Packet switching is a network transmission method that sees data sent in small blocks called packets rather than as a continuous stream. Sending data in this way helps to improve the robustness and ...

A digital network technology that breaks up a message into smaller chunks (packets) for transmission. Unlike circuit switching in traditional telephone networks, which requires the establishment of a ...

As we mentioned last time, there was an entire industry built around using TDM bandwidth efficiently due to the compelling economics of building corporate private-line networks. By the late 1980s, ...

In packet switching architectures, multicast transmission to two or more ports is inherent to the forwarding mechanics of certain protocols while strictly operational necessities in others. For ...

As Internet usage continues its growth, carriers continue to see a steady increase in packet data traffic on their metro networks. Cable providers, or multiservice operators, are experiencing similar ...

Circuits as WAN connections battled successfully against packets for years because they guaranteed bandwidth, no matter what. If you bought a T-1 circuit, the service provider nailed up 1.5Mbps from ...

You may recall that Ethernet networks are based on a protocol calledCarrier Sense Multiple Access with Collision Detection, commonly knownas CSMA/CD. This means that data packets from the various ...

The infrastructure of 2G and 3G cellular networks are similar. They comprise an air interface between the user's mobile device and the base station and two core networks; one for circuit-switched ...

Sprint Corp. is to change its entire circuit-switched telephone network to packet technology in an attempt to keep up with customer demand for capacity, the company announced today. All 8 million of ...

Verizon Communications this week announced plans to shift its nationwide telecommunications network to packet-switched technology as part of a plan to offer new voice-over-IP and multimedia services.

Four factors are key in designing new networking boxes: power consumption, density, cost, and scalability. Reducing power consumption means using a minimum number of efficient integrated links and ...

Despite the industry attention it has received, voice-over-IP (VoIP) is not the only way to send voice across a packet-switched network. In fact, it may not even be the best approach for some ...
