摘要： A method is provided for preventing denial-of-service attacks on hosts attached to a subnet, where the attacks are initiated by a remote node over an external network. The method is performed by a router which forwards packets between the external network and the subnet. The router receives a packet for forwarding to a destination address in an address space of the subnet according to the IPv6 protocol and looks up the destination address in a Neighbor Discovery (ND) table. The ND table is populated by operations on the subnet that were completed prior to receipt of the packet. Entries in the ND table store address information of the hosts that have been verified by the router to be active. The router forwards the packet to the destination address if the destination address is stored in the ND table. Otherwise, the packet is discarded.

摘要： A method performed by a slave network edge node (e.g., a Broadband Network Gateway BNG2) for enhancing a Long Term Evolution (LTE) backup channel in the event of a failure of a master network edge node (e.g., BNG1) in a wireline network. When BNG2 detects the failure of BNG1, BNG2 sends a failure update message to a Packet Data Network Gateway (PDN GW) of an LTE network. The PDN GW provides a backup channel for the CPE to reach the wide area network over a mobile tunnel. Before the failure the mobile tunnel has an end point at BNG1, and the failure update message notifies the PDN GW that the end point of the mobile tunnel has changed from BNG1 to BNG2. After BNG2 receives a failure acknowledgement message from the PDN GW, BNG2 routes the traffic from the PDN GW over the mobile tunnel to the wide area network.

摘要： A network element and process determines and configures capabilities of network element components. The network element components include a set of control elements where the set of control elements determine capabilities of each of a set of forwarding elements. The method includes initiating communication with a forwarding element in the set of forwarding elements by a control element. The control element requests that the forwarding element to provide a set of logical function block identifiers of supported logical function blocks for the forwarding element. The set of logical function block identifiers is then received from the forwarding element in response to the request. The set of logical function block identifiers are matched with known forwarding element capabilities to determine capabilities of the forwarding element. A forwarding element capability model is then updated with the capabilities of the forwarding element.

摘要： A method to provide load balancing and routing for a plurality of end systems in a network. The network contains a load balancer (LB) and the method comprises receiving a request packet with Internet Protocol version 6 (IPv6) addresses specified. A destination address is associated with a set of target end systems and presence of a nonce information indicates the requesting correspondent node is Identifier Locator Network Protocol (ILNP) capable. The method further comprises directing the request packet to a specific end system from the set of target end systems that share a load balanced address, wherein each target end system has a unique direct path locator prefix. The method also comprises overwriting a common IPv6 locator prefix with the unique direct path locator prefix, forwarding the request packet to the specific end system, and notifying a requesting correspondent node the direct path locator prefix for the specific end system.

摘要： A process is performed by a controller in a split-architecture network. The controller monitors congestion of traffic groups across the split-architecture network and executes the process to provide delay based data rate control to alleviate congestion of the traffic groups. The process includes configuring an ingress switch and egress switch for each traffic group to collect delay measurement data for data packets of each traffic group as they arrive at the ingress switch and egress switch. The delay measurement data is received from the ingress switch and egress switch of each traffic group. A check is made whether a minimum data packet delay for any traffic group exceeds a defined threshold value. A throttling rate is calculated for each traffic group in the split-architecture network, in response to the defined threshold value being exceeded.

摘要： A system and method for chaining one or more services in a service provider network. A service chaining policy and associated Service Path Identifier (SPID) are determined at an ingress node with respect to a particular data packet flow. If the service chaining policy involves one or more service nodes to be traversed by the data packet flow, each service node's EIDs and RLOCs are determined. A sequential data exchange process with the service nodes is effectuated using encapsulation of data packets based on the EIDs and RLOCs for obtaining services in accordance with the order of services set forth in the chaining policy.

摘要： A method is implemented in a network element of a service network. The network element executes a packet processing element (PPE) of a plurality of PPEs, where each PPE in the plurality of PPEs executes a stage of packet processing for the service network and where the plurality of PPEs are connected to one another by a plurality of switch fabrics. The PPEs self-select a subset of a set of equivalent service chains to service with each service chain defining a subset and sequence of the plurality of PPEs. Each PPE self-selects the subset of equivalent service chains to process based upon knowledge of the plurality of PPEs servicing that stage of the full set of service chains such that there is spreading of load across all available PPEs in that stage. There is no single point of failure and minimal reassignment of PPEs for a set of equivalent data flows traversing the plurality of PPEs of the service network for changes in topography of the plurality of PPEs in the service network.

摘要： In response to a Mobile Access Router (MAR) initially attaching to a Multi-Protocol Label Switching (MPLS) domain through a first Access Router (AR) in the domain, a Mobility Anchor Point (MAP) in the MPLS domain establishes a plurality of Label Switched Paths (LSPs) for the MAR. For example, the MAP establishes an active LSP to the MAR through the AR to which the MAR has initially attached, and further establishes an inactive LSP for the MAR to each of one or more other ARs in the MPLS domain. An inactive LSP established at a given AR for a given MAR is activated when/if that MAR attaches to the AR. Correspondingly, the present invention includes method and apparatus teachings related to the MAP, ARs and the MAR, as regards establishing inactive LSPs, activating inactive LSPs, and extending an activated LSP to the MAR.
