rfc2674.txt IEEE 802.5." GROUP pBridgePriorityGroup DESCRIPTION "This group is mandatory only for devices supporting the priority forwarding operations defined by IEEE 802.1D." GROUP pBridgeAccessPriorityGroup DESCRIPTION "This group is optional and is relevant only for devices supporting the priority forwarding operations defined by IEEE 802.1D and which have interface media types that support native Access Priority e.g. The original IEEE 802.1D is augmented by IEEE 802.1Q-1998 [802.1Q] to provide support for 'virtual bridged LANs' where a single bridged physical LAN network may be used to support multiple logical bridged LANs, each of which offers a service approximately the same as that defined by IEEE 802.1D. The transparent method of bridging is defined by IEEE 802.1D-1998 [802.1D] which is an update to the original IEEE 802.1D specification [802.1D-ORIG]. www.ietf.org /rfc/rfc2674.txt   (8005 words)

79830.001228&ELEMENT_SET=DECL In the embodiment it is specified that the switched domain 5 operates according to the standards IEEE 802.1D, IEEE 802.1Q and IEEE 802.1p, which is a substandard to IEEE 802.1D. The standard IEEE 802.1Q, which has been adapted as industrial standard for VLAN, is based on standard LAN switches according to IEEE 802.2 standards. If the link board in the user device supports the standards 802.1Q and 802.1p, this board can directly label the CoS bits 22 in the packets which is to be transmitted from the user device via the switched domain 5 to a receiver. www.wipo.int /cgi-pct/guest/getbykey5?KEY=00/79830.001228&ELEMENT_SET=DECL   (5485 words)

IEEE 802.1Q - Wikipedia, the free encyclopedia IEEE 802.1Q also defines the meaning of a virtual LAN or VLAN with respect to the specific conceptual model underpinning bridging at the MAC layer and to the IEEE 802.1D spanning tree protocol. IEEE 802.1Q is also the name of the standard issued by this process, and in common usage the name of the encapsulation protocol used to implement this mechanism over Ethernet networks. IEEE 802.1Q was a project in the IEEE 802 standards process to develop a mechanism to allow multiple bridged networks to transparently share the same physical network link without leakage of information between networks (i.e. en.wikipedia.org /wiki/IEEE_802.1Q   (469 words)

Switch 4007 Implementation Guide IEEE 802.1D, which now incorporates 802.1p, uses this same frame format but it takes advantage of an additional 3 bits to specify the priority levels used for Class of Service differentiation. Tagged IEEE 802.1Q data frames that are received on the system are assigned to the VLAN that corresponds to both the VID contained in the tag and the protocol type. IEEE 802.1Q defines the bridging rules for VLANs (ingress and egress rules, as described in detail in "Rules of VLAN Operation" later in this chapter). support.3com.com /infodeli/tools/switches/4000/4007/13673/9i3vla3a.htm   (1175 words)

Intel® Express 460T Standalone Switch - Virtual Local Area Networks (VLANs) GARP (Generic Attribute Registration Protocol) is defined by the IEEE 802.1D (1998 Edition) specification and is the mechanism used by switches and end nodes to propagate VLAN configurations across the network domain. The third type of VLAN supported by the Express 460T switch is based on the IEEE 802.1Q specification.

Cisco - Understanding Rapid Spanning Tree Protocol (802.1w) Rapid Spanning Tree Protocol (RSTP; IEEE 802.1w) can be seen as an evolution of the 802.1d standard more than a revolution. RSTP (IEEE 802.1w) natively includes most of Cisco's proprietary enhancements to the 802.1d spanning tree such as BackboneFast, UplinkFast, and PortFast. As a result, RSTP calculates the final topology for the spanning tree using exactly the same criteria as 802.1d. www.cisco.com /warp/public/473/146.html   (1446 words)

RFC 2816 (rfc2816) - A Framework for Integrated Services Over Shared and S IEEE 802.1D [3] defines a consistent way for carrying the value of the user_priority over a bridged network consisting of Ethernet, Token Ring, Demand Priority, FDDI or other MAC layer media using an extended frame format. Token Ring/IEEE 802.5 The Token Ring standard [6] provides a priority mechanism that can be used to control both the queuing of packets for transmission and the access of packets to the shared media. In the remainder of this document, for the discussion of QoS mechanisms, FDDI is treated as a 100 Mbps Token Ring technology using a service interface compatible with IEEE 802 networks. www.faqs.org /rfcs/rfc2816.html   (13155 words)
