Title:
パケット通信装置及びパケットスイッチ
Document Type and Number:
Japanese Patent JP4023281
Kind Code:
B2
Abstract:
A reliable packet communication device capable of flexibly adding new functions. A packet communication device is composed of multiple interface elements (IFEs), switching elements (SWE) connecting these IFEs, and a routing manager element (RME) and may also if necessary comprise special functional packet processors (xFPs) capable of different special functions. The interface element and special functional packet processor are connected by a logical bus. For the purpose of connecting the interface elements and special functional packet processors through the switching element when the logical bus has a failure, the logical bus data format is made identical to the data format for passing data through the switch element and a selection circuit is installed in the interface element for selectively sending and receiving data to/from either the logical bus or the switching element.
