Abstract
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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
148 words
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.
Claim 2
Independent Claim
148 words
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.
Claim 3
Dependent Claim
33 words
The method of claim 1 wherein the network includes a plurality of destination sites of interest and comprises the step of repeating steps a), b), and c) for each destination site of interest.
Claim 4
Dependent Claim
24 words
The method of claim 2 comprising the step of prompting a user to submit a request for a level of activity of said network.
Claim 5
Dependent Claim
19 words
The method of claim 3 wherein said step of prompting includes providing a menu of destination sites of interest.
Claim 6
Dependent Claim
21 words
The method of claim 4 comprising the step of customizing the menu of destination sites of interest based on user preferences.
Claim 7
Dependent Claim
30 words
The method of claim 1 comprising the further steps of: analyzing said transit characteristics information to determine historical activity level; storing said historical activity levels for access by network users.
Claim 8
Independent Claim
128 words
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.
Claim 9
Independent Claim
128 words
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.
Claim 10
Dependent Claim
38 words
The method of claim 7 wherein said transmitting step further includes the step of: sending to said user data identifying at least one of said data communications networks as a source of traffic congestion to said destination address.
Claim 11
Dependent Claim
46 words
The method of claim 7 wherein said transmitting step further includes the step of: sending to at least one of said data communications networks a message indicating that at least one of said data communications networks is a source of traffic congestion to said destination address.
Claim 12
Dependent Claim
118 words
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.
Claim 13
Dependent Claim
118 words
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.
