When more of the workforce shifts to working remotely, it puts new and different strains on the infrastructure across different parts of the network, especially where VPN gateways connect to the network edge. Another strategy is to increase visibility into the traffic flowing between the network edge and VPN gateways and optimize performance.

In this blog, we will explore what static routes are, how they differ from dynamic routes, and how to configure them on routers like Cisco devices. This characteristic makes them efficient for routers with limited processing capabilities. A static route is a manually configured path in a routing table.

Traffic processing engines are at the core of many networking and security products including routers, SD-WAN devices, next generation firewalls, secure web gateways, IPS , CASB/DLP, and ZTNA products. The answer is: core capabilities should be built once and be leveraged to address multiple functional requirements.

Thus, despite the industry hype, NFV will largely look like the managed or hosted firewalls and other devices of the past, with some incremental benefits from using virtual instead of physical appliances. These may be any network function, such as SD-WAN, firewalls, IPS/IDS, secure web gateways and routers.

At the core of NFV is the notion that network functions, such as SD-WAN , firewalling and secure web access, can be delivered as virtual appliances and run either on premises (vCPE) or at the carrier core data centers (hosted). Some VNFs, such as routers and SD-WAN, consume relatively few resources.

Maintaining network connectivity with BGP Border Gateway Protocol (BGP) is a routing protocol that connects different networks over the internet. It is used to maintain network connectivity by helping routers find the best path for traffic to travel through.

These were largely untouched by the cloud and dominated by appliance-based solutions (routers, firewalls, etc.). Customers were looking to move away from their MPLS networks and the backhauling of Internet traffic to a secure internet gateway at the datacenter.

SD-WAN appliances include basic firewalls, but those firewalls lack the threat protection needed by today’s enterprises. Branch firewalls offer more capabilities, but their capacity constraints limit inspection capabilities for CPU-intensive operations, such as SSL decryption, anti-malware, and IPS. .

Visibility -- Historically enterprise networks had a router/firewall connected to the WAN as a gateway. Monitoring traffic flows could be a real challenge if the packets don’t always flow through the WAN gateway. Will a BYOD mentality pervade that sidesteps this convention?

Their MPLS configuration also required a stack of appliances firewalls, routers, and WAN optimization at each site that added costs and complexity. Other than the datacenter and four stores, none of the locations had firewalls to protect them against malware and other attacks.

Appliances such as routers, firewalls, secure web gateways (SWG) and intrusion prevention systems (IPS) have well-earned reputations of being extremely sensitive to updates.
