Recent additions to our global network are: Massive investments in fiber capacity and diversity across metro, terrestrial, and submarine paths are crucial for us to keep consistent and high service-level while fueling the extreme growth of our cloud and online services. This routing ensures optimal performance and integrity. So, does that mean all traffic when using Microsoft services? Yes, any traffic between data centers, within Microsoft Azure or between Microsoft services such as Virtual Machines, Microsoft 365, XBox, SQL DBs, Storage, and virtual networks routes within our global network and never over the public Internet. Traffic stays on Microsoft network as long as possible before it's handed off. This data travel is referred to as cold-potato routing. This approach ensures symmetric response traffic and helps to minimize hops, peering parties, and paths to keep them as short and simple as possible.įor example, if a user in London accesses a service in Tokyo, the Internet traffic enters one of our edges in London, travels over the Microsoft WAN through France, our Trans-Arabia paths between Europe and India, and then to Japan where the service resides. At Microsoft, we choose and utilize direct interconnects instead of transit-links. Whether connecting from London to Tokyo, or from Washington DC to Los Angeles, latency, jitter, packet loss, and throughput affect network performance. These edge-nodes, all interconnected to more than 4000 unique Internet partners (peers) through thousands of connections in more than 175 locations, provide the foundation of our interconnection strategy. From the moment when customer traffic enters our global network through our strategically placed edge-nodes, your data travels through optimized routes at near the speed of light. Opting for the best possible experience is easy when you use Microsoft cloud. The Microsoft global network offers both the availability, capacity, and the flexibility to meet any demand. The global network connects our Microsoft data centers across 61 Azure regions with a large mesh of edge-nodes strategically placed around the world. The Microsoft global network (WAN) is a central part of delivering a great cloud experience. Regardless of type, customers expect instant reliability and responsiveness from our services. This global and sophisticated architecture, spanning more than 165,000 miles, connects our datacenters and customers.Įvery day, customers around the world connect and pass trillions of requests to Microsoft Azure, Bing, Dynamics 365, Microsoft 365, XBox, and many others. Compared to a conventional networking method using appliances (DPI / VPN Tunnel) and routers, the hybrid engine architecture is better at reducing CAPEX / OPEX / power consumption because it can eliminate performance bottlenecks and reduce the number of appliances / physical lines by implementing functions on an NP directly connected to the internal path of a router.Microsoft owns and operates one of the largest backbone networks in the world. ![]() The merits of the hybrid engine architecture are not limited to fast routing and flexibility. Further, by specifying the NP of a service module card (SMC) as a packet forwarding destination, it becomes possible to provide upper-layer optional functions (e.g., security, accounting) using the NP. The AX8600R series performs packet format conversion / labeling for tunneling with its programmable engine (PE) serving as NP on a line card, and performs the basic forwarding functions of routers (e.g., packet relay, QoS, filtering) at a fast rate with its forwarding engine (FE) according to a label (ASIC-NP cooperative function). The AX8600R series employs hybrid engine architecture, which can achieve high-performance, high-flexibility packet forwarding with cooperative operations between ASIC (Application Specific Integrated Circuit) and NP (Network Processor). ![]() Therefore, packet forwarding devices in networks must be capable of tunnel session management, fast packet forwarding via tunnels, flexible linkage between a tunnel and QoS / DPI, etc. In mobile networks, various kinds of services (e.g., voice transmission, data transmission, mobile virtual network operators) are provided via a tunnel established between a base station accommodating mobile terminals and a backbone network.
