Abstract
A system identifies transmission routes between a user and a desired destination site on a wide area communications network, such as the Internet. The system then detects transit characteristics for each of the transmission routes. A user can request the level of activity on the routes. Thus, the user can be apprised of the existence of possible congestion in any attempt to access the desired destination site.
Claims10
A method for advising users of a communications network of a level of activity on the communications network, the method comprising the steps of:
- a) selecting a destination site;
- b) selecting an entry point into the network;
- c) tracing a transmission route, including a plurality of links and at least one intermediate point between said entry point and said destination site, from said entry point to said destination site;
- d) gathering transit characteristics information regarding said transmission route by detecting occurrences of packet loss and measuring round trip transmission delay, on at least one of the links;
- e) determining a network activity status based on said transit characteristics;
- f) storing the network activity status;
- g) receiving a request for a level of activity on said network related to said destination site;
- and
- h) reporting activity status based on said stored network activity status, in response to said request.
A method of reporting congestion level information associated with accessing a destination address of a wide area communications network comprised of a plurality of interconnected data communications networks, the method comprising the steps of:
- monitoring traffic level on a plurality of links connecting an access provider network to the destination address of the wide area communications network by detecting occurrences of packet loss and measuring round trip transmission delay, on at least one of the links;
- storing on a storage device of said access provider network information indicative of the traffic level for at least one of the links;
- and
- in response to a request from a user of the access provider network who wishes to access the destination address, transmitting said traffic level information to said user.
A traffic reporting system for a data communication network comprising:
- a computer which executes a daemon process to monitor traffic level on a plurality of links connecting an access provider network to a destination address of a data communications network by detecting occurrences of packet loss and measuring round trip transmission delay, on at least one of the links;
- a storage device of the access provider network on which information associated with the traffic level on at least one of the links is stored;
- and
- means for transmitting to a user the information associated with the traffic level on at least one of the links in response to a request from the user for accessing the destination address.
