Exemplary embodiments for enabling planned network changes such as an upgrade or downgrade of a network device are disclosed. The systems and methods provide for planned upgrades and downgrades for network devices without impacting existing network sessions, by utilizing two network devices simultaneously, and creating a redirect network session for a predetermined period of time. In so doing, all network traffic may be gradually transferred to the second network device, until the sessions processed by the first network device time out. The first network device can then be taken offline for upgrade or downgrade, without any disruption to the network service or loss of network traffic.

A server selection devices includes: an acquisition unit for acquiring, regarding each of a plurality of servers having the same content, a list of quality information corresponding to communication environment information regarding a source of request for download of the content; and a selection unit for selecting one of the plurality of servers based on the list of the quality information regarding each of the plurality of servers and a cost associated with download of the content. Thus, a destination of a content download request can be selected while giving consideration to not only quality but also cost.

Systems, apparatus and methods are disclosed which are directed to computer program products for automatically understanding and addressing the QoS adherence of a workload in a computer network. The use of pricing can be used to provide QoS adherence for any type of demand or service. The disclosed methodologies can be applied to applications, to virtual machines, to storage, and/or other types of workload, demand or service that is achieved through the use of shared resources.

Aspects of the present disclosure involve systems, methods, computer program products, and the like, for managing the distribution of content and/or communications from a telecommunications or computer network to an end user of the network. In general, the system receives a request for content from a user of the network and analyzes the request to determine an estimated geographic region and/or an access network associated with the requesting device. Based on the determined geographic region or access network, a networking device returns a specific anycast IP address from which the content may be received. In this manner, the content providing network may utilize multiple anycast IP addresses within the network to provide content to one or more end users of the network. The specific anycast IP address is provided to an end user device to obtain the requested content.

There are provided a system, a method and a computer program product for operating a cloud computing infrastructure. In one embodiment, the system and method performs allocation domain modeling and provides a cloud scheduler framework that takes as input desired optimization objectives and the workload constraints and efficiently produces a placement solution that satisfies the constraints while optimizing the objectives in a way that adjusts itself depending on the objectives. As the objectives change, e.g., due to actions from system administrators or due to changes in business policies, the system optimizes itself accordingly and still produces efficient and optimized placement solutions. The system and method constructs an Allocation Domain (AD) that is a particular facet for allocating a logical entity to a physical entity. An AD is created using: variables, functional definitions (functions of variables), and a policy specification that includes a Boolean expression (of the functional definitions).

The disclosure provides a network path determination module, a method of determining a network path, and a non-transitory storage medium which stores computer readable instruction to execute functions related to the method of determining a network path. In an aspect, the network path determination module includes not limited to: a first port; a non-transitory storage medium; and a processor coupled to the non-transitory storage medium, configured at least to: receive, through the first port, a requested generated by a detected data flow to create a forwarding entry in a network node for the data flow; retrieve a current network topology and a network status; select a network path based on the current network topology and the network status; generate a network control instruction based on the network path which has been selected; and execute the network control instruction to forward the data flow on the network path.

A system designed for increasing network communication speed for users, while lowering network congestion for content owners and ISPs. The system employs network elements including an acceleration server, clients, agents, and peers, where communication requests generated by applications are intercepted by the client on the same machine. The IP address of the server in the communication request is transmitted to the acceleration server, which provides a list of agents to use for this IP address. The communication request is sent to the agents. One or more of the agents respond with a list of peers that have previously seen some or all of the content which is the response to this request (after checking whether this data is still valid). The client then downloads the data from these peers in parts and in parallel, thereby speeding up the Web transfer, releasing congestion from the Web by fetching the information from multiple sources, and relieving traffic from Web servers by offloading the data transfers from them to nearby peers.

A system for migrating a non-tenant-aware local application to a tenant-aware cloud application environment is disclosed to migrate individual modules of the application to instances of the cloud by grouping the modules via common characteristics in partition groups. By grouping modules together by partition group before migrating the modules to cloud instances, modules that share resources can be placed in closer logical proximity to one another in the cloud, modified, or deleted to optimize performance. The information from these modules is processed to create a visualization graph representing information on the cloud. The visualization graph is preferably multilayered so it can display information from different hierarchical layers of a cloud instance.
