20090307338 | Network Element Having a DHCP Lease Timer - 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. | 12-10-2009 |
20110246664 | DYNAMIC MODIFICATION OF A SUBSCRIBER CONNECTION - 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. | 10-06-2011 |
20130060891 | DHCP PROXY IN A SUBSCRIBER ENVIRONMENT - 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. | 03-07-2013 |
20130086233 | DYNAMIC MODIFICATION OF A SUBSCRIBER CONNECTION - 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. | 04-04-2013 |

20090113070 | ENHANCE FAULT TRACING IN MULTI-TIERED ETHERNET/MPLS NETWORK - Techniques for providing connectivity fault management (CFM) for a multi-tiered network are described herein. In one embodiment, a link trace message (LTM) is received at a provider edge (PE) router and originated from a first Ethernet node and destined to a second Ethernet node, where the PE router interfaces an Ethernet and a multi-protocol label switching (MPLS) network. In response, the PE router initiates an MPLS trace session, including generating an MPLS trace message based on the LTM message to one or more MPLS nodes along a path between the first and second Ethernet nodes within the MPLS network. Subsequently, in response to one or more MPLS trace reply messages from the MPLS nodes of the MPLS network, the PE router generates a first link trace reply (LTR) message and sends the first LTR message to the first Ethernet node over the Ethernet. Other methods and apparatuses are also described. | 04-30-2009 |
20090141740 | MULTIPLE PROTOCOL CROSS LAYER CUSTOMIZED QoS PROPAGATION AND MAPPING - Techniques for multiple protocol cross layer customized QoS propagation and mapping are described herein. In one embodiment of the invention, a first QoS code of a packet is determined, the packet having a first encapsulation layer and a second encapsulation layer, the first QoS code being included within the first encapsulation of the packet. From application of a first cross layer QoS map to the first QoS code, determining that the second encapsulation layer of the packet should be used in determining a QoS classification. The reference point to the second encapsulation layer is stored. The QoS classification is determined with use of the reference point. A representation of the QoS classification is stored in a QoS descriptor and the QoS descriptor is used to influence processing of the packet. Other methods and apparatuses are also described. | 06-04-2009 |
20090245248 | METHOD AND APPARATUS FOR PROVIDING RESILIENCY IN MULTICAST NETWORKS - 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. | 10-01-2009 |
