Compatible methods and systems for multiple spanning tree protocols
First Claim
1. A compatible method for multiple spanning tree protocols, comprising:
- providing a verification module between a standard multiple spanning tree (MST) module and a LLC layer and Ethernet driver module for executing a reception verification procedure and a transmission verification procedure, wherein the verification module, the standard MST module, and the LLC layer and Ethernet driver module are established in a switch;
receiving a bridge protocol data unit (BPDU); and
executing the reception verification procedure when the BPDU comes from the LLC layer and Ethernet driver module and executing the transmission verification procedure when the BPDU comes from the standard MST module.

Abstract
A compatible method for multiple spanning tree protocols. A verification module is provided between a standard multiple spanning tree (MST) module and a LLC layer and Ethernet driver module. The verification module executes a reception verification procedure and a transmission verification procedure. The verification module, the standard MST module, and the LLC layer and Ethernet driver module are established in a switch. A bridge protocol data unit (BPDU) is received by the verification module. If the BPDU comes from the LLC layer and Ethernet driver module, the verification procedure is executed for the received BPDU. If the BPDU comes from the standard MST module, the transmission verification procedure is executed for the BPDU.

10. A compatible system for multiple spanning tree protocols, comprising:
-
a verification module, established between a standard multiple spanning tree (MST) module and a LLC layer and Ethernet driver module for executing a reception verification procedure and a transmission verification procedure, wherein the verification module, the standard MST module, and the LLC layer and Ethernet driver module are established in a switch;
wherein the verification module further comprises;
a protocol identification module, identifying a class of a bridge protocol data unit (BPDU) and providing MST protocol records for a communication port;
a region verification module, verifying a region for a BPDU and providing identity information records of a communication port; and
a package conversion module, packaging BPDUs in various formats;
wherein when the verification module executes the reception verification procedure and the transmission verification procedure, required functions and parameters are provided by the protocol identification module, the region verification module, and the package conversion module. - View Dependent Claims (11, 12, 13, 14, 15, 16, 18, 19)
