1. Förfarande för ruttväxling vid en förbindelse-orienterad, paketformad dataförbindelse, speciellt en 5 dataförbindelse i ett ATM-nät, i vilket förfarande trafik mellan tvä noder (A, B) i nätet överförs frän en första rutt (a - b) som skall tas ur bruk tili en andra, ny rutt (A-B), kännetecknat av att - noden (A) som inleder ruttväxlingen sänder ett 10 meddelande om ruttväxling tili noden (B) i den motsatta änden ooh börjar samtidigt motta trafik frän bäda rutter-na, - noden (B) i den motsatta änden börjar motta trafik frän de bäda rutterna efter att den mottagit meddelandet 15 om ruttväxlingen, - de bägge noderna flyttar sändnignen tili den nya rutten (A - B) sä att den motsatta änden mottar data frän endast en rutt ät gängen, ooh att - ruttväxlingen slutar för vardera noden däri att 20 den självmant slutar att avlyssna rutten som skall tas ur bruk.
2. Förfarande enligt patentkrav 1, kännetecknat av att noden (B) i den motsatta änden flyttar sin sändning tili den nya rutten före den inledan- 25 de noden (A), varvid växlingen sker som svar pä mottagan-det av meddelandet om ruttväxling, och att sändning av data tili den nya rutten (A - B) inleds vid behov först efter en buffringsperiod (T2) av given längd.
3. Förfarande enligt patentkrav 1 eller 2, k ä n -30 netecknat av att noden (A) som inleder ruttväxlingen utför en tidövervakning efter att den sänt medde- : landet om ruttväxlingen, varefter den avslutar sändningen tili rutten (a - b) som skall tas ur bruk.
4. Förfarande enligt patentkrav 1 eller 2, k ä n -35 netecknat av att noden (A) som inleder ruttväxlingen väntar efter sändningen av meddelandet om ruttväx- • 95637 12 ling att noden (B) i den motsatta änden kvitterar motta-gandet av meddelandet, varefter den (A) avslutar sändnin-gen till rutten (a - b) som skall tas ur bruk.
5. Förfarande enligt patentkrav 3, k ä n n e -5 tecknat av att noden (A) som inleder ruttväxlingen inleder sändningen till den nya rutten (A - B) vid behov först efter en buffringsperiod (T2) av given längd löpt ut efter att den avslutat sändningen till den ur bruk tagna rutten (a - b). II
