All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method for restricting access to network performance information associated with communications over a packet network, said method comprising:
receiving a request from a user to access network performance information associated with communications of data packets over a packet network;
accessing a permission table for determining whether the user has permission to access the network performance information, including retrieving an entity identifier for determining user type of the user, retrieving a segment identifier for determining a portion of the acket network in which the network performance information is accessible to the user, and retrieving a network performance information identifier for determining categories of the network performance information accessible to the user;
in response to determining that the user has permission to access the network performance information, enabling the user to access only the determined categories of the network performance information of the portion of the packet network in which the network performance information is accessible to the user; and
restricting the user from accessing the network performance information outside of the portion of the packet network in which the network performance information is accessible to the user and outside of the determined categories of the network performance information accessible to the user.
2. The method according to claim 1, wherein the segment identifier indicates that the portion of the packet network in which the network performance information is accessible to the user is limited to only those network segments between a customer’s CPE and a network access point.
3. The method according to claim 1, wherein the categories of the network performance information accessible to the user is limited to total bandwidth usage.
4. The method according to claim 1, wherein the categories of the network performance information accessible to the user is limited to network performance information associated with real-time data packets.
5. The method according to claim 1, wherein receiving the request from the user includes receiving the request at a central location on the packet network.
6. The method according to claim 1, wherein the categories of the network performance information accessible to the user is not limited.
7. A system for restricting access to network performance information associated with communications over a packet network, said system comprising:
a storage unit configured to store network performance information associated with communications of data packets over a packet network, and further configured to store a permission table indicating access permission to the network performance information;
an inputoutput (IO) unit configured to communicate with the packet network;
a processing unit in communication with said storage unit and said IO unit, said processing unit configured to:
receive a request from a user to access network performance information associated with communications of data packets over a packet network;
access the permission table to determine whether the user has permission to access the network performance information, including retrieving an entity identifier for determining user type of the user, retrieving a segment identifier for determining a portion of the packet network in which the network performance information is accessible to the user, and retrieving a network performance information identifier for determining categories of the network performance information accessible to the user; and
enable the user to access only the determined categories of the network performance information in response to determining that the user has permission to access the network performance information,
prevent the user from accessing the network performance information outside of the portion of the packet network in which the network performance information is accessible to the user and outside of the determined categories of the network performance information accessible to the user.
8. The system according to claim 7, wherein the segment identifier indicates that the portion of the packet network in which the network performance information is accessible to the user is limited to only those network segments between a customer’s CPE and a network access point.
