A method, system, and/or computer program product configures hierarchical cloud resources. A supervisor server receives a signal indicating a boundary of a set of hierarchical cloud resources. The boundary describes a level of resource sharing among the set of hierarchical cloud resources, which includes a set of software applications, a set of middleware that supports one or more software applications from the set of software applications, and a set of virtual mechanisms that supports one or more middleware from the set of middleware. The supervisor server receives a signal from one or more Isolation/Density (I/D) switches, which are associated with one or more software applications from the set of software applications and one or more middleware from the set of the middleware, and then configures the hierarchical cloud resources, according to the boundary of the set of hierarchical cloud resources, and according to settings of the I/D switches.

Embodiments of the present invention provide a method and a device for allocating a packet switching resource, which includes: receiving, by a management plane unit, a service transport request carrying service information, where the service information includes source node information, sink node information, quality of service QoS requirement information, and bandwidth requirement information; determining, by the management plane unit, at least one transport path according to the service information and a preset resource allocation policy, and generating a routing table entry/forwarding table entry according to the at least one transport path; and sending, by the management plane unit, the routing table entry/forwarding table entry to data plane units of packet switching devices of each transport path of the at least one transport path. According to the embodiments, transparent and controllable allocation of a network bandwidth resource is implemented, so that utilization efficiency of a network resource is improved.

A method intended to aid in the reservation of resources within a packet-switched communication network (CR) comprising a number N of relaying nodes (S1-S4). This method consists i), in determining for some at least of the N nodes (S1-S4) at least one resource reservation plan Pik defined by a plan identifier associated with a stream identifier and at least two ports, and ii) in memorizing for each of the N nodes (S1-S4) the various plans Pik relating to them.

A method is disclosed for transmitting system management requests to computer systems along a network path using a network control protocol, such as RSVP. For example, an originating node may send a single system management request along a path to a destination node using a network control protocol. Each computer system along the network path may analyze the network control protocol message to determine whether the message contains a system management request. If a system management request is found in the message, the computer system may perform the system management function identified in the request, and respond to it.

Techniques are described for reporting, by non-ingress routers for traffic engineering label switched paths (TE LSPs) and to a path computation element, actual paths taken by the TE LSPs through the network. A first network device: receives, from a second network device, an LSP path signaling message that includes a route object having a first indication of at least a sub-path of a path for TE LSP through a network, wherein the first network device is not an ingress label edge router for the TE LSP; generates, in response to the LSP path signaling message and based at least in part on the route object, an LSP path report message that includes a second indication of the at least the sub-path of the path for the TE LSP; and sends, to a path computation element, the LSP path report message to notify the PCE.

The present disclosure relates to systems, methods, electronic devices and applications for content streaming with an intermediate content buffer. In one embodiment, a method includes detecting, by a content buffer, a request for network content from a player, wherein the request is a network communication detected by the content buffer and the request for network content is directed to a server and identifying, by the content buffer, associated network content, wherein the associated network content is associated with the network content requested by the player. The method may also include pre-downloading associated network content for the player based on the identifying, wherein the content buffer requests associated network content from the server, and providing the associated network content to the player. Another embodiment is directed to a device configured to run a content buffer and provide content for a content player.

[Object] To provide a communication control device configured to efficiently secure bands of an IP network in order to transmit data streams.

[Solution] There is provided a communication control device including: a channel information acquisition unit configured to acquire, when AV streams are transmitted from a plurality of transmission apparatuses to one or more reception apparatuses on an IP network while being switched, all channel information from the transmission apparatuses to the reception apparatuses; a traffic calculation unit configured to calculate a maximum traffic generated in switching patterns of the transmission of the AV streams from the transmission apparatuses to the reception apparatuses, on the basis of the channel information acquired by the channel information acquisition unit; and a transmission band reservation unit configured to reserve a transmission band on the IP network, on the basis of the maximum traffic calculated by the traffic calculation unit.

Data flow through a network device is periodically sampled. Lower and upper bandwidth reservation limits are periodically updated from the sampled data flow. A current setting of the bandwidth reservation for the flow path associated with the data flow is compared against the range bounded by the lower and upper bandwidth reservation limits. When the current bandwidth reservation falls outside of the range, bandwidth reservation of the flow path is adjusted.

Techniques are described for specifying and constructing multi-protocol label switching (MPLS) rings. Routers may signal membership within MPLS rings and automatically establish ring-based label switch paths (LSPs) as components of the MPLS rings for packet transport within ring networks. In one example, a router includes a processor configured to establish an MPLS ring having a plurality of ring LSPs. Each of the ring LSPs is configured to transport MPLS packets around the ring network to a different one of the routers operating as an egress router for the respective ring LSP. Moreover, each of the ring LSPs comprises a bidirectional, multipoint-to-point (MP2P) LSP for which any of the routers can operate as an ingress to source packet traffic into the ring LSP for transport to the respective egress router for the ring LSP. Separate protection paths, bypass LSPs, detours or loop-free alternatives need not be signaled.
