Patent number: 8572434Abstract: Described are computer-based methods and apparatuses, including computer program products, for system health monitoring. Backup set metadata is received, wherein the backup set metadata comprises information about backup data sets that are received by a backup storage system. One or more processes that process the backup set metadata through an emulated processing flow path are executed, wherein the one or more processes are also implemented in the backup storage system. Two or more potential processing states are determined within the emulated processing flow path. A reason code is determined for each backup set metadata entry of the backup set metadata indicative of a reason that the backup set metadata entry is in a processing state of the two or more potential processing states. A problem with the manner in which the backup set metadata is flowing through the emulated processing flow path is identified based on the reason codes.Type: GrantFiled: September 29, 2010Date of Patent: October 29, 2013Assignee: Sepaton, Inc.Inventors: Jane Riegel, John Chernoch

Patent number: 8386850Abstract: Backup set metadata is received, wherein the backup set metadata comprises information about backup data sets that are received by a backup storage system that stores the backup data sets. The manner in which the backup data sets flow through a processing flow path of the backup storage system is emulated. One or more processes that process the backup set metadata through an emulated processing flow path are executed, wherein the emulated processing flow path is indicative of the manner in which the backup data sets flow through the processing flow path of the backup storage system when the backup storage system stores the backup data sets. One or more timing statistics are calculated based on the flow of the backup set metadata through the emulated processing flow path.Type: GrantFiled: September 29, 2010Date of Patent: February 26, 2013Assignee: Sepaton, Inc.Inventors: Jane Riegel, John Chernoch

Patent number: 7916757Abstract: A stack of network routers is composed of at least one (elected) master unit and one or more slave units each capable of running a routing protocol. Only the master unit runs the entire routing protocol at a given time. It forwards direct update messages via a transmission control protocol to each of the slave units. These direct update messages may include specific packet formats for the protocol state machinery where such machinery is required by the routing protocol, e.g., the interface state machine and the neighbor state machine for the OSPF protocol, and for the net databases, e.g. the link state databases for the OSPF protocol, in each of the slave units. Each slave unit may run its protocol state machinery (where provided) based purely on the direct update messages received from the master. The synchronisation of the net databases may be based on snooping net update packets and a comparison of the information received thereby with verification data messages sent from the master unit.Type: GrantFiled: December 8, 2008Date of Patent: March 29, 2011Assignee: Hewlett-Packard CompanyInventors: Jane A.

Patent number: 7274703Abstract: A network unit comprises a multiplicity of ports for transmitting and receiving data packets, a bridging facility and a routing facility. The network unit has a multiplicity of mutually exclusive states which includes an initial state from which said network unit can transition to either a slave state; or a waiting state from which in the absence of receipt from elsewhere of a broadcast advertisement including an advertised address corresponding to an address of the unit, the unit transitions to a master routing state in which the routing facility is enabled and the unit broadcasts a corresponding advertisement including an address of the unit. The unit transitions from the waiting state, when it receives from elsewhere (i.e., another unit) such a broadcast advertisement, to a master bridging state in which the routing facility is disabled and the unit provides commands for disabling a routing facility of other similar units to which the network is connected.Type: GrantFiled: July 16, 2002Date of Patent: September 25, 2007Assignee: 3Com CorporationInventors: Raphael J Weyman, Francisco Aquino, David Reinauer, Jacek A Tulacz, Jane A Riegel
