Metro Ethernet (ME)

A metropolitan-area Ethernet, Ethernet MAN, or metro Ethernet network is a metropolitan area network (MAN) that is based on Ethernet standards using fiber optical as the main network to support huge data transmission in Bangladesh Metropolitan. BD Link Offers high-speed data, Internet, voice over IP (VoIP), video and other applications with flexible speeds of up to 10 Gbps. With Metro Ethernet you may be able to take advantage of your current router interface, avoiding the need to purchase additional equipment. Metro Ethernet is a cost-effective solution because it requires fewer physical interfaces, servers and routers to build your network than some other technologies, and it my allow you to use existing equipment you already have in place.

Ethernet over Synchronous Digital Hierarchy (EoSDH)

EoSDH’ is delivered using BD Link’s synchronous digital hierarchy network ( SDH), which provides dedicated bandwidth for uncompromising quality. Ethernet over Synchronous Digital Hierarchy (EoSDH) is an exceedingly high speed circuit using Ethernet technology based on SDH network which is developed from the existing technology by combining the distinctive characteristic of each technology i.e. the outstanding feature of Ethernet is its ease of usage and prevalence whilst SDH is recognized for its reliability; hence, this combined technology is suitable for users that need reliable data transmission via Ethernet connection. Customers may wish to enhance their service and traffic management capabilities by implementing their own network overlay on our Ethernet services.

Transparent VLAN carriage and Jumbo Frames are supported on BD Link’s ‘EoSDH Network. Presently, the company offers EoSDH service from 2Mbps. to 10 Gbps. by combining SDH’s distinctive characteristic of reliability in service with the widespread usage of Ethernet interface whereby this technology is suitable for users that require reliable data transmission based on Ethernet connect i.e. multinationals etc. Bandwidths are available from 2Mbit/s to 10Gbit/s

Synchronous Digital Hierarchy (SDH)

SDH (Synchronous Digital Hierarchy) is a standard technology for synchronous data transmission on optical media. It is the international equivalent of Synchronous Optical Network. Both technologies provide faster and less expensive network interconnection than traditional PDH (Plesiochronous Digital Hierarchy) equipment. There is reliable control system with uncomplicated and reliable capability to transmit long distance data. There is also route protection system with the ability to switch transmission cable in the event of damage incurred to regular cable to ensure continuity and reliability of data transmission. Presently, the company offers SDH service from 34Mbps. to 10 Gbps. via fiber optic cable to diverse customer

Global MPLS

Multiprotocol Label Switching (MPLS) is a protocol for speeding up and shaping network traffic flows. MPLS allows most packets to be forwarded at Layer 2 (the switching level) rather than having to be passed up to Layer 3 (the routing level). Each packet gets labeled on entry into the service provider's network by the ingress router. All the subsequent routing switches perform packet forwarding based only on those labels—they never look as far as the IP header. Finally, the egress router removes the label(s) and forwards the original IP packet toward its final destination.
