Web services across virtual routing and forwarding

Abstract: Disclosed is a method, system, and computer readable medium to provide an implementation to provide proxy style support for multiple virtual routing and forwarding (VRF) instances on a single network communication device. The proxy style support includes instantiating a plurality of pairs of namespaces and instances of a Unix service, each of the plurality of pairs representing a pair to support a single instance of a VRF. The network communication device may receive a network request associated with a network address mapped to a first VRF from a client device. The network request may be proxied from the pair of namespace/service supporting the first VRF to a backend single instance of a proxy server. Communication across independent namespaces may be supported by using a local communication mechanism (e.g., Unix sockets, Winsock) to provide support for the multiple VRFs concurrently.

Enabling access to dedicated resources in a virtual network using top of rack switches

Abstract: Systems and methods for enabling access to dedicated resources in a virtual network using top of rack switches are disclosed. A method includes a virtual filtering platform encapsulating at least one packet, received from a virtual machine, to generate at least one encapsulated packet comprising a virtual network identifier (VNI). The method further includes a TOR switch: (1) receiving the at least one encapsulated packet and decapsulating the at least one encapsulated packet to create at least one decapsulated packet, (2) using the VNI to identify a virtual routing and forwarding artifact to determine a virtual local area network interface associated with the dedicated hardware portion, and (3) transmitting the at least one decapsulated packet to the dedicated hardware portion based on at least one policy provided by a controller, where the at least one policy comprises information related to a customer of the service provider.

Method and system segregating application traffic in a wide area network

Abstract: In general, embodiments of the invention relate to a system and method for configuring and managing a network. More specifically, embodiments of the invention relate to segregating traffic in a network based on application domains. Further, embodiments of the invention provide a mechanism to efficiently implement traffic segregation in a network using application domain specific virtual routing and forwarding (VRF) tables.

System and method for network traffic processing based on federated services and user groups

Abstract: A system includes a first MODEM configured to generate a first data packet (including a first virtual routing and forwarding (VRF) instance identifier associated with a first service, a first user group, or both) based on a first radio-frequency (RF) signal and a second MODEM configured to generate a second data packet (including a second VRF instance identifier associated with a second service, a second user group, or both) based on a second RF signal. The system includes a network device configured to receive the first data packet, transmit a first packet (including a first header that includes a first indicator associated with a first VRF instance) to a first device via a network, receive the second data packet, and transmit a second packet (including a second header that includes a second indicator associated with a second VRF instance) to a second device via the network.

Extending virtual routing and forwarding

Abstract: In one embodiment of the disclosure, packets are routed according to a VRF (Virtual Routing and Forwarding) domain that is represented by a VRF identifier in a VRF-identifier (ID) field of packet headers. In one embodiment of the disclosure, a VRF identifier may be added to a VRF-ID field of a packet header so that the packet is routed according to a VRF domain that the packet belongs to.
