Abstract:
A frame relay communications network (12) consists of a number of interconnected nodes (20). The network nodes (20) include segmentation and reassembly means for fragmenting variable length frames (200) of user data into packets of a predefined length. A preferred embodiment uses ATM AAL5 segmentation and reassembly to construct cells. Header and trailer information is added to each of the cells for transport across the frame relay network.
Abstract:
A method and apparatus for managing a network access device (400) is provided. Embedded within the access device are three distinct software layers. The first layer (422) is a combined text-interface generator and Hypertext Transport Protocol client. The second layer (424) is a combined Hypertext Transport Protocol server and Simple Network Management Protocol manager. The third layer (426) is a Simple Network Management Protocol agent that has direct access to the configuration data of the access device (400). A user can manage the device through the embedded text-interface generator (410), by using an external HTTP client to communicate with the embedded HTTP server (414), or by using an external SNMP manager to communicate with the embedded SNMP agent (418). Techniques are disclosed for embedding SNMP information in messages passed between HTTP clients and servers.
