IP RAN Optimization with a Migration Path for 2G and 3G Sites over one Backhaul Network.

March 19, 2013 | By More

Cellular optimization significantly reduces costs, particularly in OPEX-intensive backhaul environments such as satellite: Mobile traffic aware transport is required to achieve 50% savings while enhancing the user experience. Sevis’ IP Optimization solution processes IP traffic using a multi-stage optimization algorithm designed specifically for mobile networks.

The stages are defined as:

  • Network Domain: Process incoming traffic and apply mobile traffic aware intelligent optimization techniques to ensure the network is using the most efficient voice codecs, reserving the proper number of resources for packet service, and prioritizing access domain mobile traffic.
  • Application aware: Integration with third party vendors to provide solutions such as remote switching.
  • Transport: IP traffic is processed at OSI layers three through six. A proprietary mobile network tailored Robust header Compression (RoHC) algorithm is applied. This mobile network aware version of RoHC treats the forward and backward IP paths independently, supporting multiple IP route QoS network architectures. Packet aggregation of UDP traffic is applied using multiple queues, each with independently configured user defined priority and temporal depth (latency). Packet variation is preserved across WAN interfaces and precisely recreated at the far end node. UDP, TCP, and SCTP traffic is independently processed. Finally, independent QoS tags are applied to outgoing traffic.
  • Media: A lossless compression algorithm is applied to all outgoing WAN traffic along with support for standard or jumbo Ethernet frames. Integration between the optimizer and satellite modem is supported enabling dynamic traffic processing based on satellite link capacity. The IP Optimizer operates in bridged mode eliminating network reconfiguration or changes to network routing.

The IP Optimization solution also supports auto-discovery of mated pairs eliminating the need for coordinating installation of hub and remote sites. It also prevents network downtime due to misconfiguration of systems. Deployments are fast and require no coordination between sites.
