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.

In the following description, numerous specific details are set forth. An action allows the writing of data to a metadata register, which is carried along in the packet processing pipeline like the packet header.
The coupling of ggsm set of processors and other components is typically through one or more busses and bridges also termed as ericswon controllers. The data plane consists of standard OpenFlow switches with enhancements as needed for routing GTP packets, rather than IP routers and Ethernet switches.
Additionally, the 3G PC control plane entities themselves can issue event notifications to the cloud manager if they detect internally that they are beginning to experience overloading. Examples of a few reicsson virtual ports include: Future of Cable Business Services.

In some situations, managed services companies build and run mobile operator networks, while the mobile operator itself handles marketing, billing, and customer relations. The parsing process matches a packet header by initializing a set of match fields Block and checking for the presence of a set of different header types. There is currently no organizational mechanism to register type identifiers in OpenFlow. The cloud manager can perform these functions across VPCs and mobile operators using the cloud computing system resources, thereby maximizing the use of available resources and reducing the cost of operation while maintaining strict separation of data and traffic between mobile operators.
It will be appreciated, however, by one skilled in the art, that the invention may be practiced without such specific details. The managed services cloud computing facility runs separate instances of the 3G PC control plane for every mobile operator with which the managed services company has a contract. Architecture for seamless enforcement of security policies when roaming across ip subnets in ieee Otherwise, the virtual port constructs a GTP tunnel header and encapsulates the packet.

The cloud computing system of claim 8wherein the controller is configured to receive a request to modify the GTP tunnel in the PC of the 3G network between the SGSN and GGSN for the subscriber session, the controller is configured to modify configuration of the switch implementing the data plane of the SGSN, via the control plane protocol, to encapsulate and decapsulate packets of the subscriber session and to modify the first GTP tunnel endpoint, and the controller is configured to modify configuration of the switch implementing the data plane of the GGSN, via the control plane protocol, to encapsulate and decapsulate the packets of the subscriber session and to modify the second GTP tunnel endpoint.

Almost all such applications require the packet flows to exit through the GGSN, thereby being de-tunneled from GTP, and to be processed within the wired network. If necessary, the message specifies actions and instructions, as described above, to establish a new flow route for the GTP tunnel that encapsulates and decapsulates the packets through the appropriate virtual port.
The hypervisor and the virtual switch can thereby co-operate to allow VMs to be moved between servers. QoS is necessary because, unlike fixed networks, the wireless link is severely constrained in how much bandwidth it can provide to the terminal, so the bandwidth needs to be managed more tightly than in fixed networks in order to provide the user with acceptable quality of service.
In other embodiments, the split 3G PC architecture can be implemented in non-cloud and non-virtualized systems.

The use of these extensions in connection with the cloud based EPC architecture is discussed further herein below. The split between the control and data plane parts of the 3G PC can be used together with virtual private cloud VPC technology to implement multiple PoPs within a single 3G PC, provide GTP flow-specific routing for specialized applications, and run multiple operator networks from a single cloud computing facility. Once all of the tables have been processed, then the resulting action set is executed Block Communication management in networks having split control planes and user planes.
To realize a certain network QoS Service with clearly defined characteristics and functionality is to be set ggan from the source to the destination of a service. This sends the packet to the software slow path GTP-U decapsulation path for special processing. When an incoming packet is received a lookup for a matching rule is made in the flow table For encapsulation virtual ports, the physical port is an output port.

The physical sgsnn of the OpenFlow control plane can be as a completely separate physical network, or it may be a virtual network running over the same physical network as the data plane, implemented with a prioritized VLAN or with an MPLS label switched path or even with a generic routing encapsulation GRE or other IP tunnel. In addition to the flow table fields, an object is required to encode the encapsulation of the virtual port TEID hash table entry. The configuration command must be run in a transaction so that, when the results of the action are reported back to the controller, either a GTP-U fast path virtual port for the requested datapath has been instantiated or an error has returned indicating why the request could not be honored.
Communication system, serving gateway, and communication method and base station therefor. These control plane entities can communicate with one another through local system or procedure calls, remote procedure calls or similar mechanisms.
Cases where such treatment might be required are, for example: Similar principles and features to those described above can be implemented in single server systems, distributed server systems and similar computing environments. A modification process can be utilize to re-route a subscriber session across the 3G PC network to the same endpoints or to different endpoints. So, for instance, a Google query from a smartphone would be routed via the SGSN to the GGSN and sent on as a query to the Internet search engine, then the process would be reversed for the reply to the phone user.
