Abstract
A method for routing packets sent from a user to the internet is provided for systems in which the user is connected to a private network. The method includes: extracting a source network address from the packet; using said source network address to retrieve a user profile for the user; examining said user profile to determine whether to route the packet through the private network or to route the packet directly to the Internet; and routing said packet according to said profile. This allows a user or network provider to choose whether to route packets destined for the Internet directly to the Internet rather than through the private network, thus preventing excessive network traffic on the private network.
Claims15
A method comprising:
- determining whether a device has logged on to a gateway having connections to a private network and to an Internet, wherein a user profile is associated with the device;
- and
- routing a packet according to a global flag, the global flag indicating whether to route the packet to the Internet directly or through the private network, the packet sent from the device to the Internet.
A program storage device readable by a computer, tangibly embodying a program of instructions executable by the computer to perform a method, the method comprising:
- determining whether a device has logged on to a gateway having connections to a private network and to an Internet, wherein a user profile is associated with the device;
- and
- routing a packet according to a global flag, the global flag indicating whether to route the packet to the Internet directly or through the private network, the packet sent from the device to the Internet.
An apparatus comprising:
- means for determining whether a device has logged on to a gateway having connections to a private network and to an Internet, wherein a user profile is associated with the device;
- and
- means for routing a packet according to a global flag the global flag indicating whether to route the packet to the Internet directly or through the private network, the packet sent from the device to the Internet.
An apparatus for routing a packet sent from a device to the Internet, the device connected to a private network, including:
- a global flag examiner configured to examine a global flag to determine whether to route the packet through the private network or to route the packet directly to the Internet if the device has not logged on to a gateway device having connections to the private network and to the Internet, wherein a user profile is associated with the device, and the packet is routed according to the global flag if the device has not logged on to the gateway device.
A network device apparatus for routing comprising:
- an input interface;
- an output interface;
- a processor which executes instructions that cause the processor to:
- determining whether a device has logged on to a gateway having connections to a private network and to an Internet, wherein a user profile is associated with the device;
- and
- routing a packet according to a global flag, the global flag indicating whether to route the packet to the Internet directly or through the private network, the packet sent from the device to the Internet.
