Intelligent traffic routing may be utilized to route packets of information to one or more radio access technologies and/or cells/access points based on network and/or UE conditions. Packet routes dynamically may be adjusted based on the best radio technology, cell layer, service provider specified criteria, or the like. In an example configuration, intelligent traffic routing may be SDN based utilize a simple Internet protocol.

Intelligent traffic routing

Intelligent radio access control selecting a first cell device of a first cell layer or a second cell device of a second cell layer or selecting a radio access technology for communication by a mobile device are provided. A device receives information indicative of an access assignment for communication. The access assignment is generated based on a defined criterion, which is associated with a policy of determining a cell layer assignment prior to determining a radio access technology (RAT) assignment. In response to receiving the information, the device can update its configuration to transmit via a transmission parameter based on the information. The cell layer assignment can offload traffic from the first cell device to the second cell device while the RAT assignment can re-assign the device from a first RAT to a second RAT. Assignment can be based on network conditions or mobility state or applications of the device.

Facilitating intelligent radio access control

Mobility management may be utilized to effectuate handover and route packets of information to one or more radio access technologies and/or cells/access points based on network, UE conditions, device location, and/or network entity location. Packet routes, device addresses, handover functions, dynamically may be adjusted based on the best radio technology, cell layer, service provider specified criteria, or the like.

Mobility management

An optical network unit (ONU) is installed to communicate with an optical line terminal (OLT) located at a remote terminal (RT). The ONU includes a first subscriber downlink interface to serve a first subscriber premises and a second subscriber downlink interface to serve a second subscriber premises. The RT is located apart from a central office (CO) and in communication with the CO. A first removably attachable subscriber downlink module is communicatively coupled to the first subscriber downlink interface. A second removably attachable subscriber downlink module is communicatively coupled to the second subscriber downlink interface. The first removably attachable subscriber downlink module is replaced with a third removably attachable subscriber downlink module. An optical transmission medium is connected between the third removably attachable subscriber downlink module and the first subscriber premises while retaining a second electrically conductive medium communicatively coupled to the second subscriber downlink interface.

Methods and apparatus to upgrade communication services in subscriber distribution areas

A communications network is operated by providing a plurality of redundant links between a first network node and a second network node. A first identifier is associated with a first one of the plurality of redundant links and a second identifier is associated with a second one of the plurality of redundant links. The first and second identifiers are associated with the regulatory constraint. Traffic that is marked with the first identifier is routed to the first one of the plurality of redundant links and traffic that is marked with the second identifier is routed to the second one of the plurality of redundant links so that operation of the communications network is in compliance with the regulatory constraint.

Methods, systems, and computer program products for routing traffic between nodes in a network that are connected by redundant links

A system that incorporates teachings of the present disclosure may include, for example, a Power Over Ethernet (PoE) device (PD) having a controller to receive signals over a first cable having twisted pair wires from at least one of a network element and a gateway where the network element is associated with a service provider where the gateway is associated with a premises and where the service provider provides network communications to the premises, adjust the signals, transmit the adjusted signals over a second cable having twisted pair wires to at least one of the network element and the gateway, and receive power from at least one of the network element and the gateway, where the power is received over at least one of the first and second cables, where the power is received according to PoE protocol, and where the PD is positioned between the network element and the gateway. Other embodiments are disclosed.

Apparatus and method for providing network communications

An MPLS network is operated by pushing a plurality of MPLS shim headers onto a packet at network node. The packet is replicated to obtain a plurality of packets for transmission on a plurality of paths associated with a plurality of nodes, respectively. At least one MPLS shim header is popped from respective ones of the plurality of packets. The one or more MPLS shim headers that are popped correspond to at least one of the plurality of nodes that is not associated with one of the plurality of paths for which one of the plurality of packets comprising the one or more MPLS shim headers is destined for transmission. The plurality of packets is then transmitted on the plurality of paths, respectively.

Methods, systems, and computer program products for pushing and/or popping multiple multiprotocol label switching (MPLS) labels/shim headers at a single node

A system and methods for providing services through an integrated digital network. The present invention embodies a system and methods for providing telecommunications services through an integrated digital network that provides the superset of all previous network types, and can continue to support being the core for existing networks&#x2014;now used simply as edge access methods. The method includes connecting a multi-service core to existing telecommunications networks, wherein the core can communicate with conventional network components; interconnecting a gateway between the multi-service core and multiple existing network components, wherein the gateway is configured to share multiple service aspects with each network component and to utilize multiple transport protocols to communicate with different core network components; coordinating communications between the gateway and existing network components; and resolving differences between protocols or communications between existing core network components.
