First Claim
1. In a data communications system having at least one Legacy cloud coupled to at least one Beta cloud and further having at least one BOSS node and at least one border node, a method for ensuring compatibility comprising:
- determining when said BOSS node is idle;
determining whether the last packet transmitted by any border node was an Alpha format packet if said BOSS node is idle; and
unlocking said Legacy cloud if the last packet transmitted by said border node was nor an Alpha format packer.

4. In a data communications system having at least one Legacy cloud coupled to at least one Beta cloud and further having at least one border node receiving and transmitting packets, a method for ensuring compatibility comprising:
-
determining whether the last packet transmitted or received by the border node was an Alpha format packet; arbitrating for control of the bus if said last packet transmitted or received by the border node was not an Alpha format packet; determining whether said border node'"'"'s arbitration request was granted; repeating said last packet received if said arbitration request was not granted and returning back to the step of determining whether the last packet transmitted or received by the border node was an Alpha format packet; and unlocking the Legacy cloud if said arbitration request was granted. - View Dependent Claims (5, 6)
