Embodiment Construction

[0016] Figure 1 shows a first solution of the invention, in which a web server 1 is connected to a router 3 (also called a local gateway or L2TP server) via any suitable type of transmission link 2, wherein the web server 1 forms a Interface to the Internet (not shown) and operated by, for example, an Internet service provider or corporate intranet service. The router 3 is in turn connected to a network access server or local access concentrator (LAC) 5 via an Internet Protocol (IP) network 4 (eg, a multi-service platform). The user terminal 7 is connected to the router 3 with a dial-up connection through an ISDN (Integrated Services Digital Network) 8 or a PSTN (Public Switched Telephone Network) 9 and a modem 10 connected to the LAC 5 .

[0017] It should be understood that each server computer 1 has its own local gateway 3, although there may be, and there will generally be, many servers and gateways connected to the network 4 .

[0018] As mentioned so far, the scheme is ...

Abstract

An interface (1) to a network such as the internet is connected via an access network (4) to user terminal (7). Interposed in this path is a branch point (3) which divert some (though not all) of the data traffic from the interface (1) to the terminal (7) via an alternative path such as a satellite link (12, 13, 14, 15). Its decision as to which path to follow is made by examining the contents of that item.

Description

technical field [0001] The present invention relates to telecommunications networks, and in particular to the provision of broadband telecommunications services such as may be used for the Internet and similar services. Background technique [0002] Today, there is a growing demand for broadband services to support a wide range of information services to end users, including, for example, electronic mail, Internet and Intranet access, file transfer, and audio and video program distribution. One existing solution to this has been the development of Asymmetric Digital Subscriber Line (ADSL) services, whereby communication in the downstream direction (e.g., from an Internet Service Provider (ISP) or corporate host to their end users) provide relatively high bit rates. (ADSL and its variants such as VDSL (Very High Speed ​​ADSL) are often referred to as "xDSL"). However, they all have certain disadvantages. In particular the use of twisted copper pairs has limited reach, and ...
