BGP (Border Gateway Routing Protocol) is a standardized exterior gateway protocol designed to
exchange routing and reachability information between autonomous systems (AS) on the Internet. The
Border Gateway Protocol makes routing decisions based on paths, network policies or rule-sets
configured by a network administrator, and are involved in making core routing decisions.
BGP is a very robust and scalable routing protocol, as evidenced by the fact that BGP is the routing
protocol employed on the Internet.

IP multicast is a method of sending Internet Protocol (IP) datagrams to a group of interested receivers in a single transmission. It is often employed for streaming media applications on the Internet and private networks.(wikipedia)

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

1. EIGRP
Enhanced interior gateway routing protocol
Featuring EIGRP………….
Classless
Cisco proprietary
Autonomous system 1-65536
VLSM
Hybrid
hop count = 255
Support multiple protocols like IP, IPX, Apple
talk, Also IPv6.
2. EIGRP intro
Eigrp is a class les cisco proprietary protocol. It use concept of Autonomous
system to differentiate each part of the network using a specific number
from 1-655536.
It also support the VLSM technique to save more IP`s for an
internetwork.
It is a hybrid routing protocol due to the features of both
the DISTANCE VECTOR+LINK STATE.
Eigrp is not able to send the link state
update packets like the OSPF but it can send the distance vector update
containing the information about the networks.
But EIGRP have some link state
characteristics like it can synchronize the routing tables between the
neighbors at startup and also use TRIGGER update
3. EIGRP intro
Maximum hop counts by the EIGRP is 255.
And it can also route multiple protocols like IP,IPX,APPLE TALK
etc.
It has also the Metrix like
Bandwidth
load
Delay
Reliability
MTU.
Also there is no LOOP control method is required for the EIGRP
4. EIGRP modules..
RTP:- Reliable transport protocol
It is use to create the neighbor ship tables in the
router and Distributing the LSA{( Link state Advertisement) information about
any link to the all connected routers with that interface} .
RTP send a hello packet to
all the neighbors and when the neighbors will reply with acknowledgement
packet then it will create a NEIGHBOUR TABLE.
for the RTP processes the EIGRP use the
Multicast addresses from the D class {224.0.0.9}.
Eigrp maintain the neighbor table of all its
neighbors using the RTP and if there is any router which is not sending any
update about it then RTP use multicast update for that router for 15 times and
if the router will not make any reply then after the 16th update that router is
assumed as unreachable and removed from the neighbourship table
5. EIGRP DUAL
DUAL:- Diffusing Update Algorithm
it is the Algorithm which enables the
EIGRP to use the DISTANCE VECTOR + LINK STATE methods
simultaneously.
like 1.VLSM
2.Backup route are possible.
3.Send route Queries to the neighbors if the
Destination of the received packet is
unknown.
4.Dynamic route Recovery
6. EIGRP terms..
Reported distance:-
it is the Distance between the destination network and the next
hop IP address.
Feasible distance :-
It is the total distance between the destination and our router.
Successor:-
It is the Route with least hop count and listed as the primary
route in the routing table
Feasible successor:-
It is the backup route which can be used in case when the
primary route is not available or failed
7. EIGRP tables
EIGRP use three tables to store the all information's
1. Neighbourship table
2. LSA table
3. Routing table
8. EIGRP tables
1.Neighborship table:-
used to store the information about the routers with whom
neighbor ship relation is found.
2. LSA/Topology table:-
used to store the information about the every device in
every route in the internetwork by the information received from each
neighbor table.
3. Routing table:-
store the Routes which are currently used to store the
routing decisions.
12. EIGRP neighbor explanation
#show ip eigrp neighbor
H Add/interface hold uptime SRTT RTO Q Seq
(ms)
0 192.168.10.6 12 0:31:60 26 200 0 7
H= it indicates in which order neighbor is discovered
Hold= how long this route will wait for hello packet to arrive from the specific
neighbor.
Uptime= for how long the neighbor is connected.
SRTT= process of multicasting and unicasting.
RTO= Retransmission time out= maximum time for which EIGRP waits before
retransmitting a packet to neighbor.
Q= it indicates that my massage is In the queue.
Seq= sequence number of the last update from the neighbor
