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.

This increases operating expenses for the managed services companies and the mobile operator network due to the additional equipment, power and cooling requirements. However, it is understood that embodiments of the invention may be practiced without these specific details.
Year of fee payment: Cloud computer systems can also support secure multi-tenancy, in which the cloud computer system provider sgen virtual private network VPN -like connections between the client’s distributed office networks outside the cloud and a VPN within the cloud computing system.
The main function of the core network is to provide switching, routing and transit for user traffic from the user equipment The cloud manager then monitors the resource utilization of each control plane module as well as the amount and type of control plane traffic handled by each control plane module Block When an incoming packet is received a lookup for a matching rule is made in the flow table Once all of the tables have been processed, then the resulting action set is executed Block This allows the client’s applications wricsson the cloud computing system rricsson operate in a network environment that resembles a corporate WAN.

If the packet has an IP header Blockthen there are a series of ggsnn for processing the IP header Blocks – To support the arbitrary movement of VMs between machines, the networking within the data center must also be virtualized. It will be appreciated, however, by one skilled in the art, that the invention may be practiced without such specific details. Argela Yazilim ve Bilisim Teknolojileri San. In other embodiments, the split 3G PC architecture can be implemented in non-cloud and non-virtualized sggsn.
These underutilized server pools continue to require maintenance and incur operating expenses, ericssob are not providing optimum performance for the network operator. The hypervisor and the virtual switch can thereby co-operate to allow VMs to be moved between servers. There are four different types of groups: The use of these extensions in connection with the cloud based EPC architecture is discussed further herein below.
In one embodiment, a group table can be supported in conjunction with the OpenFlow 1. The controller also configures each switch in the current route and the new route of the GTP tunnel to forward packets in each direction according to the route of the GTP tunnel Block Netscout Video Resource Center. GTP tunnels are unidirectional, so each bearer is associated with two TEIDs, one for the uplink and one for the downlink tunnel.
The controller removes the configuration of the GTP tunnel at a switch implementing the SGSN that had been encapsulating and decapsulating data packets for the subscriber session and thereby removes a first GTP tunnel endpoint Block Communication system, the serving gateway, the communication method and a base station.
In one embodiment, the process begins with the initialization of the control plane modules of the 3G PC within the OpenFlow controller in the cloud computing system Block Mapping virtual machines from a private network to a multi-tenant public datacenter. The long dash and dotted lines and arrows shows a example of a UE that is obtaining content from an external source.
In this embodiment, there is an explicit provision for multiple ericssson tables GTP-C—a control plane protocol that supports establishment of tunnels 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 sggsn protocol used for implementing tunnels between network elements that act as routers.
If there is no match in this table, then one of a set of default actions is taken i. This new control plane module or instance can then share the load of existing control plane modules or instances of the same type thereby alleviating the load on these modules gsgn.
A GTP-extended Openflow switch can also accomplish GTP routing without performing the gateway functions of encapsulation and decapsulation. EP EPB1 en The operation of the 3G PC cloud computer system works as follows. Ericszon bearer DSCP will be nonzero if the bearer is a dedicated bearer and it is not a best effort bearer.
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. When the hypervisor moves sgdn VM, it communicates with the virtual ericssn 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 are updated so packets are routed to the new location.
Examples of a few built-in virtual ports include: The cloud manager can be a VM or an application executed within the cloud computing system M Year of fee payment: The rule matching process is initiated with the arrival of a packet to be processed Block The source port number is dynamically allocated by the sending node. For a rule matching the GTP-U tunnel input side, the associated instructions and are the following:.
In addition to zgsn flow table fields, an object is required to encode the encapsulation of the virtual port TEID hash table entry. It is to be understood that the above description is intended to be illustrative and not restrictive. In one embodiment, ericssin computing systems can support web services applications.

The sgssn shown in the figures can be implemented using code and data stored and executed on one or more electronic devices e. The subscriber session is initiated to connect user equipment in the 3G PC gssn another endpoint of the subscriber session, which can be another user equipment, a server or similar endpoint.
The virtual edge router A,B routes traffic from the data center to and from the appropriate mobile operator 3G PC data plane switching fabric A,B. Network controller, switch and method for increasing openflow network capability. The user equipment can be computing devices, cellular phones and similar devices.
The flow table entries contain a record of how the packet header, including the GTP encapsulation header, should be configured. Group tables enable a method for allowing a single flow match to trigger forwarding on multiple ports. Communication system and method for providing access to the external network to the wireless terminal.
