Cisco CRS-1 Series XML API and Cisco CRS-1 Series Router
System Features
Using the Cisco CRS-1 Series XML API, an external client application can send XML encoded
management requests to an XML agent running on the Cisco CRS-1 Series router. The initial release of
the API supports CORBA as the transport mechanism. Using CORBA, the client application sends XML
encoded requests to the router via remote operation calls. The remote operation interface is implemented
on the router by the CORBA specific XML agent. Future releases of the Cisco CRS-1 Series XML API
will support other transport mechanisms, which may include terminal based protocols such as Telnet and
Secure Shell (SSH). The Cisco CRS-1 Series XML API interface described in this document will apply
equally to all supported transports.
A client request sent to the Cisco CRS-1 Series router must specify the different types of operations to
be carried out. The following three general types of management operations are supported through XML:
•
•
•
When a client request is received by an XML agent on the router, the request is routed to the appropriate
XML operation provider in the internal Cisco CRS-1 Series XML API library for processing. After all
the requested operations are processed, the XML agent receives the result and then sends the XML
encoded response stream on to the client.
