be an intelligent peripheral installed within a server or may be a network
processor (NP) coupled to a server. The method and system forward
connections by determining whether or not a particular connection should be
handled by another node. In response to determining that the particular
connection should be handled by another node, the network controller
forwards the connection by performing header mangling within the network
controller. The packet destination addresses are modified to reflect the
address of the other node and the source address is modified to reflect a node
of the network controller. Responses received from the other node are
modified to indicate a response from the original destination node, thus
making the connection forwarding transparent to external switches and other
devices (Specification 4).
Representative claim 1 is illustrative:
1. A method for forwarding connections at a server, comprising:
receiving a packet at a network controller of said server, wherein said
packet is destined for an original destination node of said server and was
provided by an originating source;
within said network controller, selecting an alternate destination node
for said packet;
modifying a destination address and an origin address of said packet
within said network controller to produce a modified packet containing a
destination address of said alternate destination node and an origin address
of a response node of said network controller; and
transmitting said modified packet from said network controller to said
alternate destination node.
