cisco h 323 gatekeeper

Your job is to make a wide use of the applications of video conferencing and multi-media . How would you deal with bandwidth answer (T1, DS3, OCx/Sonet, etc.) that would be better to your necessities and will merge that conclusion into your network cover these applications?

my opinion is that it counts on the type of service and QoS you are considering. For instance, by saying “video” you imply video conferencing and not something similar to VoD. The variety of Bandwidth demands depends on your service necessities.

Good example is cisco  h 323 gatekeeper  IPTV services, its image efficiency counts on the encrypting deployed: MPEG-2 needs approx. 3.75 Mbps, while MPEG-4 requires approx. 2 Mbps to function with the same high-quality image results. Besides, IP Multicast is used to convey the broadcast TV to the viewers, which causes the recommended bandwidth to be subjected to the list of free channels and the encrypting rate. approx. 750 Mbps of bandwidth will be needed for 200 channels of MPEG-2 in standard definition .while cisco  h 323 gatekeeper VoD is a unicast per-viewer channel. The users of 1000 standard definition VoD will take appro. 3.75 Mbps.

The cisco  h 323 gatekeeper QoS demands for H.323 video conferencing usage (SIP could be different again) can be prepared on the “Rule of 75″ by estimating the lowest bandwidth needed by each of your applications ( e.g., video, voice, data). The overall bandwidth is a necessity for any of the applied hyperlink and it should take Less than 75% of the entire usable bandwidth on the hyperlink. The 75% condition earns access to bandwidth needed for over head traffic like routing, Layer 2 keepalives and additional applications, like the electronic mail, HTTP etc.

Preparation for cisco  h 323 gatekeeper , should take many trends like:

Matters like the list of concurrent users and some stuff on video conferencing looking into Cisco’s proposed answers should be put into consideration and TANDBERG boxes as well.

cisco  h 323 gatekeeper regards every 766Kb to be a “slow link” for VOIP. The criticality of the sites should be considered as well, so you may want to use two different connections. The superiority of your multi-media applications over the other applications make QoS only gives a priority to whoever goes first.

A fine service line of non-multi-media applications (VOIP) is required. For that bandwidth must have the ability to deal with the essential applications in the net.

Moreover, you’ll have to put in mind that the bandwidth aggregation at the Data Center requires to cope with or pass all inward distant site traffic. Meaning that if three remote sites are all with T1s, I’ll ask for much more than one T1 at the Data Center to handle the traffic. Put in mind that if not a Greenfield so baseline should be it.

Once it refers to streaming video, bi-directional – you have to study the quality of the compression you are prepared to apply. If you are prepared to practice high definition cisco  h 323 gatekeeper video 1 stream it is required to have 2MB or more in the streaming of the accessed video.

In order to direct video to your computer, you’ll have to be certain that you obtain 2MB download speed. Additional matter for you to remember is latency and loss of packets. My advice is to stay aside from wireless because this type of application will add latency and make problems afterward. DS3 bandwidth and anything higher would easily deal with your requirements but it may be over kill.

Without being aware of every thing, it is difficult to support cisco  h 323 gatekeeper an accurate solution, but, one may still determine an organised technique for estimating the needed bandwidth. When you acknowledge the bandwidth needs, it will be nearly about managing the appropriate economical means to arrange the bandwidth from a network supplier in the area.
