The company

News, Okategoriserade

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



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 thousands of concurrent peers while preserving a good degree of accuracy compared to a packet-level simulator.

Paper to be published at the ACM Simutools 2011 Conference (industrial track), Barcelona, Spain, March 2011.

P2P Components

News, Okategoriserade

The P2P Components are tools to build and analyze p2p networks:

MyP2PWorld: A complete P2P network simulator. More information is available here.
Link Assess: Measures the instantaneous quality of any link between two nodes.
Net Topology: A P2P component to help construct a locality aware overlay network.

Network traffic optimization


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.

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.
