A method for packet classification. In some embodiments, the method includes instantiating a first machine; allocating a first SC to the first machine, the first SC being configured to classify a packet based on information contained in a field of a header included in the packet; instantiating a second machine; allocating a second SC to the second machine, the second SC being configured to classify a packet based on information contained in a field of a header included in the packet; monitoring the first machine to detect if the first machine is in an overload state; and in response to detecting that the first machine is in an overload state, instantiating a third machine and allocating a third SC to the third machine, the third SC being configured to classify a packet based on information contained in a field of a header included in the packet.

Systems and methods for packet classification

Systems, methods, and computer program products for a software build and load process using a compilation and deployment service. A method for a software build and load process using a compilation and deployment service includes receiving, at the service, new software. The method further includes comparing, at the service, the received new software with data in a database, wherein the data comprises active software. The method further includes merging, at the service said new software and active software into one or more load modules based on the comparison. The method further includes deploying the one or more load modules to one or more target processing units.

Systems, methods, and computer program products for a software build and load process using a compilation and deployment service

A method implements a control plane of an evolved packet core (EPC) of a long term evolution (LTE) network in a cloud computing system. A cloud manager monitors resource utilization of each control plane module and the control plane traffic handled by each control plane module. The cloud manager detects a threshold level of resource utilization or traffic load for one of the plurality of control plane modules of the EPC. A new control plane module is initialized as a separate virtual machine by the cloud manager in response to detecting the threshold level. The new control plane module signals the plurality of network elements in the data plane to establish flow rules and actions to establish differential routing of flows in the data plane using the control protocol, wherein flow matches are encoded using an extensible match structure in which the flow match is encoded as a type-length-value (TLV).

Implementing EPC in a cloud computer with openflow data plane

A control plane device in a cloud computing system executes a plurality of virtual machines for implementing network function virtualization (NFV). The control plane device is operable to manage implementation of a general packet radio service (GPRS) tunnel protocol (GTP) in a packet core (PC) of a third generation (3G) network having a split architecture where a control plane of the PC of the 3G network is in the cloud computing system. The control plane communicates with a data plane of the PC through a control plane protocol. The data plane is implemented in a plurality of network devices of the 3G network. The control plane device and the plurality of virtual machines are operable to communicate with other control plane devices in the cloud computing system and with the plurality of network devices of the data plane.

Implementing a 3G packet core in a cloud computer with openflow data and control planes

A method for implementing a control plane of an evolved packet core (EPC) of a third generation partnership project (3GPP) long term evolution (LTE) network in a cloud computing system, including initializing the plurality of control plane modules of the EPC within the controller, each control plane module in the plurality of control plane modules initialized as a separate virtual machine by the cloud manager; monitoring resource utilization of each control plane module and the control plane traffic handled by each control plane module; detecting a threshold level of resource utilization or traffic load for one of the plurality of control plane modules of the EPC; and initializing a new control plane module as a separate virtual machine by the cloud manager in response to detecting the threshold level, the new control plane module to share the load of the one of the plurality of control plane modules.
