Not that it should come as a surprise, since I have written about it in the past, but looks like there is more proof that Telemex is giving the VoIP providers a “club bouncer” treatment. A major daily has picked up on the problems VoIP users are having over Telemex. Even US trade office has become involved. via

  2. FACT 1
    • Infinitum service is designed to provide Internet access at the best possible quality of service module or “Best-Effort (BE)â€? as it is known worldwide, in which there is no mechanical implementation that differentiate services or applications.
    • This is the way the Internet was originally conceived, based on the delivery of “best-effortâ€? data, point-by-point.
    • Infinitum is not designed to distinguish traffic types or priorities. All of the data packages are treated equally.
    • Infinitum service will be provided without a commitment value in certain parameters like in the case of percentage losses in the database, jitter, delays, etc.
    • We cannot guarantee continuous functioning under this definition of net in real time applications, like remote video, multimedia conferences, Internet voice or virtual reality, because of variable delays and the potential loss that naturally occurs in the Internet.

    FACT 2
    • All ports are open in the Infinitum service.
    • Firewalls on the customer’s side can cause that certain applications cannot use some of the ports.
    • Telmex does not block any sites.
    • Like all of the major ISP’s of the world, a DNS degradation caused by worms, request an explosion of information and will temporarily compromise the service.

    FACT 3
    • PTP (Peer-to-Peer )traffic deteriorates the user experience and can cause congestion to Internet access.
    • The congestion caused by P2P is because of the use of applications like: Kazza, Edonkey, Bittorrent, Limewire, Morpheus, Emule, etc,
    • P2P will radically change traffic behavior.
    • P2P increases operator costs on traffic and Internet capacity.
    • P2P complicates Internet planning.
    • P2P prevents the development of sensitive services to quality services
    • (QoS)(VoIP)
    • Infinitum service has experienced enourmus P2P traffic explosion. That is very similar to the one experienced by European operators: P2P traffic can variate between60%-80% of the total.
    • In the U.S., traffic fluctuation is between 60% to 65%
    • 10% of customers consume 80% of the available bandwidth .
    It is not only what customers´ download from the Internet (perceptible to them), it is also what other consumers are downloading in other PC´s (not perceptible), what consumes all of the customer´savailable bandwidth. .
    • The impact on Internet traffic on P2P applications is not only measured by the amount and file size exchanged, but also by the process involved in this system.
    • All equipment connected to these applications establish constant communication and are victims of the process of other equipments searching also for files and because of this, the equipment is permanently emitting information.
    • It is even worse when a customer decides to configure a PC as Supernode that absorbs all of the available bandwidth.

    FACT 4

    • The unpredictable and continuous “wormâ€? attack, and SPAM has grown out of proportion
    • Worms like “MyDoom and Bagleâ€? (the Troyan like Phatbol) give control of the equipment to “Hackersâ€?. This huge net of zombies and compromised equipment (so-called “Botnetsâ€?) can be used for “SPAMâ€? distribution or used as a platform for DDos attacks (denial of service) throughout the Internet.
    • SPAMERS use these mechanisms to hide their real IP addresses.
    • A huge amount of SPAM (between 60% to 80%) is originated in “SPAM ZOMBIESâ€?.
    • When you have a large group of equipment carrying out these attacks, it is very difficult to locate the origin of these attacks and solve them in real time , without causing massive interference on other Internet operations and to real and legitimate users.

    FACT 5
    The challenge for the major ISP´s is:
    • Introduce control mechanisms without creating Internet delays.
    • Face constant traffic growth, risk of degradation of the service and the Internet costs related to P2P traffic.

    FACT 6
    • For Infinitum service we have not implemented a technology that will make the prioritization of some Internet services possible. Eventually, we will evolve in this direction in order to provide and guarantee the provision and charge of these services.
    • Eventually, we will offer Internet services with a different commitment “QoSâ€? (Quality of service), with a SLA mechanism (service level agreements).
    • In order to support services with “Real timeâ€? quality, we need to modify the infrastructure to follow up with these Internet characteristics from beginning to end.
    • We will acquire the capacity to control the distribution of Internet bandwidth for each user with different types of traffic. Therefore, we need to divide total traffic in different categories and assign a minimum percentage of total bandwidth to each one, under high usage and congestion conditions.
    • These different kinds of traffic can represent different kinds of users and protocols.
    • In a Net with these characteristics, the cost for the use of this particular service will be higher than the traditional best-effort transfer.

    FACT 7
    • Recent surveys reflect that Infinitum is a product with the highest satisfaction index that is above average of the G-8 Group members.
    • Our commitment is to offer our customers with the best bandwidth service and we constantly improve the infrastructure introduce new benefits and enhance capacity.

    ANNEX.

    Clauses from the contract between the user and Prodigy INFINITUM.
    SEVENTH. POLICIES OF INTERNET USE.

    The use of the SERVICE as a Customer, implies the acceptance and conformity of the following:

    • The customer is aware of the nature of the INTERNET and its limitations, its technical qualities and the response time to consult, question, or transfer data and information.
    • Social, political cultural, among other events, can sometimes cause that the use of the INTERNET to increase significantly affecting optimal operational conditions., causing a temporary saturation that creates a delay in the Service.
    • The customer understands that the Internet is a net in a net of networks, and the paralyzation of one of these nets can cause temporary saturation that slows down Service.
    • TELMEX will not be held responsible for any damage or loss of information by the customer, caused by configuration, delays, non-delivery, failed deliveries, errors or Service interruption.
    • The customer recognizes that any information, product or service available through the INTERNET, different from those provided by TELMEX, are provided by other users or other parties, which are responsible of supporting or maintaining their information, products or services.

    1. Telmex is Still a Monopoly in Mexico and there is not question about the fact service is not good.
      Rates of GOD very high. Which eans are not competitive. A very easay way to proof this is that Telmex Claim their rates has not changed the last years.
      How can be possible a company can survive and still has profit if the rates are the same than years ago.
      That proofs are a bunch of RATS!!!

      In the other hand the actitude of Telmex workers has not changed too much. They still believe are the Kings in this market and in the past is very often to see the actitude of this people. Like if the made a favor to Customer when is in the other way. Customer pay their salaries.

      In doesn’t how many arguments can be written TELMEX is Company which service ….Sting…

      If we still continue in Mexico with this kind of companies this Country will be always in the same situation or worst.
      Companies like Telmex, Comosion Federal de Electricidad, etc. are just a heavy weight for all Mexicans!!!

  3. Since all telecom operators face this kind of challenge, many of them are using the same trick against VoIP traffic growth. The ones who worry the most currently are mobile operators, with the coming of 3G/UMTS: this enables customers to convert their expensive and limited voice traffic into cheaper data traffic, and the cost of data traffic is expected to drop sharply in the future as competition increases. For example, SFR in France is doing pretty much the same as Telmex for its users : it detects VoIP users by detecting typical traffic patterns, then introduces random delays / bandwidth variation to degrade the service.

  4. Ror, how sure are you about SFR? actually can you send me more details on this?

    thanks

  7. 30,000 Pounds of Bananas

    This morning, after my morning class and before dropping my girlfriend off at her work, we went to pay the phone bill at Telmex (who according to Om Malik has tried blocking Skype). This is still a process that amazes me. It shouldn’t. I should be use…

  8. Do the cable internet providers generally allow VOIP connections?

  9. I didn’t had any problems in Telmex before until today. I’ve call once or twice a week to ukraine, every week, all this year.
    Today, the call was hanging after one or two minutes on a call.
    Then I decided to call Skype-to-phone, it was the exact same thing, (so, it was not a problem in the other end), the call hanged in 1-2 minutes.
    Definely something wrong is going on.

I s this a coincidence or the reason…..
    If not , will the Vonage quality return as mysteriously as it vanished or are we screwed?
