[. . . ] the eight priority tags , specified in IEEE 802. 1p are mapped to the Switch's priority tags as follows: • • • • • • • Priority 0 is assigned to the Switch's Q1 queue. The Switch uses strict priority for Scheduling. Strict priority-based scheduling, any packets residing in the higher priority queues are transmitted first. 2 D-Link DGS-105/108 Gigabit Ethernet Switch Switching Technology Another key development pushing the limits of Ethernet technology is in the field of switching technology. A switch bridges Ethernet packets at the MAC address level of the Ethernet protocol transmitting among connected Ethernet or fast Ethernet LAN segments. Switching is a cost-effective way of increasing the total network capacity available to users on a local area network. A switch increases capacity and decreases network loading by making it possible for a local area network to be divided into different segments that do not compete with each other for network transmission capacity, decreasing the load on each segment. The switch acts as a high-speed selective bridge between the individual segments. Traffic that needs to go from one segment to another (from one port to another) is automatically forwarded by the switch, without interfering with any other segments (ports). This allows the total network capacity to be multiplied, while still maintaining the same network cabling and adapter cards. For Fast Ethernet or Gigabit Ethernet networks, a Switch is an effective way of eliminating problems of chaining hubs beyond the “two-repeater limit. € A Switch can be used to split parts of the network into different collision domains, for example, making it possible to expand your Fast Ethernet network beyond the 205-meter network diameter limit for 100BASE-TX networks. Switches supporting both traditional 10Mbps Ethernet and 100Mbps Fast Ethernet are also ideal for bridging between existing 10Mbps networks and new 100Mbps networks. Switching LAN technology is a marked improvement over the previous generation of network bridges, which were characterized by higher latencies. Routers have also been used to segment local area networks, but the cost of a router and the setup and maintenance required make routers relatively impractical. Today’s Switches are an ideal solution to most kinds of local area network congestion problems. switch Description The DGS-105/108 Switch is equipped with five ports providing dedicated 10 , 100 , or 1000 Mbps bandwidth. These ports can be used for connecting PCs, printers, servers, routers, Switches, hubs, and other network devices. The five multi-speed ports use standard twisted pair cabling and are ideal for segmenting networks into small, connected subnets. Each port can support up to 2000 Mbps of throughput in full-duplex mode. This stand-alone Switch enables the network to use some of the most demanding multimedia and imaging applications concurrently with other user applications without creating bottlenecks. [. . . ] the rules dictate format , timing , sequencing , and error control. Resilient link – A pair of ports that can be configured so that one will take over data transmission should the other fail. Subset of SNMP MIB II, which allows monitoring and management capabilities by addressing up to ten different groups of information. rPS – Redundant Power System. [. . . ]
