Sailing Angels is developing a managed telematics service network called DGN (digital image network). It provides users with high-speed file transfer services.
UPS is the world's largest company engaged in communications services. The UPS document Exchange developed by the company is intended to be used on the Internet. At present, UPS is doing basic work. Users can use the UPS online Courier to transfer files over the Internet. It has security options, tracking and receiving capabilities, or the user selects Online Dossier, a two-way encryption service that enables senders and receivers to have legitimate digital identities.
Sprint has announced that it uses a standard telephone line to provide commercial and home users with a virtual, unlimited bandwidth on demand. Sprint is calling this service the Integrated On-Demand Network (ION). Sprint's ION will integrate the networks now used by users and greatly simplify network management. In 1998, the first ION network was put into use and it is expected that ION will become popular in 1999.
Northern Telecom is developing a technology called Digital PowerLine. This technology allows data to be transmitted over the backbone network at 1 Mbps. The test system has been tested in the United Kingdom. The company said that Digital PowerLine will support high-speed Internet access, telephone systems and local area networks.
Factors to consider when establishing a network system In general, experts agree that there are several factors that influence how to choose a telecommunications network and system. The disagreement among experts lies in what factors influence decision-making? And how these factors are balanced and coordinated.
Point One: A network should meet three conditions: easy to use, affordable, and universal. The establishment of ISDN is not an easy task, but ISDN is easier to use and more reliable. At the same time, ISDN is based on a global standard that can be used worldwide and affordable. Of course, ISDN is not the only communication option, but it is the best and economically affordable solution in several network systems. ISDN is an entry-level system. If you need more features, you can choose a private network. Such as T1 or Wam! Net's any bandwidth network service.
If there is an infinite amount of data to be transmitted, the basic transmission rate ISDN is a great choice, but it must be networked. For relatively small or medium-sized image files (between several megabytes to tens of megabytes), ISDN is quickly transmitted within minutes. Each transfer fee is only a few dollars, so it is very affordable in this case.
With a certain kind of high speed connection to the Internet, even the system may be the general trend of transferring files. From a long-term perspective, a high-speed Internet connection is the cheapest way to transfer large files. If you want to transmit data to several companies in different locations on a long-term basis, you should seriously consider high-speed networks. If you have a private network that is at least 128 Kbps and the rate at which the transmission rate reaches TI, then the time to transfer large files is faster. Private networks are an important pawn for printing service companies, so printing service companies can send and receive documents in one place.
With high-speed TI or hierarchical TI and a backbone network connected to the Internet, relatively high work efficiency and reliability can be obtained, and even hundreds of megabytes of data can be transmitted. At the same time, when you think about ROI, don't forget that the Internet can provide other important values ​​for your business.
Point two: bandwidth, networking, and management. Not every company needs as wide a bandwidth network as possible. In the fields of prepress, printing and Web, speed, networking performance, and manageability are the factors that influence the size and type of network bandwidth.
Network bandwidth determines speed. High bandwidth usually means faster file transfer. To a certain extent, the user's computer equipment and non-bandwidth factors also affect the network speed. Networking capabilities, ie the ability to connect multiple points, can be achieved using dedicated point-to-point leased lines (T1 and T3), switching services (ISDN) or routing services (Wam!Net, Internet, ATM, frame relay, and satellite) .
When two users need to transfer large amounts of data frequently, the leased communication line is usually more affordable; when the user transmits data from time to time, not quantitatively between two points, the exchange service is usually selected as the most affordable; when the occasional transmission When it comes to data, such as Wam! Net routing services are the most cost-effective.
Management is the ability to operate a communications system. Router software has a technological innovation every two years. The computing platform will be updated once in the next 5 years. Companies with communications networks generally make major improvements every two years. Direct management costs more than indirect management. This is similar to Wam! Net is the charm of this managed communication service.
Point Three: Printing and Prepress Work Choosing the best telematics system should primarily consider three things: capacity, frequency, and time. The biggest failure of AT&T's Frame Relay network is the lack of a backup system. Interestingly, ISDN is an outstanding technology to provide backup systems, and load balancing is an added benefit of Frame Relay networks. This is because T1, Frame Relay, and ISDN are combined. For cost reasons, Frame Relay does not work for peak transmissions. ISDN improves this shortcoming of Frame Relay by increasing the bandwidth on demand, and it costs only fractions of Frame Relay.
