design of a shared memory carrier ethernet Switch compliant to provider backbone bridging traffic engineering ieee802 1qay
High Performance Switching and Routing, 2012Co-Authors: Saurabh Mehta, Ashutosh Upadhyaya, Sarvesh Bidkar, Ashwin GumasteAbstract:Carrier Ethernet is emerging as a new transport paradigm across metropolitan and core networks. Provider Backbone Bridging-Traffic Engineering or PBB-TE was standardized in the IEEE as 802.1Qay as a mechanism to provide a dedicated transport service at the Ethernet layer. This paper discusses implementation of the PBB-TE standard using shared memory Switch architecture, though the same architecture argument can be extended to implement MPLS-TP (the other manifestation of Carrier Ethernet). While shared memory Switch architectures have been well investigated, we provide to the best of our knowledge the first carrier-class Aggregation Switch implemented in a single Field Programmable Gate Array (FPGA). This low-cost implementation paves the way for advances in Carrier Ethernet technologies to be made available to the access part of the network using rapid prototyping and commercial off the shelf components. The Switch architecture supports multiple QoS levels and implements circuit emulation to transport traditional circuit services over a packet backbone. A rigorous simulation study validates our effort.

A Multicast IPTV Bandwidth Saving Method
2013Co-Authors: Mohamed Moughit, Abdelmajid Badri, Aicha Sahel, Sciences Univ, Leeatilaboratory Fstm, Mohammediauniv Hassan, Mohammedia MoroccoAbstract:IPTV services delivered traditional television channels via IP to customers. IGMP protocol is the control mechanism used to control the delivery of multicast traffic to interested and authorized users. IGMP commands notify the upstream equipment to stop sending (“leave”) one channel or begin sending (“join”) another channel. Depending on the architectural choices, this process occurs in the DSLAM, an Aggregation Switch, or at an edge router. All channels are sent by a multicast source to DSLAM even if no user in the DSLAM has requested it. This leads to sub-optimal use of bandwidth. This paper studies and investigates the performance of IPTV controlled by CGMP Protocol to save bandwidth using OPNET package. It shows that when CGMP is enabled on edge routers and Switches, hosts receive only the channels demanded and therefore the bandwidth is optimized and also the queuing delay is reduced
