Communication service providers (CSP) are currently spending large amounts of money to deploy 4G and advanced networks. Historically CSP's have managed scaling and performance of networks by increasing bandwidth and spending more money on frequencies and hardware. However with 4G networks being all IP, CSP's now must take into account more elements in dealing with the scaling and performance of their networks. With all-IP networks scaling becomes more dependent upon designing and developing inte...
On April 15th, 2011, the last of the IPv4 address blocks was allocated,. Due to IPv4 address depletion, migration to IPv6 is inevitable. This migration to IPv6 will ease IPv4 address depletion but it does not address other significant networking issues such as security. Networks that have already migrated to IPv6 are starting to experience the first Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks. These attacks can lead to significant amounts of downtime and, especially ...
Domain Name System (DNS) is one of the overlooked systems in the deployment of 4G and Next Generation All IP Networks. The focus tends to be on revenue-generating applications that provide ROI for these major investments. For these to be successful the CSP's have first got to be able to deploy these networks, and provide a high quality of experience in order to be sure that these services are truly revenue generating. However, most CSP’s have overlooked some of the basic IP functions in order to...
With the development of Internet Multimedia Services (IMS), the challenge of defining how the IMS infrastructure would deliver application services and control the user experience was answered with Policy. Policy is simply the application of business rules to define how a subscriber interacts with the network, application and services. Since 3GPP included Policy into the IMS standards,(3GPP TS 23.203) the market has viewed Policy as simply bandwidth management and subscriber tiered services. How...
Over the last 10 years, there have been a lot of discussions about the depletion of IPv4 addresses.   With development of the IPv6 standards, general consensus is that the Internet will eventually transition to IPv6.  The real question has been “When will this transition take place?” For Communication Service Providers (CSP), increases in data usage and IP devices have caused industry standard’s bodies (such as 3GPP, TiSpan, 3GPP2 and CDG) to incorporate IPv6 in their high speed network archite...
