Principles of Bit Errors – II

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 […]

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 […]

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 […]

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 […]
