With nVoy, these devices become easier to set up and integrate in your network

There have been some previous methods available to allow one to manage a network from their desktop. One of these was SMNP which is used primarily to manage equipment in larger networks and is very difficult for anyone to use unless they had good IT skills. Another of these is TR-069 which was developed by the Broadband Forum for use by ISPs and telcos to set up and manage consumer modem routers.

These protocols, like a lot of other network discovery and management protocols relied on an operational network existing between the controller and the controlled device. Similarly, they haven’t work well as a way to allow an average householder or small-business owner to manage a small network effectively and with minimal help.

But a newer specification, known as the iEEE 1905.1 control specification had been set in stone and declared formal. It is now marketed as the nVoy specification and works at a level to manage network segments at the media level.

This is very important with the home-network setups that I prefer and stand for where there is an Ethernet and/or HomePlug AV wired network backbone along with an 802.11n Wi-Fi wireless network segment covering the property where the network is set up at.

This allows logic to be constructed to manage a Wi-Fi, HomePlug AV, MoCA or Cat5 Ethernet segment that is part of the typical home network without having to have a full IP logical network being alive across the whole network. It also means that media-peculiar network-setup and diagnostics parameters like the ESSIDs and WPA2-Personal passphrases required for wireless networks can be propagated over different network media like Ethernet or HomePlug wired-network segments.

This simplifies setup routines like creating new Wi-Fi wireless or HomePlug AV powerline segments in a secure manner; or adding additional network devices to the existing heterogenous multi-segment small network. It even encompasses the establishment of secondary access points in order to extend the coverage of a Wi-Fi wireless network in a “cellular” fashion.

The user experience would be based on using NFC “touch-and-go” setup or two-button “push-push” setup of new Wi-Fi and HomePlug devices. As well, you would be able to manage the network from devices that use a full management interface, whether local to the network or remotely via something like TR-069 or SMNP.

Even through the life-cycle of the network, the nVoy specification can allow one to use a management interface at one single point of control to bring up diagnostic information about the network or parts thereof so as to identify points of failure or to optimise the network for best performance. The fact that nVoy is determined as a standard could allow computer operating-system developers to bake this function in to subsequent versions of their operating systems and establish one point of control in the operating system user interface.

Beyond the ease of setup and troubleshooting that it offers for small networks, nVoy has the ability to enable easy-to-manage “multiple concurrent pipe” connections in an easy-to-manage form. This allows for two or more connections to be aggregated for higher throughput, as a load-balancing arrangement so that particular traffic can go via one connection while other traffic goes via another connection as well as a fail-over arrangement if things don’t work out on one pipe. This will be more real with the common practice to equip most client devices with two or more network “on-ramps” such as Ethernet and Wi-Fi wireless.

Personally, I would also like to see nVoy work with most client devices in extending their network abilities. For example, a network printer or consumer AV device that has integrated Wi-Fi wireless and a wired connection like Ethernet or HomePlug be able to allow you to set up the Wi-Fi connectivity as an access point if it is connected to the network via the wired connection. Similarly, the same device could be set up as a wireless client bridge for another device like a PS3 or Blu-Ray player that is connected to the Ethernet socket on the device when it is connected via the wireless connection.

Similarly, the nVoy specification could also tackle quality-of-service for IP telephony, AV streaming and real-time gaming so as to guarantee throughput for these network activities. As well, when standards evolve for synchronous “broadcast” network activity on the different media such as for multi-channel wireless speakers or party-streaming modes, nVoy could be used to support network-wide synchronising abilities for these applications.

What I applaud about nVoy being set in stone is that the small network becomes easier to manage whether it is based on one segment or medium or uses many different segments or media.

Consumer Electronics Show 2012–Part 3

simonmackay 13/01/2012 Consumer Electronics Show (January - Las Vegas USA) No Comments

Network Technology

There are a few major trends that I have noticed for the home and small-business network at this year’s Consumer Electronics Show. But the big names like D-Link and NETGEAR had chosen to run private showings of their products in the many hotels around Las Vegas rather than use the Convention Center.

Wireless networking

The 802.11ac Gigabit wireless network standard has been ratified and a lot of the manufacturers are showing prototype chipsets and endpoint devices for networks based on this standard. TRENDNet had shown a router and a client bridge as a proof of concept for a wireless link on this standard and D-Link had registered interest in developing their 802.11ac implementation.

On the other hand, Belkin, D-Link and Engenius ran with premium “N900” routers as their top-shelf models. These are simultaneous dual-band routers that run three data streams on each of the two Wi-Fi bands with a total theoretical throughput of 450Mbps per band.

As well, TRENDNet had tried their effort at another of those “universal Wi-Fi range extenders” which is a device class that could cause some mistakes.

Coaxial and Powerline Networking

MoCA have brought their TV coaxial-cable network specification up to 2.0 which allowed for a headline speed of 400Mbps with Broadcom showing a system-on-chip that works with this standard. They were pitching it at the set-top-box market, especially for multi-room cable-TV deployments.

On the other hand, HomePlug PowerLine Alliance have made the HomePlug AV2 specification official. This standard, which is interoperable with HomePlug AV powerline network segments can support MIMO / repeater operation for a robust powerline segment as well as allowing for a Gigabit physical-layer bandwidth for this segment. The former MIMO advantage makes it that each HomePlug AV2 node acts as a repeater and can take data from two or more nodes for higher throughput even with ropey mains circuits.

But there have been more of the HomePlug AV 500 devices being exhibited on the floor; including D-Link’s DIR-1565 “three-way” router which supports a network of 802.11g/n Wi-Fi, Gigabit Ethernet and HomePlug AV 500.

Also, the IEEE 1905.1 standard has been officialised thus simplifying the setup and management requirements for small networks that use Wi-Fi, Ethernet, HomePlug or MoCA network media or a combination thereof. It also provides a consistent quality-of-service arrangement for data that passes through the different network media.

Routers

Some of the manufacturers were pitching at the idea of “cloud-enabling” their routers. This was to allow for remote management of these devices or to allow the router to become an Internet-enabled file server. There was also some talk about setting up app platforms for routers, but what could this lead to for the evolution of these devices.

D-Link have launched the DIR-505 which is a 802.11g/n Wi-Fi plug-in travel router which also had the ability to work as an access point and file-server.

Network-Attached Storage

TP-Link had used this show to launch their first NAS unit which was a DLNA-capable 2-bay SATA unit with Gigablt Ethernet connectivity as well as 3 USB ports. It even had the ability to copy from USB to NAS at the touch of a button.

Iomega had refreshed their StorCenter NAS lineup by adding a surveillance-camera NVR functionality and making them easy to setup. This also included improving their cloud-storage functionality. They also introduced the EZ Media & Backup Center which was their entry-level home-user NAS which supported easy-setup operation and backup, iTunes / DLNA media serving and support for Iomega’s Personal Cloud and Iomega Link technology.

Broadband Internet

ViaSat, who provide the satellite backhaul for JetBlue’s inflight Internet service, were intending to launch a satellite broadband service for rural America this year. They wanted to use this show to exhibit their proposed service. This service is intended to be speed-competitive with the fastest terrestrial broadband services in the cities and is to be known as Exede.

The throughput is at a headline speed of 12Mbps download / 3Mbps upload and they are offering packages with monthly rates US$49.99 for 7.5Gb data allowance, US$79.99 for 15Gb data allowance and US$129.99 for 25Gb data allowance.

Conclusion

This year, the Consumer Electronics Show in Las Vegas was about estalishing a connected home lifestyle across all of the main activity centres ranging from the home office to the lounge area and that the TV is now a legitimate part of the connected lifestye.

Realities

More home networks implementing two or more media backbones

As the typical home network evolves, there will be a time when another interface type will be implemented in that network.

There are two examples of this common situation. One is where a person who has run an Ethernet network from the network-Internet edge to their computer decides to “go wireless” with their laptop computers and upgrades to a wireless router yet maintains the Ethernet connection for desktop computers. Another example that is increasingly common in Europe and will become so with the prevalence of IP-delivered TV would be a household that has a Wi-Fi network for the laptop but implements a HomePlug powerline network to serve the set-top box or IP-enabled TV in the lounge.

Infact I have advocated these kinds of network setups in this site in order to encourage a flexible home or small-business network that suits all situations that are thrown at it. This includes handling radio-difficult environments like double-brick walls or foil-lined insulation that can exist in many houses.

Network endpoint devices with multiple network interfaces

An increasing number of network-endpoint devices like computers, printers and Internet media devices are being required to support multiple types of network interfaces. This may be provided out of the box; or the user may have to install a hardware network adaptor for a particular network interface in to the device even though the device has an integrated network adaptor for another interface.

A very common example that I have seen for myself is laptop users switching between a wired Ethernet connection and a Wi-Fi wireless connection. Typically the laptop user who is getting used to the “New Computing Environment” and what it offers will plug their computer into the router’s Ethernet socket while they work at their desk; then disconnect from the Ethernet socket and “go wireless” when they want to use the laptop in other parts of the house. This typically can cause problems due to network storms or switchover problems; and often requires the user to disable or enable Wi-Fi on the laptop as they change connections.

Similarly, most of the network-enabled multifunction printers that I have reviewed at HomeNetworking01.info are equipped with an Ethernet socket as well as an integrated WPA2-secured Wi-Fi interface. This is becoming very common with most network-enabled media players, especially “smart TVs” and BD-Live Blu-Ray players.

Setup and management difficulties with these networks

These networks can yield their fair share of difficulties as users have to set up each network segment or device for secure reliable operation. This can include initial provisioning needs that a media type has like SSID and WPA-PSK security keys for Wi-Fi segments to management of segment-specific problems like Wi-Fi reception issues.

It will become more difficult as advanced networking requirements such as quality-of-service, synchronous media streaming, multiple logical networks and robust security are required out of these small heterogenous networks.

In the case of the devices, it will include making sure that the device works with the best network interface available even if both interfaces are physically connected. The most common example of this is making sure that the Wi-Fi-enabled laptop or printer works on a wired link if connected to the network via that link and works with the Wi-Fi link in other cases without the need for a manual switchover procedure.

What is this new standard intending to provide

You may think that there are standards out there to help with managing a computer network but most of these standards work to a particular network media type. As well, a lot of them require management by an IT team, something which few households or small businesses can have on hand all the time.

One major benefit is simplified media-level control across different media types on the same network. This isn’t achieved through the use of higher-level configuration routines managed by IP or application-level protocols like SNMP or UPnP, but these protocols can be adapted for this standard.

There will also be a focus on end-to-end performance such as allowing a device to choose the network interface that provides best throughput and quality-of-service. It can also allow “end-to-end” quality-of-service to be achieved from the network-Internet “edge” to the end device for IP telephony, multimedia streaming or Internet gaming.

Similarly, there is the ability to manage the media-level network security and energy-management needs that are required for the network in an easier form. This includes coordinating device wakeup across different media types so that a device can exist in an energy-saving quiescent mode yet “come to” when someone else on the network need it no matter how it is connected.

This standard recognises the reality that no one network type suits all needs, different horses for different courses.

Here, a typical setup may use Cat5 Ethernet as a high-speed backbone between floors or across the house, a HomePlug AV segment as a high-reliability wired “no-new-wires” setup for temporary applications and a Wi-Fi wireless segment that is primarily for portable devices.

The main focus that will be achieved is that bridge or switch devices that work across the multiple media types can perform these jobs more efficiently without needing to use higher-level protocols to achieve this goal; and be assured that the requirements for the network data are met as the data travels these devices.

Unanswered questions

Support for and management of VLAN networks

An unanswered question about this standard is whether it can support a VLAN network. This is a network that hosts multiple logical networks across the same physical infrastructure. It would be relevant in the small network space for “guest / hotspot networks” and IPTV setups where end-to-end content protection is required.

Features that may be considered of importance in this regard include replicating VLAN setups across the network as infrastructure devices are added to the network. An example of this could b to use an extension access point to “build out” a Wi-Fi network yet maintain the “guest network” and the “private network” as separate entities with separate SSIDs.

It also includes multi-tenancy-building environments where there is common “LAN” network infrastructure like cable runs that exist to interlink units (apartments, shops, offices, etc) or multi-SSID access points installed to service common areas (common gardens, swimming pools, food courts, etc). Here, it would be required to establish a VLAN interlink between two or more premises under the control of the same entity or establish a link to a common multi-SSID access point with the same SSID and security parameters as your main access point.

Wi-Fi devices and their operating mode

Another questiom that may affect the management of Wi-Fi devices is what kind of operating mode the device should be in. This is whether it is a client device or an access point; or to implement “direct link” or WDS or newer-standard network repeater functionality.

This would cater for an increasing number of “multi-function” access points which was a trend brought about by newer firmware versions for the Linksys WAP54G wireless access point. Here, the access point could be set up to be on the end of a direct wireless link, or be a client bridge for an existing Wi-Fi segment, a Wi-Fi repeater as well as being an access point.

This standard could provide support for a wireless endpoint such as a "multi-function” access point or the Wi-Fi functionality in a printer or other device to work as a client device or as an access point. It could then allow for these devices to quickly serve as infill access points when they are connected to a wired backbone after working on the Wi-Fi network.

Conclusion

At least the IEEE P1905 standard will make some effort towards making the establishment, management and development of the typical heterogenous small network become an easier talsk that is less painful.
