Full Stack Solutions
We offer a wide range of tailored solutions for your business needs
CORE BACKBONE
Core Backbone Solutions
Diversified Gateway Berhad has integrated carrier grade solution or technology to offer to service providers or large enterprises for its backbone or transport services over IP, Ethernet, (Packet based) or SONET, SDH, WDM (Optical based).
Packet based solution or technology allows you to confidently offer private line, VPN and advance services on a single integrated backbone. Meanwhile, SONET/SDH are primarily used to support traditional TDM voice and emerging packet solution and additional services which are not supported by packet solution such as Television distribution, Fiber Channel Storage and many installed security systems. These networks can further leverage the bandwidth and distance extensions provided by an underlying DWDM network.
WIRELESS
Wireless Solutions (Point To Point & Backhaul)
Diversified Gateway Berhad also offers high speed broadband wireless from 52Mbps up to 1.25Gbps for both Enterprise LAN and Service Provider mobile wireless network and metro access. The solution is based on FSO (Free Space Optic Technology) and is ideal to deliver the speed of fiber with the flexibility of wireless for connectivity distance between 10m to 5km.
Besides the Free Space Optic technology, wireless solution is also available in digital microwave radio/spread spectrum transmission technology. The said solution caters for both voice and data application over a public or private networks. The advantage of deploying the microwave radio is that it delivers very low bit error rate links that have high immunity to interference.
It can be design to offer point to point and point to multipoint solution from 64kbps up to n x E1 fetching a distance of 50km. The carrier grade microwave radio also incorporate radio links into a fiber based SONET/SDH network delivering speed of STM1 (155Mbps) and above as backhaul infrastructure, access and trunk networks, competitive local access network and enterprise/campus networks.
The applications supported over the wireless network include wireless local loop (WLL), Wide Area Networking (WAN) and Metropolitan Area Networking (MAN). The high performance links offered are ideal for frame relay applications and last mile feeders into optical and satellite networks. The obvious advantages of wireless connectivity are less time consuming and more cost effective as compared to fiber trenching.
ENTERPRISE LAN
Complete Lan (Local Area Network) Solutions
Diversified Gateway Berhad is also focus on delivering a complete LAN solution to its customer in the areas of Structured Cabling and LAN switching (2 tier or 3 tier network topology). The structured cabling encompasses both the horizontal cabling (Cat.5e and Cat.6 UTP cabling) and vertical fiber optic cabling (singlemode and multimode).
The LAN switching covers the areas of layer 2 and layer 3 switching/routing capability enabling VLAN to be effected in the network. Full redundancy of the core network switches is delivered through redundancy in CPU (Processor) and Power Supply and Multi-link trunking architecture to ensure robustness of solution offered. Together with LAN switching, we also provide Network performance monitoring and Bandwidth Management solution that ensure network operation smoothly.Network security solution is highly emphasized with the offering of multi-tiered Firewall architecture and also IDS (Intrusion Detection System) as well as IPS (Intrusion Prevention System) against threats such virus attack, worms and hackers.
Physical encryption devices to encrypt and ensure secured data and voice communication between point to point and multipoint is also available in the form of fax, telephone, mobile phone, modem, leased line, ISDN encryption device with SBLH, 256 bit encryption algorithm.
WAN
Complete Wan (Wide Area Network) Solutions
Diversified Gateway Berhad’s expertise in networking solution includes providing data communication solutions that support several networking technologies such as ATM, Frame Relay, IP and Voice on a single platform or more aptly known as convergence technology.
The technology and solution offers are ideal for both enterprises and service providers for access adaptation or backbone switching. In details, it supports Layer 2 VPN, Ethernet Virtual Private Line Service, Voice transport and networking utilizing ATM transport technologies. In addition, it supports core connectivity and allows revenue generating services as mentioned above to be technically and commercially deployed in the most effective manner.
This is made true with the solution capability of supporting a wide variety of high speed, high density interfaces from DS3 to OC-48 and offer redundancy to meet availability expectations of next generation voice and wireless networks. The services supported under this platform are Intranet services, Internet access, extranets, next-generation wireless networks including TDMA, GSM, GPRS, UMTS, CDMA radio technologies & packet voice networking.
TELCO AND SERVICE PROVIDER
Revenue Generation Solutions For Service Providers
Diversified Gateway Berhad’s expertise in networking solution includes providing revenue generating solution to service providers in the area of Storage Area Network (SAN) for mission critical customers especially in the financial industry where business continuity is of utmost importance in the event of crisis. This service can be delivered via the DWDM technology.
The optical network technology and solution offered will also enable service provider to offer data, VOIP (Voice over IP), voice and multimedia centric application, broadcast, IP Video, Ethernet VPN and even broadband solution via readily infrastructure.
Diversified Gateway Berhad is uniquely qualified not only to deliver the complete set of network transport technologies but also focused on delivering a complete portfolio of profitable services such as Ethernet Private Line and Ethernet VPNs.
NETWORK SECURITY
Network Security Solutions
Information technology (IT) and enterprise networks have become the core of many organizations. Critical business functions often depend on a fully functioning IT infrastructure: no network means no ability to generate revenue. To this end, an organization’s growth and evolution should be reflected in the growth and evolution of its network. Organizational changes can include new or expanded missions, new factors such as mobile workers, and growth or downsizing in response to purely external factors. Infrastructure changes that stem from these factors can include additional network components (of a type already present), new types of components, and additional subnets or Internet connections.
Secure infrastructure design can be a tricky proposition, but a methodical approach to planning will pay dividends in implementation. The first step is a thorough evaluation of the organization’s current and potential business needs and assets, grouped by mission, capability, and requirements. The network design should support compartmentalization of information, and should allow room for expansion as the organization grows. Mission and security requirements can change rapidly and should be re-evaluated on a regular basis; once a month would not be too often. Personnel should keep abreast of industry developments: new technologies may be helpful in solving old problems. Finally, the two principles of risk management are a good yardstick for evaluating proposed changes to a mission-critical infrastructure.
Example of a typical Network Design for Security:
Here is a hypothetical large corporation. The mission is complex, and so is the layout of the network. Dual Internet connections provide redundancy for business continuity. Each connection has its own screening router and firewall, and the external web server is on its own appropriately filtered router interface. Behind the firewalls are the premise routers, where each workgroup is connected using its own—again, appropriately filtered—interface. This means, for example, that the chemistry group’s access to the IT group’s segment can be controlled in a broad fashion. Note the additional firewall between the two premise routers. This firewall controls the type of access that the upper workgroups may have to the lower workgroups’ resources, and vice versa. Using a compartmented approach to the application of technology, this organization can control access to its many assets.
