Abstract: Methods and apparatuses for a network element having DHCP proxy functionality are described. According to one embodiment, an exemplary method includes receiving, at a network element, a request for an IP address from a subscriber, in response to the request, on behalf of the subscriber, communicating with one or more IP address providers over a network to process the request, and responding to the subscriber with respect to the request as if the network element is an IP address provider, on behalf of the one or more IP address providers.

Abstract: In one embodiment, a method comprises receiving a request to modify a subscriber connection to a network element. The method also includes modifying attributes of the subscriber connection, within a memory of the network element, without disconnecting the subscriber connection from the network element.

Abstract: Techniques for minimizing packet loss of multicast traffic stream when a failure occurs are described herein. In one embodiment of the invention, a network element separately joins a multicast group through a first and second path respectively. During uninterrupted operation, the network element processes the packets of the multicast traffic stream it receives through the first path and drops the packets of the equivalent multicast traffic stream it receives through the second path. Upon an interruption of the packets of the multicast traffic stream being received through the first path, the network element transitions to processing the packets of the equivalent multicast traffic stream it receives through the second path. Other methods and apparatuses are also described.

Abstract: A database server stores in a subscriber record one or more attributes of an active subscriber connection coupling a computing device associated with the subscriber, including a data rate attribute. The database server receives a request to modify one or more of the attributes of the active subscriber connection including at least to modify the data rate attribute. The database server modifies the at least one of the attributes including modifying at least the data rate attribute and transmits the at least one modified attribute including at least the modified data rate attribute for the active subscriber connection to the network element to cause the network element to modify a corresponding attribute without disconnecting the subscriber connection from the network element.

Abstract: Techniques for providing resilient multicast traffic processing in a network element are described herein. In one embodiment of the invention, a network element separately joins equivalent multicast traffic streams at a first and second interface respectively. During uninterrupted operation, the network element processes the packets of the multicast traffic stream it receives at the first interface and drops the packets of the equivalent multicast traffic stream it receives at the second interface. Upon an interruption of the packets of the multicast traffic stream being received at the first interface, the network element transitions to processing the packets of the equivalent multicast traffic stream it receives at the second interface. Other methods and apparatuses are also described.

Abstract: A network element modifying the DHCP lease timer is described. According to one embodiment, an exemplary method includes maintaining, at a network element, DHCP lease time for one or more clients and in response to a DHCP renewal request from a client, on behalf of a DHCP server, providing DHCP renewal services to the client based on lease time information associated with the client without invoking the DHCP server.
