Routing mechanism for networks with separate upstream and downstream traffic
First Claim
1. An apparatus comprising:
- a network access server to receive upstream packets from a client, the server having a network access server port address;
an authentication server having an authentication server port address coupled to said network access server;
a routing manager having a routing manager port address coupled to said network access server and said authentication server;
wherein said routing manager is configured to;
(1) receive, on said routing manager port address, a set of accounting request packets from said network access server port address;
(2) parse said accounting request packet to derive a command flag;
(3) forward said set of accounting request packets to said authentication server port address; and
(4) generate a set of routing table modification commands for a network router based on said command flag, the network router to route downstream packets to the client.

Abstract
What is disclosed is a method having the first step of receiving, on a routing manager port address, a set of accounting request packets from a network access server having a network access server port address. Then, parsing the accounting request packet to derive a command flag and forwarding the set of accounting request packets to an authentication server, having an authentication server port address, over the authentication server port address. The method includes the further step of generating a set of routing table modification commands for a network router based on the command flag. What is also disclosed is an apparatus having a network access server, an authentication server coupled to the network access server, and a routing manager coupled to the network access server and the authentication server. The network access server has a network access server port address, the authentication server has an authentication server port address, and the routing manager has a routing manager port address. The routing manager is configured to: (1) receive, on the routing manager port address, a set of accounting request packets from the network access server port address; (2) parse the accounting request packet to derive a command flag; (3) forward the set of accounting request packets and to the authentication server port address; and (4) generate a set of routing table modification commands for a network router based on the command flag.

21. An article of manufacture comprising:
-
a machine-readable medium having instructions stored therein which, when executed by a set of processors, cause;
receiving, on a routing manager port address, a set of accounting request packets from a network access server having a network access server port address, the network access server to receive upstream packets from a client;
parsing said accounting request packet to derive a command flag;
forwarding said set of accounting request packets to an authentication server having an authentication server port address; and
generating a set of routing table modification commands for a network router based on said command flag, the network router to route downstream packets to the client. - View Dependent Claims (22, 23, 24, 25, 26)
