Multimedia streaming has recently become a dominant form of Internet traffic. Even in a live streaming environment, however, each end user independently connects to the server by unicast communication. It is thus essential to consider how to provide such services to many users while maintaining efficiency and scalability. To explore the potential of introducing multicast-like transmission mechanisms, we analyze the similarity in streamed data packets that are simultaneously transmitted to several end hosts in real-time video/audio services. The results show a significant level of similarity among the packets and, therefore, that multicast-like mechanisms could decrease streaming traffic.

“…However this paper moves beyond our initial concept of stealth multicast in several key ways. First, the paper in [19] used DSMCast with tree encapsulation as the method for multicast transport. This caused significant overhead to the data packet to be introduced, thus limiting the benefit of stealth multicast.…”

Abstract-As broadband Internet access becomes more widespread, demand for rich multimedia content will increase significantly. When this trend is coupled with the point-to-point nature of the Internet, it is only natural that there will be an increase in redundant network traffic. Hence, a wide variety of techniques have been developed to eliminate redundant traffic in the network ranging from multicast to caching. Multicast techniques suffer from deployment issues, while caching techniques offer limited benefit for data with close temporal proximity (i.e. streaming).In this paper, we present a novel approach, stealth multicast, which offers a practical solution for the adoption of network-level IP multicast. Rather than focusing on a global scale such as with previous approaches, stealth multicast optimizes efficiency on a domain-wise scale. In short, stealth multicast dynamically combines redundant data payloads into virtual groups for multicast transmission across the domain. At the edge of the domain, the packets are converted back to unicast, thus keeping stealth multicast true to its namesake in that neither the user applications nor the external domain are aware of the presence of multicast.The features of stealth multicast allow it to be deployed without requiring changes to the server, client, or external Internet. Furthermore, QoS impact is strictly limited due to controls and the fact that only packets that are known to be likely amenable to multicasting are queued. Finally, stealth multicast allows the economic benefit of multicast to be directable, giving ISPs an incentive to deploy multicast.

“…SMC is a method of converting redundant unicast Internet traffic into efficient multicast packets. This is enabled by the use of a module called a Virtual Group Detection Manager (VGDM) [3]. A VGDM performs similarity analysis on packet payloads and, based on predefined heuristics, caches the packet or forwards it on to its destination.…”

“…In cases such as Asymmetric DSL, the upstream bandwidth is even more constrained than the downstream. Bandwidth conservation techniques such as Application Layer Multicast (ALM) and Stealth Multicast (SMC) [3] are able to reduce these bandwidth demands, but are not compatible with security protocols such as those used in SSL or IPSec. This leaves hosts to choose between security and bandwidth while the situation demands that both exist together.…”

Information security a is constant concern of Internet data. One security solution is IPSec, which is a set of protocols that provides both data confidentiality and authenticity. Another concern is the last mile bandwidth limitation on many Internet connections. This problem can be mitigated by bandwidth conservation techniques such as Application Layer and Stealth Multicast (SMC). Combining IPSec and multicast techniques would be ideal, but is not possible due to the nature of encrypted data and the requirements of multicast messages. We present the concept of a Trusted Security Device (TSD) which provides efficient bandwidth usage while maintaining security levels offered by IPSec. A TSD cooperates with clients and servers while implementing SMC technology. Minor modifications to clients and servers are necessary to enable discovery, key exchange, and communication between clients, servers, and TSDs. TSD technology is applicable to streaming data where confidentiality, authentication, and bandwidth conservation are concerns.
