Fair bandwidth allocation and congestion control is an important issue when accessing a common shared link in the modern TCP/IP networks. In this paper, we propose and evaluate fair downlink bandwidth distribution method which is based on online upstream control and limitation. The method is designed to maintain the fair shared bandwidth allocation by adaptively controlling the upload rate of the...
In this paper the authors have investigated the performance improvement in long reach optical access system with hybrid optical amplifiers. The apparent options of optical amplification in wavelength division multiplexing systems include the distributed Raman amplifiers, erbium doped fiber amplifiers, and semiconductor optical amplifiers. In our case distributed Raman amplifier is located at the mid-span...
Actual Connection Admission Control (CAC) realization inside the resource reservation protocol — traffic engineering extension (RSVP-TE) in Multiprotocol Label Switching (MPLS-TE) networks does not provide the ability of effective decision making. The actual threshold CAC lacks the capability of taking into the consideration possible application QoS requirements and network QoS potentialities. This...
The ITU-T defined next generation network (NGN) architecture designates the resource admission control function to perform the application-driven Quality of Service (QoS) control across access and core networks. The Generalized Multiprotocol Label Switching (GMPLS) was introduced by the Internet Engineering Task Force (IETF) to cope with new traffic engineering challenges in fast optical networks...
