The CommWorks architecture enables service providers to deploy large networks, combining various types of media, in a unified networking environment. The CommWorks architecture also allows – through a single converged network – to provide broadband IP telephony services, with wireless data transmission and remote control access. This standards-based CommWorks solution designed with open interfaces throughout the network, meets the needs of the telecommunications industry thanks to the availability of a coherent architecture that allows, through a single unified network environment, the provision of multiple services.
The CommWorks architecture simplifies the migration from today's analog networks to the next generation, that is, the generation of converged networks enabled with option packages that allow providers to offer better differentiated services, create new business opportunities that generate profits and gain a unique position in the market.
The CommWorks architecture differs from similar ones by:
• Openness, resulting in the rapid creation of services that generate new revenue
• Versatility, for maximum integration and multi-service capability.
• Ability to evolve, according to the service needs of suppliers
This architecture is characterized by a three-level structure. The first two layers meet universal connectivity requirements that include protocol mediation signaling, while the third level creates an environment for service and application development.
The Interconnectivity Processing level (Layer 1) provides universal connectivity across a variety of access network options. This line employs media gateway access functions to integrate the multiple types of traffic and to accommodate different network accesses. The media processing layer encompasses the reliable Total Control 1000 multi-service access platform and the new Total Control 2000 multi-service access platform.
The Network Service Management and Control level (Layer 2) provides universal signaling and control through the regulation protocol. This line connects different signals and control protocols allowing traffic to travel evenly across different networks. This tier also provides powerful network and element management, as well as network distribution service. It allows Layer 3 connection services to be equally accessible to all network users by providing maximum consistency in service, regardless of access to the medium used for network connection. The control and signaling level includes the CommWorks 4000.
The Service Creation tier (Layer 3) provides a service creation environment that leverages 3Com's open interfaces and strategic partners for rapid application and service organization. This level is divided into three groups: services based on network needs, such as provisions and directory of guides; services based on user needs, such as profiling, fees and content promotion; and application-needs-based services, such as message unification and improved faxing.
With proven market leadership in improving information systems, IP telephony and wireless access to information, CommWorks is leading the evolution of IP products that will provide the tools for the next generation of service providers.
Webcasting Rock in Rio
TV&Video: What aspects should be considered for The production of TV on the Internet?
Werner Lessberg Koenig: The different equipment that should be considered for the production of TV on the Internet would be the CommWorks equipment of total remote access.
TV&V: What are the fundamental differences between producing for broadcasting and webcasting?
W.L.K.: The fundamental differences are:
• Broadcasting: is the direct transmission of video via satellite, air or cable
• Webcasting: is the transmission of video over an IP network.
• Multicasting: It is a protocol that serves to improve the efficiency of a network, avoiding the duplication of traffic. In the case of a webcasting that uses multicasting , the voice and video transmission arrives from the provider's server, such as AOL, to a common point, and from there to the CommWorks Total Control 1000 router, which transmits the signal to all users saving network resources and allowing efficient distribution for all users.
TV&V: Are the same technical devices used?
W.L.K.: No, webcasting uses an IP network to transmit the voice and video signal, what changes is the transport and distribution of the signal.
TV&V: What is CommWorks technology support? Could you describe the fundamental aspects of this service?
W.L.K.: CommWorks Corporation's technological support, during Rock in Rio, consisted of providing the IP infrastructure through the Total Control 1000 remote access platform for America Online users in Brazil, Argentina and Mexico.
TV&V: What will be the options for interactivity?
W.L.K.: CommWorks ' Total Control platform supports the use of applications (such as streaming video) that allow interactivity in multicasting. For example, during a multicasting you can have a question and answer window in conference calls.
TV&V: To achieve these interactivity functions, what kind of technological resources are required?
W.L.K.: A suitable software .
TV&V: Once on the air, what are the audio and video signals like on the Internet? Do they have enough quality to enjoy a show of these characteristics?
W.L.K.: The signal depends on the telecommunications infrastructure, that is, the quality of telephone lines (in case of using dial up access) and also on the user's equipment.
TV&V: How will the stream be accessible?
W.L.K.: In the specific case of Rock in Rio, AOL users had direct access to the webcast once they had the correct address of the Rock in Rio website.
TV&V: What resources should the user have?
W.L.K.: A computer with Internet access with video and audio capability.
TV&V: What are the main applications that this type of TV production will have in the near future?
W.L.K.: Webcasting, video on demand and the convergence of technologies will become increasingly important in daily life. Business applications such as distance education, conference calls and world-class events such as Rock in Rio will become increasingly frequent. In addition, mobile devices based on IP technologies (phones, palms, etc.) will give way to a new lifestyle. The immediate demand for clear and secure information will be increasingly imminent, giving way to the use of emerging technologies, such as access to 3G networks that are currently being implemented in various parts of the world, using our CommWorks architecture.
