Multi Protocol Label Switching. (by Rahil Reyaz)RAHIL REYAZ
MPLS was developed to address some of the disadvantages of IP and ATM routing. It works by assigning labels to packets at the edge of the network which are then used to forward packets across the core. This label switching allows for faster forwarding than IP routing. MPLS can be used to engineer traffic flows, provide virtual private networks, and transport various layer 2 protocols over an IP or MPLS backbone. While it adds complexity, MPLS improves performance and supports quality of service and network scalability.
This document provides an overview of LTE (Long Term Evolution) technology, including its network architecture, modulation techniques, and throughput calculation. It discusses key aspects of LTE such as OFDM, OFDMA, adaptive modulation and coding, MIMO antennas, and the use of SC-FDMA for uplink transmission. Diagrams and equations are presented to illustrate LTE resource blocks, modulation schemes, and how to calculate throughput at the MAC layer for different bandwidths, modulation types, and MIMO configurations. The purpose is to introduce basic concepts of LTE for telecommunications engineering students.
UMTS is the 3G cellular standard proposed by ETSI to evolve GSM and GPRS networks. It uses WCDMA as its air interface and includes the following key aspects:
- A complete system architecture with standardized interfaces to allow interoperability between vendors.
- A UTRAN subsystem comprising Node B base stations and RNC controllers to handle radio functionality using WCDMA.
- A core network subsystem including elements like MSC, SGSN, GGSN to support both circuit switched and packet switched services.
- WCDMA uses CDMA with variable spreading factors to provide different data rates. It employs channelization codes, scrambling codes and modulation like QPSK.
The Siemens SURPASS hiX 5625/5630/5635 is a carrier-grade, Ethernet-based DSLAM platform for providing broadband services over existing copper infrastructure. It supports technologies like ADSL2+, VDSL2, and SHDSL across chassis with 5 to 17 slots. The DSLAMs provide redundancy, security, quality of service, and management features to ensure failure proof access networks.
This document outlines the thesis project of Satya Prakash Rout, a student pursuing an M.Tech in Applied Optics. The project involves emulating different Dynamic Bandwidth Allocation algorithms to monitor the performance of a 10G-EPON network implementing Triple Play. Specific aspects that will be studied include implementing Triple Play with a new scheduling algorithm called TD-Sense, generating different traffic models, comparing the performance of DBA-Gated, DBA-Linear and DBA-Max algorithms, and potential future work involving long-reach PONs and green networking techniques. The document concludes by acknowledging the contributions of the student's guide, advisors and classmates to the successful completion of the project.
