There are a variety of online business concepts that rely heavily on advanced web traffic engineering applications. When an online merchant or site owner is in the process of planning and constructing a website, he must consider the options available to him when it comes to bandwidth and storage space. Both of these are vital elements when it comes to running an online store or forum. Without a large enough amount of bandwidth and storage space, an online website will not be functional. In the case of a forum, the number of active visitors can determine how much profit a site has and how successful it can be. For this reason, traffic engineering solutions are essential in both cases.
Traffic engineering can also be applied to link weights and hyperlinks. Link weights affect the number of links a website can have relative to other websites. Higher link weights translate into higher page rankings for the site, but they also make the site more difficult to maneuver in search engines. A way to counter this problem is by using algorithms and other traffic engineering techniques to boost up link weights.
Another important example of an application of traffic engineering comes from routing. Routing is the process of determining the shortest path between two points on the Internet. In the case of a network, this usually means using a routing algorithm. The length of the shortest route between two points is referred to as the hop count. An effective traffic engineering strategy uses a combination of hop tables, directory structure and other algorithms to determine the best path.
Physical bandwidth value refers to the total amount of time it will take for data packets to traverse between two nodes on a local network. Network operators often assign bandwidth value based on the geographical location of the network’s end-users. For instance, if an office in San Francisco is going to send requests to a web site that is located in New York, the desired amount of bandwidth will depend on the physical distance between the two locations. Assigning bandwidth based on geographical proximity usually equals the closest neighbor.
Some traffic engineering applications may also use r SVP or statistical velocity model. This traffic engineering technique calculates the maximum speed that a machine can attain given its current condition. If a machine has a higher maximum speed than its neighbors, it is said to be “switching ready”. In some networks, especially those that are highly public and have a high volume of visitors, switching ready machines are allocated with relatively high bandwidth values.
An important application of traffic engineering is through the use of tunnels. Tunneling is sometimes used when there is a high volume of offline traffic, especially in conjunction with remote access tools like the sniffer and device driver. The purpose of tunnels is to create temporary networks where connections can be established without requiring the use of network nodes. This type of traffic engineering is called packet forwarding, and it is usually applied during troubleshooting operations. In this case, normal networks are redirected to the temporary servers for connection testing purposes.
Aside from these types of techniques, traffic engineering can also employ certain technologies. One such technology is the content delivery network (CDN), which involves the use of large numbers of local area network (LAN) computers for rapid application delivery. Such applications include real-time video streaming, where video content can be delivered from one location to another without the need for additional hardware. Other examples include content distribution services and application service providers (ASPs). Some businesses, such as gaming sites, also employ the delivery of game data from servers to customers on a CDN basis. MPLS and VDSL technologies are also being tested as effective traffic engineering solutions.
Traffic engineering is not limited to the application of tunneling techniques. It also includes measures like link weights and congestion control. Link weight refers to the ratio of the total amount of traffic to the amount of network delay. In terms of congestion control, this refers to the number of queries as well as the average latency of each request.
