Updates to the core network, the capacity of external connections increased up to 360 Gbp/s, DDoS protection
The capacity of WaveCom's core network and external IP Transit connections has quintupled in the last two years. The new core network is powered by two powerful Cisco ASR 9902 routers, strategically located in separate data centers. Additionally, three Cisco Nexus 9300 series Data Center network switch clusters, each capable of handling 5 TBit/s, are deployed. In total, the volume of our external connections is a significant 360 GBit/s.
The capacity of WaveCom's core network and external IP Transit connections has quintupled in the last two years. In our data centers, we use three clusters of Cisco Nexus 9300 series Data Center switches with a capacity of 5 TBit/s. Each cluster contains 2 switches operating in multihomed mode and are connected with aggregated connections of 200 Gbit/s, forming the core network. They are connected to dual-homed 40 Gbit/s speed fabric extenders in device cabinets, which replace Top-of-Rack switches. We currently offer speeds of 1/10/40/100 Gbit/s to our clients.
The heart of the new core network consists of powerful, two Cisco ASR 9902 routers, located in different data centers. The data routing capacity of the ASR 9902 router is up to 1.6 Tbit/s. Each router has two routing processors, two logical line cards (consisting of 10/25/40/100 Gbit/s network ports), redundant power units and fans. If a component fails or a malfunction occurs, this failure or maintenance work on the component does not affect the operation of the device.
Each router is connected with a 100 Gbit/s Arelion/Twelve99 (formerly Telia Carrier) and 40 Gbit/s Citic Telecom external IP Transit connection, which use different submarine cables. There are also 40 Gbit/s connections with the RTIX internet access point, through which a large part of domestic network traffic passes. Thanks to the diversity of transit operators, we are able to offer the best communication quality with different world´s internet networks.
Additionally, we are currently capable of fending off DDoS and other congestion attacks. The system is activated automatically when a network attack is detected and the network traffic is routed through routers that clean network traffic, which filter out undesirable and dangerous traffic and only allow clean network traffic to pass.
Our network traffic does not stop even during router maintenance, because clients network connections use the HSRP protocol – this means that a virtual IP address shared between two routers is used, which the servers, in turn, use as their default gateway. If one router stops working, the virtual IP moves automatically to the working router and network operation continues without packet lossess.
If a router or switch should completely stop working, the device's operation would continue normally on its pair, using VPC (Virtual Port Channel) and Dual-homed FEX technology at the L2 OSI model level, and OSPF, IBGP and HSRP technology at the L3 level.
We offer our clients BGP sessions, the possibility to use their own AS numbers and IP address space, as well as the use of private AS numbers and our address space. We also offer you the opportunity to provide transit connection to your clients and AS numbers.
We also contribute to making the global internet safer by filtering incoming internet routings according to RPKI ROA record compliance comparison. This significantly helps to reduce BGP-related attacks or incorrect routings.
