Your organization also needs to commit resources to managing the use of video conferencing over your internal IP network, and to interfacing with your end users. Satcom deployed at lower levels. In a traditional routed IP network, each router makes an independent forwarding decision for each packet based solely on the packet's network-layer header. In emerging markets, the challenge is to provide broadband, and that means deploying 3G, but also ensuring national and international backbones capacity, introducing packet and IP in all parts of the network. Enterprises that want to get the most use of Voice over IP (VOIP) need to understand the issues involved in hardening their network and Internet infrastructure before they begin to deploy this technology. For more information, visit www.sonus.net. The government should continue to encourage investment in this transition. Sonus products are supported by a global services team with experience in design, deployment and maintenance of some of the world's largest and most complex IP networks. Average loop lengths and population densities affect the costs of deploying networks, both mobile or fixed. Thus, every time a packet arrives at a router, the router has to “think through” where to send Another emerging spec is the ITU's transport-MPLS (T-MPLS), which is designed to simplify deployment of Ethernet services. A broad trend indicates that satcom is being used at “The transition to IP networks is ongoing though there are still some point-to-point communications. Its recent restructuring of the Universal Service Fund, for example, made deployment to unserved areas economically feasible by transferring existing federal subsidies from voice-only copper networks to the build-out of broadband IP-based networks. Shifting our nation's communications networks to all-IP is critical to ensuring consumer access to the most modern communications services.
