Abstract: A method resolves collisions in a networking system that includes a plurality of entities operable to transmit an intention to reserve a resource. A first request to reserve resources, which includes a listing of the resources along the first transmission path and a first intention priority value, is broadcast through the networking system.

The collision is resolved by comparing the first intention priority value to the second intention priority value. If the collision is resolved in favor of the first request, data is routed through the networking system using the resources along the first transmission path.

Abstract: A method and integrated hardware system for multicast transmission shaping in EPONs which employs a selective multicast algorithm that significantly reduces the complexity of traffic shaping for multicast traffic. Unlike prior art methods, my method exploits the broadcasting nature of the downstream point-to-multipoint access system including EPONs. Operationally, the method transforms a multicast traffic shaping problem into a unicast traffic shaping problem by selecting a multicast subscriber and subsequently treating packets addressed to that selected multicast subscriber as unicast. Advantageously, these packets are still available to other members of the multicast group. And since these packets are treated as unicast from the perspective of traffic shaping, my inventive method significantly reduces traffic shaping complexity in multicast environment.

Abstract: A flexible mechanism for routers to select the egress point for each destination prefix, herein referred to as tunable inter-domain egress (TIE) selection, comprises the step of ranking possible points of egress according to a metric, allowing network administrators to satisfy diverse goals, such as traffic engineering and robustness to equipment failures. A weighting function is discussed whereby known hot potato routing can be weighted against a fixed ranking scheme. TIE has been applied to data of two different autonomous systems posing different problems solved using integer-programming and multi-commodity flow techniques, respectively, to tune the TIE according to the weighting function to satisfy network-wide objectives. Experiments with traffic, topology and routing data from two different backbone networks demonstrate that TIE is both simple (for the routers) and expressive (for the network administrators) and can be practically applied in traffic engineering.

Abstract: A mobile router and a correspondent router, each configured for routing services for nodes within their routing prefixes associated with their respective routing tables, establish a secure, bidirectional tunnel based on a messaging protocol between each other and a route server resource. A reactive (i.e., on-demand) protocol is used that enables the requesting device (e.g, the mobile router, correspondent router), to obtain routing information in a secure manner from the route server. The mobile router sends a query via its home agent to the route server resource to identify the correspondent router serving the correspondent node. The mobile router sends a binding update request, specifying a home address and care-of address for the mobile router, to the correspondent router for establishment of a bidirectional tunnel. The correspondent router establishes the bidirectional tunnel, and updates its routing tables based on information from the route server resource.

Abstract: An apparatus for protecting legitimate traffic from DoS and DDoS attacks has a high-priority (505) and a low-priority (506) queue. Besides, a queue information table (402) has STT (Source-based Traffic Trunk) service queue information of a specific packet. A queue coordinator (502) updates the queue information table (502) based on a load of a provided STT and a load of the high-priority queue (505). A packet classifier (504) receives a packet from the network access unit (508), investigates an STT service queue of the packet from the queue information table (502), selectively transfers the packet to the high-priority (505) or the low-priority (506) queue and provides information on the packet to the queue coordinator (503). A buffer (507) buffers outputs of the high-priority (505) and the low-priority (506) queue and provides outputs to the network (509) to be protected.

One technique inputs a stream of messages, writes sequential sets of message parameters into a first FIFO at an entry point; reads the parameters from an exit point; and writes the read parameters into a second data structure. Importantly in this technique the entry point and the exit point are separated by predetermined minimum length defined in terms of a number of the sets of parameters and/or a time. Some preferred implementations also include a last value data store or bucket to store one or more most recent previous values of message parameters.

Abstract: Methods, systems, apparatus, and computer-readable media are provided for utilizing an alternate video buffer for console redirection in a headless computer system. According to the method, a buffer is created in the main memory of the computer that is configured to store character and attribute data for a display of the computer. When a video services software interrupt is detected, the interrupt is trapped. A determination is then made as to whether a function associated with the interrupt is for writing to a video display memory. If the function is for writing, the contents of the buffer are updated with the character or attribute information specified by the function. Data representing the updated character or attribute is then redirected to the remote computing device. If a read function is encountered, character or attribute information is retrieved from the buffer at a specified location and is returned in response to the function call.
