Service overview

Colt Ethernet Line (point-to-point) / Hub & Spoke (point-to-multipoint) are low-latency, reliable, and bandwidthguaranteed Ethernet lines. With traffic between data centres increasing year over year, these circuits offer uncompromising performance while reducing cost of access and use. Choose between guaranteed bandwidth (CIR*1=PIR*2), or partial guaranteed bandwidth with burstability (CIR < PIR).

*1 CIR: Comitted Information Rate
*2 PIR: Peak Information Rate

Connectivity overview

Features

Ultra-low
latency
  • Colt has a proven track record in serving the financial industry with low-latency connectivity and we continue to leverage that experience to shrink latency down to the microsecond.
  • Expertise in developing our own fibre-optic network has made us industry leaders in low latency
  • We use low-latency optimised network equipment on top of our efficiently configured core network to tune latency down even further.
High quality
  • Our core network is entirely redundant, with optional redundancy in client access lines
  • Reliable quality assurance SLAs (availability, bandwidth recovery, incident time to recovery, lead times)
  • Guaranteed end-to-end bandwidth boasts a fast switching (<50ms) leased line in case of outages, and a wide array of features such as 1Mbps to 6Gbps bandwidth packages and reporting features not found in other leased lines
Flexibility & scalability
  • Simple bandwidth upgrades without requiring physical onsite changes/installation
  • High-bandwidth lines up to 1G can be setup within 10 business days if circuit equipment already exists
  • All customers furnished with access links of up to 1 to 10Gbps to allow for bandwidth flexing without extra physical installation or equipment upgrades.
Inter-DC
connectivity
  • A fast, all-in-one connectivity service with inter-connects between over 70 major centers in Asia already
  • High-bandwidth connection of up to 10Gbps between data centres

Hikari Access option

Best-effort Hikari Access is useful for access points that don’t use a lot of traffic or are transmitting data that is less important. Get optimal cost and performance by using Hub & Spoke to combine guaranteed bandwidth and burstability.
