| Information Extraction From Voicemail This paper addresses the problem of extracting key pieces of information from voicemail messages, such as the identity and phone number of the caller. This task differs from the named entity task in that the information this paper is interested in is a subset of the named entities in the message, and consequently, the need to pick the correct subset makes the problem more difficult. Also, the caller's identity may include information that is not typically associated with a named entity. This paper presents three information extraction methods, one based on hand-crafted rules, one based on maximum entropy tagging, and one based on probabilistic transducer induction. It evaluate their performance on both manually transcribed messages and on the output of a speech recognition system. |
| Kushiro City Hospital, Japan, Selects Allied Telesis to Provide a Powerful Controlled Access Network in a Medical Environment In addition to an increase in traffic, when Kushiro Hospital expanded its facilities, the number of services it provided also markedly increased. These expansions meant that the network capabilities required by the hospital went well beyond increased bandwidth - the hospital required a highly reliable, resilient and scalable network infrastructure that would enable them to add future capabilities as and when they were required. Kushiro Hospital turned to Allied Telesis. A SwitchBlade 4004 switch was introduced at the core of the network. A multi-layer modular switch, SwitchBlade met the primary requirements of the project due to its high reliability and flexible scalability, and its ability to incorporate the potential future expansion requirements. |
| Voice Architectures and Deployment Models As companies migrate from traditional telephony to Voice over IP (VoIP), there are more design decisions to make when choosing the most appropriate implementation type. The choices include variations of centralized or distributed architectures, as well as a choice of call control protocols. This Cisco training white paper explains some of the choices and their pros and cons. |

| Deploying CWDM to Overcome Bandwidth Limitations of FTTH Access Networks FTTH networks in North America are being built using various PON architectures fed from a common backhaul. As networks grow in terms of geographic reach, subscriber counts and the scope and number of services offered, Coarse Wave Division Multiplexing (CWDM) has clearly become the preferred method for increasing the bandwidth of these optical access networks quickly, simply and at lowest cost. Passive CWDM requires absolutely no electrical power and the technology has proven itself to be sufficiently robust and reliable for installation in the most demanding environmental conditions. Products recently released to the market allow enhanced flexibility in terms of network planning and installation while preserving scalability to handle far higher data transmission volumes as bandwidth needs expand. |
| Protection Networking of Ethernet PON FTTH Access Network Massive deployment of FTTH fiber network causes protection to FTTH network a crucial need. Most FTTH access networks are protected from failure by having redundant network equipments. These are not economical approaches, as the redundant systems are not efficiently utilized by the network. In this paper, the authors propose a protection method where redundant equipments are not required and protection is provided to end user through sharing of bandwidth during the failure time. A protection control unit and an optical switch is employed connecting four Optical Line Terminations (OLTs) with each one serving only 32 Optical Network Units (ONUs). |
| Protected Ethernet Rings for Optical Access Networks This paper proposes a centralized link layer architecture for providing low latency fault recovery for optical access rings. This architecture exploits the naturally uneven breakdown of network management responsibilities between the components of an access ring. Important administrative operations like ring status checking, fault detection and recovery are aggregated at the HUB component located in the Central Office of the access network. Consequently, when compared with a standardized Rapid Spanning Tree Protocol implementation, the design of the proposed architecture benefits from a simplified link layer design of the Optical Network Unit, in addition to a significantly reduced fault recovery delay in the ring. The paper also presents an Ethernet-based protocol that realizes the centralized protection model. |
| On Assuring QoS in Ethernet Access Network This paper deals with the problem of assuring strict QoS guarantees for the end to end connections that originate from Ethernet access network. It shows that despite high link capacities in some cases Ethernet network might be the reason of QoS deterioration. The primary reason is the lack of appropriate QoS differentiation and traffic isolation mechanisms. The shared buffers and priority schedulers available in most of Ethernet switches appear to be not sufficient to guarantee strict QoS. For these cases new solution is proposed which relies on additional traffic control mechanisms available in other network elements. Only additional mechanism supporting typical functionality of Ethernet switch can provide strict QoS guarantees what was verified in simulations studies. |
| Access Over Ethernet: Insecurities in AoE This paper investigates the insecurities present in the ATA over Ethernet (AoE) protocol. It is clear that this protocol has been designed with ease and simplicity as its primary focus, and as such there are security concerns which require understanding before AoE is used with critical information. ATA over Ethernet (AoE) is an open standards based protocol that allows direct network access to disk drives by client hosts. It has been developed by Coraid ("The Linux Storage People") as a SAN technology and it has been adopted for use by many Universities and US Government agencies. |

| Comparison of MPLS- and IP-Based Transport in Future RANs Under Varying QoS Requirements The paper provides a proposal for an MPLS-based transport network for future Radio Access Networks (RANs) and compares this with a regular IP-based transport network. The MPLS-based approach takes into account the specific needs of current and future RANs especially with respect to QoS requirements and flexibility. The paper compares the MPLS-based solution with a regular IP-based network. The simulation studies based on an extension of the network simulator 2 shows that MPLS is able to fulfill the requirements of future RANs and vastly outperforms a regular IP-based solution. MPLS is able to deliver very stable figures for delay, jitter and packet loss even if the traffic mix within the network changes, which is not the case for an IP-based radio access network. |
| Coca-Cola Enterprises Accelerates Executive Communications Coca-Cola Enterprises (CCE) began as an amalgamation of different independent bottling companies. Coca-Cola Enterprises wanted to quickly communicate company's new strategic direction and develop common vocabulary to ensure consistency of messaging. The challenge was to enable CEO to create personal connection with employees. As a solution the company developed internal executive communication strategy and roadmap, deployed Unified Communications solution and used live video, video on demand, audio, broadcast voicemail, and e-mail. |
