Bit Error Performance Events & Related Alarms Through the BBE event, whether the receiving side of local end detects bit error and whether the problem lies in the channel between the sending of remote end and receiving of local end can be identified. Through the FEBBE event, whether the receiving side of remote end detects bit error or whether the problem lies in the channel between the sending of local end and the receiving of remote end can be identified. Corresponding to three bit error remote performance events MSFEBBE, HPFEBBE and LPFEBBE, there are three bit error remote alarm events, Read More …

Principles of Bit Errors – I
Errors occurring to data during the transmission process are called Bit Errors (BER). It is a key parameter that is used in assessing systems that transmit digital data from one location to another. Specifically, it is the error of a single number between receiving and sending data signals. BER is critical for radio data links, Optical data systems (fiber), Ethernet. The basis of BER are same in all of these systems even though there are some differences in functioning of these systems, how they work and the way in which Bit Error rate is affected. . A good knowledge of the BER also enables Read More …
BGP Local Preference (LOCAL_PREF)
BGP LOCAL_PREF is the Second BGP attribute if we dive deep into BGP’s algorithm of best path selection followed by aggregate (detailed in my first post in BGP section). When an AS (autonomous system) has multiple routes to another AS, the LOCAL_PREF indicates the degree of preference for one route over the other routes. The route with the highest LOCAL_PREF value is preferred. You can watch the detailed video on LOCAL_PREF on our : LOCAL_PREF, Weight & MED are often confused with each other. LOCAL_PREF is different from Weight & MED. Unlike weight, LOCAL_PREF is not vendor specific (Weight is Cisco Read More …
Wireshark Operators
Wireshark is the most useful & popular tool for packet Level deep Network Analysis & Troubleshooting. Most importantly, it is open source. It is like a measuring meter or device to find and examine what is going on inside a network cable or port just like a multimeter is used by an electrician to examine what is going on inside an electric cable … but of course at much deeper level. Wireshark or such SW tools are not something very new. Such tools were available in the past as well but they were very expensive and proprietary because they were mostly Read More …
