Utilizing a dynamic any-to-any platform, GDS provides a completely independent wireless and wired infrastructure, through which organizations can seamlessly and easily integrate multiple platforms and connect their remote sites to their headquarters directly to each other. Those infrastructures allow for network-wide transmission of multi-protocol data by delivering multi-megabit access to local network resources (Intranet). This method serves to significantly improve employee productivity by providing them with real-time and secured access to the organization resources wherever they are located.
These two infrastructures are based on a platform-independent model and do not share any nodes, equipment, or systems; the same NOC manages both infrastructures. The GDS network is designed to accommodate various user needs and to provide different connection types over several links.
We are aware at GDS of the importance of a reliable link to businesses and the negative impact a failure could have on an operation. Therefore, and leveraging the expertise that we have and the two separate networks that we operate, we can offer our customers three grades of protection:
Given the considerable network management expertise gained over the years and its understanding of customers’ requirements, GDS took the initiative in 2013 to fill a pressing market need by further developing its managed service solution to include hosted video service.
In the standard setup, the customer’s location is connected to GDS network through a single
This is the simplest setup and offers the least protection.
In the protected setup, the customer location is connected to two separate GDS nodes in two separate networks. A failure on one of the links does not affect the customer’s service as the branch remains connected to the network through the other link. Only a router failure could interrupt the service. This setup offers a much higher protection than the standard service.
In this setup, the customer location is connected to two separate GDS nodes in two separate networks and each link is terminated on a separate router. This setup offers the same protection as a “Protected” service with the additional protection of having two routers. In case a router fails, the service remains operational through the other link and router. In all these scenarios, the routers can be provided by GDS as part of a Managed CPE Service contract
The GDS wireless microwave network currently serves thousands of connections under Clear Channel, layer 2 Frame Relay, Ethernet over ATM, and IP layer 3 over MPLS protocols. Banks and institutions, within the public, financial, educational, and health sectors rely on these types of services for their interconnection needs. Residential and corporate sectors, commercial ventures, companies, NGOs and service providers also benefit from these GDS solutions.
The GDS network provides different varieties of WAN services, from legacy TDM links to multi-gigabit Ethernet, with a multitude of protocols and topologies.
The table below shows the protocols with respect to the physical links and corresponding throughputs
|Protocol Encapsulations||Physical Link Type||Physical port||Bandwidth|
|HDLC, PPP||Point-to-multipoint or point-to-point link||E1/V.35/X.21||Up to 2 Mbps|
|Frame Relay||Point-to-multipoint or point-to-point link||E1/V.35/X.21||Up to 2 Mbps|
|Ethernet over ATM (RFC 1483)||Point-to-multipoint link||Ethernet||Up to 30 Mbps|
|Metro Ethernet Layer 2 and Layer 3 (10/100)||Point-to-multipoint or point-to-point link||Ethernet||Up to 1Gbps|
In a historic agreement with the Ministry of Telecommunications, GDS launched across Lebanon its advanced DSL access network in the context of local-loop unbundling. Alcatel-Lucent (Euronext Paris and NYSE: ALU), the undisputed world leader in DSL networks, supplied the CO (central office) equipment, which supports a variety of modes, such as ADSL 2+, Reach ADSL, Annex M, and SHDSL.
The GDS-DSL access network design relies on a bidirectional, highly resilient, fiber optics ring running through the COs of Al-Nahr, Hamra, and Achrafieh (the COs housing GDS DSL core routers) used as aggregation points for other COs via MoT’s fiber transport infrastructure. This setup is completely independent from the wireless service network.
All locations served access the network using ADSL/SHDSL technologies over the copper telephone infrastructure to reach GDS-DSLAMs (Digital Subscriber Line Access Multiplexers) located in the COs, which serve as access nodes. Using MoT’s fiber transport infrastructure, these DSLAMs are then connected to the main DSL core routers where layer 3 over MPLS protocol is implemented.
Third Generation (3G) represents the 3rd generation of mobile telecommunications technology, which allows users to connect from home, work, or when on the move. The widely available service offers speeds of up to 7.2Mbps (speed is dependent on signal strength, user and device location, device type, load on the base station, and type of application being used).
At the end of Q3 2012, GDS, along with its affiliated ISPs (IDM and Cyberia), successfully completed the pilot test on the 3G mobile solution and immediately started providing the service to IDM and Cyberia residential users.
GDS also provides its WAN customers with VPN over 3G layer 3 routed service in remote sites or as additional protection to the wireless or wired DSL connections, or as a secure remote access to customers’ WAN network.
Ethernet and 3G interfaces can be used to provide the service.
