    Does anybody know where i can get real time performance of ISP

    I know one exists but cant find it anywhere?

    thanks in advance

  3. ?

  4. 1. What technology are you getting from the ISP (Frame Relay, MPLS, PPP,
    2. What is a use for the service (Internet, dedicated circuit, voice
    circuit, etc)?
    3. What do you use the connection for (Internet browsing, Internet hosting,
    IP Telephony, etc.)
    4. .... etc.

    There are hundreds variants of using an ISPs. And depending of your goal,
    some tools could be useful in one case, and useless in another. For example,
    if you use the Internet for just browsing, the performance may be affected
    by (a) Your carrier, (b) intermediate circuits, (c) destination carrier, and
    (d) end host. For TCP applications jitter or latency have minimum impact,
    while for VoIP may be crucial. Most applications just do a PING or
    TRACEROUTE to a host you pick, but you cannot really tell why it behave one
    way or another. You need to decide what is most critical for you (for
    example, for VoIP "round trip delay", jitter, latency, etc.) and look for
    tools, provided by the router manufacturer. In case of Cisco, you may spend
    some money, and implement a Cisco NAM (Network Analysis Module). Or get IP
    SLA collector, and configure it to monitor your VoIP peers. Or get a span
    session to a sniffer, which will analyze traffic in a real time. But if you
    use a service for an Internet hosting, then you may be more interested in a
    TCP performance, in application response time, etc. And getting back to a
    technologies, you use. If you suspect, it's a "last mile issue", monitor a
    router for a technology-specific parameters, like dropped packets, "slowdown
    packets", etc.

    Good luck,
