      As new technologies emerge, more and more premises network users will demand a reliable and high-speed wide area network connection to carry data, voice, video and multimedia content.

      D-Link helps service providers to meet these demands by providing a complete range of premises network connectivity devices, including cable modem, xDSL Integrated Access Device wireless routers, Gigabit Passive Optical Networks Optical Network Terminal and Ethernet switches for Fiber to the Business / Ethernet to the Home.

      IPv6 support makes these devices adaptable to the emerging IPv6 network environment. These devices are designed by D-Link to ensure excellent performance for each network technology used by service providers. This helps them deliver their network services and, at the same time, provides flexibility for application and implementation by end users.

      Moving to the upper layer after the premises network is the access network. D-Link offers layer-2/3 Ethernet switches as a reliable termination point for each of the services delivered by the service provider for an access network. D-Link solutions for access networks include features, such as

      • Network segmentation – VLANNetwork segmentation allows the service provider to group customers into different network segments based on their service level for easier network management and service delivery.
      • User Authentication and Network SecurityAt the access network, D-Link provides user authentication and network security features to eliminate unauthorized users and malicious traffic before it reaches the core network. These features include 802.1X authentication, Web-based Access Control, RADIUS and TACACS support, Safeguard Engine, ACL, IGMP Authentication and many more.

      Traffic that successfully passed the security filter and authentication process in the access network will be gathered into the service provider’s aggregation and core networks. In this network layer, the service provider will need powerful devices to process the heavy network traffic load before forwarding traffic to its next destination. D-Link solutions also provide the following essential functions:

      Routing
      D-Link aggregation and core network solutions support static route, RIP I/II, OSPF, RIPng for IPv6 implementation, DV MRP and PIM Sparse/Dense mode for multicast implementation.

      High availability
      D-Link solutions assures continuity of aggregation and core networks with redundant power supply, stacking configuration and Virtual Router Redundancy Protocol.

      Bandwidth management
      With D-Link aggregation network solutions, service providers are able to manage their bandwidth allocation for each customer to meet any service level agreements.
