control system based on the openflow has a good application prospect.

An automated identification, weight measurement and data reporting system that allows users to have their weight measured at a remote location and sent electronically to a data center. The invention can use biometric identification technology to confirm the identity of the user at the time of the measurement of the user's weight. The user's body weight may be measured via an electronic scale connected to the biometric identification device. The measurement data is then sent via a network (such as the Internet) to a central database. This secure weight measurement data is then used to offer incentives to individuals to lose weight. The more weight an individual loses, the larger the earned incentives. The invention also includes programs to measure health functions and to provide incentives to improve their health including body fat reduction, quitting smoking, reducing their blood pressure, or other health function.

Some embodiments provide a novel method for deploying different virtual networks over several public cloud datacenters for different entities. For each entity, the method (1) identifies a set of public cloud datacenters of one or more public cloud providers to connect a set of machines of the entity, (2) deploys managed forwarding nodes (MFNs) for the entity in the identified set of public cloud datacenters, and then (3) configures the MFNs to implement a virtual network that connects the entity's set of machines across its identified set of public cloud datacenters. In some embodiments, the method identifies the set of public cloud datacenters for an entity by receiving input from the entity's network administrator. In some embodiments, this input specifies the public cloud providers to use and/or the public cloud regions in which the virtual network should be defined. Conjunctively, or alternatively, this input in some embodiments specifies actual public cloud datacenters to use.

Gang migration refers to the simultaneous live migration of multiple Virtual Machines (VMs) from one set of physical machines to another in response to events such as load spikes and imminent failures. Gang migration generates a large volume of network traffic and can overload the core network links and switches in a datacenter. In this paper, we present an approach to reduce the network overhead of gang migration using global deduplication (GMGD). GMGD identifies and eliminates the retransmission of duplicate memory pages among VMs running on multiple physical machines in the cluster. The design, implementation and evaluation of a GMGD prototype is described using QEMU/KVM VMs. Evaluations on a 30-node Gigabit Ethernet cluster having 10 GigE core links shows that GMGD can reduce the network traffic on core links by up to 65% and the total migration time of VMs by up to 42% when compared to the default migration technique in QEMU/KVM. Furthermore, GMGD has a smaller adverse performance impact on network-bound applications.
