| Basic Set-up |
- In general, HKIX can provide at most four IP addresses (two 202.40.161.x and two 2001:7FA:0:1:: CA28:A1XX) to each participant at HKIX primary site and four IP addresses (two 218.100.16.x and two 2001:7FA:0:1:: DA64:10XX) to each participant at HKIX secondary site (i.e. HKIX2).
|
- HKIX supports at most one IPv4 and one IPv6 address per connection to each participant on HKIX switch per HKIX site.
|
- HKIX can provide at most two 10/100/1000BaseT network connections to each participant on HKIX switch per HKIX site.
|
- HKIX can accept SDH, SONET or ATM connection to HKIX with speed of 1.5Mbps or above only if the link layer of the circuit is terminated at the participant’s co-located router at HKIX site. While HKIX will provide 10/100/1000BaseT switch port for the participant’s co-located router, HKIX will not provide any other layer 1, layer 2 or layer 3 equipment port such as ATM port or router port for that circuit.
|
- HKIX does not support trunk or VLAN mapping to our switch at both HKIX sites.
|
- HKIX will turn on port security with the MAC address connected from participant's router to the HKIX switch. At any time, only one MAC address will be allowed on each HKIX port and HKIX participant must inform HKIX NOC by email if there is any change or maintenance on the router MAC address.
|
- HKIX can provide up to 10U vertical rack space per connection to accommodate participant’s co-located router. However, HKIX will not provide space for co-location of other switching or transmission equipment. All other switching or transmission equipment must be installed in Fixed Telecommunication Network Services Operator‘s equipment rack.
|
- The basic set-up is free of charge and no formal agreement is needed to be signed between HKIX and the HKIX participant as long as the participant has fulfilled all the requirements for becoming a HKIX participant as stated in http://www.hkix.net/hkix/policies.htm.
|

| Advanced Set-up |
- Subject to the availability of switch ports at HKIX, HKIX can provide more than two 10/100/1000BaseT ports or 10GE port(s) to HKIX participants at each HKIX site. However, before granting the additional port or a 10GE port to the requesting participant, an agreement has to be signed between HKIX and the particular HKIX participant. The main purpose of the agreement is to avoid HKIX’s precious resources of critical Internet infrastructure being abused.
|
| The basic idea of the agreement is as follows: |
- When the agreement is in effect, an additional GE port or 10GE port will be assigned to the requesting HKIX participant and the aggregate network traffic usage of the HKIX participant at all the HKIX sites will be collected and monitored on a monthly basis based on the 95th Percentile Aggregate Usage (95PAU) principle.
|
The 95PAU principle is explained as below:
- The aggregate network traffic collection period is commencing on the 1st day of each calendar month 0:00:00 HKT to the end of the calendar month 23:59:59 HKT.
|
- The aggregate network traffic is measured as the total number of Mbps received and sent on all the network ports of that participant at all the HKIX sites.
|
- The network ports are polled every 5 minutes collecting a sample containing both incoming and outgoing usage over the calendar month, and then being summarized, resulting in 8,640 samples for inbound and 8,640 samples for outbound traffic samples (for a 30-day month).
|
- The inbound and outbound data samples are then ordered from the lowest to the highest. The top 5% of the data sample are discarded and the usage corresponding to the 95th inbound and 95th outbound are selected. The higher of the 95th inbound usage and 95th outbound usage is chosen which gives the “95PAU”.
|
- The 95PAU is rounded down to the nearest 1 Mbps.
|
- If the 95PAU of the requesting participant in any calendar month falls below 50% of the total bandwidth of all the network ports of the participant at all the HKIX sites, the HKIX participant needs to pay a special charge for the new/additional port(s).
|
For example:
- If a participant has 2 x GE and adds the 3rd GE at HKIX primary site and
- If its 95PAU < 1.5Gbps, it has to pay a special charge for 1 x GE (i.e. the 3rd GE)
|
- If the same participant above (having 3 x GE at HKIX primary site) adds the 4th GE at HKIX primary site and
- If its 95PAU < 2Gbps but >= 1.5Gbps, it has to pay a special charge for 1 x GE (i.e. the 4th GE);
- If its 95PAU < 1.5Gbps, it has to pay a special charge for 2 x GE (i.e. the 3rd and the 4th GE).
|
- If the same participant above (having 4 x GE at HKIX primary site) adds the 1st GE at HKIX2 and
- If its 95PAU < 2.5Gbps but >= 2Gbps, it has to pay a special charge for 1 GE (i.e. the 4th GE at HKIX primary site);
- If its 95PAU < 2Gbps, it has to pay a special charge for 2 x GE (i.e. the 3rd and the 4th GE at HKIX primary site).
|
- If another participant has 2 x GE and adds a new 10GE at HKIX primary site and
- If its 95PAU (i.e. of its 2 x GE and 1 x 10GE) < 6Gbps, it has to pay a special charge for the 10GE.
|
- For 10GE connection, HKIX participant needs to provide its own module such as Cisco XENPAK module (XENPAK-10GB-LR) or its equivalent for fiber termination. To enquire the latest specification of the optical modules for 10GE connection at HKIX, please send e-mail to hkix-noc@cuhk.edu.hk .
