Abstract: In the present solution, when a cluster node sends an ARP request for an external IP, the node sends a message to all the other nodes, which are part of the CLAG to expect an ARP reply for the IP. When a node in the cluster receives the ARP reply, the node informs the other nodes which are part of the same CLAG to update the MAC address. Also when an ARP entry is learned/updated over a CLAG link as part of an ARP request/Gratuitous ARP, the node learning/updating the ARP entry will inform other nodes which are part of the same CLAG about the learned/updated ARP entry. Nodes in a cluster may communicate between with each other over a dedicated backplane, which may be a separate physical medium.

The unauthenticated user is allowed to control the security system based on the determination that the unauthenticated user is the authorized user.

Abstract: A digital security threat management system is disclosed. The system detects the presence of a computing system, on a network, that has been compromised by an undetected and/or unknown digital security threat. The digital security threat management system recognizes characteristic emanations from a computer system that has been compromised. Because the characteristic emanations that result from a known threat can be the same as the characteristic emanations that result from an undetected and/or unknown threat, the digital security threat management system can learn to detect a computing system that has been compromised by an unknown threat if the security threat management system recognizes characteristic emanations from a previous attack, based on a known threat, of the computing system. In this way, the system can detect the presence of a compromised computing system, even if the cause of the compromise remains undetected and/or unknown. Appropriate remedial action may be taken upon detection.

Abstract: Content delivery to end user devices (EUD) is controlled by transmitting content portions at a controlled flow. The time for the EUD to process the data is used to control the flow. The first portion is transmitted to the EUD and the amount of time to process the first portion is noted. Threshold values to stop and start transmissions are examined prior to the transmission of each content portion. If the amount of data remaining to be processed by the EUD is below the stop transmission threshold, transmission continues with the next portion. If the amount of data remaining to be processed by the EUD is above the stop threshold, transmission is either stopped or retarded. When it is determined that the amount of data remaining to be processed by the EUD is above the start transmission threshold, transmission is started or continued.

Abstract: An apparatus and method for extending the scalability and improving the partitionability of networks that contain all-to-all links for transporting packet traffic from a source endpoint to a destination endpoint with low per-endpoint (per-server) cost and a small number of hops. An all-to-all wiring in the baseline topology is decomposed into smaller all-to-all components in which each smaller all-to-all connection is replaced with star topology by using global switches. Stacking multiple copies of the star topology baseline network creates a multi-planed switching topology for transporting packet traffic. Point-to-point unified stacking method using global switch wiring methods connects multiple planes of a baseline topology by using the global switches to create a large network size with a low number of hops, i.e., low network latency. Grouped unified stacking method increases the scalability (network size) of a stacked topology.

The initial buffer size may be determined and modified based on a maximum initial buffer size, and the maximum initial buffer size may be determined based on delays associated with storing data to the buffer.

The maximum acceptable buffering delay may be identified by determining drop rates associated with different buffering delays and selecting, as the maximum acceptable buffering delay, one of the buffering delays associated with a maximum acceptable drop rate.
