Networking

Reduce complexity. Increase availability and agility

Better networks. Simplified

Organisations face numerous challenges when it comes to data centre networking, not least of which are the lack of specific expertise, resources and time to devote to this vital area of IT. We use our knowledge and experience to design network solutions that offer agility, availability and simplicity, not to mention performance, scalability and security.

Agility

Agility

We deliver agility through virtualisation and automation. VXLAN (virtual extensible LAN) and MPLS (multiprotocol label switching) are the two main virtualisation technologies we use. We also use automation technologies, such as NETCONF, Ansible and, in some environments, Chef and Puppet, to remove lots of time-consuming, error-prone manual tasks.

Availability & scalability

Availability & scalability

All modern data centre network environments are some sort of 'fabric', comprised of small but powerful switches webbed together. This makes them robust. Any device can fail, without the entire network going down or losing significant amounts of bandwidth. These fabrics can also scale up and down, from a few switches with tens of servers, to 100 switches and thousands of servers.

Simplicity

Simplicity

The simplest fabric is an L3 fabric which only connects hosts/switches/routers on L3. This way, each server or service will have IPs from different subnets. This is easy for cloud-ready applications but not good for old-fashioned enterprise applications. For these, an L2 fabric will be better, where L2 (switching) is done over L3 (routing). Here, eVPN/VXLAN and eVPN/MPLS are the most promising technologies/protocols.

Performance

Performance

We achieve high performance in several ways. We bundle 40-100 Gigabit Ethernet cabling together and take an equal cost multipath (ECMP) strategy, where there are multiple 'best paths' for each data packet to take. We use a dual or multiple leaf-spine design, to help compensate for a single hub loss, without a major decrease in bandwidth or an increase in latency.

 

Security

Security

Maintaining confidentiality and integrity over links that could possibly be tapped is essential. We achieve this by adopting the MACsec (the IEEE MAC Security) standard for encrypting Ethernet links up 100 Gigabit. Modern data centre switches already support MACcec on every type of connection (from uplink routers, via the fabric links, down to the servers). We also offer SIEM as a Service.
