Bandwith, Latency dan Jitter

The Bandwith

If you think of the Internet as a series of tubes, Bandwidth is how wide the tube is. Indeed, it’s named bandwidth because it describes the width of the communications band. The wider the tube the more data you can send in parallel.

The Latency

Latency is the length of the tube between two points. The key point here that gets missed is that, regardless of how much data you are sending (how much bandwith), you still have to move it the distance from point A to point B. That takes time and that is the latency.

The Jitter

Simply said, time difference in packet inter-arrival time to their destination can be called jitter. In this image above, you can notice that the time it takes for packets to be send is not the same as the period in which the will arrive at the receiver side. One of the packets encounters some delay on his way and it is received little later than it was assumed. Here are the jitter buffers entering the story. They will mitigate packet delay if required. VoIP packets in networks have very changeable packet inter-arrival intervals because they are usually smaller than normal data packets and are therefore more numerous with bigger chance to get some delay.


Be patient as a main service!

Patience in service is key to the success of the service itself.
– based on story of Mr. Budiono (Delphi Suhu)

Kesabaran dalam pelayanan (service) adalah kunci dari kesuksesan sebuah pelayanan

Sebuah pelayanan seringkali berhadapan dengan pengguna jasa yang pemarah, yang tidak toleran atas kesalahan sedikit saja baik itu kesalahan dari sisi orang yang melayani, dari sisi pengguna jasa, apalagi faktor eksternal.

Jika kita sebagai penyedia layanan, lalu dimarahi. Kemudia hal ini diiringi dengan kesabaran dan keyakinan bahwa emosi akan tunduk terhadap kesabaran, maka suatu saat orang itu akan menjadi santun kepada kita.

Beda cerita jika pengguna marah, lalu kita juga marah, maka akan berujung derita.

Kita harus perhatikan resiko yang lebih besar dari pembalasan. Yang jelas, tidak ada untung bagi seorang pemarah atau dari sebuah balas dendam.

So, be patient!

How to alocate vSphere server effectively?

Read the article from this link :

Understanding CPU & Memory Management in vSphere

The advices from that article in a brief are:

  1. Allocate with estimation resource,
  2. Try it, monitor it, then analyze it
  3. Re-allocate again

“So, effectively managing your CPU and memory resources is really a two-step process. First, don’t go overboard with resources when creating new VMs. Try and be a bit conservative to start out.  Then, monitor your environment continually with a product like SolarWinds Virtualization Manager so you can see the actual VM resource needs. The beauty of virtualization is that it makes it really easy to add or remove resources from a virtual machine. If you want to experience the maximum benefit that virtualization provides and get the most cost savings from it, right-sizing is the key to achieving that.”
