April 2008-
Since many years, in most of all industries, traceability is essential, and very often is mandated by the State. Besides, since Sarbanes&Oxley act, traceability is mandatory for the information systems bound to financial transactions of a company quoted on stock market. In most of our systems, traceability is done with logs which provide the history of all transactions. But for networking, it seems that traceability is unknown. Firstly, what is traceability ....
Next Generation IT Event & Fault Management - Why a new architecture is so important.
[ Source: Rivermuse ]
November 2009-
The technical architectures of legacy network management platforms have not evolved significantly since their introduction nearly two decades ago.
With the rapid adoption of dynamically changing environments such as virtualized servers, MPLS networks and service-oriented architectures, the need for change is long overdue.
This white paper explores a new approach to IT event and fault management that will bring long awaited flexibility and agility to IT operations. Download this free whitepaper ....
Effectiveness of Loss Labeling in Improving TCP Performance in Wired/Wireless Networks
[ Source: Boston University ]
January 2008-
The Transmission Control Protocol (TCP) has been the dominant transport mechanism for reliable data transfer over the Internet. In this paper the researchers study the fundamental gains and limits of explicit loss labeling techniques employed to empower TCP in hybrid wired/wireless networks. The filter is re-instantiated to measure RTT and augment it with history information so as to distinguish between congestion and wireless losses, specifically to empower TCP NewReno in wired/wireless networks.

March 2009-
Companies that cannot adapt to address fluctuating business opportunities and challenges face serious downside risk. The ability to adopt new IT technology successfully can be a major enabler for change, while the inability can be a major anchor that holds a company back, preventing business evolution.
Superficially, it can seem relatively easy to make technology changes, but testing and ....
Troubleshooting Slow Networks with Wireshark
[ Source: Global Knowledge ]
June 2009-
Wireshark, the world's most popular open-source network analyzer, has become an essential tool to locate and diagnose the cause of network problems in the most efficient and cost-effective method possible. In March 2009, the Wireshark Certification Program was released to validate a candidate's knowledge of Wireshark functionality, TCP/IP troubleshooting, and network forensics/security. In this white paper, we examine how to use Wireshark to troubleshoot some of the top causes of poor network performance.

October 2009-
The last twenty years have seen the complexity of enterprise and telecoms service delivery infrastructures grow beyond the economic viability of systems put in place to enable service management personnel to keep order. Infrastructure change and complexity are too great to manually maintain business logic.
RiverMuse ushers in a new era of groundbreaking innovation in event management in order to cost effectively support the rapid adoption of a dynamic service delivery infrastructure by most ....
Using Steady-State TCP Behavior for Proactive Queue Management
[ Source: Los Alamos National Laboratory ]
January 2008-
This white paper assesses the use of steady-state TCP behavior knowledge for Proactive Queue Management (PQM). It shows how routers use flow parameters and the knowledge of TCP end-host behavior to intelligently mark packets to prevent queue build-up and thus prevent congestion from ever occurring, while at the same time presents high link utilization and low packet loss. Utilizing a queue management algorithm that tracks TCP behavior allows queue sizes to be deterministically stabilized at ....
The Importance of Network Time Synchronization
[ Source: Symmetricom ]
May 2009-
As you read this, your network of workstations and servers, each with their own clock, are time stamping files, email, transactions, etc., all the while your server logs are recording every manner of transaction in the event you need that information. At some point during the day it is quite likely that automatic processes such as archiving, directory synchronization, cron jobs, etc. will execute and alter files based on time stamps. Fundamental to all of ....
