초록 ▼

A method for maintaining Quality of Service for communication network subscribers regardless of their log-on location is disclosed. For one embodiment the communications network has a first access point having a first router and a local memory containing at least one user profile containing a subscriber's pool identifier, and a second access point having a second router configured to provide a forwarding rate based on a source address from each of said packets. A service type for a subscriber is defined. A pool identifier corresponding to a service level agreement is assigned to the subscriber. If the subscriber attempts to log-on to the second access point, the subscriber's pool identifier is obtained from a global memory available to the second access point. The pool identifier is used to select a source address. A packet sent by the subscriber is forwarded using the second router, each packet containing the source address.

대표청구항 ▼

We claim: 1. A method of maintaining Quality of Service for subscribers belonging to a communications network regardless of the log-on location of the subscribers, the communications network having a first access point having a first router and a local memory containing at least one user profile containing a subscriber's pool identifier, and a second access point having a second router configured to provide a forwarding rate based on a source address from each of the packets, the method comprising: defining a service type for a subscriber belonging to the communications network; assigning a pool identifier to the subscriber, the pool identifier corresponding to a service level agreement; and obtaining, if the subscriber attempts to log-on to the second access point, the subscriber's pool identifier from a global memory which is available to the second access point, using the pool identifier to select a source address, forwarding a packet sent by the subscriber using the second router, each the packet containing the source address. 2. The method of claim 1, further including: providing addresses in an address pool; categorizing the addresses into groups which represent a service type for subscribers belonging to the communications network; and allocating to the subscribers user profiles which include pool ids that correspond to the service type. 3. An apparatus for maintaining Quality of Service for subscribers belonging to a communications network regardless of the log-on location of the subscribers, the communications network having a first access point having a first router and a local memory containing at least one user profile containing a subscriber's pool identifier, and a second access point having a second router configured to provide a forwarding rate based on a source address from each of the packets, the apparatus comprising: means for defining a service type for a subscriber belonging to the communications network; means for assigning a pool identifier to the subscriber, the pool identifier corresponding to a service level agreement; and means for obtaining, if the subscriber attempts to log-on to the second access point, the subscriber's pool identifier from a global memory which is available to the second access point, using the pool identifier to select a source address, forwarding a packet sent by the subscriber using the second router, the packet containing the source address. 4. The apparatus of claim 3, further including: means for providing addresses in an address pool; means for categorizing the addresses into groups which represent a service type for subscribers belonging to the communications network; and means for allocating to the subscribers user profiles which include pool ids that correspond to the service type. 5. A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform a method for maintaining Quality of Service for subscribers belonging to a communications network regardless of the log-on location of the subscribers, the communications network having a first access point having a first router and a local memory containing at least one user profile containing a subscriber's pool identifier, and a second access point having a second router configured to provide a forwarding rate based on a source address from each of the packets, the method comprising: defining a service type for a subscriber belonging to the communications network; assigning a pool identifier to the subscriber, the pool identifier corresponding to a service level agreement; and obtaining, if the subscriber attempts to log-on to the second access point, the subscriber's pool identifier from a global memory which is available to the second access point, using the pool identifier to select a source address, forwarding a packet sent by the subscriber using the second router, the packet containing the source address.
