Abstract: Techniques of operating a server computer running an application for clients operating in multiple network namespaces involve multiplexing communications streams from clients hosted in different network namespaces into a single communication stream to present the requests to an application as if they originated from a single network namespace. Along these lines, a server computer commences operation by initiating a network namespace driver for each network namespaces and a multiplexing driver to multiplex network namespace communication streams received from the network namespace drivers. When the multiplexing driver receives an application access request from a network namespace driver within a network namespace communication stream, the multiplexing driver provides the request and a network namespace identifier identifying the network namespace driver to a stream head within a multiplexed communication stream that includes requests from other network namespace drivers.

Abstract: Techniques for routing network traffic in a storage processor involve providing per-IP routing tables for each IP address of a virtual server and a per-server routing table. These per-IP and per-server routing tables specify its own interface(s) with external network(s). The storage processor assigns each outbound protocol data unit (PDU), generated by a particular virtual server, to either a per-IP routing table or a per-server routing table provided for that virtual server. The assignment of the routing table is based on source IP address or a connection mark associated with an outbound PDU. The per-IP or per-server routing table(s) identifies an interface through which the packet is routed to the destination IP address.
