Low Level Design Connectivity
The diagram below captures the snapshot aptly of the field connectivity for various solutions
The solution for the proposed architecture encapsulates the following components:
Command Control Center
There will be switches each having 32x10G
SFP+ based ports each acting as Core Switch
placed at JDA NOC. The same core switch
will be used in Phase-2 as well, however 10G
& 1G ports may have to be added in to the
switch to add additional wireless
controllers, NAS storage,10G capable
firewall cum IPS, Communication Severs etc.
Both of these switches are being configured
in HA mode using stack configuration.
There will be two routers acting as internet
router loaded with 1x10G SFP+ based port &
4x1Gig ports. ISP internet links are
terminated into the routers over 1G ports.
There is a set firewall cum IPS device that is
acting as core firewall currently. The current
firewall will be reused to protect the internal
server farm devices.
Firewall with URL Filtering</p>
The number of wireless AP is increasing day
by day to cater to a large area throughout
Jaipur city to provide more & more wireless
connectivity. The more the load on Internet
increases, the more the firewall capacity
needs to be increased. The proposed firewall
will not only provide raw firewalling
capabilities to JDA, it will also have all
capabilities of next Gen firewall, deep packet
inspection & URL filtering capabilities.
It provides comprehensive protection from
known and advanced threats, including
protection against targeted and persistent
malware attacks (Fig 1). The Firewall will
have these comprehensive capabilities:
- Site-to-site and remote access VPN and
advanced clustering to provide highly
secure, high-performance access and
high availability to help ensure business
continuity.
- Granular Application Visibility and
Control (AVC) to support more than
3,000 application-layer and risk-based
controls that can launch tailored
intrusion prevention system (IPS) threat
detection policies to optimize security
effectiveness.
- Reputation- and category-based URL
filtering to offer comprehensive alerting
and control over suspicious web traffic
and enforce policies on hundreds of
millions of URLs in more than 80
categories.
The Firewall will provide the below
capabilities:
- It will provide up to 20 Gbps of
multiprotocol throughput.
- It will provide up to 15 Gbps of
Application Visibility and Control (AVC)
throughput.
- It will provide up to 4 Gbps of IPSec
throughput.
- The combined throughput of AVC &
Next Gen IPS is 15 Gbps.
- It has 2 power supplies & comes with
4x10G SFP+ based ports from day one.
Wi-Fi
In the 2nd phase of this project, two wireless
controllers have been proposed. The current
WLC can support only up to 500 AP; hence
the new WLC that can cater up to 1500 AP
will be used to form a single group with
existing WLC to provide the seamless
movement of AP & users from one AP or
controller to the other. Outdoor AP will be
powered on using external power adaptor &
will be connected to ruggedized switches at
the field level. Additional licenses for MSE
(Mobility Service Engine) to provide WiPS
(Wireless IPS) functionality is also provided.
The Network system is developed based on
the following criteria
- Coverage – to achieve macro WiFi
coverage.
- Capacity – to provide sufficient user
capacity in urban areas
- Mobility – to support users in driving
speed.
- Quality of Service – to support real-time
applications.
- Manageability – to simplify operations
and maintenance of WiFi network.
Key Components:
- Access Point- Outdoor or Indoor.
- WLC-Wireless Access Controller.
- Layer-2 Switch- For aggregating all the
AP’s in single hotspot.
- Point to Point connectivity till command
control center.
- Core elements like AAA server, DHCP
server, Firewall , Billing system etc.
- EMS / NMS: Management system to
control / configure / maintain the
system.
- Access point: Either in controller-based
or standalone operation, provides Wi-Fi
connectivity concurrently to clients on
both 2.4-GHz and 5-GHz radios. As there
will be a centralized controller the DC,
controller-based architecture is highly
recommended.
- Bridging: Provides point-to-point,
high-capacity data links, as well as
point-to-multipoint bridging for
campuses.

The Smart Lighting solution has the
following components that enable the city
to manage and operate the entire lighting
infrastructure centrally along with various
policies.
- LED control node (External Core Node)
- Advanced Multi-sensor nodes.
- Wireless Access Points
Cloud managed Lighting management
software platform
The control node connects to the LED
luminaire through a NEMA connector and
provides power to the LED. It is possible to
have internal or external control nodes
depending on the requirement. An external
node has been proposed in JDA keeping in
mind ease of operation and maintenance.
The control node gets registered to the
Lighting management software platform in
the cloud and is managed and operated
centrally e.g. Predefined ON/OFF/Dimming
control, policy based lighting control or Time
of day scheduled control.
Connectivity
