Synchronize a Cisco router's clock with Network Time Protocol (NTP)

Time Protocol (NTP), a protocol designed to synchronize the clocks of computers over a network, for policyears. NTP Version 3 is a standard protocol ormalized in RFC 1305 protocol hat uses the user datateprotocol (UDP) and Port 123. Unlike PCs or servers, Cisco network devices specifically need to run NTP to synchronize the time and date. That's because most Cisco devices don't have an internal clock. For example, when a Cisco 2600 or 3600 series router loses power or the network administrator

How to build a better search engine by measuring query quality

The search engine is built on the use of the standard set of real-world test cases, which allows developers to measure the relative effectiveness of alternative methods. This article discusses the NIST Text Retrieval Conference (TREC) project, which creates an infrastructure for measuring the quality of query results. We always think that text file queries in our native language are guaranteed, but web search engines like Yahoo, Google and Bing don't
