To reduce the memory size and fasten the process of searching for a symbol in a Huffman tree, we exploit the property of the encoded symbols and propose a memory-efficient data structure to represent the Huffman tree, which uses memory nd bits, where n is the number of source symbols and d is the depth of the Huffman tree. Based on the proposed data(More)
It has been demonstrated that as the per-flow product of bandwidth delay increases, TCP becomes inefficient and unstable, regardless of the queuing discipline. By decoupling utilization control from fairness control, the explicit control protocol (XCP) outperforms TCP in both conventional and high bandwidth-delay environments. In this article, we present an(More)
Circuit Emulation Services (CES) technology has emerged as an option to mitigate traditional TDM circuits supporting legacy applications across managed packet networks. Since Ethernet Passive Optical Network (EPON) is becoming a major technology for pervasive access. The primary benefits of CES over EPON (CESoEPON) are the low cost and simplicity of(More)
Ternary content addressable memory (TCAM) is favorable for high-speed search due to its parallel architecture and ability for searching arbitrary-length keys. However, the usage of TCAM is limited because of its high cost and power consumption. This paper introduces a TCAM-based Huffman decoding algorithm for single-side growing Huffman tree (SGH-tree),(More)
Location-awareness computing enables services based on the current location of a user. By adding a layer of location-awareness intelligence to the VoWLAN platform, a location-enabled VoWLAN service may further bring seamless connections for medical professionals to communicate and collaborate with each other efficiently. It significantly aids the locating(More)
With the emergence of Ethernet as a convergence layer in access network, Ethernet Passive Optical Network (EPON) has evolved. It is being considered as a promising solution to the “last mile” problem in next-generation broadband access network. An EPON is a point-to-multipoint tree topology, which carries 802.3 Ethernet frames between an(More)
In the large bandwidth-delay product (BDP) networks, it has been demonstrated that the explicit control protocol, XCP, outperforms TCP and remains efficient, fair, and stable. However, once a packet drop is detected, an XCP's congestion management should follow TCP's Van Jacobson congestion control. In other words, congestion window should be halved and the(More)
inherent problems such as route optimization in these protocols have not been really solved. Although various proposals tried to tackle the route optimization problem, none of them has achieved a real success. Furthermore, most of them are not comprehensive solutions for coexisting MIPv6/PMIPv6 mobile environment. In this paper, we proposed a novel unified(More)
