    摘要: Apparatus, methods and computer programs enable carrying service insertion architecture data plane packets in IPv4 or IPv6 networks by packaging destination addresses using IPv6 mechanisms. For example, a data processing apparatus is configured for receiving, from a service broker, a service label and an Internet Protocol version 6 (IPv6) address of a first service node; receiving an IPv4 packet requesting a service associated with the first service node; creating an IPv6 packet comprising a service label in a Flow Label field of the IPv6 packet, the IPv6 address of the first service node in a destination address field of the IPv6 packet, and the IPv4 packet in a payload field of the IPv6 packet; forwarding the IPv6 packet to the first service node. Approaches allow service insertion architecture support for all-IPv6 traffic including tunneled and non-tunneled techniques for environments in which user applications place data in the flow label field.

    摘要: A system for selectively applying a service to a packet in a network. In a specific embodiment, the system includes a mechanism for encoding service information in a network-compatible packet header and providing encoded data in response thereto. In a more specific embodiment, the network-compatible header includes a Multi-Protocol Label Switching (MPLS) header, a Generic Route Encapsulation (GRE) header, and/or a Layer-2 Tunneling Protocol (L2TP) header.

    摘要: A generic service node that operates in a first state while waiting for instructions to adopt a specific service. Upon receiving the instructions, the generic service node operates in a second state where the node installs software received from a network to enable the generic service node to provide the specific service to the network. The generic service node is in communication with a control node or nodes such that the generic service node can be adapted to provide a particular service as requested by the control node(s).

    摘要: As described herein, explicit service ordering information may be associated with each of a plurality of logical services in a service path. A unique sequence number, for example, may be assigned, and associated with each service in the path. The sequence number may be assigned by a service broker in the control plane of a service insertion architecture that provides a platform-independent framework to insert services into a network. The sequence number may represent the relative ordering of the service with respect to the other services in the path. The sequence number, along with a traffic classification identifier, constitutes the shared context that is tagged to the packet injected into the chain which is used in the SIA data plane to virtualize and uniquely select series of services defined in the policy.
