Abstract: A symmetric flow response path from an Autonomous System (AS) can be forced by using a same edge gateway for ingress and egress of communications with an Internet source. An asymmetric flow response path from an AS can be used by using different edge gateways for ingress and egress of communications with an Internet source. An anycast IP address can be used for selecting egress edge gateways of an AS. Packets in an AS can be redirected to selected egress edge gateways of the AS.

Abstract: A redirector within an Autonomous System (AS) is configured to access a set of Routing and Forwarding (RF) tables associated with a respective set of tenants. A current packet, addressed to a private IP address of a private tenant network outside the AS, is received by the redirector. The redirector executes a look up of the private IP address in a RF table, from the set of RF tables, that corresponds to the tenant associated with the packet. The redirector selects an egress interface of a egress gateway of the AS based on the look up. The redirector encapsulates the current packet and an identifier of the egress interface within an outer packet and transmits the outer packet to the egress gateway. The egress gateway transmits the packet toward the private IP address of the private tenant network using the egress gateway selected by the redirector.

Abstract: A method and system for pointing a Internet user requesting access to content on a particular web site to one of a plurality of content servers associated with that web site based on one or more cost measurements associated with serving said content. The identification of the web site is mapped to the content servers associated with that web site. The user's IP address is then mapped to a particular content server based on a cost function and the IP address of the selected content server is provided to the user.
