RSS rtoVirtualizing Storage for VMware Success
White Paper Reduce VMware RTO to minutes Server virtualization has made day-to-day life a whole lot simpler for systems administrators; however, the benefits have not been shared by storage administrators and backup operators, who face new challenges as the... [24 Jul 2008]
Economical Disk-Based Recovery for the High-End: New Space Saving Pointer-Based Snapshots
White Paper This paper discusses these new solutions with respect to three key criteria: economics, recovery point objectives (RPO), the difference between current time and the most recent backup, and recovery time objectives (RTO), how quickly data can be... [03 Jul 2008]
On Retransmission Schemes for Real-time Streaming in the Internet
White Paper This paper presents a trace-driven simulation study of three classes of retransmission timeout (RTO) estimators in the context of low-bitrate real-time streaming over the Internet. In such applications, real-time RTO estimation plays a major role... [03 Jul 2008]
DR Checklist: 10 Reasons Why Your DR Plan May Fail
White Paper The Disaster Recovery (DR) vision is a scenario in which all disasters are withstood; using a well-crafted plan, operations are transferred to a remote facility to get the organization back online within Recovery Time Objective (RTO) and Recovery... [10 Apr 2008]
Terminal Server Performance Tuning
White Paper Whether you're experiencing slow logons, random pauses, or you'd just like accommodate more users on your server, this paper is your real-world field guide to techniques that will identify, troubleshoot, and resolve performance issues of Terminal... [25 Mar 2008]
Integrating Desktop Applications for Power System Restoration Drills
White Paper The Midwest ISO (MISO), the Regional Transmission Operator (RTO) for much of central North America, facilitates an annual Power System Restoration Drill. The drill has more than 700 participants from the MISO's member companies, neighboring RTO's... [20 Mar 2008]
Optimal Tuning of the TCP Retransmission TimeOut for Small-BDP Lossy Wireless Networks
White Paper Based on the system load and the average queue size of the packets waiting for transmission, it shows how an optimal value of the Retransmission TimeOut (RTO) can be chosen. The study discussed in this paper tells about TCP performance over small... [15 Jan 2008]
Attacking Unnecessary TCP Retransmits Due to Delay Spikes & Reordering (Eifel, F-RTO, DSACK-Based Approaches)
White Paper This paper introduces algorithms like Eifel, F-RTO and DSACK which aim to improve TCP performance. Spurious TCP Retransmission TimeOuts (RTOs) have been reported to be a problem on network paths involving links that are prone to sudden delays due... [15 Jan 2008]
On Estimating End-to-End Network Path Properties
White Paper The paper considers two basic transport estimation problems: determining the setting of the Retransmission Timer (RTO) for a reliable protocol, and estimating the bandwidth available to a connection as it begins. [15 Jan 2008]
Oracle Secure Backup 10.2 Policy-Based Backup Management
White Paper Reliable data protection in the enterprise extends beyond simple tape backup to multi-tiered data protection strategies based on criticality of data, Recovery Time Objectives (RTO) and retention meeting business and regulatory requirements. [09 Jan 2008]
Defending Against Low-Rate TCP Attacks: Dynamic Detection and Protection
White Paper The low-rate TCP attack is essentially a periodic short burst which exploits the homogeneity of the minimum Retransmission Time Out (RTO) of TCP flows and forces all affected TCP flows to back off and enter the retransmission timeout state. [09 Jan 2008]
TCP Adaptive RTO to Improve TCP Performance in Mobile Ad Hoc Networks
White Paper This paper proposes a new mechanism called TCP Adaptive RTO (TCP AR) that improves TCP performance in mobile ad hoc network s. TCP AR distinguishes routes failures from network congestion and adapts the RTO's value to network conditions. [27 Dec 2007]
Optimizing TCP Retransmission Timeout
White Paper The goal is to find a Retransmission Timeout (RTO) value that balances the throughput degradation between both of these cases. In the current TCP implementations, RTO is a function of the Round Trip Time (RTT) alone. [27 Dec 2007]
A Passive State-Machine Approach for Accurate Analysis of TCP Out-of-Sequence Segments
White Paper One of the crucial factors that limit the accuracy of prior tools is that these do not incorporate variations across TCP implementations (for different operating systems) that have different parameters (e.g.timer granularity, minimum RTO... [20 Dec 2007]
Disaster Planning: How Fast Can You Recover from a Hurricane, Tornado, or Other Calamity?
White Paper How you can meet your recovery time and recovery point objectives (RTO/RPO) following a disaster Organizations hard hit by hurricanes, floods, or other catastrophes often discover too late that their disaster planning and recovery procedures didn't... [13 Dec 2007]
