Despite these network technologies remaining in use today, this kind of network lost attention after the advent of Ethernet networks. Today Ethernet is, by far, the most popular layer 2 technology. Conventional Internet routers and network switches operate on a best-effort basis. This equipment is less expensive, less complex and faster and ...
All of the factors above, coupled with user requirements and user perceptions, play a role in determining the perceived 'fastness' or utility, of a network connection. The relationship between throughput, latency, and user experience is most aptly understood in the context of a shared network medium, and as a scheduling problem.
A backbone can tie together diverse networks within the same building, across different buildings, or over a wide area. When designing a network backbone, network performance and network congestion are critical factors to take into account. Normally, the backbone network's capacity is greater than that of the individual networks connected to it.
WAN optimization is a collection of techniques for improving data transfer across wide area networks (WANs). In 2008, the WAN optimization market was estimated to be $1 billion, [1] and was to grow to $4.4 billion by 2014 according to Gartner, [2] a technology research firm. In 2015 Gartner estimated the WAN optimization market to be a $1.1 ...
FM algorithm is a linear time heuristic for improving network partitions. New features to K-L heuristic: Aims at reducing net-cut costs; the concept of cutsize is extended to hypergraphs. Only a single vertex is moved across the cut in a single move. Vertices are weighted. Can handle "unbalanced" partitions; a balance factor is introduced.
IEEE 802.1ag is an amendment to the IEEE 802.1Q networking standard which introduces Connectivity Fault Management (CFM). This defines protocols and practices for the operations, administration, and maintenance (OAM) of paths through 802.1 bridges and local area networks (LANs). The final version was approved by the IEEE in 2007. [1]
Performance-enhancing proxies (PEPs) are network agents designed to improve the end-to-end performance of some communication protocols. PEP standards are defined in RFC 3135 (PEPs intended to mitigate link-related degradations) and RFC 3449 (TCP performance implications of network path asymmetry).
NetQoS, [1] which sells network performance management software and services, was co-founded by Joel Trammell in 1999 [2] and acquired by CA Technologies in 2009. [3] [4] [5] The company's name refers to Network Quality of Service. [6] Their ReportAnalyzer provides "real-time visibility into network traffic" [7] and seeks to improve network ...
