This paper proposes a load balancing algorithm using fuzzy logic so that maximum Quality of Experience can
be achieved. Avoidance of congestion is one of the major performance objectives of traffic engineering in
MPLS networks. Load balancing can prevent the congestion caused due to inefficient allocation of network
resources. Another aspect of the network performance is Quality of Experience (QoE). QoE in
telecommunications terminology, it is a measurement used to determine how well that network is satisfying the
end user's requirements. The Mean Opinion Score (MOS) is an important factor in determining the QoE. MOS
is a measurement of the quality delivered by the network based on human perception at the destination end.

Mobile IPv6 based Mobile Networks are becoming increasingly important with the widespread
popularity of wireless internet connectivity. For large networks, an extension, namely, the Hierarchical
Mobile IPv6 is used, which suffers from overloading of the Home Agent as every packet sent has to pass
through it and this produces a significant loss in performance. In this paper, a method to improve the
mobility using the fast handover of Mobile IPv6 (FMIPv6) and the Reverse Routing Header Protocol is
proposed. Simulation results at different packet intervals show that, the proposed scheme is able to
reduce the average delay and achieve an optimum level of throughput.

Enterprise or campus networks are usually large in size and are difficult to manage. Network administrators are required to frequently perform deliberate changes according to the organizational needs. VLANs are broadly used in enterprise or campus networks to improve scalability, flexibility, ease of management, and to reduce broadcast. Therefore it’s providing layer_2 security as it limits the number of the broadcast domains. Nowadays in this fast-growing industrial age, every company needs the speed of data transfer from one network to another network in manufacturing to cope up with the customer’s requirements. The basic objective of our project is to develop a versatile and low-cost INTER-VLAN-ROUTING which can be utilized in any industry or campus to eliminate this problem. INTER VLAN increases the performance of the network by providing flexibility to the users to log in to any network within the same group without changing their IP address. This also reduces complexity and it also cost-effective
Route Optimization (RO) in Mobile Internet Protocol
Version Six (MIPv6) is a technique that enables a
Mobile Node (MN) and a Corresponding Node (CN)
to communicate directly by bypassing the Home Agent
(HA). RO is usually faced with the problem of Internet
Protocol (IP) multilayer tunnels due to pinball or suboptimal
routing. The generic consideration in
designing route optimization scheme is to use
minimum signaling information in the IPv6 packet
header. In order for optimization to take place in
MIPv6, a protocol called route optimization protocol
must be introduced. Route optimization protocol is
used basically to improve performance. Also RO can
also be described as a mechanism that eliminates the
inefficiency in tunneling of packets from MRs to their
HA before being sent to CNs over the Internet.
However, Network Mobility (NEMO) can be described
as a network whose point of attachment to the Internet
varies with time.
The tradeoff between the two protocols can provide a
significant impact on the networks. Furthermore, one
potential choice of selecting any of the protocols can
increase or decrease the degree of application in used.
The tradeoff in offloading solution can vary from
mobile access network and core mobile network.
Optimizing traffic breakout and support for mobility
are paramount to service operators. The study focused
on the development and evaluation of an experimental
test bed of route optimization in MIPv6 and
NEMO.The tradeoff between the two protocols was
examined. The results of the experimental test bed
shows the benefit of next generation of Internet
system, especially for real-time applications that
need to provide seamless connection with low handoff
latency.

Performance Evaluation of a Layered WSN Using AODV and MCF Protocols in NS-2csandit
In layered networks, reliability is a major concern
as link failures at lower layer will have a
great impact on network reliability. Failure at a l

CF is
developed using
polynomial time
approximation algorithms for the failure polynomial
. Both protocols are compared in terms of
different network parameters such as throughput, pa

shown that the network reliability is better when M
CF protocol is used. It was also shown that
maximizing the min cut of the layered network maxim

Cross layer design for power control and linkIJCNCJournal
Frequent changes in network topology due to mobility and limited battery power of the mobile devices are the key challenges in the adhoc networks. The depletion of power source may cause early unavailability of nodes and thus links in the network. The mobility of nodes causes frequent routes breaks and adversely affects the required performance of the applications. We propose a cross layer design for the dynamic power control protocol and link prediction (DPCPLP) that provides a combined solution for power conservation as well as link availability. This combines the effect of optimum transmit power and received signal strength based link availability estimation with AODV routing protocol using cross layer approach.
This method proposes to use optimum transmit power for transmitting the packets to a neighboring node to
increase the battery life of adhoc nodes and received signal strength based link prediction to increase the
availability of the links. In this paper, the transmit power and received signal strength of the packets are
cross-layer interaction parameters to provide the combined solution for power conservation and reliable
route formation with increased availability of links and thus the routes amongst sources and destinations. Further, this increases network and nodes’ lifetime and capacity. It improves throughput and packet delivery ratio by spatial reuse, prior prediction of link breaks and initiating the route repair. It also reduces
end-to-end delay and power consumption by use of optimum transmit power. Through simulations, we have
shown that our proposed protocol shows better performance.

In Wireless Sensor Network (WSN), QoS (Quality of Service) in sensor application plays a very important
role. QoS based routing is required to ensure the best use of nodes in WSN. In this paper, a comparative
study of QoS based routing in Media Access Control (MAC) protocols are presented based on the traits to
solve problems like prioritization, timeliness, reliability etc. The study mainly focuses on some priority
based QoS protocols used in WSN and a comparison among them. The study reveals that among the five
mentioned protocols; QMAC, PRIMA, DB-MAC, RAP, GTS; PRIMA shows the best performance in the
category of Packet Prioritization, Scheduling Scheme, Queue Type, Energy Awareness and QoS.
Active Network is a novel approach of networking to mobile users in which the nodes are programmed to perform custom operations on the messages that pass through the node. It provides an architectural support for dynamically deploying new protocols in an existing network topology. The routers in an active network can download and execute code that is contained in the packets passing through them, thus rendering the node recognized and run totally new protocols without making any changes to the architecture of the network. Because the network's behavior can be altered at any time, active networks could be used to provide dynamic quality of service (QoS) or to support dynamic solutions to traffic congestion. This research implements and tests such specialized Active Networks security service known as the firewall and the ping service in Active Network. Active Network environment will be implemented on a small scale test scenario in order to study the performance and characteristics of active networks

Multi port network ethernet performance improvement techniquesIJARIIT
An Ethernet has its own importance and space in network subsystem. In today’s resource-intensive engineering the
applications need to deal with the real-time data processing, server virtualization, and high-volume data transactions. The realtime
technologies such as video on demand and Voice over IP operations demand the network devices with efficient network
data processing as well as better networking bandwidth. The performance is the major issues with the multi-port network
devices. It requires the sufficient network bandwidth and CPU processing speed to process the real-time data at the context.
And this demand is goes on increasing. The new multi-port hardware technologies can help to improvements in the
performance of the virtualized server environments. But, these hardware technologies having their own limitations in terms of
CPU utilization levels and power consumption. It also impacts on latency and the overall system cost. This thesis will provide
the insights to some of the key configuration decisions at hardware as well as software designs in order to facilitate multi-port
network devices performance improvement over the existing infrastructure. This thesis will also discuss the solutions such as
Virtual LAN and balanced or symmetric network to reduce the cost and hardware dependency to improve the multi-port
network system performance significantly over the currently existing infrastructure. This performance improvement includes
CPU utilization and bandwidth in the heavy network loads.

As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Evolving Network Demands
We are living in an information age where the interaction among organizations, their
employees, and their customers is continuously evolving. Organizations are communicating
with their customers using tools such as eCommerce, e-mail, YouTube, and video
conferencing-- making a reliable network and high-performance infrastructure key business
enablers. Disruption to this key infrastructure leads to lost productivity and in turn, loss
of customer confidence and revenue. Furthermore, today’s organizations demand flexible
network infrastructures capable of handling ever-increasing data traffic and optimized for
virtualization technologies to deliver a wide range of on-demand services.
The Brocade®
One™
architecture is designed to help these organizations transition smoothly
to a world in which information and applications can reside anywhere. Multi-Chassis Trunking
(MCT) is a key Brocade technology enabling this network architecture. It helps organizations
build scalable and resilient network infrastructures for tomorrow, so that they can continue
to leverage their existing assets and still establish new standards for uptime with the
introduction of future-proof technologies.
Layer 2 networks are ubiquitous in Metropolitan Area Networks (MANs), in the data center,
and in enterprise network infrastructures. These networks are dependent on loop prevention
protocols such as Spanning Tree Protocol (STP) and variations. However STP protocols
suffer from many drawbacks, the most significant being slow convergence and lack of load
balancing on redundant paths. They operate by blocking ports and create unused capacity in
the network.
Network architects have overcome slow convergence using technolog.ies such as Virtual
Switch Redundancy Protocol (VSRP), Metro Ring Protocol (MRP), and Ethernet Ring Protection
(ITU G.8032), all of which offer sub-second convergence. However, they works on the
same link-blocking technology and do not provide the desired active-active load balancing.
The onus of efficient network operation lies with the network architect and advance
planning using load balancing on a per-VLAN basis. Further, the network operator needs to
continuously monitor the network to rebalance.
IEEE 802.1AX Link Aggregation (LAG) technology has solved this using multipathing at Layer
2 and flow-based load balancing. However, the protocol constrains the network to a node-to-
node topology. Organizations require a Layer 2 multipath solution that can provide dynamic
flow-based load balancing to multiple network nodes. Brocade MCT is designed to address
these requirements for today’s resilient and high-performance networks.

MCT Overview
Multi-Chassis Trunking is technology that allows multiple switches to appear as single
logical switch connecting to another switch using a standard LAG. Since the technology is an
enhancement to the standard LAG protocol, a single MCT-unaware server or switch using a
standard LAG trunk can connect to two MCT-aware switches--and the traffic is dynamically
load balanced.
MCT inherits the all benefits of LAG by providing multiple physical links to act as a single
logical link; the new bandwidth available is an aggregate of all the links in the group. The
traffic is shared across the links in the group using dynamic flow-based load balancing and
traffic is moved to a remaining link group in tens of milliseconds in the event of a failure in
one of the links. While standard LAG provides link- and module-level protection, MCT adds
node-level protection, while maintaining failover times better than sub-200 milliseconds for
uplink failure. Further, it works with existing switches and servers that connect to MCT and
does not require any rip-and-replace of existing infrastructure.
MCT is available on all Brocade NetIron®
XMR, CER, and CES and Brocade MLX and MLXe
Series platforms.
MCT Operation
MCT is designed to achieve the desired active-active topology and efficient Layer 2
multipathing, while ensuring that the network scales effectively. Hence the load on the Inter-
Chassis Link (ICL), the link connecting the MCT peers, is kept to a minimum and the protocol
relies on direct forwarding of traffic to the client wherever possible. To understand how MCT
functions, the following sections explain the key elements of MCT.
MCT Elements
MCT peers.• A pair of MCT nodes that appear as a single logical node. A LAG from a
server or a switch can be spread across the MCT peers and they will appear as a single
logical endpoint.
MCT client.• A switch or server connected to the MCT peers using a LAG. The client
device is only required to support IEEE 802.1AX LAG; it could be static or dynamic using
Link Aggregation Control Protocol (LACP). In a multi-tier topology, the client could be a
pair of MCT devices.
Inter-Chassis Link (ICL).• A physical link or a LAG group connecting the two MCT peers.
ICL is an important link and it is recommended as a LAG group for protection against link
or module failure.
Keep-alive VLAN.• An optional VLAN for continuity check messages and failure handling
in the event of ICL failure.

MCT functionality can be divided into to two main parts: LAG operation and Cluster
Communication Protocol (CCP). MCT clients perform only the LAG operations defined in IEEE
802.1AX. The LAG can be a static or a dynamic LACP trunk. Cluster Communication Protocol
is a reliable protocol that runs between the MCT peers over the ICL, and it maintains state
and MAC table synchronization between the two peer nodes.
The network design and configuration is fairly simple. Each MCT peer and client is assigned
a unique ID, known as the RBridge ID. The MCT peer nodes are connected using an ICL and
configured as a cluster. Once the peering relationship is established between the two nodes,
CCP runs over them to make them appear as a single logical node for LAG purposes. Adding
a client is Justas straightforward as associating client RBridge ID with the connected port on
the MCT peers. The CCP protocol manages the rest and keeps the network operation simple.
Traffic from the client is load balanced using a hashing algorithm over the LAG ports. The
MCT nodes forward the traffic to the destination directly. The CCP ensures that the MAC table
between the two nodes is always synchronized, hence in steady state, and ICL use is kept to
a minimum to limit overhead. Downstream traffic on MCT nodes is also directly sent to the
client.
Layer 3 Resiliency
A simple MCT topology addresses resiliency and efficient multipathing in Layer 2 network
topologies. To interface with a Layer 3 network, MCT is configured with Virtual Router
Redundancy Protocol (VRRP) to add redundancy in Layer 3. The standard VRRP mode is
active-standby and all traffic is forwarded through the master. The Brocade NetIron platforms
also support VRRP-E server virtualization (see Figure 2), in which multiple VRRP standby
nodes are supported and each node is capable of forwarding to an upstream Layer 3
network. This provides efficient deployment for both Layer 2 and Layer 3 networks.
Metro Ring Protocol (MRP) was designed to create a scalable, Layer 2, loop-free ring topology
and is a faster alternative to spanning tree protocols. When used with MCT, the MCT peers
act as a logical MCT pair and participate in the MRP ring. The client nodes can then use
standard LAG and achieve active-active dual-homing to the MRP ring. This provides greater
flexibility in network design and helps connect MCT clusters. Typical use cases are dual-
homing in metro networks, as shown in Figure 3, and joining MCT clusters in medium to large
data centers, shown in Figure 4.
Failure Handling
A link or node failure in the MCT network is handled in the same way as a failure in a
standard LAG. In the event of a failure in any of the client links, the client instantly rebalances
the upstream traffic over the rest of the links in a LAG group. Most clients use a hashing
mechanism based on the packet header to ensure that each flow is maintained on a single
link and load balancing occurs on a flow basis.
5. 5
An MCT node with a failed link communicates LAG state change to the peer using CCP. Any
downstream traffic to the client from this node will use the remaining links in the LAG group.
If no alternate client links are available on this MCT node, traffic will be transmitted over the
ICL and use the downlinks on the peer node to ensure traffic delivery. Downstream traffic
arriving on the peer node will be sent directly to the client, just as it would have without the
failure.
The Brocade devices also support Port Loop Detection (PLD), a protocol that can be run along

with other loop prevention protocols to quickly detect and repair loops. Loops are typically
introduced due to network misconfiguration or an errant device in the network. ICL links are
usually configured as a LAG group, which can scale up to 64 x 10 Gigabit Ethernet (GbE) to
provide resiliency and design flexibility. In addition, ICL links are protected with a backup
keep-alive VLAN. This helps the network to continue to function in the unlikely event of
multiple failures, including an ICL failure.
Benefits
MCT helps create a network topology that is easy to configure and manage by eliminating
the need for STP from server to core in a data center. MCT offers five times the improvement
over alternate approaches by providing fast link and node failover times. Stranded network
capacity can be recovered by migrating to MCT and overall network utilization can be
improved by as high as 100 percent. All links from server to core are forwarding traffic and
Brocade’s patent pending hashing algorithms enable efficient link utilization. Further, with
this approach, the network can can appear as a single logical device with over 30 Terabits
per second (Tbps) of switching capacity.
MCT coupled with VRRP-E server virtualization extends these benefits to an upstream Layer
3 network and preserves efficient network utilization even when Virtual Machines (VMs) and
VM mobility are deployed. MCT helps provide investment protection by unlocking the available
bandwidth and seamlessly interoperating with third-party client devices.
In a metro network, MCT allows active-active dual-homing to a pair of access switches,
where the customer edge device needs to support a standard LAG. This can help a service
provider offer more resilient and/or high-bandwidth services than are possible using current
technologies. A majority of metro networks are ring topologies. And MCT can be used in
conjunction with Metro Ring Protocol to offer a resilient and a more efficient network.
Summary
Multi-Chassis Trunking helps organizations build resilient and high-performance network
architectures and allows them to transition smoothly to a world in which information and
applications can reside anywhere. It provides service providers the flexibility to offer new and
differentiated services. The resulting network architectures are fast and reliable and can
scale to meet the needs of customers or applications. A focus on multipathing and efficient
network usage helps contain capital budgets and because it does not use STP, operating
costs can be kept low. Availability of MCT on the Brocade NetIron XMR, CES, and CER and
Brocade MLX and MLXe Series products offers organizations the flexibility to use the right
product for an their specific needs
