This is about the network design strategies for riding in auto cargo space, see Trunking auto , and for the UK term for electrical wireways, see Electrical conduit Trunking . In modern communication s, trunking is a concept by which a communications system can provide network access to many clients by sharing a set of lines or frequencies instead of providing them individually. This is analogous to the structure of a tree with one trunk and many branches. Examples of this include telephone systems and the VHF radios commonly used by police agencies.

The Dynamic Trunking Protocol DTP is a proprietary networking protocol developed by Cisco Systems for the purpose of negotiating trunking on a link between two Virtual LAN VLAN aware Network switch switches , and for negotiating the type of trunking Encapsulation networking encapsulation to be used. It works on the Data Link Layer Layer 2 of the OSI model . VLAN trunks formed using DTP may utilize either IEEE 802.1Q or Cisco Inter Switch Link Cisco ISL trunking protocols. DTP should not be confused with VLAN Trunking Protocol VTP , as they serve different purposes. VTP communicates VLAN existence information between switches. DTP aids with trunk port establishment. Neither protocol transmits the data Frame telecommunications frames that trunks carry. Switch port modes The following switch port mode settings exist auto &mdash causes the port to passively be willing to convert to trunking. The port will not trunk unless the neighbor is set to on or desirable . This is the default mode. Note that auto auto both ends default links will not become trunks. on &mdash forces the link into permanent trunking, even if the neighbor doesn t agree. off &mdash forces the link to permanently not trunk, even if the neighbor doesn t agree. desirable &mdash causes the port to actively attempt to become a trunk, subject to neighbor agreement neighbor set to on , desirable , or auto . nonegotiate &mdash forces the port to permanently trunk but not send DTP frames. For use when the DTP frames confuse the neighboring non Cisco 802.1Q switch. The neighboring switch must be set to trunking manually.

Cisco s VLAN Trunk Protocol reduces administration in a switched network. When a new VLAN is configured on one VTP server, the VLAN is distributed through all switches in the domain. This reduces the need to configure the same VLAN everywhere. To do this, VTP carries VLAN information to all the switches in a VTP domain. VTP advertisements can be sent over Cisco Inter Switch Link ISL , 802.1q , IEEE 802.10 and LANE trunks.

Distributed Split Multi Link Trunking DSMLT or Distributed SMLT is a computer networking technology designed by Avaya to enhance the Split Multi Link Trunking SMLT protocol. DSMLT allows the ports in a trunk to span multiple units of a stack of switches or to span multiple cards in a chassis, preventing network outages when one switch in a stack fails or one card in a chassis fails. Fault tolerance is a very important aspect of Distributed Split Multi Link Trunking DSMLT technology. Should any one switch, port, or more than one link fail, the DSMLT technology will automatically redistribute traffic across the remaining links. Automatic redistribution is accomplished in less than half a second typically less than 100 milliseconds ref cite web url http www.tolly.com ts 2007 Nortel ERSswitches Tolly207171NortelERSwitchSMLT.pdf title Evaluation of Resilient Routing Switches for Real Time Multimedia Traffic with Microsoft Live Communications Server 2005 and Nortel MCS 5100 publisher The Tolly Group ref so no outage is noticed by end users.

The GoTA system was developed by ZTE , a Chinese manufacturer. The GoTA system can be used for both private and public trunking network applications. GoTa is capable of providing a variety of trunking services One to one private calls and one to many group calls The ability to set the user s priority The ability to perform forced insertion forced release based on the user s priority The ability to provide special services such as system paging, group paging, sub group paging, and dedicated Push to talk Push To Talk services as required The ability to classify the groups into permanent and temporary groups, in which the group members can be managed by the user. In addition to trunking service, GoTa can provide value added services such as short messages, location based services and other data services. The original GoTa standard was developed for the CDMA frequency bands 800 MHz band. GoTa is adapted to work in the 450 MHz band as well.
