Abstract: Efficient error control techniques for TCP-based multicast networks are described. In one embodiment, for example, an apparatus may comprise at least one memory and logic for routing data at a node of a TCP multicast tree, at least a portion of the logic comprised in hardware coupled to the at least one memory, the logic to identify a data segment that has been retransmitted to the node from an adjacent upstream node, determine whether each of a plurality of adjacent downstream nodes have acknowledged at least one previous transmission of the data segment, and in response to a determination that one or more of the adjacent downstream nodes have not acknowledged at least one previous transmission of the data segment, forward the data segment to each of the one or more adjacent downstream nodes. Other embodiments are described and claimed.

Abstract: Examples can include buffering techniques for transmission control protocol (TCP) based multicast networks. Various devices in the multicast network can include buffering features to behave as a proxy for the source server, thereby splitting the network into multiple subdomains. Each subdomain could therefore independently provide error control for the TCP-based multicast network.

Abstract: A network device includes a network interface, monitoring circuitry, and a processor. The network interface is operative to couple the network device to a communications link and to exchange mail message data over the communications link. The monitoring circuitry is configured to monitor an operating state of the network device and to detect an alarm condition. The processor is operatively coupled to the network interface, the monitoring circuitry, and to a memory. The memory includes executable instructions for causing the processor to send a mail message to report a detected alarm condition when the monitoring circuitry detects the alarm condition. A method of reporting device status data includes detecting an alarm condition at a network device and sending a mail message to a recipient device to report the alarm condition.
