Minimizing network delay or latency is a critical factor in delivering mobile broadband services; businesses and users expect network response will be close to instantaneous. Excess latency can have a profound effect on user experience—from excess delay during a simple phone conversation, reducing throughput at edge of cell coverage areas by reducing effectiveness of RAN optimization techniques, to slow- loading webpages and delays with streaming video. Response delays negatively impact revenue. In financial institutions, low latency networks have become a competitive advantage where even a few extra microseconds, can enable trades to execute ahead of the competition.
The direct correlation between delay and revenue in the web browsing experience is well documented. Amazon famously claimed that every 100 millisecond reduction in delay led to a one percent increase in sales. Google also stated that for every half second delay, it saw a 20 percent reduction in traffic.
For LTE network operators, control of latency is growing in importance as both an operational and business issue. Low latency is not only critical to maintaining the quality user experience (and therefore, the operator competitive advantage) of growing social, M2M, and real-time services, but latency reduction is fundamental to meeting the capacity expectations of LTE-A, where latency budgets will be cut in half and X2 will need to perform at microsecond speed.
Total network latency is the sum of delay from all the network components, including air interface, the processing, switching, and queuing of all network elements (core and RAN) along the path, and the propagation delay in the links. With ever tightening latency expectations, the relative contribution of any individual network element, such as a security gateway, must be minimized. For example, when latency budgets were targeting 150ms, a network node providing packet processing at 250μs was only adding 0.17% to the budget. However, in LTE-A, with latency targets slashed to 10ms, that same network node will consume almost 15x more of the budget. More important, when placed on the S1 with a target of only 1ms, 250 μs is 25% of the entire S1 latency allocation, and endangers meeting the microsecond latency needed at the X2. Clearly, operators need to apply stringent latency requirements for all network nodes, when designing LTE and LTE-A networks.

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

The GGSN is a gateway of GPRS support node independently developed by
IPLOOK. It can be used in either the 2.5G GPRS or the 3G UMTS systems. The
GGSN is a gateway for a mobile station (MS) to access the external packet data

2 Functions
1. APN
This describes the access point name (APN) function of the GGSN. The
APN is a network identifier defined by the general packet radio service/universal
mobile telecommunications system (GPRS/UMTS).
The GGSN must be configured with an APN and the related attributes based
on the packet data network (PDN) to be accessed. Thus, mobile stations (MSs)
under the APN can be connected to the PDN. The GPRS/UMTS core network
identifies a GGSN with an APN. An APN identifies an external PDN that is
connected through the GGSN, or an associated service. The external PDNs
include the Internet service provider (ISP) network and the intranet. The services
include the Internet access service and the Wireless Application Protocol (WAP)
service.
2. GTP
GTP Tunnel
This describes the GPRS Tunneling Protocol (GTP) tunnel function of
the GGSN. The GTP tunnel is used to forward data between the SGSN and
the GGSN.
The data packets from the packet data network (PDN) are GTP
encapsulated on the GGSN, and then forwarded to the SGSN through the GTP
tunnel between the SGSN and the GGSN. The data packets from the SGSN
reach the GGSN through the GTP tunnel. On the GGSN, the packets are
decapsulated, and then forwarded to the PDN.
The GTP tunnel is a bidirectional point-to-point connection. It is defined
jointly by the tunnel endpoint identifiers (TEIDs), User Datagram Protocol
(UDP) port numbers, and IP addresses of the nodes at the two ends.
GTP Signaling Function
This describes the GPRS Tunneling Protocol (GTP) signaling function of
the GGSN. The GTP signaling function consists of tunnel management and
path management.
6. GGSN Product Information
IPLOOK Networks
The information in this document is proprietary to IPLOOK Co, Limited. The information shall not be used,
copied, reproduced or disclosed in whole or part without the written consent of IPLOOK Office of Technology
Development.
3
By means of the tunnel management function, a GTP tunnel is set up
between the GGSN and the SGSN for data transmission. That is, Packet Data
Protocol (PDP) contexts are set up on related nodes. The setup of PDP
contexts consists of activation, deactivation, and update.
By means of the path management function, path management messages
can be transmitted between GSNs (GGSNs and SGSNs) to check whether the
peer GSN exists. When detecting that a path fails, the GGSN deactivates all
the PDP contexts related to this path and no longer transmits data packets
through this path. When detecting that signaling or data is not transmitted
through a path for a long period, the GGSN deletes this path.
IP over GTP and PPP over GTP
This describes two Packet Data Protocol (PDP) types, namely, IP (IPv4
and IPv6) over GTP and PPP over GTP, supported by the GGSN
In the intranet, PPP over GTP can enable enterprises to use the existing
virtual private network (VPN) gateways in fixed networks. The enterprises
need not modify configuration or networking. Thus, users in fixed networks
and mobile networks can be managed in a unified manner. In addition, for
PPP over GTP, L2TP tunnels can be set up or removed in real time. Only the
VPN tunnels that are based on the Generic Routing Encapsulation (GRE)
protocol can be used because IP over GTP is used in the intranet. Thus, the
VPN gateways in the intranet must set up tunnels with all the GGSNs in
advance. The configuration is relatively complex.
IP over GTP and PPP over GTP are two basic functions stipulated in the
3rd Generation Partnership Project (3GPP). PPP over GTP is supported by
some mobile phones and most mobile phones support only IP over GTP.
Intranet users hope to access the intranet through existing LNS and AAA
servers without changing the existing network structure and configuration.
IPLOOK GGSN provides the PPP regeneration solution to meet these
requirements. The GGSN can negotiate with the LNS and set up PPP sessions
based on user information such as the user name and password in user
activation requests.
3. QoS
This describes the quality of service (QoS) function supported by the
GGSN. The general packet radio service/ universal mobile
telecommunications system (GPRS/UMTS) standard defines the QoS in
mobile networks as the end-to-end QoS. The end-to-end QoS depends on the

IPLOOK Networks
The information in this document is proprietary to IPLOOK Co, Limited. The information shall not be used,
copied, reproduced or disclosed in whole or part without the written consent of IPLOOK Office of Technology
Development.
4
QoS features of every node on the transmission path. Thus, when the traffic
passes through the IP-based GPRS/UMTS core network, the GPRS/UMTS
QoS negotiated during the context activation must be mapped to the
differentiated services code point (DSCP) field or type of service (ToS) field
of the IP packet header according to a certain mapping rule. An IP QoS
performs queue scheduling to ensure the end-to-end QoS.
The GGSN supports QoS negotiation and mapping.
The QoS requested is carried in the context activation request message of
a mobile station (MS). The GGSN performs the QoS negotiation based on the
QoS information and the configurations of the GGSN. The GGSN maps the
negotiated QoS parameter into the differentiated services (DiffServ) priority
of the IP network, fills the priority into the ToS or DSCP field in the header of
the packets, and then forwards them to an external packet data network (PDN).
The PDN schedules the IP QoS queue to ensure the QoS of the packet service.
The GGSN supports the user-based Different Service.
The services at different levels are provided for users who have different
requirements. The allocation/retention priority (ARP) in activation requests
controls the access and bearer priority of users. To meet DiffServ
requirements, the GGSN provides different QoS levels based on user levels
and traffic classes.
4. Charging
The GGSN can provide abundant charging functions and enable operators to
charge users flexibly.
RADIUS Accounting
This describes the Remote Authentication Dial In User Service
(RADIUS) accounting function of the GGSN.
RADIUS accounting refers that the GGSN sends charging data of a
mobile station (MS) to an authentication, authorization and accounting (AAA)
server and the AAA server performs the accounting function. With the
RADIUS accounting function, the GGSN can implement both non-real-time
charging and quasi-real-time charging so that mobile operators and Internet
operators can separately charge users.
8. GGSN Product Information
IPLOOK Networks
The information in this document is proprietary to IPLOOK Co, Limited. The information shall not be used,
copied, reproduced or disclosed in whole or part without the written consent of IPLOOK Office of Technology
Development.
5
The GGSN allows the RADIUS server to assign IP addresses to users
during RADIUS authentication and deactivates a user after receiving the
Packet of Disconnect (PoD) message from the RADIUS server.
The GGSN allows you to configure a RADIUS server for each access
point name (APN). The RADIUS servers, namely, AAA servers, can operate
in active/standby mode or load-sharing mode.
Offline Charging
This describes the offline charging function of the GGSN.
The GGSN generates GGSN charging data records (G-CDRs) and sends
them to the charging gateway (CG) through the Ga interface for processing.
Then, the G-CDRs are sent to the billing system (BS) for charging processing.
The G-CDRs are the data service records generated by the GGSN, which
record charging information about the packet data network (PDN) usage. The
GGSN creates and opens CDRs to start charging when Packet Data Protocol
(PDP) contexts are activated for mobile users. It closes the CDRs and stops
charging when the PDP contexts are deactivated. Each activated PDP context
has its CDRs.
The GGSN supports CDRs of multiple versions such as R98, R99, R4,
R5, R6, and R7.
Online Charging
This describes the online charging function of the GGSN.
The Diameter Credit Control Application protocol is extended based on
the basic Diameter protocol. This application protocol defines the charging
mechanism for online charging users and realizes session-based charging by
controlling the credit limit in real time. Therefore, this application protocol
meets the requirements of the Diameter online charging on the GGSN.
When an online charging user starts a data service, the online charging
system (OCS) can determine whether the service is allowed based on the user
information and the balance of the user account. The online charging function
can trace the usage (time or volume) of the resources prepaid by the user and
deduct the current usage expense from the account balance in real time. The
service is automatically terminated or the user is informed when the account
balance is exhausted.

The GGSN supports the policy and charging control (PCC) feature and
provides a PCC solution.
Based on the PCC feature, operators can perform unified and multi-
dimension policy deployment and control in network operation, thus preventing
channelized services and enhancing competitiveness by optimizing network
resource usage and improving network user experience.
The GGSN supports the following PCC functions:
Static PCC control: Where PCRF is not deployed, all policies are
implemented by the Policy and Charging Enforcement Function (PCEF)
according to the local static configuration.
Dynamic PCC control: Where AF may exist after PCRF is deployed, all
services dynamically generate PCC rules for scheduling and charging
based on their own QoS requirements and subscription data.
