Quality of Service Networking

Overview Quality of Service (QoS) refers to the capability of a network to provide better service to selected network traffic over various technologies, including Frame Relay, Asynchronous Transfer Mode (ATM), Ethernet and 802.1 networks, SONET, and IP-routed networks that may use any or all of these underlying technologies. The primary goal of QoS is to provide priority including dedicated bandwidth, controlled jitter and latency (required by some real-time and interactive traffic), and improved loss characteristics. Also important is making sure that providing priority for one or more flows does not make other flows fail. QoS technologies provide the elemental building blocks that will be used for future business applications in campus, WAN and service provider networks.

Frame relay and ATM are complementary technologies says panel

Frame relay and asynchronous transfer mode (ATM) are complementary rather than competitive technologies, according to a panel of experts at the Frame Relay Forum at Supercomm '99 in Atlanta. The research predicts the frame relay services market...

Has Gigabit Ethernet come of age?

The advent of its fatter version is opening up the transfer of WAN data from ATM, frame-relay or packet over SONET/SDH to a potentially more efficient and cheaper method. However, as yet Gigabit Ethernet and its even fatter younger sibling 10...

MPLS: The icing on the networking cake?

Are we on the verge of a step-change in the quality of networking, a change that will put what we've come to expect from the likes of Asynchronous Transfer Mode (ATM), Frame Relay and all-IP to shame?

Convergence: lower costs and extra flexibility - the IP VPN promise

For multinationals, moving from international Frame Relay circuits to an MPLS IP VPN does not necessarily save money in the short term though longer-term financial payoffs are already being reported by early adopters.

Frame Relay suffers as IP VPNs and more move on up

Out go ATM, Frame Relay and leased lines. At the top of the technologies labelled as 'in decline' is Frame Relay, which will generate 26 per cent less revenue than in the earlier 12-month period. In come DSL, Ethernet and IP virtual private...

Gartner: Don't believe the tech security myths

Internet reliability might not be perfect but it is good enough for most purposes, Gartner said, citing research showing 89 per cent of organisations that have switched from frame relay or ATM (asynchronous transfer mode) to IP links were...

Virtualisation: Architectual Considerations and other Evaluation Criteria

In the past several years, server virtualisation technology has moved quickly and firmly into the IT mainstream. Of the many approaches to system virtualisation available in the market today, VMware's hypervisor architecture has gained the greatest market acceptance. This paper examines the architectural issues, solution support, and enterprise readiness required when deploying such a virtualisation solution.
