Performance Evaluation of Voice Over Internet Protocol Reviews
Performance Evaluation of Voice Over Internet Protocol
This is a NAVAL POSTGRADUATE SCHOOL MONTEREY CA DEPT OF COMPUTER SCIENCE report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A875114. The abstract provided by the Pentagon follows: Voice over Internet Protocol (VoIP) was developed to emulate toll services with lower communication cost. In VoIP applications, voices are digitized and packetized into small blocks. These voice blocks are encapsulated in a sequence of voice packets using the Real-time Transport Protocol (RTP) and delivered by the User Datagram Protocol (UDP). To help VoIP applications deal with unpredictable network performance, the Real-time Transport Control Protocol (RTCP) is developed to monitor the performance of RTP packets and provide feedback to the VoIP applications. The feedback on packet delay, jitter, and loss rate enables the applications to adapt to network conditions to maintain a certain level of voice quality. With this architecture, the quality of service of VoIP relies on the effectiveness of the RTCP network performance report mechanism. This research collects RTCP performance reports from live traffic over real networks and compares their values with the statistics derived from direct measurements of RTP packets to evaluate the effectiveness of RTCP. The live experiments were conducted on networks resembling respectively, Local Area Network (LAN), Wide Area Network (WAN), campus network, and encrypted wireless LAN. Results from these experiments show that RTCP is effective for low delay networks but RTCP performance reports can be inaccurate for networks with large, volatile delays.

VoIP and Satellite Internet
VoIP has revolutionized the way telecommunication is done. Voice over Internet protocol allows voice packets to be sent over Internet bandwidth enabling cheap communication. There are many companies which offer voice over Internet services and some of the leading ones are Vonage, Skype, Yahoo and Net2Phone. Consumers can access VoIP over Internet connections like broadband and DSL. Satellite Internet is a new technology that has become very popular in recent times and VoIP providers are able to offer services to customers in remote regions using it. It will still take some time until VOIP by satellite is ultimately stabilized and customers can enjoy the full benefits.
Some of the challenges faced by service providers include packet loss, jitters and limited bandwidth. Service providers like Hughes and Skyframes which have their own satellites are teaming up with the VoIP providers to offer voice services to customers. Designing a VoIP network would require details on the bandwidth requirement for VoIP data. Satellite Internet providers are facing challenges on the bandwidth capacity that would be required to offer VoIP services via satellite channels. G.729 (b) encoding with a 40 b payload and header compression would require 10 Kbps of bandwidth. Packet loss is another challenge faced by service providers offering satellite VoIP services. Packet loss causes degradation in voice quality. The protocol used for voice traffic transmission is UDP/IP and if the data packets are corrupted they cannot be retransmitted. TCP/IP protocol allows retransmission of data packets. It is important to maintain very low bit error rates to offer high quality voice services to customers. Jitters are another technology hurdle that is faced by satellite VoIP service providers. It is used to calculate the delays in packet arrivals that happen because of network delay. If this factor is not within acceptable limits the quality of voice becomes poor and the receiver may not be able to enjoy a good conversation. Jitter buffers are used to overcome this hurdle and ensure that there is less delay in the network. Researchers and scientists are working relentlessly to overcome all hurdles that come in way of experiencing a smooth voice call through satellite Internet.
VoIP by satellite is not ideal because of some more factors. Latency factor refers to the time delay in locating the Geo-stationary satellite and the speed of light. There is a delay of 280 msec because of latency factor. Traffic congestion in the network also affects the quality of VoIP service. This can result in voice packets being dropped, delayed or reaching the receiver out of sequence. Compression technology is another parameter for delivering high quality VoIP service. There are two compression technologies that are followed as industry standards. The G.729 codec uses bandwidth of 18Kbps and RTP uses around 10 Kbps per second. If service providers are able to cope with the technological challenges of VoIP over satellite, it will not be long before remote areas of the United States can connect with the rest of the world.

So for your business, if you have DSL or broad IP provider, and you have phone line thru them, it will use the your IP provider’s data lines for phones, not traditional phone lines.
Advantage – Huge bandwidth.
Definition:
Voice over Internet Protocol (VoIP) is a general term for a family of transmission technologies for delivery of voice communications over IP networks such as the Internet or other packet-switched networks. Other terms frequently encountered and synonymous with VoIP are IP telephony, Internet telephony, voice over broadband (VoBB), broadband telephony, and broadband phone.
Internet telephony refers to communications services—voice, facsimile, and/or voice-messaging applications—that are transported via the Internet, rather than the public switched telephone network (PSTN). The basic steps involved in originating an Internet telephone call are conversion of the analog voice signal to digital format and compression/translation of the signal into Internet protocol (IP) packets for transmission over the Internet; the process is reversed at the receiving end.[1]
VoIP systems employ session control protocols to control the set-up and tear-down of calls as well as audio codecs which encode speech allowing transmission over an IP network as digital audio via an audio stream. Codec use is varied between different implementations of VoIP (and often a range of codecs are used); some implementations rely on narrowband and compressed speech, while others support high fidelity stereo codecs.

Voice over Internet Protocol ? Altering the way the World Communicates
It may seem like jumping into the dark but switching to a Voice over Internet Protocol telephone system, VOIP, is very simple. VOIP offers changes that can be detailed and many. These changes can be very beneficial to users who choose VOIP vendors such as Yahoo Messenger or Vonage. The world is using the phone differently thanks to VOIP.
Users should know what kind of service they wish to use before buying a new VOIP phone system. To choose the VOIP vendor that is right for you, you must compare every aspect of the services offered. If most calls being made are long distance, plans like Vonage or Skype might be helpful since they offer great long distance features. It is typical for VOIP services not to charge for long distance. This is especially the case between users on the same service. Long distance users can really benefit from establishing a network of this sort.
Lots of Voice over Internet Protocol services have a flat-rate monthly fee service. This plan lets users make unlimited calls. It is a good idea to compare services to get the greatest amount of features for your monthly fee. If a service only offers the bare minimum in features, you may want to pay a little more and get more services. For about a month, you can get a very simple package that will give you unlimited calling. This kind of deal may cause you to lose out on a lot of the great benefits inherent in VOIP.
Traditional phone services simply do not offer all the features you will find with broadband calling. VOIP offers features like emergency directory assistance numbers, call blocking, voicemail, caller ID, last number redial, call forwarding, local number portability, call waiting, and fax redirect. Really, you can get all of the features that are typical with a traditional phone company. Of course, these services are all offered with VOIP, but a lot of companies offer additional features like selecting your area code anywhere in the world, multi-ring features for calls that come while you are on another a call, global travel without long distance rates, instant connectivity to hot spots allowing you to connect with other VOIP users internationally in any internet capable area, and great back and forth connectivity with a personal computer to phone option. Additionally, full sets of contact lists can be stored on a removable hard drive.
Users who make lots of international calls may find that VOIP is just the missing piece they have been looking for. VOIP really gives lots of features to their users. This helps them to be worldwide leaders in communications at the very start of this venture. People who use VOIP services are happy with them. They say that these great services really support them in communicating around the world. Users report few, if any, problems. You don’t need to worry about VOIP disappearing.
Private electronics consultant, Cameron Tacassi knows the importance of using the proper chip inductor to help speed performance of VOIP systems as well as a custom transformer to achieve the best possible result. Cameron relies on Allied Components for his communication hardware needs.
