Abstract: A system and method for allocating an interval to each of multiple locations within a network topology, where each interval indicates a range of Internet Protocol (IP) addresses associated with the corresponding location. Each allocated interval is associated with a computing service that provides information about network services near the location associated with the allocated interval. The intervals are allocated into intermediate nodes, where each intermediate node includes at least two of the intervals. The intervals, associated computing services, and intermediate nodes are then organized into a modified B+ tree structure that facilitates the discovery of one of the network services near the allocated interval.

Abstract: The invention presented herein permits split-routing to occur without any changes, modifications, or configuration of the requesting host, network stacks, network architectures and routing and forwarding behavior. The invention is carried out by way of a Module that intercepts the normal and standard DHCP communication between a requesting device and a DHCP server, and substitutes the elements within the server response with the Module's own predefined elements. These substitute elements leverage the behavior of standard protocols to gain desired device network behavior.

Abstract: In a network, a user can configure host-level policies usable for load balancing traffic to servers of a domain. A global server load balancing (GSLB) switch provides load balancing to the servers, and is configured with the GSLB host-level policies. Users can define a host-level policy (alternatively or additionally to a globally applied GSLB policy) and apply the host-level policy to hosts in domains configured on the GSLB switch. Thus, the user can enable different policies for different hosts. This allows the user to have the flexibility to control metrics used for selection of a best address for querying clients, as well as the metric order and additional parameters used in the GSLB process, at the host level.

Abstract: Provided is a method of source discovery for non-flooding multicast using OpenFlow. A data packet is received from a source address on a network device. The data packet is routed from the network device to an OpenFlow controller. The OpenFlow controller identifies a rendezvous point (RP) of the network device, maps a random address to the source address in a port used for connecting with the rendezvous point (RP), generates a flow message containing a rule for handling the data packet, transmits the flow message to the network device and adds a flow entry in the network device based on the rule for handling the data packet.

Abstract: An application provides a “working elsewhere” status for users working at a location other than their regular work location and still available for meetings, communication sessions, etc. The application determines a user location being other than regular work location and the user still being available through user selection, information from user associated application(s), and/or from a presence notification. The application adjusts the user status to a working elsewhere status and makes the new status available to other applications such as calendaring, communication applications, presence service(s), and comparable ones. Meetings may be scheduled, communication sessions facilitated if the working elsewhere status is sufficient/acceptable for other users.

Abstract: A controller may help reduce network traffic that is associated with broadcasting of Dynamic Host Configuration Protocol (DHCP) packets by converting broadcast DHCP packets into unicast DHCP packets and forwarding the unicast DHCP packets to appropriate DHCP servers. The servers may be identified from a database of servers that is updated with DHCP server address information based on DHCP reply packets that are received by the controller from servers in the network. To convert DHCP request packets into unicast packets, the controller may modify address header fields of the packets such as Ethernet addresses and Internet Protocol (IP) addresses. The controller may forward the modified DHCP request packets to the server by providing packet forwarding rules such as flow table entries to the switches or by forwarding the modified DHCP request packets through the controller.

Abstract: In one embodiment, a connectivity verification protocol (CVP) session for a particular virtual interface (VI) may operate on a particular group of two or more line cards (LCs) on a network device. The group of LCs may then transmit CVP session packets, at a reduced rate that is sufficient to maintain the CVP session based on a negotiated CVP full rate, onto the particular VI through ingress path processing on the network device. Ingress path processing, in particular, takes transmitted CVP session packets and egresses them onto an appropriate LC of the network device currently responsible for the VI egress. Also, in response to receiving CVP session packets for the VI on an LC of the network device currently responsible for the VI ingress, the receiving LC may forward the received CVP session packets to the particular corresponding group of LCs, which may then process the received CVP session packets.

Abstract: A network node for communicating data packets secured with a security protocol over a communications network includes a host information handling system (IHS) and one or more external security offload devices coupled by a secure data link. The host IHS communicates state information about data packets, and the external offload security device provides stateless secure data encapsulation and decapsulation of packets using a security protocol. An external network interface controller or internal network interface controller communicates encapsulated data packets over the communications network to a final destination. Encapsulation and decapsulation of packets by the external security offload device reduces network latency and reduces the computational load on the processor in the host IHS. Maintaining state information in the host IHS allows hot-swapping of external security offload devices without information loss.

Abstract: Techniques are provided for using the mobility support features of IPv6 to allow client and server nodes to communicate without the continuing intervention of a load-balancing node that selected the server node. A load-balancing node intercepts a TCP SYN packet addressed to a virtual IP address. The load-balancing node selects a server node from among multiple server nodes, and sends the packet toward the server node. The server node sends an IPv6 packet toward the client node. The packet contains a Binding Update option that specifies the virtual IP address as a Home Address. This information causes the client node to replace destination addresses in outgoing IP packets so that packets that the client node would have sent toward the virtual IP address are sent toward the selected server node's IP address instead. Consequently, the IP packets are routed toward the selected server node instead of the load-balancing node.

Abstract: A parallel multiprocessor system includes a packet-switching communication network comprising a plurality of processor nodes operating concurrently in parallel. Each processor node generates messages to be sent simultaneously to a plurality of other processor nodes in the communication network. Each message is divided into a plurality of packets having a common destination processor node. Each processor node has an arbiter that determines an order in which to forward the packets onto the network toward their destination processor nodes and a network interface that sends the packets onto the network in accordance with the determined order. The determined order operates to substantially avoid sending consecutive packets from a given source processor node to a given destination processor node and to randomize the destination processor nodes of those packets presently traversing the communication network.

Abstract: A message distribution center (MDC) and Intelligent Delivery Agent are implemented in a wireless Internet gateway interposed between content providers and a wireless carrier to subjectively examine and direct messages via SMTP based on desired rules (e.g., non-peak hours, paying subscribers only, etc.) using standard SMTP Gateway and other well-known protocols. The MDC includes an individual queue for each subscriber, and the provider is informed through conventional SMTP protocol messages that the short message has been accepted. If the carrier has specifically disallowed service for a particular MIN (e.g., in the case of churning), then the content provider is informed through an SMTP interchange that the recipient is invalid. An MDC provides a single mechanism for interacting with subscribers of multiple carriers, regardless of each carrier's underlying infrastructure.

Abstract: In a communication system, using source address, source port number, destination address and destination port number, terminals A and B located behind NAT routers A and B, respectively, communicate with each other through the NAT routers A and B. A server SV which is not located behind any NAT routers identifies the NAT router A as a NAT router of a certain type which translates the source port number into a different source port number if the destination port number is changed. The server SV then guesses a port number obtained by adding (or subtracting) a value to (or from) the source port number used for transmission of data from the terminal A through the NAT router A as a port number of the terminal A in a case where the NAT router has been identified as the certain type, and informs the terminal B of the guessed port number.

Abstract: A new approach is proposed that contemplates systems and methods to support a hybrid solution that utilizes a centralized communication server as the main mechanism for communication between two clients (endpoints), but augments the server-based communication with an optional direct connection between the two clients whenever available while hiding the complexities and time spent dealing with the direct connection from the clients. The switch of the communication mode between the clients is kept transparent to them during their communication session without causing any inconvenience and/or disruption of the communication. When a direct endpoint to endpoint connection is not available the approach preserves the advantages of connecting through the intermediate communication server.
