OSPF. Hozirda korporativ tarmoqlarda sozlash nisbatan universal va qulay bo'lgan dinamik marshrutizatsiya protokoli birinchi qisqa yo‘lni tanlash ochiq protokoli Open Short-est Path First Protocol — OSPF) hisoblanadi. Dastlab protokol murakab topologiyali katta tarmoqlar (65536 tagacha marshrutizator) da ishlashga mo‘ljallangan. U aloqa kanali holati algoritmiga asoslangan va tarmoq holati o‘zgarishiga yuqori chidamlikka ega.

BGP (ing. Border Gateway Protocol, chegaraviy shlyuz protokoli) Intemetdagi asosiy dinamik marshrutlash protokoli hisoblanadi.
BGP protokoli boshqa dinamik marshrutlash protokollaridan farqli o‘laroq, marshrut ma’lumotlarini alohida marshrutlagichlar o‘rtasida emas, balki butun avtonom tizimlar o‘rtasida almashish uchun mo‘ljallangan va shu sababli, tarmoqdagi marshrutlar haqida ma’lumotlardan tashqari, avtonom tizimlarga yo‘nalishlar to‘g‘risida ham ma’lumot olib boradi.
