We can store frequently accessed data into a cache. The client can query the cache first instead of visiting the database directly. If there is a cache miss, the client can query from the database. Caches like Redis store data in memory, so the data access is much faster than the data...
You might wonder where the Internet came from; it seemed to take off virtually overnight. In fact, the vital piece of infrastructure on which the Net is built was already in place and had been invented back in the 1860s. I'm referring, of course, to thetelephonesystem. When computer ne...
Cisco IOS and Cisco IOS XE gateways utilize a concept of a dial-peer to control call routing and capabilities negotiation for each leg of a call. A call leg is the bidirectional communication between two call agents. A call agent is a device that initiates, processes, or for...

It addresses HOL issue through request multiplexing, which eliminates HOL blocking at the application layer, but HOL still exists at the transport (TCP) layer. As you can see in the diagram, HTTP 2.0 introduced the concept of HTTP “streams”: an abstraction that allows multiplexing different ...
Cisco IOS- en Cisco IOS XE-gateways maken gebruik van een concept van een dial-peer om de oproeproutering en de onderhandeling van functies voor elk onderdeel van een oproep te controleren. Een call leg is de bidirectionele communicatie tussen twee call age...
