    Abstract: An overlay network is contemplated. The overlay network may be characterized as supporting, or at least virtually supporting, separate networks over a common infrastructure. The common infrastructure may be comprised of a plurality of routers or other devices configured to facilitate directing messages according to various addressing requirements. The use of the separate networks may be dictated according to the particular addressing requirements of each message desired for transport.

    Abstract: Systems and methods presented herein provide for a software defined network (SDN) controller in a cable television system that virtualizes network elements in the cable television system to provide content delivery and data services through the virtualized network elements. In one embodiment, the SDN controller is operable in a cloud computing environment to balance data traffic through the virtualized network elements. For example, the SDN controller may abstract Layer 2 Control Protocol (L2CP) frame processing of the network elements into the cloud computing environment to relieve the network elements from the burdens of Ethernet frame processing. In this regard, the SDN controller comprises a L2CP decision module that determines how L2CP should be processed for the network elements in the cable television system.

    Abstract: Systems and methods presented herein provide for a software defined network (SDN) controller in a cable television system that virtualizes network elements in the cable television system to provide content delivery and data services through the virtualized network elements. In one embodiment, the SDN controller is operable in a cloud computing environment to balance data traffic through the virtualized network elements. For example, the SDN controller may process a request for content from a user equipment (UE), determine a bandwidth capability of the UE, determine that bandwidth of the requested content exceeds the bandwidth capability of the UE, analyze the bandwidth capacity of the network elements, generate a virtual channel through the network elements based on the bandwidth capacity of the network elements, and to deliver the content to the UE through the virtualized channel.

    Abstract translation: 本文提出的系统和方法提供了有线电视系统中的软件定义网络（SDN）控制器，其虚拟化有线电视系统中的网络元件，以通过虚拟网络元件提供内容传送和数据服务。 在一个实施例中，SDN控制器可在云计算环境中操作以平衡通过虚拟网络元件的数据流量。 例如，SDN控制器可以处理来自用户设备（UE）的内容请求，确定UE的带宽能力，确定所请求内容的带宽超过UE的带宽能力，分析网络的带宽容量 元素，基于网络元件的带宽容量通过网络元件产生虚拟信道，并且通过虚拟化信道将内容传递给UE。

    Abstract: Network address translation of messages transported over an autonomous system between multiple network elements is contemplated. The network address translation may be performed by instructing one network element to translate upstream messages for a particular messaging paths and a different network element to translate downstream messages for the same messaging path, thereby providing split network address translation.

    Abstract: Address translation sufficient for use in translating addresses included in messages carried or otherwise transmitted between inside and outside network is contemplated. The contemplated address translation may facilitate operation of a network address translator (NAT), carrier grade network address translator (CGN), or other device similarly configured to facilitate translating inside addresses used to address messages carried over the inside network relative to outside addresses used to facilitate carrying messages over the outside network.
