Abstract: Methods and systems for managing resources in a storage system are provided. As an example, one method includes determining a maximum node utilization of a first node operating in a networked storage environment for storing information at a plurality of storage devices, where the maximum node utilization is based on a first factor that tracks utilization of a processor of the first node; comparing the maximum node utilization to a first threshold value; and triggering an event when the maximum node utilization has reached the first threshold value.

Abstract: In an embodiment, a server computer comprises service processing logic that implements a Multi Step Retry Reinitialization Protocol Flow, and a protocol-aware rate limiting unit configured to cause one or more processors to perform receiving a message from a client; determining whether the received client message is a start type of message that requests starting the Flow; in response to determining that the received client message is a start type of message, determining whether to provide the received client message to the service processing logic using a discriminating rate limiting process. As a result, service unavailability may be prevented by rate limiting start types of messages, thereby allowing services to finish processing in-process protocol flows, when large numbers of clients concurrently attempt to obtain the services.

Abstract: A hybrid fiber coaxial (HFC) access network manager is formed to include a mediated access system to control each service provider's ability to monitor, view and re-configure selected elements within the HFC access network. A database included within the manager contains a mapping between the information service providers and the various network elements for which each service provider is permitted access and/or control. With mediated access, an information service provider has the ability to monitor quality, perform diagnostic tests and configure that equipment which directly supports the provided services.

Abstract: A hybrid fiber coaxial (HFC) access network manager is formed to support a variety of functions related to the operation and management of an HCF access plant. The HFC access network manager allows for monitoring of the downstream and upstream transmission paths, and supports the sectionalization of faults. The monitoring can be achieved through a variety of techniques including, but not limited to, monitoring bit error rate (BER), frame error rate (FER), carrier-to-noise ratio (C/N), or any other suitable quality-related signal parameter.

Abstract: A hybrid fiber coaxial (HFC) access network manager is formed to support a variety of functions related to the operation and management of an HCF access plant. The network manager includes a topology discovery module that can function either automatically, or under control of a command from the access network manager, to poll individual network elements to identify their type and location, thus creating a topological map of the network. The polling can be accomplished in either the analog or digital domain.

Abstract: A monitoring system for a HFC network includes a plurality of “test points” disposed at various locations throughout the network. Each test point is used to allow for the isolation of communication problems within the network (for example, ingress) and mitigation of the effects of the network problems. By distributing a plurality of test points throughout the topology of the network, only limited sections of the network need to be isolated at any point in time to address the particular communication problem.
