In response to the received signaling, one or more files are transmitted to the client device via the packet-based telecommunication network, each of the one or more files being in a format compatible with a media player on the client device, the one or more files comprising (i) an identification of one or more of the resources of the content distribution network available to facilitate streaming of one or more segments of the stored video content to the client device, the identification being dependent at least in part on a relationship between a geographic location of the client device and geographic locations of the resources of the content distribution network, and (ii) an identification of an advertising server, the identification of the advertising server being dependent at least in part on a relationship between the geographic location of the client device and a geographic location of the advertising server, wherein the one or more files, when processed by the client device, cause the client device to communicate with the identified one or more resources of the content distribution network and the advertising server to cause the one or more segments of the stored video to be streamed to the client device by the identified one or more resources of the content distribution network and cause one or more advertisements to be streamed from the advertising server to the client device.

For allocating resources in a mesh communications network for setting up a data stream transmission from a talker device to a listener device via at least one node device, data paths being defined throughout the mesh communications network following a link-state routing protocol, each node device performs receiving, obtaining, determining, and checking. And when there are enough said resources, temporarily reserving and propagating. And when receiving for said data stream transmission a stream reservation response representative of a positive acknowledgement to said stream reservation request, effectively allocating and propagating.

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.

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.

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.

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.

Systems, methods, and computer programs are presented for managing network traffic. A network switch includes a switch fabric and a resource coherency and analytics engine (RCAE) coupled to the switch fabric. The RCAE includes one or more virtualizable resource groups (VRGs) for managing network traffic flow across a plurality of network switches on the network. Further, the RCAE is operable to add network entities to each VRG, add flows to each VRG, and add other VRGs to each VRG. A virtualizable resource control list (VRCL), associated with each VRG, identifies which network entities in the VRG can communicate with each other, which network entities in the VRG can communicate with network entities in other VRGs, and a guaranteed bandwidth for the VRG associated with the VRCL. Furthermore, the RCAE is operable to exchange messages with other RCAEs in other network switches to implement traffic policies defined by each VRCL.
