Skype Voip Service- Architecture and Comparison Hao Wang Institute of Communication Networks and Computer Engineering University of Stuttgart Mentor: Dr.-Ing
INFOTECH Seminar Advanced Communication Services (ACS), 2005 Skype VoIP service- architecture and comparison Hao Wang Institute of Communication Networks and Computer Engineering University of Stuttgart Mentor: Dr.-Ing. S. Rupp ABSTRACT Skype is a peer-to-peer (P2P) overlay network for VoIP and other applications, developed by KaZaa in 2003. Skype can traverse NAT and firewall more efficiently than traditional VoIP networks and it offers better voice quality. To find and locate users, Skype uses “supernodes” that are running on peer machines. In contrast, traditional systems use fixed central servers. Also Skype uses encrypted media channel to protect the dada. The main contribution of this article is illustrating the architecture and components of Skype networks and basically analyzing key Skype functions such as login, NAT and firewall traversal. Furthermore, it contains comparisons of Skype networks with VoIP networks regarding different scenarios. On that basis it reveals some reasons why Skype has much better performance than previous VoIP products. Keywords Voice over IP (VoIP), Skype, Peer-to-peer (p2p), Super Node (SN) 1. Introduction It is expected that real-time person-to-person communication, like IP telephony (VoIP), instant messaging, voice, video and data collaboration will be the next big wave of Internet usage. VoIP refers to technology that enables routing of voice conversations over the Internet or any other IP network. Another technology is peer-to-peer, which is used for sharing content like audio, video, data or anything in digital format. Skype is a combination of these two technologies. It has much better performance by making use of advantages of both technologies. -

Insight Into the Gtalk Protocol
1 Insight into the Gtalk Protocol Riyad Alshammari and A. Nur Zincir-Heywood Dalhousie University, Faculty of Computer Science Halifax NS B3H 1W5, Canada (riyad,zincir)@cs.dal.ca Abstract Google talk (Gtalk) is an instant messeger and voice over IP client developed by Google in 2005. Gtalk can work across firewalls and has very good voice quality. It encrypts calls end-to-end, and stores user information in a centralized fashion. This paper analyzes fundamental Gtalk functions such as login, firewall traversal, and call establishment under different network scenarios. The analysis is performed by both active and passive measurement techniques to understand the Gtalk network traffic. Based on our analysis, we devised algorithms for login and call establishment processes as well as data flow models. I. INTRODUCTION Voice over IP (VoIP) is becoming a major communication service for enterprises and individuals since the cost of VoIP calls is low and the voice quality is getting better. To date, there are many VoIP products that are able to provide high call quality such as Skype [1], Google Talk (Gtalk) [2], Microsoft Messenger (MSN) [3], and Yahoo! Messenger (YMSG) [4]. However, few information has been documented about protocol design used by these VoIP clients since the protocols are not standardized, many of them are proprietary, and the creators of these softwares want to keep their information confidential and protect their protocol design form competitors. In this paper, we have generated and captured network traffic in order to determine the broad characteristics of one of the most recent and fast growing VoIP applications, Google Talk. -

Building Large-Scale Distributed Applications on Top of Self-Managing Transactional Stores
Building large-scale distributed applications on top of self-managing transactional stores June 3, 2010 Peter Van Roy with help from SELFMAN partners Overview Large-scale distributed applications Application structure: multi-tier with scalable DB backend Distribution structure: peer-to-peer or cloud-based DHTs and transactions Basics of DHTs Data replication and transactions Scalaris and Beernet Programming model and applications CompOz library and Kompics component model DeTransDraw and Distributed Wikipedia Future work Mobile applications, cloud computing, data-intensive computing Programming abstractions for large-scale distribution Application structure What can be a general architecture for large-scale distributed applications? Start with a database backend (e.g., IBM’s “multitier”) Make it distributed with distributed transactional interface Keep strong consistency (ACID properties) Allow large numbers of concurrent transactions Horizontal scalability is the key Vertical scalability is a dead end “NoSQL”: Buzzword for horizontally scalable databases that typically don’t have a complete SQL interface Key/value store or column-oriented ↑ our choice (simplicity) The NoSQL Controversy NoSQL is a current trend in non-relational databases May lack table schemas, may lack ACID properties, no join operations Main advantages are excellent performance, with good horizontal scalability and elasticity (ideal fit to clouds) SQL databases have good vertical scalability but are not elastic Often only weak consistency guarantees, such as eventual consistency (e.g., Google BigTable) Some exceptions: Cassandra also provides strong consistency, Scalaris and Beernet provide a key-value store with transactions and strong consistency Distribution structure Two main infrastructures for large-scale applications Peer-to-peer: use of client machines ← our choice (loosely coupled) Very popular style, e.g., BitTorrent, Skype, Wuala, etc. -
