Next Generation Ethernet Access Networks: GPON vs. EPON
نویسندگان
چکیده
Recently both ITU and IEEE have standardized solutions for Passive Optical Networks operating at gigabit per second line rates and optimized for the transport of packet-based traffic to improve the efficiency of previously standardized broadband PONs, which were based on ATM. The efficiency and performance of PON systems, depends mainly on the implemented medium access protocol. The latter is not part of the standards and left to the implementer, however the standards describe a set of control fields that constitute the tool-set for the MAC operation. In this paper we compare the efficiency and performance of the two systems under as close as possible MAC. Key-Words: Passive Optical Networks, Broadband Access Networks, MAC protocol, Last mile

Capacity and Delay Analysis of Next-Generation Passive Optical Networks (NG-PONs) - Extended Version
Building on the Ethernet Passive Optical Network (EPON) and Gigabit PON (GPON) standards, Next-Generation (NG) PONs (i) provide increased data rates, split ratios, wavelengths counts, and fiber lengths, as well as (ii) allow for all-optical integration of access and metro networks. In this paper we provide a comprehensive probabilistic analysis of the capacity (maximum mean packet throughput) a...

Standardized in 2004, EPON has emerged as a highly successful technology – 3 million lines has been deployed in less than 2 years. The next generation of EPON will bring 10 Gb/s bandwidth to access networks. 1 Brief history of EPON In 2003, the Ethernet protocol celebrated its 30th birthday. All these years it has been adapting and evolving to become the very inexpensive and ubiquitous networki...
متن کاملA Dynamic Bandwidth Allocation Algorithm in Epon Networks
With the rapid development of Internet technology, there have been many new services which require high bandwidth. EPON (Ethernet Passive Optical Network) has become one of the best technologies in the next generation broadband access network because of their high-bandwidth and low-cost. Dynamic bandwidth allocation (DBA) is one of the most critical issues in EPON network. In this paper, a new ...

Recently both ITU and IEEE have standardized solutions for passive optical networks (PONs) operating at gigabit per second line rates and optimized for the transport of packet-based traffic to improve the efficiency of previously standardized broadband PONs, which used the ATM cell as the data transport unit. The efficiency and performance of PON systems depend on the transmission convergence l...
متن کاملParnian: a Two-stage Nested-auction for Dynamic Bandwidth Allocation in Ethernet Passive Optical Networks
One of the key challenges in next generation access networks based on Ethernet Passive Optical Network (EPON) technology is Dynamic Bandwidth Allocation (DBA) process. In this paper we have proposed ‘Parnian’, a two-stage nested-auction for dynamic bandwidth allocation management in Ethernet Passive Optical Networks. In the proposed ‘Parnian’ method, by running nested auction, based on EPON arc...
