With the development of Mobile IPv6 and multicast technology, mobile multicast becomes a research hotspot. Based on two basic mobile multicast methods, the Bi-directional Tunnel (BT) method and the Remote Subscription (RS) method, some mobile multicast schemes have been proposed. However, most of them evaluate the performance by means of analysis and simulation, but lack of testing the performance...
Software as a service (SaaS) is an important technology innovation as well as a business model innovation to bring new opportunities to small and medium enterprises (SME). There are different SaaS provisioning methods, depending on the customer profile, the cost of the required resources, and the price that customers are willing to pay. The core technology of SaaS-ization focuses on multi-tenancy,...
Source address authentication is very important to change current serious network security situation. In this article, we propose a new source address validation scheme based on IBS algorithm and study its security using SVO logic. We find that our scheme can successfully guarantees authenticity of IP packetpsilas information source.
Passport is a new secure and adoptable source address validation technique, which has attracted fully attention. In this article, we research into the efficiency of Passport. First of all, we build a mathematical model to describe Passportpsilas function, then propose an evaluating indexes, at last we use Brite generate a Power-Law network topology and design correlative algorithm to quantitative...
While most of the research work on BGP has focused on detecting and characterizing large-scale routing anomalies from the perspective of network operations and management, it is important to monitor the management actions taken by the network operators in response to global BGP network failures. A fundamental question to answer is the following: by utilizing only public BGP observation data under...
TCP Veno was recently proposed to eliminate TCP performance suffering in the wireless networks. Real network and live Internet measurements have validated Veno's significant performance improvement over Reno. In this paper, we revisit Veno's state distinguishing scheme, and give a detailed study of Veno's performance when three different recovery schemes: Partial ACK, SACK and PACK, are incorporated...
