Client device 105 may comprise, but is not limited to, a cable modem, a cellular base station, a tablet device, a mobile device, a smart phone, a telephone, a remote control device, a set-top box, a digital video recorder, a personal computer, a network computer, a mainframe, a router, or other similar microcomputer-based device. Node 110 may be deployed at an edge of a cable network (e.g., a Hybrid fiber-coaxial (HFC) network). Node 110 may comprise, but is not limited to, an amplifier or an Remote Physical Layer (R-PHY) node where the physical layer (i.e., PHY) of a cable headend Cable Modem Termination System (CMTS) (e.g., Converged Cable Access Platform (CCAP)) may be shifted to fiber nodes (e.g., R-PHY nodes) in a network comprising node 110. Client device 105 may be connected to and served by node 110.

Plurality of client service instances 125, transaction persistence module and load balancer 130, and plurality of target service instances 135 may comprise a plurality of Virtual Network Function (VNF) containers instantiated in data center 115 on server cluster 120. The plurality of VNF containers may each comprise software modules, that when taken as a whole, may provide functionality of a cloud Cable Modem Termination System (cCMTS) instantiated in data center 115. The plurality of VNF containers may reside on the same server (i.e., service cluster 120) or may reside on different servers or in different data centers. Notwithstanding, plurality of client service instances 125, transaction persistence module and load balancer 130, and plurality of target service instances 135 may be embodied in hardware and/or in software (including firmware, resident software, micro-code, etc.) and are not limited to being hardware devices.
