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:

  1. Access Point- Outdoor or Indoor.
  2. WLC-Wireless Access Controller.
  3. Layer-2 Switch- For aggregating all the AP’s in single hotspot.
  4. Point to Point connectivity till command control center.
  5. Core elements like AAA server, DHCP server, Firewall , Billing system etc.
  6. 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.

Wi-Fi SMP

As part of Phase2 deployment for JDA Wi-Fi following services will be deployed:

  • Free outdoor Public Wi-Fi.
  • Captive Portal.
  • SMS Gateway integration for OTP services.
