MPLS Fundamentals – ویدئو آموزشی

در پروتکل MPLS مي توان عمليات مسير يابي و تعيين پرش بعدي بسته ها را ترکيبي از دو عمليات مختلف تصور نمود. • عمليات اول ،‌ دسته بندي بسته هاي ورودي به يک سري کلاس هاي معادل هدايت به جلو Forwarding Equivalent Class (FEC) مي باشد. • عمليات دوم ، نگاشت هر FEC به يک پرش بعدي است. طبيعي است که تمامي بسته هايي که به يک FEC يکسان نگاشت مي يابند، از يک مسير واحد عبور ميکنند تا به مقصد برسند. در الگوريتم هاي مسير يابي متداول IP چنانچه دو بسته داراي پيشوند آدرس مقصد يکسان باشند، در اين صورت از يک مسير براي رسيدن به مقصد عبور مي نمايند.

Multiprotocol Label Switching (MPLS) is a type of data-carrying technique for high-performance telecommunications networks. MPLS directs data from one network node to the next based on short path labels rather than long network addresses, avoiding complex lookups in a routing table. The labels identify virtual links (paths) between distant nodes rather than endpoints. MPLS can encapsulate packets of various network protocols, hence its name “multiprotocol”. MPLS supports a range of access technologies, including T1/E1, ATM, Frame Relay, and DSL.
