This encrypted packet is then encapsulated within the VPN protocol layer, allowing secure communication with the VPN server. Option 121, also known as the Classless Static Route Option, allows network administrators to define classless static routes for clients, specifying routes with both the destination subnet and the gateway address.

In simple terms, Border Gateway Protocol (BGP) is the protocol that routes traffic on the Internet. They can then announce the routes (groups of IP addresses) that they own from their ASN. During a BGP route hijack, an attacker advertises IP prefixes from an ASN that is not the normal originator.

What protocols do the devices use to communicate? For delivering this data one widely used protocol is MQTT. MQTT is a lightweight messaging protocol for pub/sub communication typically used for Machine-to-Machine (M2M) communication. How many devices will be creating information? How will they send that information back?

SASE merges the network optimization capabilities of SD-WAN with a full security stack, including Next Generation Firewall (NGFW), Secure Web Gateway (SWG), Zero Trust Network Access (ZTNA), and more. Each AS advertises which IP addresses it can route traffic to, helping traffic move from its source AS to the AS closest to its destination.

SASEs built-in SD-WAN functionality offers network optimization, while the integrated security stack including Next Generation Firewall (NGFW), Secure Web Gateway (SWG), Zero Trust Network Access (ZTNA), and more secures traffic over the corporate WAN. Often, the protocol is referred to as SSL/TLS.

They heavily rely on BGP (Border Gateway Protocol, the protocol that networks use to exchange routes) to define which cache an end user is directed to. The request to play a movie is made to the CDN, which replies with an IP address for the cache that will serve the movie without using the DNS system.

NGFW also supports the creation of custom application definitions to enable identification of specific apps based on TCP/UDP port, IP address, or domain. Secure Web Gateway SWG helps mitigate social engineering attacks like phishing and protects against Internet-borne malware. ZTNA allows enterprises to do just that.

Designed before the dawn of the commercial Internet, the Border Gateway Protocol (BGP) is a policy-based routing protocol that has long been an established part of the Internet infrastructure. eBGP: the protocol used by border routers to advertise routes. BGP Basics: Routes, Peers, and Paths.

They heavily rely on BGP (Border Gateway Protocol, the protocol that networks use to exchange routes) to define which cache an end user is directed to. In the case of Open Connect and similar BGP-based mappings, the ISP has optimal control if the IP addresses used by the end users are regionalized. Give me movie 2.

Latency : Missing packets in connection-oriented protocols such as TCP and QUIC result in lost packets getting resent. You have to remember that ping rides on top of ICMP, and in a congested network it is one of the first protocols to get dropped by a busy router.
