The people at Peerialism believe we can make better use of the internet by sharing resources more efficiently. If internet is to fulfill its promises as the media hub of the future, we need new solutions – peerialistic solutions – that benefit all the key parties; the consumer, the content owner and the operator. A peerialistic solution uses the next generation of p2p technologies to share resources – bandwidth, storage and processing power – to improve services and businesses. To achieve this, Peerialism has gathered some of the world’s most prominent researcher in the areas of distributed computing, p2p overlay networks and network optimization. The company is based in Stockholm and Cairo.

Mesmerizer: An effecitve tool for a complete peer-to-peer software development life-cycle

News
Abstract: In this paper we present what are, in our experience, the best practices in Peer-To-Peer(P2P) application development and how we combined them in a middleware platform called Mesmerizer. We explain how simulation is an integral part of the development process and not just an assessment tool. We then present our component-based event-driven framework for P2P application development, which can be used to execute multiple instances of the same application in a strictly controlled manner over an emulated network layer for simulation/testing, or a single application in a concurrent environment for deployment purpose. We highlight modeling aspects that are of critical importance for designing and testing P2P applications, e.g. the emulation of Network Address Translation and bandwidth dynamics. We show how our simulator scales when emulating low-level bandwidth characteristics of…

Network traffic optimization

News
PeerNet helps broadband operators to minimize network traffic by making better use of the existing infrastructure. Large and popular content files are temporarily stored and distributed from local P2P-caches in the access networks, reducing peak traffic loads on weak links further up in the network. Product features: Content type agnostic. Dynamic traffic detection; Caching content with largest network traffic impact. Fault tolerant: P2P caching nodes can fail without damaging QoS. Cost efficient: Caching on inexpensive consumer grade hardware. Diagram 2. Decrease in link load from using locality aware P2P. (Source: H. Xie, A. Krishnamurthy, 2007, "P4P: Explicit Communications for Cooperative Control Between P2P and Network Providers")

Video distribution

News, Okategoriserade
Peerialism’s product for video distribution over internet – PeerTV – enables content owners to distribute better quality video at significantly lower cost to many more viewers. Cost savings are between 50% to 90% depending on network conditions whilst the maximum number of simultaneous viewers is almost limitless. Product features: Support for RTP streaming. Support for HTTP progressive download. Support for video on demand. Player and codec agnostic: No new player needed. Modifiable QoS settings for customer specific requirements. Locality aware: ISP friendly. Diagram 1. U.S. Internet video traffic increase between 2000 and 2007. (Source: Cisco, 2007, "The Exabyte Era")   PeerTV has been acquired by MPS Broadband AB.

Peer-to-peer overlay networks

News
Peerialism AB develops peerialistic solutions to transport and store data on the Internet. Example solutions are video distribution for content owners and IP traffic optimization for broadband operators. The solutions are based on new generation Peer-to-Peer (P2P) technologies characterized by better use of networks resources and ISP friendliness. Peerialism captures more of the large assets of unused computing power and broadband connections whilst at the same time being beneficial to ISPs by reducing network traffic. Peerialism is now launching a P2P streaming solution for content owners.

These are academic papers and articles produced by the members of the Peerialism team.   Title Author Date Description or abstract Cloud computing - gå på moln eller tankar i det blå Gabriel Sandberg March 2, 2009 Cloud computing has for the past few years been a buzz word. The advantages are supposedly undeniable. Many companies provide advanced services based on cloud computing which is said to increase efficiency and security at the same or lower cost. Some claim that it is a new way to relate to the Internet, perhaps even to data management overall. This is an attempt to describe what differentiates cloud computing from other phenomena, to give an overview of a number of ongoing debates, and to propose plausible future developments. (In Swedish.) NATCracker: NAT Combinations…
