S#$% My Network Says (CTC Retreat 2010)Gary Wilhelm
In the spirit of the well-known Twitter feed about a dad's view of the world, the campus network actually provides both insightful and perverse findings to the ITS Comm Tech Director of Networking, Jim Gogan. As part of the annual campus network status update, Jim will share many of these findings, all in a G-rated format, as well as what he thinks the network will be telling him over the next year.

Water billing management system project report.pdfKamal Acharya
Our project entitled “Water Billing Management System” aims is to generate Water bill with all the charges and penalty. Manual system that is employed is extremely laborious and quite inadequate. It only makes the process more difficult and hard.
The aim of our project is to develop a system that is meant to partially computerize the work performed in the Water Board like generating monthly Water bill, record of consuming unit of water, store record of the customer and previous unpaid record.

A review on techniques and modelling methodologies used for checking electrom...nooriasukmaningtyas
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.
Harnessing WebAssembly for Real-time Stateless Streaming PipelinesChristina Lin
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.

IEEE 802.5 and Token Ring
• Proposed in 1969 and initially referred to as a
Newhall ring.
Token ring :: a number of stations connected by
transmission links in a ring topology.
Information flows in one direction along the
ring from source to destination and back to
source.
Medium access control is provided by a small
frame, the token, that circulates around the
ring when all stations are idle. Only the station
possessing the token is allowed to transmit at any
given time.
13. Eng & Educator Osama Ghandour
Assiut STEM School
13
Token Ring Operation
• When a station wishes to transmit, it must wait
for token to pass by and seize the token.
– One approach: change one bit in token which
transforms it into a “start-of-frame sequence” and
appends frame for transmission.
– Second approach: station claims token by removing
it from the ring.
• Frame circles the ring and is removed by the
transmitting station.
• Each station interrogates passing frame, if
destined for station, it copies the frame into local
buffer. {Normally, there is a one bit delay as the
frame passes through a station.}
15. Eng & Educator Osama Ghandour
Assiut STEM School
15
Re-inserting token on the ring
Choices:
1. After station has completed
transmission of the frame.
2. After leading edge of transmitted
frame has returned to the sending
station
The essential issue is whether more than
one frame is allowed on the ring at the
same time.
16. Eng & Educator Osama Ghandour
Assiut STEM School
16
IEEE 802.5 Token Ring
• 4 and 16 Mbps using twisted-pair cabling
with differential Manchester line encoding.
• Maximum number of stations is 250.
• Waits for last byte of frame to arrive before
reinserting token on ring {new token after
received}.
• 8 priority levels provided via two 3-bit fields
(priority and reservation) in data and token
frames.
• Permits 16-bit and 48-bit addresses (same
as 802.3).
17. Eng & Educator Osama Ghandour
Assiut STEM School
17
Token Ring
• Under light load – delay is added due to
waiting for the token.
• Under heavy load – ring is “round-robin”
• The ring must be long enough to hold the
complete token.
• Advantages – fair access
• Disadvantages – ring is single point of failure,
added issues due to token maintenance.
18. Eng & Educator Osama Ghandour
Assiut STEM School
18
Token Maintenance Issues
What can go wrong?
• Loss of token (no token circulating)
• Duplication of token (forgeries or mistakes)
The need to designate one station as the
active ring monitor.
• Persistently circulating frame
• Deal with active monitor going down.

27. Eng & Educator Osama Ghandour

FDDI BASIC PRINCIPLE
• TOKEN RING NETWORK LIKE IEEE 802.5
• TOKEN: A SPECIAL SEQUENCE OF BITS
• TOKEN CIRCULATES AROUND THE RING
• A STATION REMOVES THE TOKEN FROM RING
BEFORE TRANSMISSION
• AFTER TRANSMISSION, THE STATION
RETURNS THE TOKEN TO THE RING
• COLLISIONS ARE PREVENTED AS THERE IS
ONLY ONE TOKEN IN THE RING

FDDI ARCHITECTURAL MODEL
• ACCORDING TO THE OSI-RM, FDDI SPECIFIES
LAYER 1 (PHYSICAL LAYER) AND PART OF
LAYER 2 (DATA LINK CONTROL LAYER)
• THE PHYSICAL LAYER HANDLES THE
TRANSMISSION OF RAW BITS OVER A
COMMUNICATIONS LINK
• THE DATA LINK CONTROL (DLC) LAYER IS
RESPONSIBLE FOR MAINTAINING THE
INTEGRITY OF INFORMATION EXCHANGED
BETWEEN TWO POINTS

RELATIONSHIP BETWEEN FDDI AND OSI-RM
34. Eng & Educator Osama Ghandour
Assiut STEM School

THE PMD LAYER
• PMD LAYER DEFINES THE TYPE OF MEDIA
INTERCONNECTION AND ITS CHARACTERISTICS
SUCH AS TRANSMITTER POWER, FREQUENCIES,
RECEIVER SENSITIVITIES, BIT ERROR RATES (BER),
OPTICAL COMPONENTS ETC.
• PMD-MMF: MULTIMODE (62.5 MICRON CORE
DIAMETER) FIBER
• PMD-SMF: SINGLE-MODE (8-10 MICRON CORE
DIAMETER) FIBER
• ALSO DEFINES STP, UTP AS MEDIA AND FDDI ON
SONET
35. Eng & Educator Osama Ghandour
Assiut STEM School
35
THE PHY LAYER
• PROVIDES THE MEDIA INDEPENDENT FUNCTIONS
ASSOCIATED WITH THE OSI PHYSICAL LAYER
• RECEPTION: DECODES THE RECEIVED BIT
STREAM FROM PMD INTO A SYMBOL STREAM FOR
USE BY THE MAC LAYER
• TRANSMISSION: ENCODES THE DATA AND
CONTROL SYMBOLS PROVIDED BY MAC USING
4B/5B ENCODING FOR THE PMD LAYER
• ALSO PROVIDES SMT THE SERVICES REQUIRED
FOR THE ESTABLISHMENT AND MAINTENANCE OF
THE FDDI RING (BY CONTINUOUSLY LISTENING TO
THE INCOMING SIGNAL)
36. Eng & Educator Osama Ghandour
Assiut STEM School
36
THE MAC LAYER
• PROVIDES FAIR & DETERMINISTIC ACCESS
• FAIR: NO NODE HAS ADVANTAGE OVER ANOTHER
IN ACCESSING THE MEDIUM
• DETERMINISTIC: UNDER ERROR-FREE
CONDITIONS, THE TIME A NODE HAS TO WAIT TO
ACCESS THE MEDIUM CAN BE PREDICTED
• MEDIUM ACCESS IS CONTROLLED BY A TOKEN
• TOKEN PERMITS THE NODE THAT RECEIVES IT TO
TRANSMIT FRAMES
• THE MAC LAYER OF THE NODE THAT GENERATED
THE FRAME IS RESPONSIBLE FOR REMOVING THE
TOKEN
37. Eng & Educator Osama Ghandour
Assiut STEM School
37
THE SMT LAYER
• A SOPHISTICATED, BUILT-IN NETWORK
MONITORING AND MANAGEMENT CAPABILITY
• SMT IS NOT AN OSI-RM SPECIFICATION
• MAKING USE OF THE SERVICES PROVIDED BY PMD,
PHY, AND MAC, IT CARRIES OUT MANY FUNCTIONS
SUCH AS NODE INITIALIZATION, BYPASSING
FAULTY NODES, COORDINATION OF NODE
INSERTION AND REMOVAL, FAULT ISOLATION AND
RECOVERY
• SMT IS MOST COMMONLY IMPLEMENTED AS A
SOFTWARE PROCESS RUNNING ON THE FDDI
