Abstract:

A system for reliable multicast transmission [multicasting data packets] in a packet-based data network includes mechanisms for performing the following: (1) preparing at least one packet comprising a payload portion and multicast route information, an error detection mechanism; (2) transmitting the packet to at least one intermediate node for delivery to at least two destination nodes; (3) waiting for a period of time for at least one acknowledgment signal indicating receipt of the at least one packet by at least one destination node; and (4) retransmitting a packet to a set of destination nodes from which no positive acknowledgment has been received. The multicast routing information includes information for use by the at least one intermediate node to forward the packet to at least two destination nodes.

International Classification:

G06F 15173

US Classification:

709238, 709203

Abstract:

A method for multicasting data packets includes the steps of preparing at least one packet at a source node and transmitting the packet to at least one intermediate node. The packet includes a payload portion and multicast route information. The multicast route information includes information for use by the intermediate node to forward the packet to at least two destination nodes. According to another aspect of the invention, a method for multicasting data packets in a packet-based data network includes the step of transmitting an Internet Protocol (âIPâ) packet from a source node to a first node. The IP packet includes an IP header and an IP payload containing an encapsulated multicast (EM) datagram, the EM datagram comprising an EM header and an EM payload. The EM header includes multicast routing information instructing the first node to transmit the EM payload to at least two second and third nodes. According to another embodiment, a system including various network nodes is adapted to implement the described method.

Richard Harold Boivie - Monroe CT

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H04J 1402

US Classification:

359128

Abstract:

An optical switch for a network having a plurality of nodes, includes a switch coupled to communications links used for input and output in which a plurality of wavelengths are used to carry traffic on a communications link, and a controller, coupled to the switch, for controlling the operation of the switch by implementing a routing protocol, and implementing a labeling protocol to associate a wavelength with a route table destination. The controller controls the switch to direct the various wavelengths of traffic from an input link to an appropriate output link as determined by the routing protocol and the labeling protocol.

US Classification:

714749, 370400, 370432, 709200

Abstract:

A multicast communication system for small groups using a protocol to indicate to routers receiving a packet according to the protocol to perform the following process: (1) determining a next hop for each of the destination nodes listed in the packet received; (2) partitioning the destination nodes into groups according to the next hop determined for each destination node in the preceding step; (3) replicating the packet such that there is at least one copy of the packet for each of the next hops; (4) modifying the list of addresses for the destination nodes such that the list of addresses for each of the next hops includes only the addresses for the destination nodes to be routed in that next hop; and (5) transmitting the modified copies of the packet to the next hops found in the previous steps for routing to the addresses included in each packet.

US Classification:

709225, 709232, 370235

Abstract:

A method and system for controlling and guaranteeing a service level agreement (SLA) based on a communications outbound link bandwidth usage to a plurality of customers having electronic business activity hosted by at least one server as a server farm, includes monitoring the outbound communications bandwidth usage by each customer traffic to determine a level of service being provided to each customer with respect to the agreed service level agreement in each service cycle time per unit of time. The flow of incoming requests to each customer business activity application is controlled so as to guarantee a level of service previously agreed to the customer by queuing requests to the customer and by selectively dropping requests to the customer to guarantee the agreed service levels to the customer. The controlling process controls and guarantees each outbound link usage based service level agreement by controlling the flow of incoming requests to the at least one server.

Abstract:

A method for distributing web content efficiently across a network preferably using multicast transmission techniques. An information server receives a first request for a portion of information from a first networked device. It then receives a second request for the portion of information from a second networked device. The information server collects the first request and the second request into a bucket. The information server creates a combined response, destined for reception by the first networked device and the second networked device, and then provides the combined response including the portion of information requested by both the first and second networked devices, to a network interface.

US Classification:

Abstract:

An Internet communication technique is provided for making efficient use of available bandwidth between network points by analyzing responses to received requests for information items to identify multiple responses that include the same item and optionally that also have a common next hop address, and responding to the multiple requests with a combined packet addressed to multiple addresses. The combined packets include sufficient information from which to generate reliable unicast packets, that will ultimately be formed from the contents of the combined packet. The combined packet is received by a network router identified by a common next hop address, and a sequence of addresses are associated in sub-groups corresponding to common next hop addresses. A plurality of packets are generated based on the combined packet, each of which includes addresses that correspond to destinations that share a common next hop address. The plurality of packets are then sent to their corresponding next hop addresses.
