The SynergyWorks Network

The SynergyWorks network is serviced by enterprise class HP Procurve switching. The core routers take feeds from multiple diverse upstream providers and utilise multiple peering arrangements. Multiple routers are then used at each core network site, configured in VRRP groups to provide additional fault tolerance. Should one router fail the remaining routers will continue to service customers without interuption. This multihomed and multi-router setup allows us to provide low latency high availability solutions for mission critical deployments.

Core Network: London Docklands

• Routing Sites
  Our core network is located in London Docklands. We have two network cores, one located in Telehouse East, the other in Telehouse North. Telehouse is home to most of the UKs largest carriers including Level3, AboveNET and Cogent. It is also home to the UKs major broadband providers such as BT and Virgin Media. By locating our core network in Telehouse we are able to provide fast low latency access to UK and European networks.

• Connectivity
  The SynergyWorks routers are fed with multi-gigabit connectivity from upstream carriers carefully selected for their quality of routing and reliability. These upstreams provide BGP4 sessions. This allows us to seamlessly failover between carriers and hand pick the best routes from each provider.

• Redundancy
  We have two routers in Telehouse East and two routers in Telehouse North, plus fibre connectivity between the two sites. During normal network conditions our policy is to route connectivity over the best path available. The network is engineered that should a router or either core routing site fail; traffic will automatically be re-routed over the remaining sites or connections. We only need one core network site, one router and one upstream carrier to service customers. The likelihood of us loosing both routing sites and both routers in each is near zero.

Hosting Network: Kent Science Park

• Connectivity
  We operate a redundant fibre ring at the Kent Science Park with fully meshed switching. Facility 1 (F25) has fibre to Telehouse North whilst Facility 2 (B810) has fibre to Telehouse East. These two fibres take physically diverse paths. Fibre between the two facilities then completes our ring. Under normal network conditions traffic flows the shortest way around the ring. Should either fibre leg fail traffic simply flows the opposite way keeping both facilities online. This is an automated process which takes place in a matter of milliseconds.

• Redundancy
  Switching at the Kent Science Park is fully meshed. We also operate Dual PSU switching in core cabinets to ensure reliability. In the Building 810 N+N facility switching takes two power feeds, one from System A and one from System B.
