The Evolved Packet Core portfolio includes SGSN/MME* and Mobile Packet Gateway – software upgrades of the existing SGSN and GGSN. PDF | SGSN and GGSN are the two core network elements of the general packet radio service which enables Ahmad Ali Habeeb at Ericsson. GGSN communicates to SGSN and when it receives data variables. It was designed by Ericsson to support fault-tolerant and distributed applications.

Examples of a few built-in virtual ports include: In another embodiment, the system components are implemented in software for example microcode, assembly language or higher level languages. The use edicsson these extensions in connection with the cloud based EPC architecture is discussed further herein below.
The OpenFlow controller does not respond to the calling entity until all flow routing updates have been accomplished.
Gateway GPRS Support Node (GGSN)
A GTP-extended Openflow switch can also accomplish GTP routing without performing the gateway functions of encapsulation and decapsulation. The actions that are defined by the specification of OpenFlow 1.
An example of such special treatment is transcoding. The header flags and message type fields for the three rules are wildcarded with the following bitmasks and match as follows: To rate this item, click on a rating below.
This sends the packet to the software slow path GTP-U decapsulation path for special processing. In one embodiment, the system implements a GTP fast path decapsulation virtual port. Deactivating a control plane module frees up the resources and reduces the overhead created by the control plane module. The subscriber session resources are then reclaimed by deleting the subscriber session and the GTP tunnel.
The embodiments of the present invention provide a method and system for avoiding the disadvantages of the prior art. Communication apparatus, control apparatus, communication system, communication control method, and program. Notifying a controller of a change to a packet forwarding configuration of a network element over a communication channel. GTP tunnels are unidirectional, so each bearer is associated with two TEIDs, one for the uplink and one for the downlink tunnel.

In one embodiment, the system implements handling of GTP-U control packets. Load balancing and monitoring of VM execution to catch crashes provides the same kind of fault tolerance and scalability services for enterprise applications that are achieved at much higher cost with specialized solutions. In other embodiments, the TEIDs can have a correlated meaning or semantics.

The process for deleting a session is illustrated in FIG. This allows the client’s applications within the cloud computing system to operate in a network environment that resembles a corporate WAN.
This implementation technology is favorable for scalable management of the control plane entities within the cloud, since it allows execution of the control plane entities and the controller to be managed separately according to demand. Flow table issuing method and system in software-defined network, open flow controller and open flow switch.
Signal processing apparatus and signal processing method thereof for implementing a broadcast or a multicast communication. Erjcsson following actions push a control plane VLAN tag onto the packet and forward it to the cloud for processing by the relevant control plane entity. This would reduce the amount of traffic that flows into the mobile operator’s core network, thereby reducing the need for expensive and time consuming core network upgrades.
After each flow table match, the actions are accumulated into an action set.
To define a flow, all the available matching fields may be used. If processing requires matching against another flow table, the actions in the matched rule include an action directing processing to the next table in the pipeline. Examples of the non-transitory computer-readable medium include a read only memory ROMa floppy diskette, a CD Rom, a DVD, a flash memory, a hard drive, an optical disc or similar medium. Behind the Scenes at Sprint’s 5G ‘Split’.
The core network is used for transmitting Internet Protocol IP packets.

Ip multicast service join process for mpls-based virtual private cloud networking. Apparatus, and associated method, for multicasting data in a radio communications system.
Communication system and method for providing access to the external network to the wireless terminal. This list is not exhaustive, many other applications of GTP routing on intermediate switches are possible. The rules match the packet filter for the input side of GTP tunnel’s bearer. When the hypervisor moves a VM, it communicates with the virtual switch about the new location, and the virtual switch ensures that the gggsn routing tables for the VM’s addresses L2 MAC address, potentially also the IP address are updated so packets are routed to the new location.
A method for implementing 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 ggzn the PC of the 3G network is in erucsson cloud computing system, the cloud computing system including a controller, the controller to execute a plurality of control plane modules, the ggwn plane to communicate with the data plane of the PC through sfsn control plane protocol, the data plane implemented in a plurality of network elements of the 3G network, ericssonn method comprising the steps of: This allows the packet processing pipeline to mix reicsson match particular rules and actions without causing a combinatorial explosion in the table size.

The ericssoon for modifying a session ggsb illustrated in FIG. This procedure is used in a variety of 3G PC message sequences, for example, a UE triggered service request. However, it should be understood that the operations of the flow diagrams can be performed by embodiments of the invention other than those discussed with reference to FIGS.
A method and a system for optimizing the radio network layer to implement the network interconnection, and a method for interconnection between the radio network and the wired network.
As a result, there is a large duplication of resources and an underutilization of server capacity. The 3G PC architecture also contains little flexibility for specialized treatment of user flows. In other instances, well-known circuits, structures and techniques have not been shown in detail in order not to obscure the understanding of this description. GTP has two components: The control plane entities and the OpenFlow controller are packaged as VMs.
Otherwise, the virtual port constructs a GTP tunnel header and encapsulates the packet.
