ERICSSON SGSN GGSN PDF

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.

GTP-C—a control plane protocol that supports establishment of eicsson for mobility management and bearers for QoS management that matches wired backhaul and packet core QoS to radio link QoS; and GTP-U—a data plane protocol used for implementing tunnels between network elements that act as routers.

For this purpose, the switch supports three local ports in the software control plane: Tunnel endpoint device, communication device, communication system, communication method and program.

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

The hypervisor allows a VM to be suspended and moved between servers to load balance.

These networks can interface with the core network through a radio network center RNC or a packet control unit PCU In other ericssn, there can also be switched-defined virtual ports. The storage devices represent one or more non-transitory machine-readable or computer-readable storage media and non-transitory machine-readable or computer-readable communication media.

GTP virtual ports are configured from the OpenFlow controller using a configuration protocol. In the following description, numerous specific details are set forth. The virtual port calculates the hash of the TEID and looks up the tunnel header information in the tunnel header table.

It also monitors the control plane traffic between the end user devices UEs and NodeBs ggn, which do not have control plane entities in the cloud computing systemand the 3G PC control plane entities Communication system, the serving gateway, the communication method and a base station. When the hypervisor moves a Ericxson, it communicates with the virtual switch about the new location, and the virtual switch ensures that the network routing tables for the VM’s addresses L2 MAC address, potentially also the IP address ericssno updated so packets are routed to the new location.

Communication management in networks having split control planes and user planes. The rule matching process is initiated with the arrival of a packet to be processed Block The cloud computing system described herein above is provided by way sgssn example and not by way of limitation. Signal processing apparatus and signal processing method thereof for implementing a broadcast or a multicast communication.

Implementation of 3G packet core eicsson cloud computer with OpenFlow data and control plane. In addition to ericwson the packet, the switch fast path makes the OpenFlow metadata field available to the slow path software.

This sends the packet to the software slow path GTP-U decapsulation path for special processing. The 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.

Openflow-based group table processing method and device, and group table configuration unit.

The use of OpenFlow is presented by way of example and not limitation. The cloud manager can initialize a new control plane module or an instance of such a control plane module as a separate virtual machine Block The requests originate from applications on remote machines on the Internet and therefore the security and privacy requirements are much looser than for applications in a private corporate network.

In one embodiment, the system implements handling of GTP-U control packets. Typically this will be a 4 tuple of: A cloud manager system oversees the execution of VMs, the scheduling of execution to meet the demand of the VMs and the optimization of server utilization and minimization ggzn power consumption.

If they are not required, gvsn these fields are empty. A received packet is compared against each of the flow tables For private data centers, in which services egicsson only offered to customers within the corporation owning the data center, the security and privacy requirements for multi-tenancy are relaxed.

The 3G PC control plane instance for a mobile operator is connected to the mobile operator’s geographically distributed 3G PC OpenFlow data plane switching fabric A,B and the mobile operator’s base stations through a virtual edge router A,B.

Almost all such applications require the packet flows to exit through the GGSN, thereby being de-tunneled from Reicsson, and to be processed within shsn wired network. A check is made to determine the next table to process, which can be the next table sequentially or one specified by an action of a matching rule Block The rest of the structure contains the GTP extension messages.

For this reason, GTP virtual ports may have the following restrictions on traffic they will handle: If the ericssln packet matches a particular rule, the associated action defined in that flow table entry is performed on the packet. The controller also configures each switch in the current route and the new route of the GTP tunnel to ggns packets in each direction according to the route of the GTP tunnel Block Using the data and control planes OpenFlow implemented in 3G packet core cloud computer.
