Read MoreWhat is Gigabit Ethernet?
Gigabit Ethernet is a high-speed variant of Ethernet technology that transmits data at 1 Gbps (1, 000 Mbps) in local area networks (LANs). It serves as a backbone for enterprise networks, providing significantly faster data transmission than earlier Ethernet standards. Gigabit Ethernet extends the proven 802.3 Ethernet family, which includes 10 Mbps and 100 Mbps variants. It delivers ten times the bandwidth of Fast Ethernet while maintaining full backward compatibility with existing Ethernet infrastructure and devices. How Gigabit Ethernet Works Gigabit Ethernet uses different physical media depending on the transmission distance. For long-distance connections, it typically employs ...
Read MoreWhat is NGN?
NGN stands for Next Generation Network. It defines the evolution and migration of traditional circuit-switched and mobile network frameworks from distinct proprietary networks to converged IP-based networks. NGN represents an interworking environment of heterogeneous networks including wired and wireless access networks, PSTN, satellites, and transmission systems. Next-generation networks are designed to carry all types of services and data such as voice calls, audio data, and multimedia content including videos. All communication data is encapsulated in packet format, enabling efficient transmission over IP infrastructure. An NGN is fundamentally based on Internet protocols such as MPLS and IP. It uses ...
