Transparent bridging can also operate over devices with more than two ports. As an example, consider a bridge connected to three hosts, A, B, and C. The bridge has three ports. A is connected to bridge port 1, B is connected to bridge port 2, C is connected to bridge port 3. A sends a frame addressed to B to the bridge.
IEEE 802.1D is the Ethernet MAC bridges standard which includes bridging, Spanning Tree Protocol and others. It is standardized by the IEEE 802.1 working group. It includes details specific to linking many of the other 802 projects including the widely deployed 802.3 (Ethernet), 802.11 (Wireless LAN) and 802.16 (WiMax) standards.
Either mechanism carries either routed or bridged protocol data units, and DSL modems often include a setting for RFC 1483 bridging. This is distinct from other "bridge modes" commonly found in combined DSL modems and routers , which turn off the router portion of the DSL modem.
Network transparency, in its most general sense, refers to the ability of a protocol to transmit data over the network in a manner which is not observable (“transparent” as in invisible) to those using the applications that are using the protocol. In this way, users of a particular application may access remote resources in the same manner ...
TRILL (Transparent Interconnection of Lots of Links) is a networking protocol for optimizing bandwidth and resilience in Ethernet networks, [1] implemented by devices called TRILL switches. TRILL combines techniques from bridging and routing , and is the application of link-state routing to the VLAN -aware customer-bridging problem. [ 2 ]
In the process, he independently reinvented transparent bridging, the technique used in modern Ethernet switches. [7] However, using switches to connect multiple Ethernet networks in a fault-tolerant fashion requires redundant paths through that network, which in turn requires a spanning tree configuration.
Source-route transparent bridging, abbreviated SRT bridging, is a hybrid of source routing and transparent bridging, standardized in Section 9 of the IEEE 802.2 standard. It allows source routing and transparent bridging to coexist on the same bridged network by using source routing with hosts that support it and transparent bridging otherwise.
802.1ad specifies architecture and bridge protocols to provide separate instances of the medium access control (MAC) services to multiple independent users of a bridged local area network in a manner that does not require cooperation among the users and requires a minimum amount of cooperation between the users and the provider of the MAC service.
