Challenge

Stockholms Stadsnät provide Internet, IPTV and IP telephony services through their fibre network. Their main objective is to offer stable, fast and scaleable services to corporate and private customers in the greater Stockholm area. Stockholms Stadsnät’s main challenges include delivering the capacity purchased by each of their customers, usually 1/1 Gbps to corporations and households, and to maintain high service availability. In order to achieve this, they need a future-proof technical solution for tomorrow’s digital infrastructure, plus invested long-term partners that support their business.

Products

  • The DGS-3120 Series are used as access switches. They are very secure and can handle basic functions such as DHCP Snooping, QinQ, port isolation, VLAN, IPv6, IMPB etc. They support both copper and fibre connections with speeds up to 1 Gbps. The uplink speed is 10 Gbps.

  • The DGS-3130 Series are the next generation of access switches, which are now being installed in networks. They include the same functionality found in the DGS-3120 series, plus added capacity in order to meet future requirements. The uplink speed is 10 Gbps.

  • The DXS-3600 Series are used as 10 Gbps core switches and as connectors for all access switches. These switches have the capacity to handle high user workloads without compromising security. They are installed in a redundant ring for maximum availability.

  • The DXS-5000 Series are new high performing switches with a large number of 10 Gbps ports. These switches function as core switches and are successors to the DXS-3600 series.

  • The DGS-3420 Series are mainly used as distributions and access switches when the fibre network requires capacity increases. These switches have an uplink speed of 40 Gbps.

  • The DXS-1210 Series are new switches that can be used to connect end-users with a 10 Gbps connection. They are usedtogether with the DGS-3130 series for enduser functionality.
