Enjoy the peace of mind a fully redundant network infrastructure brings to your company.
ColoMAX delivers one of the most robust, redundant and scalable IP infrastructures in the world. Through our sister division, Xeex Communications client data typically travels on our end-to-end 100% fiber optic IP networks. The following describes a typical ColoMAX facility's network connectivity :
All fiber connectivity is fully redundant utilizing diverse entry into all buildings and diverse routing of fiber connections. In the event there is a fiber cut, all traffic is rerouted over the secondary path within 50 milliseconds.
The ColoMAX facility has two physically diverse circuits (trunks) to other transit hub locations. The access circuits are sized such that 95th percentile offered load at the location can be supported in the event of any backbone circuit failure in the worst case scenario. ColoMAX ensures that upgrades to circuit capacity are ordered when link utilization reaches 45%. This is measured as the 95th percentile of normal traffic (non-outage). When this traffic reaches 45% of circuit bandwidth, additional capacity is ordered. We monitor our traffic using MRTG™.
ColoMAX client connectivity in the IDC (Internet Data Center) consists of Cisco 7600 series ethernet backbone routers and Cisco Catalyst 6500 LAN switches. Clients are connected to the ColoMAX backbone through a layer 2 Cisco LAN Switch via 10/100 Mbps copper, Gigabit Fiber Ethernet or 10 Gigabit fiber ports (based on client's bandwidth requirements). Each client connection is assigned a distinct IP CIDR address block, unless a client is set up in a redundant configuration. Each client connection resides on a separate VLAN that isolates that client’s broadcast traffic from other clients connected to the same Catalyst switch.
In the ColoMAX IDC colocation room the catalyst switches are then meshed via 10 Gigabit Ethernet connections to two distinct Cisco 7600 backbone routers running VRRP (Virtual Router Redundancy Protocol). These Cisco 7600 routers are often referred to as "MAIN" or "Backbone" routers. These Cisco 7600 series routers are then connected via a mesh of OC192 (or 10GE) fiber connections to other backbone routers across the world.
VRRP allows one router to automatically assume the function of the second router if the second router fails providing redundancy. By sharing an IP address and a MAC (Layer 2) address, two or more routers can act as a single "virtual" router. The members of the virtual router group continually exchange status messages. This way, one router can assume the routing responsibility of another, should it go out of commission for either planned or unplanned reasons. Hosts continue to forward IP packets to a consistent IP and MAC address, and the changeover of devices doing the routing is transparent.
ColoMAX addresses QOS traffic engineering issues via the capacity management as described above. ColoMAX also has SLA’s that address packet loss and latency in the network.
