Redundant Network Traffic Elimination Techniques: A comprehensive Survey
نویسندگان
چکیده
a large amount of popular content is transformed across the network for different purposes. This transformed content comprises large amount of duplication that consume bandwidth inefficiently and degrade network performance. Redundant Traffic Elimination (RTE) also known as data deduplication detects and removes repeated chunks of data across network flows, protocols, and applications, with the purpose of reducing bandwidth usage. In this paper we survey state of the art RTE techniques (WAN optimization, protocol independent, PACK, SMART-RE, EndTo-End elimination etc.) implemented in various types of networks. We categorize the techniques based on the problem solution perspective, critically analyze the techniques, and find gaps that need consideration in future. Results show that already implemented RTE techniques considerably remove the repeated content and improve network performance. However, still there are gaps especially in mobile networks, wireless and cloud computing area that needs consideration in future.

Enhancing redundant network traffic elimination
Protocol-independent redundant traffic elimination (RTE) is a method to detect and remove redundant chunks of data from network-layer packets by using caching at both ends of a network link or path. In this paper, we propose a set of techniques to improve the effectiveness of packet-level RTE. In particular, we consider two bypass techniques, with one based on packet size, and the other based o...
متن کاملIn-Network Caching vs. Redundancy Elimination
Network-level Redundancy Elimination (RE) techniques have been proposed to reduce the amount of traffic in the Internet. and the costs of the WAN access in the Internet. RE middleboxes are usually placed in the network access gateways and strip off the repeated data from the packets. More recently, generic network-level caching architectures have been proposed as alternative to reduce the redun...
متن کاملLow-Overhead Dynamic Sampling for Redundant Traffic Elimination
Protocol-independent redundant traffic elimination (RTE) is an "on the fly" method for detecting and removing redundant chunks of data from network-layer packets traversing a constrained link or path. Efficient algorithms are needed to sample data chunks and detect redundancy, so that RTE does not hinder network throughput. A recently proposed static algorithm samples chunks based on highly-red...
متن کاملBehavioral Analysis of Traffic Flow for an Effective Network Traffic Identification
Fast and accurate network traffic identification is becoming essential for network management, high quality of service control and early detection of network traffic abnormalities. Techniques based on statistical features of packet flows have recently become popular for network classification due to the limitations of traditional port and payload based methods. In this paper, we propose a metho...
متن کاملSMART Overlay: Duplicate Traffic Elimination
Internet consumes 5% of world-wide energy. The fact is that 90% of Internet traffic is video and mostly “redundant.” As an example, 10% of the most popular videos account for 90% of total views at YouTube. As a result, redundant data are repeatedly transmitted over the Internet. Our challenge is to design the first traffic deduplication technique for more efficient network communications betwee...
