  • Error Behaviour in Optical Networks Laura Bryony James
    Error Behaviour in Optical Networks Laura Bryony James Corpus Christi College This dissertation is submitted for the degree of Doctor of Philosophy 30th September 2005 Department of Engineering, University of Cambridge This dissertation is my own work and contains nothing which is the outcome of work done in collaboration with others, except as speci¯ed in the text and Acknow- ledgements. Abstract Optical ¯bre communications are now widely used in many applications, including local area computer networks. I postulate that many future optical LANs will be required to operate with limited optical power budgets for a variety of reasons, including increased system complexity and link speed, low cost components and minimal increases in transmit power. Some developers will wish to run links with reduced power budget margins, and the received data in these systems will be more susceptible to errors than has been the case previously. The errors observed in optical systems are investigated using the particular case of Gigabit Ethernet on ¯bre as an example. Gigabit Ethernet is one of three popular optical local area interconnects which use 8B/10B line coding, along with Fibre Channel and In¯niband, and is widely deployed. This line encoding is also used by packet switched optical LANs currently under development. A probabilistic analysis follows the e®ects of a single channel error in a frame, through the line coding scheme and the MAC layer frame error detection mechanisms. Empirical data is used to enhance this original analysis, making it directly relevant to deployed systems. Experiments using Gigabit Ethernet on ¯bre with reduced power levels at the receiver to simulate the e®ect of limited power margins are described.

Unfortunately, the actual performance of the it is a challenge for CPUs to scale with increasing network network does not scale with the increases in line speed. This speeds [2]. In order to overcome this issue, many works on is due to the fact that the majority of packets are less than or equal to 64 bytes and the fact that packet size has not scaled with high performance networks, as in [3] and [4], have advocated the increases in network line speeds. This causes a greater and the use of a larger MTU length or jumbo frames. These works greater load to be placed on routers in the network as routing show that the performance of TCP and the network in general decisions have to be made for an ever increasing number of can significantly improve with the use of jumbo-sized packets. packets, which can cause increased packet delay and loss. In Unfortunately, the benefits of jumbo frames are limited for order to help alleviate this problem and make the transfer of bulk data more efficient, networks can support an extra large several reasons. First, the majority of packets transferred are MTU size. Unfortunately, when a packet traverses a number of 64 bytes or less.

  • Analysis and Optimisation of Communication Links for Signal Processing Applications
    Analysis and Optimisation of Communication Links for Signal Processing Applications ANDREAS ÖDLING Examensarbete inom elektronik- och datorsystem, avancerad nivå, 30 hp Degree Project, in Electronic- and Computer Systems, second level School of Information and Communication Technology, ICT Royal Institute of Technology, KTH Supervisor: Johnny Öberg Examiner: Ingo Sander Stockholm, November 12, 2012 TRITA-ICT-EX-2012:287 Abstract There are lots of communication links and standards cur- rently being employed to build systems today. These meth- ods are in many way standardised, but far from everyone of them are. The trick is to select the communication method that best suit your needs. Also there is currently a trend that things have to be cheaper and have shorter time to market. That leads to more Component Off The Shelf (COTS) systems being build using commodity components. As one part of this work, Gigabit Ethernet is evaluated as a COTS-solution to building large, high-end systems. The computers used are running Windows and the pro- tocol used over Ethernet will be both TCP and UDP. In this work an attempt is also made to evaluate one of the non-standard protocols, the Link Port protocol for the TigerSHARC 20X-series, which is a narrow-bus, double- data-rate protocol, able to provide multi-gigabit-per-second performance. The studies have shown lots of interesting things, e.g. that using a standard desktop computer and network card, the theoretical throughput of TCP over Gigabit Ethernet can almost be met, reaching well over 900 Mbps. UDP performance gives on the other hand birth to a series of new questions about how to achieve good performance in a Windows environment, since it is constantly outperformed by the TCP connections.

  • Jumbo Frames
    Ethernet Jumbo Frames Version 0.1 November 12, 2009 Contributors: Dell: Robert Winter, Rich Hernandez, Gaurav Chawla Cisco: Anthony Faustini, Carl Solder, Thomas Scheibe 3Com: David Law, Siamick Ayandeh Applied Micro: Brad Booth Ethernet Alliance: Blaine Kohl NetApp: Charlie Lavacchia Force 10: Subi Krishnamurthy, Raja Karthikeyan Intel: Eric Multanen Qlogic: Manoj Wadekar Ethernet Alliance | 3855 SW 153rd Drive | Beaverton, OR 97006 www.ethernetalliance.org November 12, 2009 1 Motivation This paper is intended as a resource to help better understand what Jumbo frames are, the implications of their use and the types of applications which drive their use. It is also recognition that Jumbo frames aren’t going away…. What is a “Jumbo” Frame? An Ethernet frame is defined as that unit of packetized formatted information which includes the Ethernet header, payload and Cyclic Redundancy Check (CRC) trailer. It is enclosed by the Start-of-Frame-Delimiter (SOFD) and the Inter-Frame-Gap (IPG) as shown in Figure 1. Note that the payload represents all the information enclosed by the Ethernet header and the CRC. The largest possible payload in a frame is called the Maximum Transmission Unit (MTU). The original IEEE 802.3 specifications (Reference 2) defined a valid Ethernet frame size from 64 to 1518 bytes. The standard Ethernet header is 18 bytes in length and therefore the payload for a standard frame ranges in size from 46 to 1500 bytes. Since the original Ethernet specification was defined various IEEE standards have been developed that support additional, expanded frame types listed below and shown in Figure 1. The support for an additional 4 bytes in the Ethernet header for VLAN tagging (IEEE 802.1Q) increases the maximum Ethernet frame size to 1522 bytes.
