Importance of NTP server in Network

Network Time Synchronization is turning into a lot of necessary than ever in today’s networks as firms have come back to accept their networks for all their communication wants. Since the 1990′s we’ve seen AN explosion of TCP/IP network usage and de-centralized network resources. Mainframes became PC’s and having totally different networks for each application (TDM Voice, SNA Mainframe, video surveillance building access, audio rendering, video rendering, IP information Networks) is quickly being replaced with IP Networks running all of those applications as totally different services over identical network. The goal of getting one network running several services, rather than a unique disparate network per service, could be a valid and less expensive approach to Enterprise communication wants.
IP Networks are currently the first communication medium for many Enterprise application wants as well as voice, wireless, information and video communications with the goal of having the ability to cut back the value and range of various networks and systems, whereas at identical time, permitting applications and services augmented access to information which will be quickly shared between one another.
Companies nowadays progressively request network performance information and aren’t any longer happy by basic IP property alone. The questions about their information, applications, and services include not simply `if’, and `how much’ of the info arrived, however precisely `when’ did it arrive? IP Networks currently need Quality of Service (QoS), WAN optimisation, secured delivery and reciepts, traffic priorities, and a lot of on the far side basic IP property services. All of those demands square {measure} setting out to drive a bigger want for patrons to be able to accurately measure network, service, and application performance, quality, and availableness.
This augmented concentrate on network performance has placed new demands on the distribution of your time inside the network for several reasons. Log file correlation, property take a look at and activity, event sequencing and forensics rely on time (Time of Day) system clock synchronization as a elementary demand.
Performance metrics like unidirectional (OW) and trip (RTT) network latencies, VoIP Mean Opinion Scores (MoS), packet loss, packet rearrangement, and packet interarrival delay (jitter), information compression, and queue delay are watched on a daily basis with nice interest by network operations teams. Most of those metrics and information have a time stamp, or time of day data related to them, particularly single-path unidirectional delay. it’s quite common in networks to own a unique traffic path on each components of a round-trip, that makes exploitation round-trip metrics alone not as helpful as unidirectional metrics in these eventualities.
