One Big Broadband Hot Spot

This isn't the Cosmo magazine kind of hotspot; it's the other kind you may be hearing about: the Broadband hotspot. They seem to be everywhere, you can sip a latte in Starbucks while browsing the net, or have a pint at the pub while you delete annoying emails from your mother But these little hotspots, once just covering a pub or a caf here or there, are growing bigger. Just last year the River Thames in London was made into a gigantic broadband hotspot that stretches for 22km from the Millennium dome to the Houses of Parliament. Anyone on the river or its banks can now whip out a laptop and start browsing. Bored of the view from the millennium wheel? Watch that hilarious video of a woman falling over on Youtube instead.

The River Thames hotspot works by mesh networking 100 access points, allowing users to connect to the net without interruption as they travel down the river. It comes at a cost, even if fairly inexpensive, and anyone with a wireless enabled device can connect for 2.95 for an hour, 5.95 for a day or just get a whole month for 9.95.

This gigantic hotspot seems insignificant however in comparison with the one being developed in Taipei, capital of Taiwan. Taipei has been engaged in a huge infrastructure upgrade that will be the foundation of a city wide broadband hotspot that will literally turn the city into one great bit hotspot. However the best laid plans for this city wide project have not gone as well as hoped, with only 30,000 or so subscribers to the service, far less than anticipated. This is partly due to a perceived unreliability in the network as well as abundantly available free hotspots in cafes and other such places within the city.

However while it may take a while for the city wide hotspot to catch on, it does seem like these gigantic wireless projects will be the way of the future. The growing integration of high speed internet into every aspect of our lives makes it inevitable that the infrastructure will be utilised - if not now then soon. Like many new technologies the factor seems to be cost- how many people will really want to pay to use the internet for a hour while they travel between a work and home where it is already paid for. How many people are really that anxious to be online at all times? When the costs match the needs is when we will start to see the full potential of such grand schemes.

Meeting Your Bandwidth Requirements For Supply Chain Management Applications

In today's business world it is critical for companies to deploy supply-chain management (SCM) systems to enhance efficiency across the product lifecycle by streamlining procurement, production, fulfillment, and distribution processes. Deploying an SCM solution that provides the intended return on investment requires that the applications, servers, and enterprise network infrastructure work together seamlessly. This is easier said than done and will necessitate a thorough evaluation of your bandwidth needs to meet the demand.

SCM solutions require integration of applications and data across multiple geographically dispersed supply chain partners, as well as internal integration with legacy systems. To ensure success, your organization must deploy robust, end-to-end dedicated bandwidth that delivers highly reliable and strictly monitored QoS (Quality of Service).

An SCM solution is only as strong as the weakest link in the chain. Access to SCM applications and data must be guaranteed for all of your users, inside and outside the enterprise. Your company must provide sufficient bandwidth to support constant data flow between desktops and servers at the company headquarters, geographically dispersed suppliers and partners, manufacturers, distributors, customer service call centers, and for mobile users and teleworkers. Connections between servers and desktops must provide the necessary bandwidth to deliver resource-intensive services, real-time application data to all users, and enable integration of disparate data sources.

At your headquarters office, where corporate Web, application, and database servers reside and WAN links converge, availability and security are key. A redundant backbone switching architecture with Gigabit Ethernet connectivity to servers and access switches is often indicated, along with a modular, enterprise-class routing platform that supports advanced security features and WAN bandwidth management.

In order to ensure availability over time, a successful SCM solution should be built on an application design, server architecture, and network infrastructure that can grow easily as your business grows. This is called scalability. The solution must provide the ability to easily provision more WAN bandwidth to meet peak needs, to scale with fluctuating traffic between vendors and partners, and to adapt quickly as supply chain partners are added or replaced. To accomplish this, the solution should readily accommodate new server connections, partners, and locations. Network routers should provide enough capacity to easily and economically provision additional bandwidth as traffic increases, or to add new locations as the geographic reach of the supply chain expands.

Each location involved in your SCM infrastructure will require dedicated bandwidth to meet the functions conducted at that location. This likely will involve some combination of the following choices and is dependent on the complexity of the deployed SCM system and the size of your organization:

- DS3 bandwidth, also known as a T3, is the reliable, all-purpose, digital connection for extremely high-volume requirements. Operating at 45 Mbps (equivalent to 28 DS1 circuits, or 672 DS0 channels), DS3 can provide a cost-effective solution for smaller locations in the SCM network. With DS3, you can link your high-volume host computers for resource sharing and load balancing.

- OC3 bandwidth is a fiber optic line delivering 155 Mbps (equivalent to 3 DS3 circuits) designed for those who expect constant, high bandwidth requirements. For a mid to large size business implementing a SCM system....this will likely be your choice for infrastructure backbone (e.g. headquarters) bandwidth.

- Gigabit Ethernet is a version of Ethernet, which supports data transfer rates of 1 Gigabit (1,000 megabits) per second. Large scale deployment of SCM systems and larger organizations will likely consider this solution.

The process to determine and than find the appropriate bandwidth solution for your SCM application can be a daunting task. Use of an unbiased professional bandwidth broker will save your IT staff countless hours of effort and headaches while guiding them through the technology minefields towards the best choice for system reliability and cost. I strongly suggest you take advantage of their expertise.
