In network routing, the control plane is the part of the router architecture that is concerned with drawing the network topology, or the information in a (possibly augmented) routing table that defines what to do with incoming packets. Control plane functions, such as participating in routing protocols, run in the architectural control element. In most cases, the routing table contains a list of destination addresses and the outgoing interface(s) associated with them. Control plane logic also can define certain packets to be discarded, as well as preferential treatment of certain packets for which a high quality of service is defined by such mechanisms as differentiated services.
Software control plane for switches and routers
ActiveUS20080219268A1Bridging the gapImprove convenienceError preventionTransmission systemsQuality of serviceAbstraction layer
A Provider Network Controller (PNC) addresses the challenges in building services across Next Generation Network (NGN) architectures and creates an abstraction layer as a bridge, or glue, between the network transport and applications running over it. The PNC is a multi-layer, multi-vendor dynamic control plane that implements service activation and Layer 0-2 management tools for multiple transport technologies including Carrier Ethernet, Provider Backbone Transport (PBT), Multi-protocol Label Switching (MPLS), Transport MPLS (T-MPLS), optical and integrated networking platforms. Decoupling transport controls and services from the network equipment simplifies service creation and provides options for carriers to choose best-in-class equipment that leverages the PNC to enable rapid creation and management of transports and services. The PNC provides Service-Oriented Architecture (SOA) interfaces to abstract transport objects expressly designed to support both wholesale and retail services, and supports service offerings with varied bandwidth and Quality of Service (QoS) requirements, thus achieving enterprise Ethernet economics.

Softrouter separate control network
ActiveUS20060092976A1Time-division multiplexData switching by path configurationTraffic capacityExtensibility
An embodiment of the exemplary SoftRouter architecture includes two physically separate networks, a control plane network and a data plane network. The data plane network is one physical network for the data traffic, while the control plane network is another physical network for the control traffic. The topology of the data plane network is made up of interconnected forwarding elements (FEs). The topology of the control plane network is made up interconnected control elements (CEs). This physical independence of the control plane network from the data plane network provides for a secure mechanism to communicate among the CEs in the control plane network. In addition, this physical independence provides improved reliability and improved scalability, when compared to the traditional router architecture, where control plane message are in-band with the data plane.

Softrouter protocol disaggregation
ActiveUS20060092940A1Data switching by path configurationSecuring communicationFailoverRate of convergence
A SoftRouter architecture deconstructs routers by separating the control entities of a router from its forwarding components, enabling dynamic binding between them. In the SoftRouter architecture, control plane functions are aggregated and implemented on a few smart servers which control forwarding elements that are multiple network hops away. A dynamic binding protocol performs network-wide control plane failovers. Network stability is improved by aggregating and remotely hosting routing protocols, such as OSPF and BGP. This results in faster convergence, lower protocol messages processed, and fewer route changes following a failure. The SoftRouter architecture includes a few smart control entities that manage a large number of forwarding elements to provide greater support for network-wide control. In the SoftRouter architecture, routing protocols operate remotely at a control element and control one or more forwarding elements by downloading the forwarding tables, etc. into the forwarding elements. Intra-domain routing and inter-domain routing are also included.

Hardware abstraction layer
ActiveUS20060193266A1Eliminate needData switching by path configurationInformation repositoryComputer hardware
Switching and routing functions may be provided in a data plane of a network switch by having all functions and algorithms needed to handle all related interface, logical and physical, under one interface manager to keep track of bindings between virtual interfaces and logical interfaces, as well as maintain the statuses of ports that belong to the virtual interface and the actual logical ports. When the actual interface goes down, the virtual interface may go down along with it. The bindings may also include definitions. All of these bindings may be located in a single routing information base (RIB) database, eliminating the need for multiple bindings to be kept in various places. Furthermore, a hardware abstraction layer in the control plane can also then be mirrored in the data plane, eliminating the need for the customer to create a layer performing the same tasks.

Techniques for load balancing over a cluster of subscriber-aware application servers
InactiveUS20070165622A1Digital computer detailsNetwork connectionsApplication serverDistributed computing
Techniques for distributing control plane traffic, from an end node in a packet switched network to a cluster of service gateway nodes that host subscriber-aware application servers, include receiving a control plane message for supporting data plane traffic from a particular subscriber. A particular service gateway node is determined among the cluster of service gateway nodes based on policy-based routing (PBR) for the data plane traffic from the particular subscriber. A message based on the control plane message is sent to a control plane process on the particular service gateway node. Thereby, data plane traffic and control plane traffic from the same subscriber are directed to the same gateway node, or otherwise related gateway nodes, of the cluster of service gateway nodes. This approach allows currently-available, hardware-accelerated PBR to be used with clusters of subscriber-aware service gateways that must also monitor control plane traffic from the same subscriber.

Live Router Migration
InactiveUS20110032830A1Easily and quickly migrateError preventionFrequency-division multiplex detailsData trafficReal time routing
Live router migration is implemented by separating the logical features of a virtual router from its physical features. Tunnels are established between a source (physical) router and a destination (physical) router, allowing the control plane of the virtual router being migrated to send and receive messages from the destination router. The control plane information is then transferred to the destination router, which functions to clone the data plane at the destination router. Outgoing links from the destination router are then be established. The double appearance of the data plane at both the source and destination routers allows for the data plane information to be transferred asynchronously over to the destination router. Once all of the data plane information has been transferred, incoming data traffic links at the destination router can be established and the tunnels between the routers taken down.
