    I heard something about this new tecnology of MODEM BONDING, which lets you use more than one ISP service(DSL,CABLE,SATELLITE,FIBER, FIBER-OPTIC,WIRELESS,etc.) on one particular modem. The router then can request information using any of the service lines connected to it and obtain the info. from which line responded quicker, the info. requested is sent through the ISP gateways and splits the signals into one .

    This stuff sounds pretty coll for streaming media.

    The benefits is that if you have a bad DSL Line or the satellite connection goes out during a storm or the cable as well, the modem can request from the other one or two services at the same time to see who responds quicker.

    Seems like only rich people could afford this and its the fastest way to connect to the internet and download streaming media in seconds or less.

    I'm not sure I'd call it new... Don't forget Multilink PPP, it was the first channel bonding implementation I saw used and that's from 1994. I remember that there was a Windows dial up networking update for Windows 95 that supported it too... and Windows 98 had it built-in from the first release.

    However I'm not sure what you describe should properly be called bonding, it's more of a multihoming (i.e. ISP load balancing) implementation. To make it transparent such as you describe, with one IP address range "shared" across two ISPs, you have to use inter-domain routing using BGP (Border Gateway Protocol) from 1995, which replaced EGP (Exterior Gateway Protocol) from 1984.

    Well I saw this "MODEM BONDING" stuff in a news chat and I heard it was going to be implemented in 2006: Some new modem with a built-in router that will have one rj-45 port, rj-11 port, fiber-optic port, and cable port. It can connect a PPP link seperated from a cable AND/OR fiber-optic or wirless link.

    All the links are connected to their own ISP's gateway, but the modem selects the best link (speed,condition,&traffic)-during the selection process a host machine connected to the modem requests info.(Ex: Music files) over the internet and the requests are sent through all links available=the signals on the line is split into one signal after the transmission point when gathering the data from the internet and then when presented to the user.

    Its like saying you have a modem or router for cable, another for DSL, another for satellite, and/or another for fiber-optic. Each of these modems or routers connect to the internet, but in a different way based on speed, way of transmission(such as laser or electrical signal), and the material that protects from interference.

    Fiber is faster than DSL, but DSL has alot of support tools for establishing connections and in some cases more reliable if the a cable connection can't be fixed by its ISP. So basicly these different services over rule each other on different advantages, if it was possible to have a modem or router to have all of theses services at the same time then the need for connection support or more speed "WON'T" be an issue anymore.

    In basic terms this is called INVERSE MULTIPLEXING.
