Prior to the introduction of the 802. 1Q standard, several proprietary protocols existed, such as Cisco's ISL ( Inter-Switch Link ) and 3Com's VLT ( Virtual LAN Trunk ).

Other trunking protocols have been used but have become obsolete, including Inter-Switch Link ( ISL ), IEEE 802. 10 ( originally a security protocol but a subset was introduced for trunking ), and ATM LAN Emulation ( LANE ).

Cisco also has a proprietary trunking protocol called Inter-Switch Link which encapsulates the Ethernet frame with its own container, which labels the frame as belonging to a specific VLAN.

The Cisco Inter-Switch Link ( ISL ) protocol for supporting VLANs on Ethernet and similar LAN technologies was based on IEEE 802. 10 ; in this application 802. 10 has largely been replaced by IEEE 802. 1Q.

Inter-Switch Link can stand for:

* Cisco Inter-Switch Link ( ISL ) is a Cisco proprietary protocol that maintains VLAN information as traffic flows between switches and routers.

Cisco Inter-Switch Link ( ISL ) is a Cisco Systems proprietary protocol that maintains VLAN information in Ethernet frames as traffic flows between switches and routers, or switches and switches.

Another related Cisco protocol, Dynamic Inter-Switch Link Protocol ( DISL ) simplifies the creation of an ISL trunk from two interconnected Fast Ethernet devices.

These devices synchronize state across an Inter-Switch Trunk ( IST ) such that they appear to the connecting ( access ) device to be a single device ( switch block ) and prevent any packet duplication.

Link Grammar is both a theory of syntax and an open source parser which is now developed by the AbiWord project.

Well-known communications protocols are Ethernet, a hardware and Link Layer standard that is ubiquitous in local area networks, and the Internet Protocol Suite, which defines a set of protocols for internetworking, i. e. for data communication between multiple networks, as well as host-to-host data transfer, and application-specific data transmission formats.

The agreement with the Kyoto Prefecture, concluded in 1994, is officially styled as a ' Friendship Link ', reflecting its status as the only region to be twinned with Edinburgh.

A new high-speed service, namely the Guangzhou-Shenzhen-Hong Kong Express Rail Link, is being built.

It does not discuss hardware-specific low-level interfaces, and assumes availability of a Link Layer interface to the local network link to which the host is connected.

It defines Logical Link Control ( LLC ), which is the upper portion of the data link layer of the OSI Model.

IPv4 is a connectionless protocol for use on packet-switched Link Layer networks ( e. g., Ethernet ).

Kajang is well connected with many major highway and expressway like Kajang Dispersal Link Expressway as a ring road of Kajang, Cheras-Kajang Expressway ( CKE, ), North-South Expressway ( NSE ) () with Kajang exit and Kajang-Seremban Expressway ( LEKAS, ) at the south of Kajang near Semenyih.

PPP is commonly used as a data link layer protocol for connection over synchronous and asynchronous circuits, where it has largely superseded the older Serial Line Internet Protocol ( SLIP ) and telephone company mandated standards ( such as Link Access Protocol, Balanced ( LAPB ) in the X. 25 protocol suite ).

A link-state routing algorithm optimised for mobile ad-hoc networks is the Optimised Link State Routing Protocol ( OLSR ).

Other DS9 episodes to make reference to the animated series include " Broken Link ", where Elim Garak mentions Edosian orchids ( Arex is an Edosian ) and " Tears of the Prophets " where a Miranda class starship is called the USS ShirKahr ( sic ) after Shikahr, the city from " Yesteryear ".

Link is often given the task of rescuing Princess Zelda in the most common setting of the series, Hyrule, from Ganon ( also known as Ganondorf ), a Gerudo chief who is the primary antagonist of the series.

The protagonist in each game is usually not the same incarnation of Link, but a few exceptions do exist.

The producer of Skyward Sword has said that, as Link is entirely mute, having the other characters speak while Link remains silent would be off-putting.

However, because the Triforce was not divine </ ref > Each Link is described on the series ' official website as humble, hardworking and brave, and therefore appropriate to bear the Triforce of Courage.

Link is left-handed, with two exceptions.

In the Wii version of Twilight Princess, Link is right-handed due to the " mirroring " used to accommodate the right-handed control scheme, which flips the entire game world's layout from that of its Nintendo GameCube counterpart.

Link is also right-handed in the title Skyward Sword.

( Note that the term ' trunk ' is also used for what Cisco calls " channels ": Link Aggregation or Port Trunking ).
