Hybrid
Configure the Hybrid tunnel traffic information between UE and HAAP (Hybrid Access Aggregation Point). The HAAP acts as a service termination and a service creation point and sets up a high speed internet dual stack IP connection on top of both access technologies.
| NOTE: GRE encrypted packets can only be decrypted via DT wireshark plugin. |
Indicates a unique Client Identification Name (CIN) sent from HAAP during tunnel establishment. CIN is unique for Hybrid Access Aggregation Point (HAAP) each HG. Tcl Parameter: HgClientId |
|||||||||

|||||||||
Configure the RTT threshold for changing bonding to DSL GRE tunnel on HG from HAAP. Indicates the maximum length of time allowed for a signal to be sent plus the length of time it takes for an acknowledgment of that signal to be received.

Used while tunnel is in Active mode. Idle Hello interval will be used when tunnel is in Idle mode. This attribute is included in the GRE Setup Accept control message for LTE tunnel. Options: 1 - 4294967295 Default: 10 Tcl Parameter: HgHelloInterval |

|||||||||
Indicates the length of time to wait without sending a Hello message or receiving an acknowledgement. If tunnel connection is already established via DSL path, idle timeout occurs and all tunnel connections MUST be terminated if LTE tunnel connection is not restored within configured tunnel idle timeout. Options: 1 - 4294967295 Default: 120 Tcl Parameter: HgIdleTimeoutDefault |
|||||||||
Used when Tunnel is in Idle State. As soon as Tunnel switches to Active state, Hello messages will be based on Hello Interval. As soon as HG session is established or when no overflow traffic (in both directions US/DS) for the duration of Traffic Monitoring Interval, HG will switch to Idle hello state, The hello message will be sent based on "Idle Hello Interval". Options: 0 - 65535 Default: 300 Tcl Parameter: HaapIdleHelloInterval |
|||||||||
Used to monitor traffic in the tunnel. When there is no traffic for the duration of this interval, the state will be detected as "Idle" and switch to "Idle State". During the Idle state, the Hello interval will be switched to Idle Hello Interval. Options: 0 - 65535 Default: 180 Tcl Parameter: HaapTrafficMonitoringInterval |
|||||||||
Indicates the delay deviation threshold violation of both LTE and DSL link. The HA traffic packets use two paths (DSL and LTE) for transport; the links between HG and HAAP have different characteristic such as rates, RTT/delay that impact the throughput. The rate, RTT/delay of a DSL link is relatively fixed, but these characteristics of an LTE link vary over time. In general, LTE link‟s RTT/delay are larger than DSL‟s. When the DSL and LTE link are combined in a HA tunnel, the HA tunnel has a large combined bandwidth (DSL_BW + LTE_BW). However, the HA tunnel may also have a larger RTT/delay characteristic of the link. Usually the maximum RTT/delay of HA tunnel is equal to the RTT/delay of LTE link. A mechanism of packet buffering and reordering is used to achieve an as small as possible packet delay by the HA tunnel. The buffering size is related to the RTT/delay difference between both LTE and DSL link. The calculation formula of buffering size for HG downstream, for example, if the RTT/delay deviation between DSL and LTE link is 10ms, DSL downstream bandwidth is 50Mps, then the buffering size is: 10ms×50Mbps/8＝ 62.5KB. Because the LTE RTT changes over time, in some case the RTT will deteriorate and the RTT/delay deviation of both LTE and DSL link may become so big that the throughput of the HA tunnel drastically decreases. A switch mechanism is implemented to resolve this problem. A maximum delay threshold MaxThreshold_RTT_Deviation is defined and is configurable from 0 to 1000 milliseconds. If the delay threshold is reached, the traffic must pass the tunnel using only the DSL tunnel. Options: 1 - 4294967295 Default: 5 Tcl Parameter: HgDelayDiffThresVio |
