Apparatuses and methods are provided in which a CE protocol communication session is established, at a first provider edge network device (PE), for customer equipment device (CE) multi-homed to the first PE and one or more second PEs. The first PE is an owner of the CE protocol communication session. The first PE signals to the one or more second PEs an ownership message indicating that the first PE is the owner of the CE protocol communication session. The ownership message includes parameters that enable one or more second PEs to install in their respective forwarding tables a redirect policy to instruct the respective PE to forward packets of this session to the first PE via an overlay segment. The first PE receives the packets of the session via the overlay segment based on the ownership message.

A system and method for bandwidth management by controlling the bit rate of a signal stream in real time according to available link bandwidth. Applications include multiple-channel video data streams over a limited-bandwidth link such as a Digital Subscriber Line. A video signal is transrated at the head end to multiple streams having different bit rates, by a multirating device which sends the multiple streams over a network, along with metadata containing information about the data structure and parameters of the streams. At the network access edge, a demultirating device uses the metadata to select the stream with the highest video quality whose bit rate does not exceed the available bandwidth of the end-user's access link. This scheme provides multiple unicast signals to different end-users in place of a single multicast signal, supports multiple high-definition channels over a limited bandwidth link, and is compatible with standard encryption methods.

Systems and methods use a fiber-based network to provide both network access services such as Internet, television, phone, and wide area networking services as well as distributed data processing services. Distributed computing nodes are provided in broadband gateways at homes and other premises in a fiber-based network to realize a distributed data center architecture. In a specific example, a provider deploys a number of broadband gateways in the homes of homeowners who agree to pay for network access (e.g., Internet, phone, television, etc.) that is received over a fiber-based (preferably point-to-point) network at the broadband gateways in the homes. Those broadband gateways also separately provide distributed workload processing. Providing both network access and distributed workload processing makes the deployment and use of the fiber-based network more economically and technically feasible.

System, method, and computer program product to perform an operation, comprising establishing a connection between a primary intermediate branch director (IBD) in a first branch of an enterprise network and a first proxy IBD in a second branch of the enterprise network, receiving, at the primary IBD, network topology information for each of a plurality of intermediate branch clients (IBCs) in the second branch of the enterprise network, and issuing, by the primary IBD to the first proxy IBD, a command to remotely configure at least one IBC of the plurality of IBCs in the second branch of the enterprise network.

The invention relates to a method of a communication node communicating in a network comprising a plurality of nodes, said nodes belonging to at least one virtual network, wherein the method comprises the communication node identifying whether a first data packet belongs to said virtual network based on at least one of:—a cryptographic key used for the data packet;—a cryptographic key identifier present in the first data packet;—a Personal Area Network identifier present in the first data packet; or the combination of a cryptographic key and a sender IP address used for the first data packet.

Disclosed are a bearer side network system, a fixed-mobile coexistence and convergence system and deployment methods therefor. The bearer side network system includes a fixed-mobile bearer Internet protocol (IP) metropolitan area network for achieving a uniform bearer of mobile communication and fixed communication, and a mobile communication core network user plane apparatus sunk to an aggregation layer of the fixed-mobile bearer IP metropolitan area network; and the mobile communication core network user plane apparatus is in a communication connection with the fixed-mobile bearer IP metropolitan area network.

In general, techniques are described for dynamically programming a cloud-based service exchange to enable connections from an enterprise buyer in one metropolitan area to connect to a cloud exchange in another metropolitan area. For example, a network data center includes a programmable network platform to receive an indication of a network service provider (NSP) configured to transport traffic to a customer in a second metropolitan area; provision a virtual circuit from a customer-facing port of a cloud-based services exchange point of the second metropolitan area to the NSP; receive a service request that specifies one or more cloud services provided by one or more cloud service provider networks of the first metropolitan area operated by the respective cloud service providers; and configure access to the one or more cloud services provided by one or more cloud service provider networks via the virtual circuit.
