IPv6 Experiments in Deploying and Accessing Services from Home Networks

Users are increasingly nomadic and want to access their home network from anywhere. Such remote access might also be granted for family members or friends and controlled by the home network owner on a per device basis. This paper describes an overall sound solution for a layer 2 VPN, providing one-click access to the home network. Layer 2 VPN transports all home network protocols, including multicast, UPnP, Windows shares, thus providing full home network experience to remote users. Our solution addresses several practical and technical is- sues such as MAC address filtering and IP collisions. Our solution enables in particular per-device security policy enforcement while sharing the same access credentials with several remote users. We implemented and tested the solution by extending OpenVPN and a home gateway.

Electrical appliances of the home network via the Internet can be controlled using the ZigBee system and the UPnP expansion like the ones in the same home network without the modification of the existing UPnP. In this paper, we propose an Internet gateway that consists of ZigBee and the UPnP IGD (Internet gateway device) DCP(device control protocol) and the UPnP bridge for the control of electrical appliances of the Internet home network with a low data rate and low power consumption. ZigBee technology is a low data rate, low power consumption, low cost, wireless networking protocol targeted towards automation and remote control applications. The UPnP IGD DCP is the configurable initiation and sharing of Internet connections, advanced connection-management, management of host configuration, and supports transparent Internet access by non-UPnP-certified devices. The UPnP bridge searches for local home network devices by sending control messages. Control points of the UPnP bridge searches for devices of interest on the Internet and can deliver the control devices on other home networks to devices within its home network. With our approach, devices can control home electrical appliances and ZigBee System via Internet through IGD DCP on other home network with control commands of the UPnP.

Home network systems including a home gateway are expected to facilitate the convergence of broadcasting and communication services to complement the ubiquitous computing and services. We focus on supporting the convergence of broadcasting and communication in home network systems with an Ethernet passive optical network (EPON)-based home gateway. We propose a new architecture that integrates broadcasting and data services in a home network. For this architecture, we use an overlay transport mechanism in access network and IP multicast techniques of the Internet group management protocol (IGMP) and IGMP snooping in a home network. We also detail a set of mechanisms and procedures for a home broadcasting service through the home gateway system. Our new scheme is composed of three parts: a) an overlay transmission model of video broadcasting signals (satellite and/or cable TV) and Internet data, b) to select a specific video broadcasting channel and video broadcasting stream into IP multicast packets in tuner/conversion module using multiple tuner system and c) to transfer the converted IP multicast packets to L2 switch of home gateway's core module and to send them out to target port(s) by L2 multicast using IGMP snooping.

In this paper, we present the design and implementation of an UPnP based media distribution system supporting priority-based Quality-of-Service (QoS) in a home network that converges data and multimedia traffic. We adopt two UPnP based standards, the UPnP AV architecture and the UPnP QoS architecture, for multimedia networking and QoS management among networked devices, respectively. Additionally, the IEEE 802.1p/Q is adopted as a priority-based QoS scheme for an Ethernet-based home network. By combining two adopted architectures with the 802.1p/Q QoS scheme and integrating them into a home gateway and multimedia devices, our system offers not only interoperability of media distribution among different networked devices but also easy to use management of QoS for multimedia.

Recently, there has been much effort in providing information technology into home appliances. Home network may link appliances, sensors, actuators, switches, controllers, and user interfaces to create novel applications and provide an infrastructure for multimedia distribution. However, there are various technologies of the home networking, which makes it difficult to give only one solution. Many developers and standardization organizations considers a home gateway as a good solution. In this paper, we propose a new architecture of a home gateway supporting various home network technologies such as IEEE1394, Bluetooth, LonWorks, wireless LAN, HPNA or implement Bluetooth technology using IP as a test model for our home gateway.

Home network complexity is dramatically growing in terms of topology (devices and connectivity technologies) and services leading to increasingly challenging management issues. In this context, enabling a better visibility of home network traffic usage and performance is a crucial step to provide efficient selfcare and customer care. In this paper, we study home network traffic monitoring architectural approaches. In particular, we study the feasibility of Home Gateway based flow monitoring approach, which will allow enhancing home network diagnostic and performance tracking. Our experimental evaluation aims to provide a better understanding of deployment possibilities and limits. The obtained results based on an open source tool are promising in terms of resource consumption (CPU and memory load, bandwidth utilization).

In the age of technology, most of the network services originally run on large scale and base on complicated systems. When they’re brought into our home, the migration could derive further technical problems due to the change of scale and cost. Home networking structure is often improvised and built up with several types of wireless technology, such as WiMedia and WiFi, inside several small rooms. In addition, people enjoy walking around at home and being served without constraints and service interruption, so the seamless services and mobility within home are a must. This paper describes a novel notion on the transition among wireless connectivities at home which is named Hand-around and efficiently provides seamless network services while moving in heterogeneous and improvised home networking. A developing technique in Mobile IPv6, called multiple care-of addresses (MCoA) registration, is the best candidate to accomplish such seamless services in an all-IP home network. Besides, it’s a pure layer-3 mechanism and hence could more easily apply on and adapt to home services without massively changing the operational flow and system hierarchy, especially suited for services of multimedia, communication and entertainment. This notion also gives a new vision to some scenarios described in Home Gateway Initiative (HGI) document.KeywordsHome networkingHome gatewaySeamless serviceMobile home serviceMultiple care-of address registrationHeterogeneous networks

We propose a proxy-based scheme for segment-based distributed streaming services among UPnP(universal plug and play)-enabled home networks. We design a "SHARE" module that extends HG (home gateway) with a UPnP-compatible protocol. By relaying SSDP (simple service discovery protocol) messages defined in the UPnP device architecture, the SHARE module provides connectivity that is needed to control other UPnP devices for streaming services among home networks. To provide the streaming services, the SHARE module tries to coordinate the distribution of streaming loads among multiple senders by using many-to-one distributed streaming service. It also tries to minimize the quality degradation of streaming services based on the system and network resource status of each sender by leveraging the UPnP QoS services. That is, pre-allocation of HG resources according to the UPnP QoS services can be used to improve the quality of streaming services. Based on the UPnP components, the SHARE module provides the transparent content sharing to users. Through design-level verifications and partial implementations of the proposed SHARE module, we validate the feasibility of our work.

Admission region of triple-play services in wireless home networks

Radio interface and wireless service accesses are two areas, in which wireless networks do not provide the same level of protection as wired networks. It may result in the wireless networks being vulnerable to various attacks. For example, the first generation cellular mobile communication systems, such as advanced mobile phone service (AMPS), and the second generation cellular mobile communication systems, such as global system for mobile (GSM), do not take account of security issues comprehensively. It brings about an intruder to be able to eavesdrop user traffic or even change the identities of mobile phones to gain fraudulent services. Therefore, the Universal Mobile Telecommunication System (UMTS), which is known as the third generation (3G) cellular mobile communication system, is proposed. UMTS adopts the security feature of GSM in order to interwork with GSM smoothly. Furthermore, the UMTS adds new security features to design an authentication and key agreement protocol, which is called UMTS AKA protocol. However, it is found that the UMTS AKA has some problems, including bandwidth consumption between a serving network and a user's home network, space overhead of the serving network and sequence number synchronization. Therefore, in this paper, we propose an extension of UMTS AKA protocol, called UMTS X-AKA to overcome the aforementioned problems of UMTS AKA.

To maintain network efficiency of a home network, it is crucial to moderately distribute limited data throughput and bandwidth resources to various home devices and services that require different network resource provisions. This paper accounts for QoS differentiation and fairness of network resource allocation which are essential to the design of an efficient IoT-based home media delivery mechanism against network traffic dynamics. Accordingly, our study in this paper proposes a QoS-prioritised media delivery mechanism with adaptive data throughput. This mechanism design includes several functions: assigning weights of relative importance to home service types, adjusting media quality of home services, reducing data workload against traffic congestion, and fairly distributing free bandwidth to prioritised home services. Furthermore, our study fulfills a simplified proof-of-concept implementation in a small-scaled IoT-based home network. Practical experiments can generate real measure data for performance examination. Results show that the proposed mechanism is able to sustain not only QoS differentiation like data throughput and delay, but also fair user satisfaction with comfortable media playing quality.

PurposeThe number of home networks, as well as the number of services and hosts in them, is increasing. Often home users cannot get public IPv4 network allocations from service providers and are forced to use network address translation (NAT) and port forwarding to solve connectivity issues to the different home services. This paper seeks to introduce a secure connectivity solution utilising both IPv6 and IPv6 transition mechanisms in cooperation with existing virtual private network (VPN) solutions.Design/methodology/approachThe proposed solution to avoid route conflicts and other problems with private IPv4 address space collisions is to utilise 6to4, an IPv6 transition mechanism, to obtain routable IPv6 network addresses first for the home network and services and then, to utilise the same IPv6 network for connectivity by bridging it over a VPN connection to the mobile terminal.FindingsThe paper finds that the adoption of this solution and these technologies will depend on how useful they are seen by vendors or service providers and included in their products. Regular vendors and service providers probably want to wait until there is a greater customer need. On the other hand, customers do not know about the possibilities before they are shown to them in practice. The best approach to this challenge is to find a cooperating vendor, or even better, a service provider willing to develop the concept further and to integrate it into the devices and services they are already offering.Originality/valueThe technologies for enhancing home service connectivity are already available. In the proof‐of‐concept implementation the paper has shown that all these components can be integrated and utilised to build home routers for present and future home networks. The technical disadvantages and challenges are solvable with further work and the whole concept is ready to be turned into products and services. As indicated in the paper, one of the issues for further work is to find and convince a vendor or service provider to integrate the proposed solution in their home router.

This paper proposes two systems. One is a Home Gateway(HG) which efficiently connects and controls digital appliances in the home network environments. The other is a Management Server(MS) that overcomes the physical limitation of the HG. The HG supports networking modules(TCP/IP for Ethernet, ADSL), home networking functions(HomePNA, IEEE1394 PLC) and telecommunication system(PSTN/SLT, VoIP, Video Communication). The HG is expected to be a core device for the integrated digital home environments. The MS is a dedicated server which manages and controls individual HG, home appliances and HA devices implemented at an area.

Mobile agent technology is very useful in home network environments and ubiquitous environments. For several reasons, a particular mobile agent may fail to operate during its movement between various platforms. For mobile agent recovery, a checkpoint can be used. However, devices in home network environments generally have minimal or no secondary storage. Therefore, a checkpoint cannot be saved on the device within a home network. In this paper, a scheme that safely recovers a mobile agent using a checkpoint saved within the home gateway is presented. When the mobile agent enters the single home network environment, , it registers its recovery policy and saves its checkpoint on the home gateway. At the checkpoint saving instance, a symmetric key generated by the home gateway encrypts the checkpoint, this symmetric key is also encrypted and stored together with the checkpoint. When the mobile agent is abnormally terminated or the device suddenly turns off from battery exhaustion or failure, the home gateway recognizes the exception in the mobile agent or device, recovering the mobile agent with the checkpoint according to the previously registered recovery policy.
